R. Tamsitt,2 and Dario Valdivieso3 m Oi r>- Ui — * CO CO C\J in — ^ lO ARI o z — (O \j r^ ^ ■ CO Abstract — Three new species of labidocar- pine mites (Listrophoroidea, Chirodiscidae) are described from Puerto Rican bats. The new species and hosts are Lawrenceocarpus puertoricensis sp. n. from Brachyphylla cavernarum, Paralabidocarpus foxi sp. n. from Artibeus j. jamaicensis, and Paralabi- docarpus stenodermi sp. n. from Stenoderma rufum darioi. The only publication treating listrophorid mites from Puerto Rican bats was by Tam- sitt and Fox (1970), who reported the species Paralabidocarpus artibei Pinich- pongse (1963), Dentrocarpus (=Dentocar- pus) silvai Dusbabek and Cruz (1966), and Lawrenceocarpus micropilus Dusbabek and Cruz (1966). We examined part of the collection studied by Tamsitt and Fox and additional material, and mites reported by these authors as L. micropilus and P. artibei were found to represent three new species, described here (Figs. 1-4). The chaetotaxy nomenclature is that of Fain (1970b), and where applicable, his designations are given in parentheses after referring to setae. Al- though other classifications for listrophorid mites have been proposed (see McDaniel, 1968), we follow Fain (1971) by consider- ing the Listrophoroidea to be a superfamily containing the family Chirodiscidae and the subfamily Labidocarpinae. Materials and methods — We examined re- cently killed and preserved bats under a dissecting microscope, removed mites at- tached to hairs, fixed them in 70% ethanol and, after mounting specimens in Hoyer's medium, studied them by bright-field and interference-contrast (Normarski phase) microscopy. For scanning electron micro- scopy, we mounted hairs with affixed mites onto aluminum stubs with 3M adhesive transfer tape (Minnesota Mining and Manu- facturing Co., London, Ontario). Specimens were air dried, coated with gold (about 20 nm thick) in an Edwards Model 4 vacuum evaporator (Edwards High Vacuum, 1 Instituto de Zoologia, Academia de Ciencias de Cuba, La Habana, Cuba. - Department of Mammalogy, Royal Ontario Museum, and Department of Zoology, University of Toronto. 3 Department of Mammalogy, Royal Ontario Museum. pig. i — Lawrenceocarpus puertoricensis sp. n. a.

We measured mites with a calibrated ocular micrometer; mea- surements are given in micrometres (/>im). In the descriptions that follow, measure- ments of paratypes are given in parentheses after those of the holotypes.

Ten paratype females (acc) and two para- type larvae (acc), same host and locality as other paratypes. Other material (rom) studied: eight females, five males, three lar- vae from typical host (rom 44600), col- lected by M. Brock Fenton, Aguas Buenas Caves, near Aguas Buenas, Puerto Rico, 13 February 1968; three females, one male, from typical host (rom 44726), collected by T. E. Rogers, Cueva Honda, near Agua- dilla, Puerto Rico, 3 March 1968. Remarks — Lawrenceocarpus puertoricensis differs primarily from L. micro pilus Dusba- bek and Cruz (1966) by larger size (length of females 665 and 408, respectively; length of males 425 and 290, respectively), num- ber and position of opisthosomal setae in both sexes, the presence of a leaflet-shaped seta on tarsus m in L. puertoricensis (absent in L. micro pilus) , the shape of the accessory spur of tarsus iv (straight in L. puertori- censis, curved in L. micropilus) , shape and position of the male copulatory organ, shape of coxal apodeme i, and shape and position of legs ii-iv of copulatory female. L. puerto- ricensis is similar to L. dusbabeki Cruz (1969) but differs from it by larger size (length of females 665 and 433, respec- tively; length of males 425 and 319, respec- tively), shape of the claws, the relative shape and size of the copulatory organ of the male, the shape and position of legs ii-iv of the copulatory female, and by hysterosomal setae in the larva. From L. lobus McDaniel (1970) L. puertoricensis differs by the less marked development of the posterior projections of the propodoso- mal plate, by the chaetotaxy of the body, and by larger size (length of females 665 and 360, respectively; length of males 425 and 246, respectively). The new species is distinguished as well from L. mimon Fain (1970a) by larger size (length of females 665 and 510, respectively; males of L. mimon unknown), by the presence of the leaflet-shaped seta of tarsus iv (absent in L. mimon), and by the chaetotaxy of the body. From L. phyllostomus McDaniel (1972) L. puertoricensis differs by smaller size of the male (length 425 and 520, re- spectively), larger size of the female (length 665 and 623, respectively), number and position of opisthosomal setae, and the presence of a leaflet-shaped seta on tarsus in (seta unmodified in L. phyllostomus). We also distinguished in our material an eight-legged stage (probably a nymph similar to that described by Dubinina, 1964, for Histiophorus sp.) that differs from females only by smaller size (length 391-541, height 118-198) and by the slightly greater num- ber of annulations (49-54). Lawrenceocarpus puertoricensis, known only from the type host in Puerto Rico, is common on hairs of the dorsum of the inter- femoral membrane, forearm, and wing mem- brane posterior and proximal to the forearm. Paralabidocarpus foxi sp. n. (Figs. 3a, B, 4e,f) Paralabidocarpus