Roeselia trianguloquelinea

László, Gyula M., Ronkay, Gábor & Ronkay, László, 2015, On the taxonomy of the genera Proneca Swinhoe, 1890, Ctenane Swinhoe, 1905 and Selca Walker, 1866 (Lepidoptera, Nolidae, Nolinae), with the description of two new species from Sumatra, Zootaxa 4048 (2), pp. 232-250 : 242

The trianguloquelinea species-group

Diagnosis. Externally very characteristic species with whitish forewings ornamented with conspicuous blackish, evenly arcuate postmedial line. The two species are externally confusingly similar, the proper identification requires the study of the genitalia which show easily recognisable specific differences in both sexes.

The diagnostic features in the male genitalia are the narrow, medially tapered valva, the bifid or dentate harpe arising on the ventral margin of valva, being rather remote from the valval base, and the long, straight apical carinal process. The members of this species-group have small, fine scobinate section in the vesica; this is the only differential genital character between the two species-groups of Ctenane as the species of the labuana group lack this scobination.

In the female genitalia, the typical character is the single, long, finger-like process of signum bursae.

Distribution. The range of this species-group is partly overlapping with that of the labuana -group in the Sundaland, but it is considerably larger, extending also to the continental SE Asia (Indochina, SE China and Taiwan).
