DIAGNOSIS: Length 2.70-3.11 mm. Male: maxillary palpomeres II roundly expanded laterally; head moderately concaved along posterior margin; pronotum with apical portion covered with tufts of setae; protibiae with short apical spur; metatibiae angularly expanded medially near apices.
SUPPLEMENTARY DESCRIPTION
Male ( Fig. 4A, B View FIG ): Length 2.99-3.10 mm. Head longer than wide, HL 0.71-0.73 mm, HW 0.56-0.57 mm, posterior margin moderately concaved; eyes each composed of about 25 facets. Antennal clubs as in Fig. 5A View FIG . Pronotum ( Fig. 5B View FIG ) about as long as wide, PL 0.66-0.68 mm, PW 0.65-0.66 mm, apical portion covered with sparse setose tufts; punctiform median- and lateral antebasal foveae small. Elytra wider than long, EL 0.81-0.82 mm, EW 1.11-1.12 mm. Long metaventral processes with pointed apices ( Fig. 5C View FIG ). Trochanters and femora ( Figs 5D, F, G View FIG ) simple; protibiae ( Fig. 5E View FIG ) with short apical spur; metatibiae angularly expanded medially near apices ( Fig. 5H View FIG ). Abdomen broad at base and narrowed apically, AL 0.81-0.87 mm, AW 1.10-1.11 mm. Tergite VIII ( Fig. 5I View FIG ) and sternite VIII ( Fig. 5J View FIG ) transverse, sternite IX as in Fig. 5K View FIG . Aedeagus length 0.56 mm, with symmetric median lobe apically bent rightwards ( Figs 5 View FIG L-N).
Female: Measurements: BL 2.97-3.11 mm, HL 0.71-0.72 mm, HW 0.55-0.56 mm, PL 0.63-0.64 mm, PW 0.65-0.68 mm, EL 0.75- 0.7 mm, EW 1.11-1.12 mm, AL 0.87-0.98 mm, AW 1.16-1.20 mm. Eyes each compose of about 22 facets. Head, pronotum, protibiae and metatibiae simple; maxillary palpomeres II shortly projecting laterally.
DISTRIBUTION AND NATURAL HISTORY: This species is known from several localities at the Tam Dao Mountain, north Vietnam. Individuals were collected from sifted leaf litter of forest floor.
COMPARATIVE NOTES: As discussed above, N. vietnamicus is allied to Nomuraius sinicus , but can be separated by the relatively shorter pronotum and elytra, the more distinctly medially-expanded apical portion of the metatibiae, the transverse male tergite VIII, and the rightwards-curved apical portion of the aedeagal median lobe.