artibei, Tamsitt and Fox, 1970, p. 399 (in part; not P. artibei Pinich- pongse, 1963). Female (holotype) (Fig. 3a) — Length of body 429 (382-429), height of body 99 (92-105). Body laterally compressed, bear- ing 48 (43-49) fine, transverse annulations; edges subparallel but slightly tapered pos- terior to legs iv. Gnathosoma heavily sclerotized, only the strong, chelate chelicerae distinguished. Propodosoma heavily sclerotized, divided into three plates; anterior smallest, sub- triangular; intermediate larger than first, with two prominent dorsal processes; third three times larger than second, also with two prominent dorsal processes, sharply pointed, extending posterodorsally beyond border of body. Legs i and n labidocarpid type, of three segments each. Legs i longer than legs n. Tar- sus i bearing two strong, curved setae on lateroposterior border; tarsus n with only one seta, finer than that of tarsus I, on pos- terodorsal border. Legs in and iv (Fig. 4e,f) separated from legs i and n and approximately in midregion of body, each of four segments. Basal seg- ment of legs in immovable, wider than long; remaining segments decreasing in size and increasing in relative length; third segment bearing a long, stout solenidion; tarsus m with a long, curved claw, two short, thick accessory spurs, rounded at tips, a long, thick pedunculate caruncle, and three fine setae. Legs iv similar to legs in but longer, tar- sus bearing one rather than two accessory spurs. Coxal apodemes m long, fine, heavily sclerotized, joined anteriorly, two-thirds length of leg in. Coxal apodemes iv similar in shape to those of hi, as long as basal seg- ment of leg in. Anus subterminal, ventral. Two pairs of propodosomal setae (sc /, sc e), long and stout (inferior stouter than superior), arising from each end of a small j-shaped plate posterior to last propodosomal plate. Above coxal apodeme in are two pair of long, fine setae (h, sh), inferior shorter and thinner than superior. Anterior to legs iv, on ventral part of body, are a pair of very short, fine setae. At extreme posterior of body, in a conical zone more heavily sclerotized than surrounding areas, are two pairs of long, fine setae, subequal in length (Fig. 3a). Male (allotype) (Fig. 3b)— Length 297, height 1 1 8. Body laterally compressed, wider between legs n and m, robust, with 21 fine, transverse annulations. Propodosomal plates, gnathosoma, and legs as in female, but legs in and iv situated posterior to midregion of body. Copulatory organ consisting of a heavily sclerotized area bearing three pairs of fine setae (dorsal and intermediate setae long, subequal, ventral setae short) and two pairs of anal suckers (one between intermediate and ventral setae, the other below ventral seta). There are two pairs of propodosomal setae (sc i, sc e) and two pairs of metapodo- somal setae (h, sh), the latter dorsal to coxal apodemes in, shape and position as in the female. Copulatory female — Not available for study. Larva — Not available for study. Type data — Holotype female (rom), allo- type male (rom), two paratype females (rom, upr), one paratype female (acc) from Artibeus j. jamaicensis, collected by J. R. Tamsitt and Dario Valdivieso, Luquillo Experimental Forest, near El Verde, Puerto Rico, 12 February 1967, host number rom 40617. Other material (acc) studied in- cludes three females from Stenoderma rujum darioi, from same locality as the holotypes, collected by Robert J. Baker, 20 July 1969, host number ttu 8857. Remarks — Paralabidocarpus foxi differs pri- marily from P. artibei Pinichpongse (1963) by being slightly larger (length of females 429 and 377, respectively; length of males 297 and 265, respectively), by having the inferior pair of setae (sh) near coxal apo- demes in noticeably smaller than the super- ior pair (h), and by the shape of the small plate from which the propodosomal setae (sc i, sc e) arise. From P. tonatiae Fain (1970a), P. foxi differs by being slightly larger (length of females 420 and 429, re- spectively; length of males 285 and 297, respectively) and by not having the gnatho- soma notably more pointed. P. carolliae Fain (1970c) is distinguished from P. foxi by its smaller size (length of females 360 and 429, respectively; length of males 246 and 297, respectively) and by the greater development of the solenidion of leg iv. P. foxi is distinguished from P. macrophyllum Fain (1972) by larger size (length of fe- males 429 and 306, respectively), by the length of the superior seta (h) dorsal to coxal apodeme in (considerably shorter in P. macrophyllum), and by the absence of a sclerotized external projection arising from basal segment n. From P. trachops Fain (1972) P. foxi differs by being larger (length of females 360 and 429, respectively; length of males 285 and 297, respectively), by the considerably longer inferior seta (sh) dorsal to apodeme m (thin and extremely short in P. trachops), and by the relative positions of the propodosomal setae (ventral setae, sc e, far anterior to dorsal setae, sc i, in P. trachops). P. surinamensis Fain (1970c), P. desmodus Fain (1972), and P. antho- rhinae Fain (1973) apparently belong to another group of species, along with P. stenodermi sp. n., in which a sclerotized bar between the propodosomal setae (sc i, sc e) is absent. This mite