Lophoptera punctapex Holloway comb. & stat. n.  
Stictoptera ekeikei punctapex Holloway, 1976: 19.

Lophoptera punctapex

Lophoptera punctapex

The narrow forewings are a dark, slightly brownish indigo; there is a subapical yellow spot associated with the weak, whitish, broken submarginal. The second form illustrated, with a sinuous grey basal cloud that extends to include the reniform, is less common than the immaculate form, comprising perhaps 20% of specimens taken on the Mulu survey.

Taxonomic notes. The species has typical Lophoptera characters and is therefore transferred to that genus from Stictoptera It shares with the next two species the narrow, Gyrtona-like forewings and characters of the male genitalia described in the generic introduction.

The species is here treated as distinct from L. ekeikei Bethune-Baker comb. n. (New Guinea), a larger species without a grey-clouded form or a yellow subapical spot, and a broader, dorsally obtusely angled costal process to the valve and a shorter, broader uncus in the male genitalia. The next species is obviously more closely related to punctapex than is ekeikei, though the latter falls within the same species group of the genus.

Geographical range. Borneo, Sumatra.

Habitat preference. The holotype was taken at 1200m on G. Kinabalu in the same locality as L. olivascens. During the Mulu survey the species was encountered frequently in the lower and upper montane forest of G. Mulu, the lowland and lower montane samples on G. Api, and singly in the kerangas sample.
