(type species mygdon).
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.
male abdomen, the eighth sternite is anteriorly cleft and posteriorly slightly
bilobed, a feature seen in the majority of the Parallelia
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.
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.
genus is found throughout the Old World tropics. There are a few rather
localised species in central Indonesia such as emathion
from Sulawesi and imminua Snellen
