Diagnosis. This species and Collix intrepida Prout are similar in external
appearance, resembling rather pale brown Collix species but lacking the
prominent, raised forewing discal spot. P. hyperythra is smaller, with
less angled forewing postmedials, more prominent discal spots and, on the
underside, strong black markings, particularly the discal spots and postmedials:
these last are not seen in intrepida.
Taxonomic notes. There is some variation in the form of the saccular processes of the
valve through the range of the species: in Bornean males these are particularly
broad on the left valve and long on the right, the genitalia being generally
relatively robust. There is also variation in the breadth of the funnel- like
Geographical range. Sri Lanka, India to Taiwan (ssp. catalalia) and
Japan (incl. Ryukyu Is.), Burma, Borneo, Java, Luzon, Sulawesi.
Habitat preference. So far only known from G. Kinabalu, the species is
infrequent from 1760m to 2110m.
