Pseudotephritina
Pseudotephritina is a genus of picture-winged flies in the family Ulidiidae, established by Malloch in 1931. The genus contains at least two described species: P. cribellum (Loew, 1873) and P. inaequalis (Malloch, 1931). As members of the Ulidiidae family, these flies possess characteristically patterned wings that serve in species recognition and courtship displays. The genus is distinguished from related ulidiid genera by specific wing venation and body proportions, though detailed biological studies remain limited.
Trixoscelis polita
Trixoscelis polita is a species of small fly in the family Heleomyzidae, subfamily Trixoscelidinae. The species was described by Malloch in 1931. Like other members of the genus Trixoscelis, it is associated with decaying organic matter and fungal habitats. The family Heleomyzidae is part of the muscoid fly radiation within Brachycera, and Trixoscelidinae represents one of the more specialized lineages within this family, often found in distinctive microhabitats.
