Micronia leptaliata Guenée,
1857, Hist. nat. Insectes, Spec. Gen. Lep., 10: 28.
Micronia vagata Moore, 1877, Proc. zool. Soc. Lond., 1877:
622, syn. n.
Diagnosis. This species is smaller than rectinervata with a more acute
hindwing angle. The hindwing has broader bands of striae such that the most
distal white band seen in rectinervata is obscured or very much reduced.
The male genitalia have only a single digitate process on the valve costa, and
the dorsal lobes of the juxta are reduced, the lateral ones absent.
Taxonomic notes. The holotype of vagata has lost its abdomen, so the above
synonymy is based on facies only. There is a complex of species of similar size
but with genitalia more as in the first two species (double costal process,
fully lobed juxta) that includes A. munda Warren (Larat), A. teriadata
Guenée (New Guinea) and a mainland Asian species (e.g. slide 255) that
has been attributed to sparsaria Walker. The original description of sparsaria
refers to a species like Micronia aculeata rather than to an Acropteris,
though the specimen labelled as type of sparsaria in The Natural
History Museum is of this other species: the label states 'E. Ind' rather
than Hindostan as in the description of sparsaria.
Geographical range. N.E. Himalaya, Taiwan (slide 250), Andamans (vagata),
Habitat preference. No recent material has been taken. Older material is
from lowland localities.
