Extended description of H. pulveratus View in CoL

A medium-sized species of Hypsugo (FA 32.4–37.6 mm, GLS-i 13.26–14.64 mm, CCL 12.00– 13.20 mm). Ear, muzzle and wings black or nearly black. Keel on calcar elongated but well defined. The fur on the back is long and thick, the nearly black hairs have pale tips, so the general impression is frosty. On the ventral aspect the basal 2/3 of hairs are also black, the distal part medium brown with yellowish-white tips. The cranial profile is elevated with a shallow depression between the rostrum and the braincase ( Fig. 1 View FIGURE 1 ). There are no supraorbital tubercles, the dorsal surface of the rostrum is smooth; basioccipital pits are shallow. Upper canine is thick but relatively short and only slightly exceeds the height of the posterior premolar. P2 relatively large and visible in lateral view.

An exceptionally small individual of the species (FA 32.4 mm, GLS-i 13.32 mm, CCL 12.00 mm) was collected in the Pu Mat National Park, Nghe An Province, Vietnam (registered as IEBR M-1610) and was characterised by short, backward directing (opistognath) upper incisors ( Fig. 1 View FIGURE 1 ) with distinctly convergent tips, developed inner cingular cusp on I2, and weak upper canines. However, in spite of these anatomical differences, based on COI sequences this individual groups very closely to H. pulveratus (~1% sequence divergence). Considering that all the genetically analysed currently recognized species of Hypsugo show very large genetic differences, this individual may just be an aberrant specimen of H. pulveratus with abnormal anterior dentition.
