Abstract
The genus Callithrinca includes only two species, belonging to the tropical region, viz., C. evocatella (WALKER) from Borneo and C. niphopyrrha MEYRICK from Fiji. In the present paper, a new species is added to the genus. It is described from a male specimen taken by me during the expedition to collect lepidopterous insects in Thailand in 1981. I take this opportunity of redescribing the genus Callithrinca. I wish to express my thanks to Professor H. KUROKO, the leader of the expedition, for his active interest. I am also indebted to Dr T. WONGSIRI, Mr M. RUMAKOM and Dr A. LEWVANICH, of the Thai Department of Agriculture, for their generous help during my stay in Thailand.
