Gaurenoglaea Ronkay, Ronkay, Gyulai & Hacker, 2010 Gaurenoglaea misconspicua Ronkay, Ronkay, Gyulai & Hacker, 2010 Ronkay et al. 2010 b: p. 280; fig. 65; pl. 53, fig. 2. Diagnosis The external appearance of the species in this genus is distinctive within the tribe Xylenini (Figs 1, 2, 3). The ground colour of their forewings is dark brown, with numerous large and small ochreous patches distributed, which makes them most similar to Houlberthosia ornatissima. However, their wingspan is relatively small, the compound eyes are uncovered and their tegulae are dark brown, lacking an ochreous-white colouration. The colour of their abdomens is also distinct. Moreover, the patches on the forewing of Gaurenoglaea species are more ochreous and the hind-wings are brown rather than a glossy milky ochreous colour. Regarding male genitalia (Fig. 4), all three known species of this genus display remarkably similar characteristics: the weak tegumen with well-developed penicular lobes, the large, ribbed-folded clavus and especially the well-developed falcate cucullus and long, arc-shaped harpe, which render them similar to those of Hemiglaea costalis (Butler, 1789) (Fig. 6) and Hemiglaea jumla Hreblay & Ronkay, 1999. However, the juxta of Gaurenoglaea species is narrower and the aedeagus shows significant differences. Their aedeagus shows a well-developed ventral carinal bar and ventro-lateral carinal bar (the ventro-lateral carinal bar is reduced in G. medogensis sp. nov.) and the vesica has nail-shaped or long-spiny terminal cornuti. Based on G. alternata (Fig. 5), the most prominent feature of the female genitalia is the drop-shaped and membranous corpus bursae as well as the double sclerotised process that extends into the basal portion of the appendix bursae. Distribution Species of this genus are known from Vietnam (Lao Cai) and south-western China (Sichuan and south-eastern Xizang Autonomous Region) (Fig. 7). Biology The species of this genus are adapted to be active from autumn to winter (from early October to early February) in mountainous areas of medium to high altitudes (2100-2800 m).
