Tephriopis Hampson
Type
species: divulsa Walker, Bangladesh
The
forewing facies of this monobasic genus includes the same darker elements as in
the Bessacta group of Anoba (see above), but
these are unbroken rather than archipelagic. The male antennae are biserrate as
in A. rigida rather than
bipectinate as in A. pectinata. The labial palps are longer and more slender than
in other Bornean Anobini, particularly the third segment which is more than
half the length of the second rather than very much less than half.
The
male genitalia have slender socii from the tegumen flanking the uncus. The
valves are relatively short and deep, the costal and saccular thickened
sections overlapping centrally. The aedeagus vesica has sclerites and
scobination but no prominent cornuti or bundles of spines.
In the
female the ductus bursae is long and narrow, the corpus bursae centrally
constricted, and scobinate rather than spined.
The
biology of the only species is described below.
