Polypogon decipiens: Holloway, 2008: 130–131, part, figs 304, 312, pl. 6, fig. 14, nec Hampson, 1898

Type material. Holotype ♀, Borneo, Sabah, Mts. Crocker, 16 miles NW of Keningau, 1,400 m, 4. IX. 1982, NSMT3083 ♀, S. Nagai leg., in NSMT . Paratypes. Borneo, Saba, Mt. Kinabalu, Park H. Q., 1,560 m, 1♀, 8–18. XI. 1979 , NSMT3121 ♀, T. Hasegawa leg., in NSMT; same locality, 1,620 m, 1♂, VII–IX. 1965, Cambridge Expedition to Mt. Kinabalu, 1965, H. J. Banks, H. S. Barlow & J. D. Holloway leg., in NHMUK; Borneo, Sarawak, Gunong Mulu Nat. Park, Site 3, Camp 4, montane forest, 1,780 m, 453463, 1♀, I. 1978 , R.G.S. Expedition, 1977-8, J. D. Holloway et al. leg., in NHMUK. Dr J. D. Holloway kindly informed us detailed collection data of the Bornean pair, which were recorded in “Moths of Borneo”, and their genitalia were illustrated by Holloway (2008, figs 304♀, 312♂) .

Diagnosis and notes. In Moths of Borneo, Holloway (2008) described the wing maculation of “ Polypogon decipiens ” based on the holotype of H. decipiens from Khasi Hills, India, because Bornean specimens were too worn. He also described the male labial palpus, but did not state on which specimens from Borneo or Khasi Hills was based. The description of the male genitalia in the present study is based on the illustrations and descriptions by Holloway (2008), and it is obvious that the large coecum penis of Bornean male is similar to that of Himalayan H. yuksam, and different from smaller coecums of H. decipiens, H. terminalis and H. amamioshima . In the female genitalia, the papillae anales and 8th segment are slenderer than the other species of the H. decipiens complex, and the joint part of ductus and cervix bursae is different from those of the others.

Description. Female (Fig. 20). Expanse 27 mm, length of forewing 14 mm. Male genitalia (Holloway, 2008, p. 131, fig. 312). Uncus long, slender. Valva of Herminia type with slender, straight costal process, though this is very long, tapering acute, extending just beyond the valve apex. Coecum penis large. Aedeagus vesica (not everted) with a few large cornuti basally, more general finer scobination distally. Female genitalia (Fig. 44; see also Holloway, 2008, fig, 304). Papillae anales and 8th segment somewhat slender. Ductus bursae rather straight, ostium moderate, more delated anteriorly, sclerotized portion largest at junction of ductus and cervix bursae. Corpus bursae as in the others.

Distribution. Borneo.
