Boradiopsis cheyi Holloway sp. n.
♂ 10mm.
This is the smallest species, with rather narrow, apically produced forewings where the dark markings are slightly reduced and more irregular in distribution, with the postmedial broadening to the dorsum. The hindwing border is very narrow, tapering away completely at the centre of the distal margin. The male abdomen has the eighth segment similar to that of aequalis except the concave margin of the sternite is not rugose and the spines flanking it are less curved, slightly more robust. The genitalia have the uncus more narrowly bilobed. The dorsal valve processes are shorter and broader than in aequalis and are apically spatulate. The ventral processes are more rectangular. There is only a very shallow saccus. The aedeagus is slender, sinuous, lacking a hump, but having its apex very long and tapering to a point.
