Type species, Schizomyia galiorum Kieffer, 1889 (by monotipy). Generic placement and diagnosis. Schizomyia is considered a ‘catch-all’ genus for species of the supertribe Schizomyiina ( GAGNÉ, 1994 ; GAGNÉ & JASCHHOF, 2017 ). Recently, ELSAYED et al. (2018) proposed that Schizomyia can be distinguished from the other genera of Schizomyiina by the following combination of characters: palpi four-segmented and ovipositor protrusible, with needlelike protrusible portion ( GAGNÉ, 1994 ; GAGNÉ & MENJIVAR, 2008 ), tarsomeres I without ventroapical extension, except S. maricaensis Sousa & Maia ( SOUSA & MAIA , 2007) and S. novoguineensis Kolesik ( KOLESIK &BUTTERILL, 2015 ), and larva usually with bilobed spatula and eight or fewer terminal papillae. KOLESIK & BUTTERILL (2015) discussed the variation of the number and shape of papillae in the larval terminal segment among the Schizomyia species, ranging from four setose pairs to a single corniform pair, and the absence or presence of cercilike (dorsobasal) lobes in the ovipositor. Additionally, it was observed that the male gonocoxite of the Neotropical species is oblong instead as almost rectangular in non-Neotropical species of Schizomyia ( Fig. 7 ).
