Erymus puphan nov.sp.

T y p e m a t e r i a l: Holotype: NE Laos, Hu Phan Prov. , Ban Saluei, Pu Phan mts, 1500-2000 m, 20.15N, 102.02E, D. Hauck 2.IV-1.V.2001 (cS).

D e s c r i p t i o n: Body length 4.5 mm; length from anterior margin of head to posterior margin of elytra 2.5 mm. Peculiar body by the general structure, narrow and slender, closely related to E. minutus BORDONI 2004 from Borneo, but slightly longer, with more protruding eyes and blackish coloration. Head black, pronotum and abdomen brown black, elytra and antennae brown, legs testaceous. Head ( Fig. 8 ) of peculiar size, slender in shape than other species of the genus, anteriorly dilated, with very protruding eyes. Surface shiny, with distinct and scattered punctures. Pronotum narrow, narrower and longer than head, with anterior margins very oblique and largely rounded anterior angles. Surface shiny, with dorsal series of 6 very scattered punctures and lateral series of 3 anterior punctures. Elytra very large, longer and wider than pronotum, dilated back- wards, with distinct humeri. Surface shiny, with some series of punctures. Abdomen with fine and dense transversal micro striature and fine punctation.

Male genital segment and sternite of the same as in Figs 9-10 . Aedeagus ( Fig. 11 ) very tiny (0.48 mm long), with long parameres and internal sac with an S-like brown structure.

D i s t r i b u t i o n: Known only from the type locality.

E t y m o l o g y: The epithet is based on the type locality, Pu Phan Mountains as a noun in apposition.

N o t e: As I mentioned in the introduction, I propose again the figures of the sexual characters of the species described in the contribution of 2003, as unclear in that publication: Oculolabrus laotianus BORDONI ( Figs 12-14 ) and Atopolinus sulcatus BORDONI ( Figs 15-18 ).
