species : fortissima Moore, N.E. Himalaya.
all large, with striking green and brown forewings with a contrasted pattern
that involves expansion of the reniform and orbicular to form the arms of a pale
central 'V'. This feature is also seen in many species of the next few genera
and others such as Euplexia Stephens and Trachea Ochsenheimer (the
latter is known from Peninsular Malaysia (Yoshimoto, 1987a)). In Checupa the
apex of the male abdomen is enclosed by lateral tufts of hair-like scales, and
the male genitalia provide a number of diagnostic features: the uncus is
apically cup-like, the rim of the cup surrounded by setae; the cucullus is
slender throughout, with one of the coronal setae enlarged into a large spine,
massive in some species; the costal process on the valve is set distal to
the rather dorsally placed, spine-like harpe, below which, from the ventral
margin of the costa, arises a row of long, blade-like setae; the aedeagus vesica
is long, with a terminal group of large cornuti and a band of very
much smaller ones running longitudinally over the finely scobinate zone just
basal to it. The abdomen has a pair of coremata on sternite 8, smaller, well
separated ones on tergite 7, and small lateral tufts of scales on the distal
margins of tergites 3 and 5. The basal trifine
hair pencils are well developed.
In the female genitalia there is a
strong appendix bursae, and the bursa contains four long, fine, scobinate bands;
typical trifine signa. The ovipositor lobes are cashew nut-shaped.
