Microselene Hampson
Type
species: mesostipa Hampson, see below.
The
genus has facies features that distinguish it from Margana as discussed
under mopsa Swinhoe below: narrower forewing with a lunulate pale orbicular
on the upperside and a darker crescent on the underside at the anterior
concavity of the distal margin; a straight postmedial to the hindwing. In
common with the previous genus and the next, the second tergite of the abdomen
lacks phragma lobes.
The
male abdomen varies considerably between the type species and mopsa, the eighth
sternite being deeply cleft distally in the former, the tergite narrow, rather
ovate, with strong, unsplayed apodemes; in the latter the segment is virtually
unmodified. In the genitalia, the uncus, tegumen and valves are extremely long
and narrow in mesostipa but with more normal proportions and relatively
simple in mopsa. The aedeagus is small in both species, with one cluster of
small spines in the vesica.
The
female genitalia of the two species are more similar, with only slight pulling
forward of the ostium in the eighth segment, though it is still cleft
posteriorly. There is a pair of small triangular processes flanking the cleft.
The seventh sternite is only moderately reduced rather than vestigial or
absent. The ductus is a short sclerotised tube. The corpus bursae
is spherical with an irregularly transverse band of scobination at one
third.
The genus
contains only the two species discussed here.
