Psilochira Toxopeus
Type species: lineata Walker.
Synonym: Imaida Toxopeus (type species sinuata Toxopeus = lineata).
The facies is similar to that of Imaus as discussed above. The
hindwing, however, is only marked submarginally by a series of small dashes.
In the male genitalia the uncus is distinctly bifid, the processes
slender. The valve has a slender arm from the base of the costa, and also
narrows to a digitate apex. The sacculus has a patch of coarse spines at its
inner angle. The aedeagus is more robust than that of Imaus, with an
accessory sclerite extending out from the distal side of the junction with the
ductus ejaculatorius.
The female (amydra Collenette) has the eighth segment expanded,
though without ornamentation and with short apodemes. There is a broad ostial
pouch that opens directly into a spherical bursa, wherein there is a large
signum consisting of an irregularly ovate plate with a transverse flange
centrally.
The genus consists of those described below and an undescribed species
represented only by females from Sulawesi mentioned by Collenette (1947). A
single worn male from Seram (slide 1881) taken by the author may be this
Sulawesi species.
