Taxonomic notes. This species was described based on a single male, no further specimens are known. It shows a special mixture of characters. The dark “smoky” general colouration has some similarity with X. argyrogramma, but all markings are obsolescent. The extremely elongate shape of forewings and the faint maculation is similar to X. xenogramma, but without the longitudinal “wash” (Plate 5, Fig. 29). Male genitalia are also rather similar to that of X. xenogramma (figured in Varga 1985: 30, fig 4a) but the bilateral lobes of tegumen are more elongate, costal extension of valva dentate, digitus more spatulate, juxta with acute dorsal extension. It is possible that these differences represent only extreme variations of X. xenogramma but this cannot be resolved at present since the female is unknown and no recent material has been available.
