Drugmand (IRSN); the Canadian National Col- lections of Insects, Arachnids and Nematods, Ottawa, Dr. A. Smetana and Dr. A. Davies (CNC), and, in particular, the Natural History Museum and Biodiversity Research Center of the University of Kansas, Lawrence, Kansas, Dr J. S. Ashe (SEMC). METHODS All measurements were made using a ocular mi- crometer. Total body length was determined by sum- ming the individual lengths of the tagmata. Measure- ments of the tagmata were performed as follows: head- length along the midline between font margin and neck; width between the eyes including eyes. Pronotum. — length along the midline; width at the widest part. Elytra. — length from shoulder to posterior angle; width in the middle. Abbreviations for collections containing the speci- mens used in this study are given in the acknowledg- ments. My own collection is abbreviated UIC. TAXONOMY Lispiniis ashei new species (Figs. 5a-f) Holotype. — Honduras: Ocotepeque: 24 km E. Ocote- peque. El Guisayote, 14. VI. 1994, 2170 m, 14°25' N, 89°04' W; J. S. Ashe and R. Brooks collectors; male, under bark (SEMC). Paratypes. — Two males and two females (SEMC), one male and one female (UIC), all with same data as the holo- type Diagnosis. — The species is similar to the slightly larger Lispimis cordilliensis in microsculpture and punctuation of pronotum and elytra, and the antennae. The endophallus of the aedeagus has fewer coils than in L. cordilliensis and the paramera seems to lack the lateral membranous lobe. Apically, the spermatheca is without a straight part and has only one torsion. The species also resembles L.fiingicola in the nature of the aedeagus and spermatheca, but L. ashei is larger. Description. — Length: 5.2 mm. Color: Black; last ab- dominal tergite reddish; legs and antennae red. Head: 0.6 mm long, 0.8 mm wide; distinctly and densely punctuate; distance between punctures shorter than diameters of punctures; surface with sparse micropunctulation; two setae between anterior edge of eyes inserted in small round depressions; surface shiny, with weak microsculpture transversely reticulate apically, longitudinally reticulate laterally and on neck. Antennae: Antennomere 3 scarcely longer than 2, 4th antennomere slightly longer than wide, 5th quadrate, antennomeres 6-10 scarcely wider than long. Pronotum: 0.7 mm long, 0.9 mm wide; midline wide, smooth, with indistinct transverse depression in front of posterior edge; depressions at posterior angles distinct, not sharply delimited from lateral margin and disc; lateral sides of pronotum curved, slightly emarginate in front of poste- rior angles; surface of pronotum shiny, with punctuation deeper and about as dense as that on head, with sparse micropunctulation and with microsculpture similar to that on head, but slightly denser. Elytra: 1.1 nun long, 1.0 mm wide; punctuation equally deep but sparser than that on pronotum; punctures indistinctly longitudinal; each elytron with indistinct coriaceous row of punctures; sur- face of elytra slightly less shiny than that of pronotum; microsculpture longitudinally reticulate, denser and deeper than that on pronotum. Abdomen: densely punctu- ate with transversely reticulate microsculpture. Etymology. — The species is dedicated to Dr J. S. Ashe, who collected it during one of his numerous excursions to the neotropics. Lispinus beni new species (Figs. 4a-f) Holotype. — Bolivia: Beni: Beni Station, Palm camp, NE of San Borja, 3. August 1988, male, under bark, BIOLAT- SI/MAB, larvae in EtOH collection (SEMC) Paratypes. — Bolivia: Beni: Six males, five females (SEMC), one male, one female (UIC), all with data same as the holotype Diagnosis.-The species is similar to Lispi)nis listenbarthi in size, punctuation, and microsculpture. The endophallus of the aedeagus is more simple and the sclerotized part of the ductus of the spermatheca is much shorter and straight. The species belongs to the group of L. tardus Sharp (1887) that is characterized by a bilobed paramera with a sclero- tized outer lobe and a thin transparent inner lobe. The pronotum of the species in this group is more or less straightly narrowed from the front angles to the posterior angles. Description. — Length: 4.0 mm. Color: Black; posterior margin of abdominal tergites reddish; antennae piceous; legs red. Head: 0.5 mm long, 0.6 mm wide; distinctly, and sparsely punctuate; distance between punctures greater than diameters of punctures; surface of clypeus with trans- verse reticulate microsculpture; surface of disc slightly shiny, with netlike microsculpture on disc, longitudinally reticulate laterally; two large punctures with setae in in- distinct depressions between eyes.

