Tasta acornutata Holloway sp. n.
♂♂ 12-13mm. In facies the species resembles reflexoides, but with the forewing post- and antemedials more distinct. In the genitalia the valves are rather narrow rectangular, with three major digitate processes at about two thirds and further minor ones just distally from these and more basally at about one third where the sclerotised band begins to traverse the valve towards the transtilla. The vinculum is somewhat ‘Y’ shaped as in micaceata but with the structure relatively broader over the ‘stalk’ and ‘arms’ and less deeply cleft. The aedeagus lacks cornuti in the vesica, but has a diverticulum that is slightly more sclerotised and convolute at the apex as in micaceata but not so well developed.
