Cossus chloratoides sp. n.
This species is similar to chloratus in forewing facies but a more
reddish brown colour with finer, less definite striae and a slightly darker
medial block. The putative female is. reddish brown basal to the sharply defined
postmedial and paler narrowly distal to it; there is a paler spot with a darker zone just adjacent distally at the disc. In chloratus
and javanus the female forewing is extensively blackened basal to the
postmedial and there is a pale patch at one third on the costa. The male
genitalia have a diagnostic semicircular flange subapically on the valve. The
male antennae are filiform rather than uniserrate/pectinate.
