Description: Body length 6 mm; wing 4 mm. Head and abdomen black, thorax black. Palpus dark brown except for white outer face. Clypeus brown with sparse pale microsetulae. First flagellomere dark brown. 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 brown, white on basal quarter and with a small angled preapical white ring. Tergites black. Oviscape black.

Head: First flagellomere covered by pale microsetulae. Frontal vitta with a darkened spot anterior to ocellar plate. Frontal vitta flat, not swollen anterior to ocellar plate. Epicephala converging, not immediately merging posterior to ocellar plate ( Fig. 6View FIGURES 6–9). Epicephalon somewhat swollen above frontal vitta level.

Thorax: Mesonotum with lines of thin brownish microsetulae. Anterior half of postpronotal lobe bare. Femora covered with sparse black microsetulae. Mid and hind tibia almost cylindrical, sulcus on outer face weak. Female cervical sclerite with a whitish oval swelling, male cervical sclerite smooth. Cell r 4+5 open at the tip of the wing.

Abdomen: Pleural membrane greyish with a white vertical stripe on P3. Female abdomen: Single spermathecal duct apically swollen. Single spermatheca cylindrical, with sparse small rounded finger-like processes ( Fig. 7View FIGURES 6–9). Paired spermathecal duct uniformly thick. Paired spermathecal duct stems tapered on apical third, followed by a disc-shaped swelling and a broader apical half. Paired spermathecae oval and with an apical nipple-like swelling, invaginated apically. Male abdomen: Copulatory fork with small inner basal lobes, less than half as long as the arms. Ejaculatory apodeme smaller than epandrium and with a very small blade, length subequal to 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 ( Fig. 9View FIGURES 6–9).

Comments: P. albibasis  is recognized by the somewhat elevated black epicephalon that contrasts with the brownish and deep frontal vitta. The convergence of the epicephalon plates (not immediately merging) posterior to the ocellar plate and the single spermatheca with sparse small rounded finger-like processes ( Fig. 7View FIGURES 6–9) are also characteristic for the species. Our material from Brazil was limited but we have seen no verifiable specimens of this species from this country, and we suspect that records of P. albibasis  from Brazil noted by Hennig (1934), and repeated by Steyskal (1968) and Ferro & Carvalho (2014) are misidentifications.

Cresson (1926) described Taeniaptera parens  as a new species, even though he recognized that it was probably a junior synonym of Grallomya albibasis  , because he couldn’t verify the number of dorsocentral setae in G. albibasis  . Since the type specimen of G. albibasis  has two dorsocentral setae as in described for T. parens  , and no other characters suggest that these species are different, T. parens  is treated as a junior synonym of P. albibasis  .
