Teulisna pseudochiloides sp. n. 


Teulisna pseudochiloides (paratype)
(x 1.30)


, 12-13mm. This species is similar in facies to chiloides but is less yellow, more fawn, with more brownish clouding over the forewing and marginally on the hindwing. The forewing lacks the central subcostal comma-shaped mark, but has a more prominent brown lunule on the costa subbasally. The single female seen is generally darker than the male and has the forewing bisected longitudinally by a dark brown streak. The male genitalia differ markedly from those of chiloides, resembling more those of taxa with transverse black bands on the forewing. There is a paddle-like costal process to the valve and an evenly curved saccular process that is unusually robust and apically rugose. The aedeagus vesica lacks cornuti.
