10mm, 9mm. The facies is more or less as in E. dissimilis Moore
(Indian Subregion) and E. verisimilis Prout (Sumbawa), with irregular,
diffuse reddish fasciation on rather deep yellow, the postmedial being more
intense than the rest: the forewing costa is also red, this diffusing away
posteriorly. The main difference is in the male genitalia where the dentate
process of the valve costa (or processes; a feature of subgenus Bardanes) is
large, central, asymmetric (directed distad). There are two narrow central
processes in dissimilis and a row of several that increase in size distad
in verisimilis. The aedeagus vesica has two long, robust cornuti: these
are more slender in dissimilis, and verisimilis has a long row of
much smaller ones. Whilst the ornamentation of the bursa is more or less typical
of Bardanes in the new species, it is reduced in dissimilis, very
basal only, the main signum being absent and the accessory spines small. A
female from Penang (slide 18774) has a slightly different shape to the signum
and strengthening of the accessory spines, but is much closer to sundasimilis
than to dissimilis.
