Pleurona Walker
Type
species: falcata Walker.
The
facies of the type species is described below. The male antennae are
fasciculate, but the legs are not strongly modified. The labial palps have the
second segment long, but the third is very short.
The male
abdomen has a frame and small lateral rods to the eighth sternite and
pincer-like apodemes on the tergite, but these sclerites are less strongly
modified than in the previous genus or the next one. The genitalia have narrow,
tapering valves, but these lack external coremata. There is a small lobe marking
the end of the sacculus on the ventral margin at one third. There appears to be
paratergal sclerites at the junction of the tegumen with the vinculum. The
aedeagus vesica is similar to that of Poliofoca
but
less heavily scobinate.
The
female has ovipositor lobes similar to those of the Episparis
group
and some slight scobination around the ovipore. The ostium is between the
seventh and eighth segments, the sternite of the former being slightly reduced.
The ductus is moderate, slightly tapering, unsclerotised. The corpus bursae is
pyriform, without ornamentation.
The
biology of the type species is described below. The genus also includes P.
ochrolutea Hulstaert
from the Kei Is. and P. sirenia Viette from Madagascar (Poole, 1989).
