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 Author László, Gyula M. Author Ronkay, Gábor Author Ronkay, László text Zootaxa 2015 4048 2 232 250 journal article 10.11646/zootaxa.4048.2.5 e4badffa-b02e-4e21-82c1-cf046bd1822a 1175-5326 240651 D00430CF-A1D7-4B71-B230-35FC80D3AE71 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 ) Ctenane labuana ( Swinhoe, 1904 ) (Plate 3, figs 1–4; gen. figs 13–16) Agrophila labuana Swinhoe, 1904 , Transactions of the Entomological Society of London. 1904 : 139.
