Pomasia lacunaria Holloway sp. n.
♂♀ 8mm. The male has well developed translucent patches at the posterior angle of the forewing cell. Both sexes have the pale fasciae rather clearly defined, relatively unbroken. The male genitalia have the uncus somewhat broad as in P. lamunin, but the aedeagus vesica is more generally scobinate, without a definite row of spines. The female does not have the neck of the bursa spined except in association with a distal lobe, just basal to the main bulb: the main bulb is generally but unevenly spined.