was found only on hairs of the proximal part of the forearm and ad- joining wing membrane of the hosts. The species is named in honour of Dr. Irving Fox, Professor of Medical Entomol- ogy, School of Medicine, San Juan, Puerto Rico, who has contributed greatly to an understanding of the taxonomy of mites of Puerto Rico. Paralabidocarpus stenodermi sp. n. Paralabidocarpus artibei, Tamsitt and Fox, 1970, p. 399 (in part; not P. artibei Pinich- pongse, 1963). Holotype (female) (Fig. 3c) — Length 449 (402-449), height 138 (125-138). Body robust, laterally compressed, higher poster- ior to legs iv, having 61-63 transverse annu- lations. Only the strong, chelate chelicerae dis- tinguished in gnathosoma. Propodosomal plates three; anterior small, subtriangular; intermediate larger than first, with two prominent dorsal processes, pointed, not surpassing dorsal border of body; the stout, posterior plate extending to level of legs n, almost three times as large as intermediate plate, with two prominent posterodorsal processes, each plate with a short process near posterolateral angle from which arise the lateral propodosomal setae (sc i, sc e) . Legs I and n labidocarpoid, heavily sclero- tized. Legs i with three segments; second seg- ment with a prominent, heavily sclerotized projection on anterior border; tarsal segment with a long, strong seta toward extreme dis- tobasal border. Legs n, also of three seg- ments, smaller than legs i; second segment with a spine-like projection on anterodorsal edge; tarsal segment with a short seta toward posteromedial border. Legs in and iv (Fig. 4c,d) separated from legs I and n, position metapodosomal, each with four segments. Basal segment of legs hi immovable, wider than long, approximately as large as second segment, which is longer than wide; third segment smaller than sec- ond, with a stout solenidion located near extreme posteroventral border; tarsus small, rounded, smaller than third segment, bearing a long, curved claw, three short, fine setae, a caruncle almost as long as tarsus, and two short, thick accessory spurs. Coxal apodemes in long, thin, heavily sclerotized, slightly curved and with an anterior swelling, longer than apodemes iv. Legs iv smaller than legs in, basal segment shorter than that of legs m, seta of third segment fine, tarus with one short accessory spur instead of two, other- wise legs iv similar to legs in. Anus ventral, subterminal. Two pairs of long, stout, opisthosomal setae of subequal length dorsal to anus; two pairs of metapodosomal setae (h, sh) an- terodorsal to legs in, the inferior smaller; a pair of short, fine metapodosomal setae an- terior to base of legs iv, and another similar pair of setae anterior to legs in; two pairs of long propodosomal setae behind propodoso- mal plates, the lower (sc e) arising from posterior plate, larger than upper (sc i). Male — Not available for study. Copulatory female — Not available for study. Larva (Paratype) — Similar to female, from which it differs only by absence of legs iv, dorsal processes of posterior propodosomal plate less prominent, and smaller size (length 356, height 106). Type data — Holotype female (rom) from Stenoderma rufum darioi, collected by J. R. Fig. 4 — Lawrenceocarpus sp. n. and Paralabidocarpus spp. n. a.

Female paratype (acc) and larva paratype (acc) from same host and locality as holotype female, collected by Robert J. Baker, 20 July 1969, host number ttu 8857. Other material (acc) studied includes six females from same host and locality, col- lected by J. R. Tamsitt and Dario Valdivieso, 12 February and 17 July 1967. Remarks — Paralabidocarpus stenodermi is similar to P. surinamensis Fain (1970c), but the two are distinguished by the larger size (length of female P. stenodermi 449; length of "larvigerous" female P. surina- mensis 495; Fain, 1970c, p. 178) and by the short solenidion of the third segment of leg iv of the latter. From P. desmodus Fain (1972), P. stenodermi is distinguished by larger size (length of females 394 and 449, respectively), the shortness of the inferior seta (sh) dorsal to coxal apodeme m, which is three times longer in P. stenodermi, and the relative shortness of the gnathosoma to the propodosomal plates in P. desmodus. From P. anthorhinae Fain (1973) P. steno- dermi differs primarily by larger size (length of females 375 and 449, respectively). P. stenodermi, P. surinamensis, P. desmodus, and P. anthorhinae differ from other species of the genus in the shape of the propodoso- mal plates, in the absence of a sclerotized bar between the propodosomal setae, and in the relative size and disposition of the hys- terosomal setae (sc i and sc e). Hosts were only lightly infested, and mites were found in small numbers attached to hairs on the proximal part of the forearm, adjacent wing membrane, and upper leg.

De P. tonatiae Fain se diferencia por su tamano ligeramente mayor y por no tener el gnatosoma notable- mente mas agudo. P. carolliae Fain se dis- tingue por su tamano menor y por el mayor desarrollo del solenidio de las patas iv. P. foxi se diferencia de P. macro phy Hum Fain por su talla mayor; por la longitud de la seta superior sobre el apodema coxal in (considerablemente mas corto en P. macro- phyllum ) y por la ausencia de la proyeccion externa esclerotizada del apodema coxal n.
