Aemona infuscata Devyatkin & Monastyrskii, 2008 stat. rev.

( Figs. 11A, B )

Aemona infiscata Devyatkin & Monastyrskii, 2008 was originally described as a subspecies of A. tonkinensis Rothschild, 1916 . The status of the latter taxon was established by Devyatkin & Monastyrskii (2008) showing that A. amathusia (Hewitson, 1868) and A. tonkinensis are separate species. Aemona infuscata is smaller than A. tonkinensis . The hindwings are ochreous brown and darker than the forewings with faint submarginal lunules. The original description does not describe genitalia. However, since the description of infuscata , we have been able to examine the genitalia of many specimens and find that the phallus has a conspicuous, sclerotised rib, the centre of which bears a few spines ( Figure 11A, B ). In A. infuscata , only the distal margin of the clasper’s tip is covered by spines, while in A. tonkinensis spines cover around half of tip. This difference, in concert with differences in size and wing colouration demonstrate that infuscata should be elevated to the species level.
