Diagnosis. This and Perixera clandestine
Prout comb. n. are very similar and can only reliably be
distinguished from the genitalia. This species has a narrower angled valve in
the male, compared with a quadrate one. In the female the ductus bursae is
longer, the bursa asymmetrical. The setose area of the terminal segments is less
extensive. On the hindwing, the discal mark is more heavily ringed with dark
brown in the next species, which is also slightly smaller.
Taxonomic notes. The similarity of the male genitalia of niveopuncta and paucinotata
was noted by Holloway (1982), but no formal synonymy was made. There is
probably no justification in treating the taxa as distinct, and the Oriental
range of the species is being extended by further observations (Inoue, 1994; A.
Galsworthy, pers. comm.).
Geographical range. Queensland, New Guinea, New Caledonia, Vanuatu, Fiji,
Tuvalu, Kiribati, Society Is., Tuamotus, Henderson I., Sulawesi, Borneo,
Peninsular Malaysia, Nias, Ogasawara (Bonin) Is. Hong Kong.
Habitat preference. No material has been taken in recent surveys, but
older specimens are from the lowlands.
