 Oonionota incalescens (Meyrick), Clarke, 1963, Catalogue of the type specimens 



of Microlepidoptera in the British Museum (Natural History) described by 



Edward Meyrick, vol. 4, p. 237, pi. 115, figs. 1-16. 



Meyrick described this species from two males, the only two known. 

 Although the basal patch of forewing is greatly reduced, incalescens 

 unquestionably belongs in this group. The small basal patch, the con- 

 spicuous white, triangular costal spot, and the genitalia at once 

 distinguish incalescens from melobaphes.