Lispinus ftmgicola new species (Figs. 6a-f) Holotype. — Peru: Mndre de Dios: Cusco Amazonico, Provincia de Tambopata, 15 km NE Puerto Maldonado, 18 July 1989, elevation 200 m, J. S. Ashe & R. Leschen *555, male, collected from encRisting fungi (SEMC). Paratypes. — Two females (SEMC) and one male (UIC) with same data as holotype; Peru: Hwiimco:, Panguana, Biological Station, 74°56' W, 9°37'S, 21 January 1975, fe- male, collected by Hanagarth (UIC). Diagnosis. — The species resembles Lispiiiiiis venezuelaiius and L. listeubnrthi, but punctuation of pronotum and elytra of L. fungicola is sparser and the microsculpture is more longitudinally reticulate. The aedeagus of L. fungicola is similar to that of L. listenbarthi; however, the spermatheca is totally different. Furthermore the pronotal sides are curved in L. fungicola. It is also simi- lar to the larger L. asliei. Description. — Length: 4.2 mm. Color. Black; abdomi- nal tergites reddish at posterior edge; antennae and legs red. Head: 0.5 mm long, 0.7 mm wide; distuictly, but not densely, punctuate; distance between punctures as great as, or greater than, diameters of punctures; clypeus with dense transversely reticulate microsculpture; surface of disc moderately shiny; rtucrosculpture more longitudinally reticulate; two setae in indistinct depressions between an- terior edges of eyes. Antennae: Antennomere 3 longer than 2; Antennomeres 4 — 6 quadrate; Antennomeres 7-9 dis- tinctly wider than long; Antennomere 10 longer than preceeding antennomeres. Pronotum: 0.65 mm long, 0.85 mm wide, with smooth midline; depressions at posterior edge distinct, but not delimited from lateral margin; lat- eral sides curved in anterior part, in front of posterior angles scarcely narrowed; surface with distinct but sparse punctuation; distance between punctures greater than di- ameters of punctures; micropunctulation sparse; surface scarcely shiny, with microsculpture longitudinally reticu- late. Elytra: 0.9 mm long, 0.9 mm wide; punctuation as on pronotum; punctures slightly longitudinal; surface shiny, with the longitudinally reticulate microsculpture slightly deeper than that on pronotum. Abdomen: distinctly and densely punctuate, punctuation sparser at posterior edge of tergites than at base; microsculpture transversely reticu- late. Etymology. — The specific name is derived from the Latin fungus and cola meaning living in fungi. Lispinus jamaicensis new species (Figs. 7a-f) Holotype. — Jamaica: St. Andrew Parish, Parque Hardwar Gap, elevation 4009 ft (1237 m), 76°42' W, 18°04' N, 16 December 1973, male, under bark, collected by. S. and J. Peck (CNC). Paratypes. — Three males and five females (CNC), one male and one female (UIC) with same data as holotype. Diagnosis. — The species is similar to Lispinus fungicola in the structure of the spermatheca and microreticulation of the elytra. It is conspicuously different by the absence of the two deep punctures on the disc of the head and endophallus of the aedeagus with more coils. It also re- sembles the larger L. asliei, but the spermatheca has fewer coils, and the paramera is wider with a small transparent lateral appendix. Description. — Length: 4.6 mm. Color: Black, legs pi- ceous. Liead: 0.5 mm long, 0.65 mm wide; punctuation of head distinct; punctuation on clypeus denser than that on disc; distance between punctures as great as, or greater than, diameters of punctures; surface shiny, with distinct microsculpture transversely reticulate on the clypeus, longitudinally reticulate laterally and netlike reticulate on disc; coriaceous netlike reticulation laterally behind eyes. Antennae: Antennomere 3 distinctly longer than 2; Anteiinomeres 4-5 quadrate; last antennomeres wider than long. Pronotum: 0.6 mm long, 0.8 mm wide, with small smooth midline in posterior half; lateral sides widest at anterior edge, scarcely narrowed to the posterior angles, slightly emarginate In the posterior third, with several se- tae along the lateral margin; depressions at posterior angles deep, distinct; surface moderately shiny, densely and dis- tinctly punctuate; pumctures deeper than on head; distance mostly not greater than diameters of punctures; microsculpture longitudinally reticulate; surface of poste- New Staphylinid Beetles Figs. 4-6. 4. — Lispinus beni, 5. — Lispinus aslwi, 6. — Lispiniis fimgicolci; a: front body, b: microsculpture and punctuation of pronotum, c: microsculpture and punctuation of elytra, d: antenna, e: aedeagus in lateral and dorsal view, f: paraniera, g; spermatheca (line a, d: 1 mm; b, c, e-g: 0.1 mm).

