Holcocerus chloratoides Holloway sp. n.

♂17mm, ?♀ 19mm. 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 palerspot 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.
