Cyana conclusa Walker
Bizone conclusa Walker, 1862, J. Linn. Soc. (Zool.),
and taxonomic note. The
species is similar in facies to the next three (double discal spot in male,
single in female) but can be distinguished by the rather M-shaped postmedial in
both sexes (seen to some extent also in maiae
sp. n.) and the frequently dentate centre to the inner margin of the
black line of the antemedial. The male has an acute angle to the forewing margin
just posterior to the apex. In males, the black delineation of the forewing
fasciae can be weak to absent (e.g. in the holotype). The male genitalia have a
ventral spur to the dorsal part of the valve, seen also in the externally
similar javanica Butler (see Roepke,
[1946a]), from which it is distinguished by a cluster of spines in the aedeagus vesica;
javanica has a single angle to the postmedial. C.
bebas Roesler & Küppers (Sumatra) may be a synonym of javanica
sumatrensis Druce, and C. garuda Roesler
& Küppers (Sumatra) may prove to be merely a lightly marked specimen of conclusa.
species is one of the rarer members of the genus, taken infrequently in a range
of lowland forest types, excluding heath forest. The highest record is from 900m
on the limestone G. Api.
