has not proved possible to assign one amphipyrine species to genus. Euplexia
monilis Moore is a species with typically plesiomorphic amphipyrine forewing
patterning, though in an unusual pale green with a pale reniform conspicuous.
The male antennae are ciliate, and the hindwing has vein M2 present but weak as
in a few other Amphipyrini genera as mentioned on above.
In the male abdomen there are no trifine hair pencils, but lateral rods are
present on the eighth sternite. In the genitalia the peniculus is strongly
lobed, the valve is unusually bifid at the apex, and the harpe is very large,
sinuous, separated by a small lacuna from the main part of the sacculus. The
aedeagus vesica has a major secondary diverticulum, itself with a subbasal lobe
and a series of small bulges in a scobinate zone towards the apex.
The species 'Hypoperigea' turpis Walker (Himalaya) is somewhat similar in
facies (though pale brown) and some features of the male genitalia such as a
triangular valve apex and a strong harpe that may indicate a relationship with monilis.
This does not allow a tentative generic placement as turpis is
misplaced in Hypoperigea Hampson (type species tonsa Guenee,
Australia; See Holloway, 1979).
