M. priapus
.
Male: FW venation (Fig. 3) almost similar to
M. elegans
and
M. priapus
, but 1Aa prolonged up to the apical field (compare Figs 1-2). Stridulatory file with 93 (HT) to 102 teeth (PT) (m
=
98, n = 2).
Male genitalia (Figs 4-5): very similar to
M. priapus
laterally except for the lateral edge of pseudepiphallic sclerite, straight and folded ventrally, while it is rounded in

and
M. priapus
