Yashmakia
orsinephes Prout comb. n.
Synegia orsinephes Prout,
1928, Bull. Hill Mus., Witley, 2: 56.
Diagnosis. The almost circular rippled grey patch just distad from the forewing
discal spot distinguishes this species from congeners and others in related
genera.
Taxonomic notes. The angulation of the wings and the transversely linear forewing discal
spot are as in Yashmakia, as is the ornamentation of the aedeagus vesica.
The valve, however, has an elongate corema, two costal processes and a very much
more basal peg seta. The uncus base is narrow. On balance, combination with Yashmakia
rather than Parasynegia seems preferable.
Geographical range. Sumatra, Borneo.
Habitat preference. Two Bornean specimens are from lowland alluvial or
swampy forest, one is from lower montane forest (G. Mulu) and one from upper
montane forest (Bukit Retak, 1618m).
