Diagnosis and taxonomic notes. C. obstataria and
C. imbuta Warren are smallish rather uniform red species that could be
confused with members of the Trirachopoda section of Perixera
Meyrick but the discal spots lack pale centres, being more transverse
dashes. The male hind-tibia is not shortened and tufted as in that section.
This species can only reliably be distinguished from imbuta by
the male genitalia, a process that led to recognition that imbuta Warren
was distinct. The red ground colour may be a little deeper in imbuta but
this is not fully reliable. In imbuta the valves are more elongate, the
processes flanking the tegumen are larger, more outcurved, the left longer than
the right rather than vice versa. The aedeagus vesica in imbuta has a
long, slender, rather sinuous cornutus.
Holloway (1979: 286) discussed other Australasian and Pacific species in
this group: C. compacta Warren comb. n. (Kei, New Guinea, Queensland); C.
lateritica Holloway comb. n. (New Caledonia): C. lautokensis Prout
comb. n. (Fiji).
Geographical range. Indian Subregion and China to Sundaland, New Guinea
Habitat preference. During the Mulu survey singletons were taken in lower
montane forest at 900m on G. Api and 1000m on G. Mulu.
Biology. The New Caledonian C. lateritica was reared from Codia (Cunoniaceae),
but the Cunoniaceae are largely Australasian (Holloway, 1979).
