Taeniaptera teresacristinae Albuquerque, 1981: 831.
Paragrallomyia teresacristinae (Albuquerque), Jackson et al. 2015: 14.
Description: Body length 7 mm; wing 5 mm. Head and abdomen dark brown, thorax black. Palpus yellowish brown except for white outer face. Clypeus brown with sparse pale microsetulae. First flagellomere brown. Frontal vitta with a large tear drop like black velvety spot anterior to ocellar plate (Fig. 47). Fronto-orbital plate dark brown. Row of katepisternal setae brownish. Fore tibia dark brown. Fore tarsus mostly white, tarsomere one brown on basal half only. Hind femur mostly dark brown, white on basal quarter and with a small angled preapical white ring. Tergites dark brown. Oviscape dark brown.
Head: First flagellomere covered by pale microsetulae. 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: Mesonotum with lines of thin brownish microsetulae. Anterior half of postpronotal lobe bare. Femur covered with sparse brownish microsetulae. Mid and hind tibia cylindrical, without sulcus on outer face. Female cervical sclerite brown and smooth, without swelling on posterior end. Cell r 4+5 open at the tip of the wing.
Abdomen: Single spermathecal duct apically swollen. Single spermatheca smooth, cylindrical and elongated, length more than half as single spermathecal duct. Paired spermathecal duct with a rounded swelling before splitting into stems. Paired spermathecal duct stems tapered basally, gradually swollen on apical half ending with a large rounded swelling, about same size as paired spermatheca (Fig. 48). Paired spermathecae oval and striate, invaginated apically only. Male abdomen (Albuquerque 1981: 833): Ejaculatory apodeme bigger than epandrium and with a broad 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 teresacristinae: BRAZIL. Amazonas. Manaus. Reserva Florestal Ducke. 26.IV.1968. L. P. Albuquerque coll. (1 ♂, INPA).
Material examined: BRAZIL. Amazonas, Rio Negro, downstream Uaupes, last right tributary of Rio Curicunari, 5.III.1994, M. von Tschirnhaus coll. (1 ♀, DEBU00280345).
Distribution: Brazil.
Comments: An easily distinguished species due to the black teardrop-like spot anterior to the ocellar plate, contrasting with a light brown and somewhat elevated epicephalon.
