( Figs. 29–30 )

Taeniaptera inpai Albuquerque, 1980: 876 .

Paragrallomyia inpai (Albuquerque) , Jackson et al. 2015: 14.

Description: Body length 6 mm; wing 4 mm. Head mostly dark brown, frontal vitta and fronto-orbital plate brown. Thorax and abdomen black. Palpus dark brown except for white outer face. Clypeus dark brown with sparse pale microsetulae. First flagellomere black. Fronto-orbital plate dark brown. Row of katepisternal setae brownish. Fore tibia dark brown. Fore tarsus mostly white, tarsomere one with brownish setulae and brown on basal quarter only. Hind femur mostly dark brown, white on basal fifth and with a small angled preapical white ring. Tergites black. Oviscape black.

Head: First flagellomere covered by pale microsetulae. Frontal vitta with a weak darkened spot anterior to ocellar plate. Frontal vitta flat, not swollen anterior to ocellar plate. Epicephala converging, not immediately merging posterior to ocellar plate. Epicephalon somewhat swollen above frontal vitta level.

Thorax: Anterior half of postpronotal lobe with five strong black setae ( Fig. 29 ). Femur covered with sparse black microsetulae. Mid and hind tibia almost cylindrical, sulcus on outer face weak. Female cervical sclerite brown and with a nipple-like swelling. Cell r 4+5 open at the tip of the wing.

Female abdomen: Single spermathecal duct broad on apical half. Single spermatheca elongated and cylindrical. Paired spermathecal duct conspicuously broad on apical half, tapering only apically before splitting into stems. Paired spermathecal duct stems with a rounded swelling basally, tapering and with an apical large rounded swelling ( Fig. 30 ). Paired spermathecae smooth and cylindrical. Male abdomen (from Albuquerque 1980): Copulatory fork small and without inner basal lobes. Ejaculatory apodeme bigger than epandrium and with a broad blade, blade bigger than sperm pump. Phallapodeme short, not extending to anterior limit of hypandrium. Distiphallus long, longer than epandrium, phallic bulb subequal in length and width. Distal distiphallus short and thin, 1/4 of length and almost half of width of basal distiphallus.

Type material: Holotype of Taeniaptera inpai : BRAZIL. Amazonas. 50 km E of São Gabriel. 20.I.1978. N. D. Penny coll. (1 ♂, INPA).

Material examined: BOLIVIA. La Paz , Heath River, Wildlife Centre, ~ 21 km SSW Puerto Heath, 12º40’S 68º42’W, 29.IV–12. V .2007, S. A. Marshall (1 ♀, CBFC, DEBU00282086 ) .

Distribution: Bolivia, Brazil.

Comments: This species can be easily recognized by the two anterior rows of long black setae on the mesonotum ( Fig. 29 ). The conspicuously broad paired spermathecal duct (broader than the paired spermathecae) is also remarkable.
