Arachnognatha
Hampson
Type
species: meterythra
Hampson, Burma.
This genus resembles in facies a more delicate version of
Plotheia
Walker species, but otherwise has features as in the more careine group
of genera in the Ariolicini with somewhat careine male genitalia. The venation
is unusual with the areole long and veins R2 to R5 all arising directly from it.
The hindwing cell is short, indented between M1 and M2, but with no stalking or
loss of veins distal to it.
The male abdomen lacks tymbal structures but has narrow apodemes on the eighth
segment, long on the tergite, very short on the sternite. The genitalia are of
the careine type, the valves with a slender subbasal costal process extending
distally adjacent to the valve margin. The gnathus and subscaphium are well
developed as in Labanda and allies. The aedeagus vesica lacks cornuti.
The female has a very short ductus with a colliculum and a flimsy, elongate
bursa almost three times as broad as the ductus.
Both included species are Oriental as discussed below.
