Notes on Acanthocera Macquart (Diptera: Tabanidae)

INTRODUCTION

The genus Acanthocera was proposed by Macquart in 1834 for Tabanus
longicornis Fabricius, 1775. Fairchild (1939) discussed the correct classification
of the specimens studied by Macquart. Loew (1860), Schiner (1866) and Ricardo
(1904) recognized the genus distinguishing it from Dichelacera by the relatively
longer size of the antenna, especially the scape. Lutz (1915) redefined the genus.
Enderlein (1922, 1925), in his revision of the family divided the genus into four,
which were placed in two tribes of the subfamily Diachlorinae based on the
presence or absence of an antennal spine on the first flagellomere, as follows:
Spheciogaster Enderlein and Acanthocera Macquart in Acanthocerini,
Mimodynerus Enderlein and Lutziella Enderlein in Diachlorini. Krõber (1928,
1934) kept this classification except for Mimodynerus, which was synonymized
under Spheciogaster. Fairchild (1939) did not consider Enderlein’s characters
sufficient to establish the genera and he redefined the genus Acanthocera,
placing Spheciogaster and Lutziella under his synonymy. Later (Fairchild, 1969),
he proposed this genus’ division into three subgenera: Acanthocera, Mimodynerus
and Polistimima Fairchild; he also proposed the subgenus Nothocanthocera in
the genus Dichelacera where ten species of Acanthocera were transferred. All
four new species proposed here belong to subgenus Acanthocera.

The morphological tertninology used here are based on McAlpine (1981).

yellow hairs on notopleuron, anepisternum, scutellum and katatergite; abdomi-
nal segments 1 and 2 darker.

Etymology: the specific name refer to scutellum covered with golden hairs.

Acanthocera (Acanthocera) exstincta ; Strickman, 1982: 401 (misident.)

Small sized. Species black with golden hairs on sublateral line, notopleuron,
scutellum, propleuron, anepisternum and katatergite. Eyes pubescent. Antenna
with dorsal tubercle on first flagellomere. Palpus somewhat inflated. Frons wide.
Abdômen with band of yellow hairs on tergites 1 and 2.

Female: length 9,0mm, wing 8,5mm. Frontal index 1.0. Eye with short hairs.
Frons (Fig. 2a) shiny black with pollen above and laterality to basal callus.
Subcallus subshiny brown. Antenna (Fig. 2b): scape and pedicel yellowish
chestnut, flagellum dark brown. Face, parafacial and gena shiny black with bands
of yellowish gray pollen. Palpus (Fig. 2c) brown.

Thorax black with golden hairs on sublateral line, postero-dorsally on
notopleuron and propleuron, dorsally on anepisternum, katatergite and posteri-
orly half of scutellum. Pollen whitish on sublateral line and dorsal portion of
metepimerum. Wing (Fig. 6). Halter brown. Legs: coxae, trocanters and femora
brown to black. Foretibia white on proximal half, remainder brown. Midtibia
white with distai apex chestnut. Hindtibia chestnut to brown with proximal
portion white. Tarsi chestnut to brown. Abdômen black covered with yellow
hairs. Tergites 1-2 and sternite 2 with terminal band formed by whitish pollen
and golden hairs.

Male: similar to the above description except the palpus is porrect, eyes
contiguous and larger body hairs.

Distribution: Brazil (Rio Grande do Sul), Paraguay.

Notes on Acanthocera Macquart (Diptera: Tabanidae)

Type material: Holotype female: PARAGUAY, Itapúa, San Benito, Pastoreo,
2 Mar. 1980, A. Strickman coll., notes 1625, 03-02 # 13, Acanthocera exstincta
(Wied.), det. Fairchild, 1980, left wing in microlamina (FSCA); Paratype female:
same locality, date and collector, 1605 # 8, terminalia absent (MPEG); Paratype
male: BRAZIL, Rio Grande do Sul, 87Km of Porto Alegre, 10 May 1967, Berg

Discussion: this species is closely related to Acanthocera exstincta
(Wiedemann), but it differs by more robust palpus, yellowish scape and pedicel,
darker wing infuscation and just two dorsal golden bands on abdômen.

Etymology: the specific name refers to the two dorsal golden bands on base
of abdômen.

Acanthocera fairchildi sp.n.

Médium sized, 11,0 - 14,4mm. Species black with golden yellow hairs on
sublateral Iine and scutellum. Wing tricolored. Midtibia black. Abdômen with
brown to black hairs and two white band basally.

Female: length, 13,3mm; wing 12,0mm. Eye bare. Frontal index 1.6. Shiny

pollen. Antenna (Fig. 3b): scape, pedicel and base of first flagellomere including
antennal tooth yellowish chestnut, remainder brown to black. Face, parafacial
and gena shiny black with bands of yellowish pollen. Palpus (Fig. 3c) black.

Thorax black with grayish pollinosity, more concentrated on sublateral line
and postero-dorsally on metepimeron. Golden yellow hairs on sublateral line,
postero-dorsally on notopleuron and anepisternum, and scutellum excepting
anterior border. Wing (Fig. 7), costal, radial-1, apex of radial 2+3, apical little
spot joined to radius 4 vein, apical anterior half of basal radial and apex of
posterior cells brown. Anterior half of radial 2+3, radial-5 and posterior cubital
cells yellowish, remainder of wing glass clear. Halter black with brown stem.
Legs black except small proximal area of tibiae and tarsi white. Midtibia with
white hairs. Abdômen black with pollinosity grayish brown excepting subterminal
band on tergiles 1, 2 and 2/3 anterior of tergite 3. Whitish pollinosity on
posterior border of tergites 1 and 2 and sternites 2 and 3. Short golden hairs on
posterior border of tergites 1 and 2.

Male: similar to the above description except the palpus is porrcct, eyes
contiguous and larger body hairs.

Distribution: Brazil (Pará, Amazonas, Rondônia), Peru, Bolivia.

Variations: 3 femalcs from Rondônia and 1 female from Pará present the
third and fourth abdominal segments brown.

Discussion: This species is closely related to dark specimens ofA. marginalis
Walker, but it differs in having a blackish midtibia, larger body and tricolored
wing, while lacking a white band on tergite 3.

Etymology: the specific name is a tribute to Dr. Graham Bell Fairchild,
rcsearchcr on Neotropical tabanids.

Variations: the male collccted in Mato Grosso is paler. The rl cell some-
times may be entirely infuscated.

Discussion: this species is closely related to A. marginalis Walker, but it
differs by frontal callus narrower than frons, notopleuron and katatergite with
yellowish gray pollcn, yellow hairs dorsally on katepisternum and katatergite.

Etymology: the specific namc is a tribute to Dr. Inocéncio de Sousa Gorayeb,
rescarcher on Amazonian tabanids.
