Image of Perixera punctata Holloway ♂ (holotype, ssp. calciphila ) — ♂ (holotype, ssp. calciphila )

Perixera punctata Holloway comb. n.ssp. n.

Pisoraca punctata Warren, 1897, Novit. zool., 4: 22.

Anisodes punctata interpolis Prout, 1938, Gross-Schmett. Erde, 12: 166.

♂♀ 11-13mm. Distinction from other Bornean species is made under P. confiniscripta. The hindwing discal circle is twice as large as in any other subspecies, resembling that of P.insitiva Prout comb. n. (S. India), possibly another race of punctata (though the holotype male has not been located, the remaining specimens being female). The punctate black markings of the wings, particularly those on vein M2 postmedially and along the margins, are much more emphatic than in the other taxa. In the male genitalia the processes of the valve are more slender than in typical punctataand turn down well before the valve apex (longer than in punctata) rather than beyond it.

Taxonomic notes

There are no coremata in the male abdomen, and the genitalia are unusual. Though the uncus is vestigial, the valve has ornamentation atypical of Perixera. There are two downturned processes, a setose one from the costa and a more sclerotised one without setae arising from the centre of the valve lamina. Hong Kong males have hindwing discal spots and male genitalia as in Bornean ones.
