Perixera javensis Warren stat. rev.
   
Conchocometa javensis Warren, 1897, Novit. zool., 4: 216.


Perixera javensis


Diagnosis. See Perixera decretarioides sp. n.

Taxonomic notes. This species is genitalically distinct from decretaria Walker and sympatric with it, hence must be taken out of synonymy with it. P. pallida Moore stat. rev. & comb. n. (Sri Lanka) also has male genitalia strikingly different from those of decretaria. P. irregularis Warren from New Guinea has male genitalia with features as in this group: it is the type species of Plocucha Warren. The taxon Anisodes contractata Walker (Sarawak) resembles javensis but is currently regarded as a synonym of the mainland Asian P. obrinaria Guenťe. The latter is not otherwise known from Borneo. The type of contractata lacks an abdomen, hence its status is unclear.

Geographical range. Java, Borneo, Singapore, Bali, Sumbawa.

Habitat preference. Three Bornean specimens have been examined, all from Sarawak: from Kuching in the lowlands; from 300m (lower montane forest) on the limestone G. Api; from G. Murud, with no altitude recorded.
