arising on discal cell, cross-vein r–m present; wing straight, not bent over abdomen; face flat; male eyes contiguous medially; eye not pilose; postocular ridge carinate in female, male narrowly carinate; antenna greatly elongate, scape much shorter than flagellum; flagellum cylindrical, circular sensory pits on flagellomeres I–III, flagellomeres IV–V very short and of similar length, flagellomeres VI–VII longer and of similar length; flagellomere VIII longer than all other flagellomeres, usually covered with deeply plumose microtrichia; abdomen ovoid in both sexes.
Comments
.
Eudmeta
contains three species (
Woodley 2001
;
Yang
et al
. 2010
) and is differentiated from other clitellariine genera in these regions by the following characters: absence of a nose-like process on the face, absence of scutellar spines (shared with
Lagenosoma
and
Ruba
) and notopleural spines, wings straight (bent over abdomen in
Octarthria
).
Examination of specimens of the relatively recently described
Eudmeta coerulemaculata
Yang Wei
et
Yang, 2010
, indicate that it is a synonym of the widely distributed
E. marginata
and that differences between the two species outlined by
Yang
et al.
(2010)
are colour differences attributable to variation in preservation condition and age of specimens; live specimens of both species appear identical. Comparisons of morphology of the male genitalia of both species also supports that they are the same species. In
E. marginata
and
E.
coerulemaculata
(see
Yang
et al
. 2014
: fig. 181) the gonostylus is similarly forked with one arm shorter than the other, while in, for example
E. diadematipennis
, the gonostylus is not forked (see
Yang
et al
. 2014
: fig. 182). Two
Eudmeta
species
are endemic to
India
, while
E. marginata
is widely distributed throughout Southeast Asia, including southern
China
,
India
and extending as far east as central
Indonesia
.