Eh/trn: 0.95 mm long, 1.0 mm wide, with longitudinal punctures; pimctuation less deep and sparser than on the pronotum; surface dull, with microsculpture dense and distinct, more distinct than on pronoti.im; each elytron with one deeper puncture with seta in the anterior third of disc. Abdomen: Punctuation weak, sparser than on pronoti-im; punctuation on abdominal tergites 1-4 denser than that on tergites 5 and 6; microsculpture netlike at base of abdominal tergites and partly transversely reticulate at posterior edge. Etymology. — The specific name is derived from the island of Jamaica where the species was collected. Lispinus lescheni new species (Figs, la-f) Holotype. — Peru: Madre de Dios: Cusco Amazonico, Provincia de Tambopata, 15 km NE Puerto Maldonado, 9 July 1989, elevation 200 m, J. S. Ashe and R. Leschen, # 454, male, collected from fungus (Schizopom) (SEMC). Paratypes. — Two females (SEMC) and one male (UIC) with same data as the holotype. Diagnosis. — This species is totally different from all other known neotropical Lispinus by having transverse reticulation on the elytra and abdominal depressions. The transverse reticulate microsculpture of the elytra is simi- lar to that in neotropical Neolosus; however, I could not find the hypomeron line of the pronotum characteristic of Neolosus. Description. — Length: 3.8 mm. Color: Piceous; last ab- dominal segments with reddish tint; antennae and legs red. Head: 0.5 mm long, 0.7 mm wide; densely and finely punc- tuate; distance between punctures greater than diameters of punctures; surface sparsely micropunctuate; microsculpture weak, transversely reticulate apically, lon- gitudinally reticulate posteriorly; surface shiny, nearly polished; two setae between anterior edges of eyes in in- distinct, round depressions. Antennae: Antennomere 3 dis- tinctly longer than 2; Antemiomeres 4 and 5 longer than wide, Antennomere 6 quadrate; Antennomeres 7-10 slightly wider than long,. Pronotum: 0.55 mm long, 0.85 mm wide; depressions at posterior angles distinct, clearly delimited from disc and uniformly curved lateral margin, distinctly less punctuate than head; distance between punc- tures greater than diameters of punctures; sparsely micropunctuate except for smooth midline; microsculpture weak, consisting of longitudinal undulations; surface shiny. Elytra: 0.8 mm long, 0.85 mm wide; punctuation as on pronotum; microsculpture weak, transversely reticulate at base, more netlike reticulation at posterior edge; surface shiny, nearly polished. Abdomen: finely punctuate; microsculpture transversely reticulate; abdominal tergites with distinct transverse depression in middle of base. Etymology. — The species is dedicated to Richard Leschen who, with J. S. Ashe, collected this species. Lispinus malliformis new species (Figs. 3a-f) Holotype. — Brazil: Ceard: with the following labels: "Museum Paris, Bresil, Etat de Ceara, Env. de Baturite, leg. A. Michelin, 1906", a second label: "dans Manitiot glazco\/i." Male (IRSN). Diagnosis. — This species resembles Lispinus bolivianus (identified by A. Fauvel as L. bolivianus) by having long, deep, and dull depression on the posterior angles of the pronotum, but it is much longer than L. bolivianus. Par- ticularly the form of the aedeagus characterizes the spe- cies. The aedeagus of L. malliformis is unique among neotropical Lispinus; the upper part has a wide bridge that is nearly twice as wide as the diameter of the aedeagus. Description. — Length: 4.1 mm. Color: Black; elytra dark piceous; posterior margin of 5th and 6th abdominal seg- ment reddish; antennae brown. Head: 0.5 mm long, 0.6 mm wide, distinctly and densely punctuate; fine micropunctulation between the coarse punctures; distance between punctures greater than dianieters of punctures; surface shiny, with weak microsculpture, transversely re- ticulate on the front head, longitudinally reticulate on the posterior head; dense coriaceous microreticulation behind eyes; two round, relatively deep, distinct depressions be- tween eyes. Antennae: Antennomere 2 round; Antennomere 3 conical; Antennomeres 4-6 quadrate. Pronotum: 0.5 mm long, 0.7 mm wide; lateral sides nearly parallel, slightly narrowed from anterior angels to posterior angles, dis- tinctly emarginate in front of posterior angles; depressions at the posterior angles deep and long, much longer than half the length of pronotum; outer margin of depressions distinct, sharply delimited from lateral margin; punctua- tion more distinct and denser than that on head, with nearly coriaceous punctures near the posterior margin; surface shiny, with moderately dense microsculpture lon- gitudinally reticulate; depressions at posterior angles with distinct microreticulation; surface of depressions dull. Elytra: 0.8 mm long, 0.7 mm wide; punctuation finer and sparser than on the pronotum; distance between punctures greater than diameters of punctures; each elytron with two rows of deep longitudinal punctures between shoulders and posterior margin, not forming longitudinal depres- sion; microsculpture dense, distinct, longitudinally reticu- late; indistinct transverse depression behind mesonotum. Abdomen: Distinctly punctuate; punctures at lateral sides deeper and denser than on disc, with more or less distinct longitudinal transverse ridges laterally; surface moderately shiny, with netlike microsculpture; lateral sides with long yellow hairs; particularly at base of abdominal segments with a transverse row of yellow hairs.

