Nyctemera kinabaluensis Reich stat n

Nyctemera arctata kinabaluensis Reich, 1932, Int. ent. Z., 26: 238.

Nyctemera arctata kinabaluensis Reich; Holloway, 1976: 6.

Diagnosis

On the forewing the basal white patch is linked by white along vein CuA2 with the postmedial band. The hindwing border is entire, lobed interiorly in the spaces.

Taxonomic notes

This species has male genitalia very similar to those of diaphana Roepke from Sulawesi and very different from those of typical arctata. Also in the group are browni Schultze (= conjuncta Wileman; Luzon) and hyalina Bethune-Baker (New Guinea, S. Moluccas). In facies the species is closest to browni but lacks the signum in the bursa seen in browni, resembling diaphana more in this respect; the lamella postvaginalis is deeper than in either species.

Geographical range

Borneo.

Habitat preference

The species is frequent from 1000-2000m on G. Kinabalu, but has not been taken elsewhere in Borneo.

Biology

All material was taken at light by night.

Taxonomic Note

N. kinabaluensis forms a group with a number of Philippines species such as browni Schultze, palawanica de Vos & Cerný, angustipennis Kishida, undulata de Vos & Cerný and others in the arctata Walker group as discussed by de Vos & Cerný (1999: 153 et. seq.). They included Borneo in the distribution given for true arctata Walker, but this is an error (R. de Vos pers. comm.). A single specimen of the Taiwan subspecies of arctata, albofasciata Wileman, has been recorded from Luzon, but de Vos & Cerný (1999) raised the possibility that the label data might be incorrect. These species belong to the arctata subgroup; the luzonensis‐subgroup of de Vos & Cerný (1999) contains four montane species endemic to the Philippines but also extends further east to the S. Moluccas.
