Synegiodes obliquifascia Prout, 1918 , Novit. zool. 25: 78. Holotype, India: Cherrapunji, in coll. Tring Museum (now NHM).

Diagnosis. The species is similar to S. diffusifascia and S. expansus externally. They all have yellowish brown wings and brown transverse bands and are hard to distinguish by external means only. A very clear character among the three species is that S. obliquifascia has two areoles in the forewing venation, but S. diffusifascia and S. expansus have only one. Moreover, the wings are narrower and slightly longer and the transverse lines are more strongly inclined in S. obliquifascia . A further good character of S. obliquifascia is the elongated, black marginal patch between M2 and M 3 in the forewing which is round and indistinct in the other two species. More detailed comparisons with S. diffusifascia and S. expansus see under S. expansus .