Anderson, VENl A98 038, one male and one female, under dead leaves (SEMC, UIC); Tdchira: San Cristobal, 10 km SB Parque National Chorro El Indio, elevation 1370 m, 7°44'3" N, 72° 13'!" W, 30 May 1998, collected by J. S. Ashe, R. Brooks, R. Hanley, VENl ABH98 164, one male and two females, under bark (SEMC). Diagnosis. — This species resembles Lispinus sobriniis in microsculpture and distal part of endophallus of aedeagus. As in the related species, L. sobriuiis and L. sobrinuUus, the endophallus of the aedeagus distally con- tain a funnel-like structure. However, L. psetidosobrinus is much smaller than L. sobrinus, and the endophallus of the aedeagus has many more coils than L. sobrinus and L. sobrinuUus. Description. — Length: 5.4 mm. Color: Black; legs yel- low; antennae piceous; last abdominal tergite reddish. Head: 0.6 mm long, 0.9 mm wide; front margin evenly emarginate in the middle; punctuation distinct; distance between punctures about as great as diameters of punc- tures; the usual setae at the apical and lateral margin; two setae between eyes in indistinct depressions; surface shiny, with weak microsculpture transversely reticulate. Anten- nae: Antennomere 3 scarcely longer than 2; Antennomeres 4-6 quadrate; subsequent antennomeres scarcely wider than long. Proitotuin: 0.75 mm long, 1.0 mm wide; widest in the middle; lateral sides nearly parallel in the apical half and scarcely narrowed to front angles, emarginate in the basal half, with deep depressions at posterior angles; punc- tuation distinct; distance between punctures as great as, or greater than, diameters of punctures, with indistinct smooth midline; punctuation near posterior edge slightly deeper and denser than that on disc; surface with scattered micropunctures; surface shiny, with weak microsculpture longitudinally reticulate; surface of posterior depressions moderately shiny, with denser microsculpture than that on disc. Eli/tra: 1.1. mm long, 1.1 mm wide; punctuation much sparser and weaker than that on pronotum; surface scarcely shiny; microsculpture netlike reticulate, more dis- tinct than that on pronotum; two setae on disc and several setae on lateral side. Abdomen: Segments distinctly and densely punctuate at base, sparser punctuation on poste- rior edge of abdominal tergites. Etymology. — The suffix pseudo- meaning similar refers to the similarity to L. sobrinus Fauvel, 1865, that was col- lected near Caracas, Venezuela. Remarks. — A key to the related species, Lispinus pseudosobrinus, L. sobrinus, and L. sobriinillus is provided after the description of L. sobrinuUus. Lispinus qiiadrisetiis new species (Figs. lOa-f) Holotype. — Costa Rica: San Jose: Zurqui de Moravia, elevation 1600 m, 10°3'0"N, 84°1'0"W, 1-30 March 1996, collected by. P. Hanson, CRl H95-96 04, male in a flight intercept trap (SEMC). Paratype. — One male with same data as the holotype (UIC). Diagnosis. — This species resembles Lispmuis strictus by the row of four setae on the elytra, but L. quadrisetus is slightly longer and the punctuation of the elytra is slightly finer and sparser than in L. strictus. Furthermore, the endophallus of the aedeagus is totally different; there is only one large coil of the unusual broad endophallus in L. quadrisetus. Description. — LengtJi: 5.4 mm. Color: Black; antennae piceous; legs yellow; last abdominal tergite reddish. Head: 0.7 mm long, 0.8 mm wide; punctuation distinct, moder- ately dense, average distance between punctures greater than diameters of punctures; microsculpture dense and distinct, transversely reticulate on clypeus, netlike reticu- lation on disc; the usual setae along front and lateral mar- gin, relatively long; distance between interocular setae greater than between each seta and eye; one or two shorter setae between posterior supraocular seta and the long neck seta. Antennae: Antennomere 3 scarcely longer than 2; Antennomeres 4-6 quadrate; subsequent antennomeres slightly wider than long. Pronotum: 0.75 mm long, 0.9 mm wide, widest in anterior half, scarcely narrowed to front angles, but narrowed straightly to posterior angles; depres- sions at posterior angles distinct, with several long yellow setae along front and lateral margin and a long apical seta at posterior depressions; punctuation on disc as deep as, but sparser than, that on head; distance between punctures conspicuously greater than diameters of punctures; sur- face slightly shiny, with microsculpture fine, dense, longi- tudinally reticulate; punctuation and microsculpture of depressions as that on disc.

