Agrophila labuana

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 : 239

The labuana species-group

Diagnosis. The splitting of Ctenane into species-groups is based on the very characteristic habitus of the two distinct lineages: the two species belonging to the labuana group have similar external characters expressed by the pale greyish forewing ground colour, the conspicuous, relatively broad, dark brownish or blackish stripe in the median area of forewing, and the fine but conspicuous row of blackish dots replacing the postmedial line. The general configuration of the genitalia of both sexes is very similar in the two species-groups (the labuana and the trianguloquelinea species-groups), sharing the generic autapomorphies which are mentioned in detail under the diagnosis of the latter species-group.

The formerly known two species of the lineage are considered here as conspecific due to their identical genitalia features; a second species is discovered in Sumatra which is described below.

Distribution. The known range of the species-group is the north-western part of the Sundaland (Borneo, Sumatra and the Philippines)
