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
(