Brooks #056, male, under bark (SEMC). Paratype. — One female with same data as the holo- type (UIC). Diagnosis. — This species is similar to Lispinus sobrimis in the structure of the aedeagus. It contains the same api- cal funnel-like structure and nearly the same torsion struc- ture of the endophallus. However, L. sobrinuUiis is much smaller than L sobrimis; the microsculpture of the elytra is much deeper and more longitudinally reticulate. Further- more, microsculpture on the pronotum is weaker and on the elytra deeper in L. sobrinuUus than in L. sobrimis. Description. — Length: 5.4 mm. Color. Black; antennae piceous; legs yellow; last abdominal tergite reddish. Head: 0.6 mm long, 0.8 mm wide; pimctuation deep, moderately dense, with distance between punctures about as great as diameters of punctures; with micropunctulation; surface shiny, with weak microsculptvire transversely undulate; with the usual setae along front margin, two setae between eyes and one seta between eyes and neck. Antennae: Antennomere 3 scarcely longer than 2; Antennomeres 4-6 quadrate; subsequent antennomeres slightly wider than long, Pronotum: 0.75 mm long, 0.9 mm wide, widest near front angles; lateral sides more or less parallel in anterior half, distinctly narrowed in posterior half; sides not emar- ginate in front of posterior angles; pimctuation deep, dense, denser at front angles and in front of posterior edge than on disc; midline indistinct, smooth; punctuation sparser at both sides of midline; surface shiny, with weak microsculpture longitudinally undulate; with scattered micropunctulation; microsculpture along posterior edge and within posterior depressions more distinct. Elytra: 1.1 mm long, 1.05 mm wide; punctuation nearly as deep and only slightly sparser than that on pronotum, moderately coriaceous near lateral sides; microsculpture longitudinally reticulate, much more distiiict and deeper than that on pronotum and head. Abdomen: Coarsely pimctuate on basal part of anterior tergites; sparser and finer punctuation on posterior edge of tergites. Etymology. — The specific name sobrinullus is the di- minutive of sobrimis and refers to the similarity to L. sobrimis Fauvel, 1865. Remarks. — The three species of the Lispinus sobrimis group from Venezuela can be differentiated in the follow- ing key. The main character of the group is the tube or funnel-like structure of the apical endophallus of the aedeagus. The spermatheca is simple without a long ductus.

