Condate
rectiorsilla sp. n.
 ,  13-14mm. This species is slightly larger and darker than orsilla,
but with similar fine, pale fasciae. However, the costal loop of the forewing
postmedial is somewhat longer because the posterior part of the fascia runs
straighter to the subcostal flexure. The antemedial is straight, rather than
curved as in orsilla,
resembling the illustration of snelleni Semper. However, the submarginal is more prominently
paler than in orsilla and more angled than in snelleni,
particularly at one quarter from the dorsum. The male genitalia have the valves
apically acute rather than rectangular, with the costal margin slightly concave
and the ventral margin strongly curved. The saccular process is small and lacks
a process dorsal to it (present and angled in orsilla).

Taxonomic
note. Yoshimoto (1998) recorded a species he identified as C.
orsilla from
the Ryukyu Is. The illustrations of facies and male genitalia indicate that it
is probably rectiorsilla,
hence the geographical range may well be wider than that given below.
Geographical
range. Borneo, ?Ryukyu Is.
Habitat
preference. All specimens from the Mulu survey except one specimen are
associated with limestone, the holotype being from the highest altitude in upper
montane forest on G. Mulu. The other two specimens are from the lowlands.
