Paragrallomyia and Taeniaptera couplet, starting at “14” in Marshall’s (2010: 809) “ Taeniaptera Macquart” lead 14’) Wing membrane around anterior part of dm-cu almost always unpigmented (Figs. 1, 6); if pigmented (Paragrallomyia brasiliensis) then cell r 4+5 open at the wing margin. Cell r 4+5 rarely closed (closed only in the Central American species P. vulpes). Distal distiphallus narrow, basal distiphallus twice as wide as distal distiphallus and membranous (Figs. 5, 9, 23, 34, 38, 42, 46, 52, 56)............................................................................ Paragrallomyia Hendel - Wing membrane around dm-cu completely pigmented and cell r 4+5 always closed at the wing margin (Fig. 2). Distal distiphallus as wide as basal distiphallus and heavily sclerotized (Fig. 2).................................. Taeniaptera Macquart