Larger species, 6.0-6.3 mm long; punctuation on pronotum finer than on elytra L. sobrinus Smaller species, 5.2-5.3 mm long; punctuation on elytra as fine as, or finer than, that on pronotum 2 2. Punctuation on pronotum deep; distance between punc- tures as great as, or shorter than, their diameters L. sobrinullus Punctuation on elytra and pronotum weak; distance between punctures much greater than diameters of punctures on pronotum L. pseudosobrinus Lispinus ventralis new species (Figs. 2a-f) Holotype. — Bolivia: Yuracaris, male (IRSN) Paratype. — One male with the same label as the holo- type (IRSN). Diagnosis. — This species is similar to Lispinus caimlis in length, punctuation, and microsculpture. It differs from L. canalis by the form of the pronotum, the anterior one third of which is curved to the front angles, whereas it is straightly narrowed from the front angles to the poste- rior angles in L. canalis. The most conspicuous charac- ter is the wide paramera of the aedeagus and the thick antennae. Description. — Length: 5.2 mm. Color: Black; antennae piceous; legs rufotestaceous; posterior margin of pronotum red; elytra piceous; posterior margin of abdominal terg- ites red; last abdominal tergite light red. Head: 0.6 mm long, 0.8 mm wide, distinctly and densely pimctuate; distance between punctures about as great as diameters of punc- tures; surface shiny, with weak microsculpture transversely reticulate; on each side of the middle between the eyes with a round depression with a moderately long hair; distance between depressions about twice as great as the distance to the eye. Antennae: Thick; Antennomere 2 short, slightly wider than long; Antennomeres 4 and 5 quadrate; subse- quent antennomeres wider than long; Antennomeres 7- 10 twice as wide as long. Pronotum: 0.8 mm long, 0.95 mm wide; lateral sides curved in anterior one third to anterior angles, straightly narrowed in posterior half, scarcely emar- ginate in front of posterior angles; smooth midline about three-fourths as long as pronotum, not reaching front mar- gin; disc with distinct pimctuation; punctures deeper than those on head, particularly on each side of the midline; punctuation moderately dense, with distance between punctures more or less similar to that on the head, but less dense at lateral sides and inner part of posterior depres- sions; a more coriaceous punctuation on posterior depres- sions; surface moderately dull; microsculpture longitudi- nally reticulate, dense, more distinct than on the head. New Staphylinid Beetles 11 Elytra: 0.95 mm long, 1.05 mm wide; punctuation much weaker and sparser than that on pronotum; surface dull, with microsculpture longitudinally reticulate, netlike re- ticulation on the anterior one third; microsculpture more distinct and denser than that on pronotum; indistinct depression lateral to suture behind mesonotum. Abdo- men: Densely and coarsely punctuate; surface moder- ately shiny, with weak microsculpture; yellow hairs relatively short. Etymology. — The species was labelled (but not pub- lished) as Lispiiiiis ventmlis by C. Fauvel; 1 have used the same name, which is derived from the Latin venter, mean- ing abdomen and possibly refers to the coarsely punctu- ate abdomen. Remarks. — I could not find Yuracaris. A village named Yura is located in the Departamento de La Paz at 66°21' W, 19°42' S, but I am unsure if it is the same as Yuracaris. Neolosus cochabambae new species (Figs, lla-f) Holotype. — Bolivia: Cochabambn: 16.7 km W Villa Tunari, Parque Machias, elevation 300 m, 16°58' 20" S, 65° 24' 42" W, 12 February 1999, collected by R. Anderson, BOL 1A99037, male, in lowland rain forest (SEMC). Paratype. — Three females (SEMC), and one male and two females (UlC) with same data as the holotype. Diagnosis. — This species can scarcely be differentiated from the related species of the Neolosus zischkai group by external characters. Only the structure of the aedeagus is characteristic in having an asymmetrical middle lobe. The species of the N. zischkai group are characterized by smooth elytra with a row of only two setae on the disc, whereas the species of the N. trichidus group are characterized by two rows with at least four setae each (Irmler 1999). Description. — Length: 6.2 mm. Color: Black. Head: 0.6 mm long, 0.8 mm wide, with fine, sparse punctuation; dis- tance between punctures much greater than diameters of punctures; surface shiny, with microsculpture transversely reticulate; two supraocular setae; two more setae behind posterior supraocular seta; eyes as long as temples. Anten- nae: Antennomere 3 scarcely longer than 2; Antennomere 4 globular; Antennomere 5 quadrate; subsequent antennomeres slightly wider than long. Pronotum: 0.75 mm long, 1.1 nun wide, widest shortly behind anterior angles; lateral sides scarcely narrowed to posterior angles; front edge deeply emarginate; front angles distinctly prominent; depressions at posterior angles deep, reaching the middle; several setae along lateral margin; punctuation as fine and sparse as that on head; midline short, smooth; surface shiny, with microsculpture more or less longitudinally re- ticulate on anterior half, transversely reticulate on poste- rior half. Eh/tra: 1.15mm long, 1.25mm wide; punctuation finer and sparser than that on pronotum; surface shiny, with microsculpture transversely reticulate; large puncture with seta near posterior third of disc. Abdomen: Distinct diagonal strigae at lateral sides; only a moderately wide space on middle of tergites smooth; microsculpture trans- versely reticulate. Etymology. — The specific name refers to the Bolivian Departamento de Cochabamba. Key to the Species of the Neolosus zischkai Group 1 .
