Chalciope Hübner

Type species: mygdon Cramer, type locality stated as Surinam, probably in error, (Nye, 1975).

Synonym: Euclidisema Hampson (type species mygdon).

The facies is similar to that of Trigonodes Guenée but distinguished by features described under that genus. The forewings are generally somewhat narrower than in Trigonodes, and the species are generally smaller.

In the male abdomen, the eighth sternite is anteriorly cleft and posteriorly slightly bilobed, a feature seen in the majority of the
Parallelia group. The male genitalia also show more affinities with the Parallelia group than with Trigonodes, having a rounded valve with a single corema and an array of three processes fused across the base of the valve from the costa to the sacculus. These show bilateral asymmetry. The uncus has an apical spine and is accompanied by a scaphium. The juxta is of the ophiusine type, but rather broad, H-shaped. The aedeagus is rather broad, as in the vesica, which is highly convolute, though the diverticula are short.

In the female, the ostium is very broad and complex, embedded in the position of the seventh sternite. The corpus bursae arises directly from it and is scobinate in places; there is a small, coiled appendix bursae laterally that gives rise to the ductus seminalis.

The genus is found throughout the Old World tropics. There are a few rather localised species in central Indonesia such as
emathion Snellen and bisinuata Snellen from Sulawesi and imminua Snellen from Wetar.
