Pselaphodes dalatensis View in CoL sp. nov.

( Figs 4B View Fig , 6 View Fig )

Type material (1 specimen). HOLOTYPE: VIETNAM: LÂM Đồ NG: ♂, ‘VIETNAM.Da Lat, Institute of Biology , at light, No. 765., 10.XII.1994, S. Mahunka, Gy. Sziráki & L. Zombori’ ( MHNG) .

Diagnosis. Male body length 3.85 mm.Antennomeres 9–11 greatly modified and forming distinct club, antennomere 9 broadly impressed on ventral surface, with short basal protuberance and setose tuft above protuberance, apical margin strongly elevated and expanded to form irregular lamina-like projection, antennomere 10 with mesal margin bluntly projected at base, antennomere 11 strongly constricted at base. Protrochanter with sharp ventral spine at base and tiny ventral tooth near apex, profemur with large triangular ventral projection at middle, protibia with two roundly-triangular projections along mesal margin in apical half; mesotrochanter with acute ventral spine. Hornlike metaventral processes short, in lateral view triangular, narrowing apically. Aedeagus with moderately long parameres; endophallus composed of two elongate sclerites. Female unknown.

Description. Male ( Fig. 4B View Fig ). Body length 3.85 mm. Head approximately as long as wide, HL 0.68 mm, HW 0.70 mm; eyes prominent, each composed of about 45 facets. Antennomeres 2–7 each moniliform, except for antennomere 3 distinctly longer than 2 and 4; antennomeres 9–11 ( Fig. 6A View Fig ) greatly modified, antennomere 9 broadly excavated on ventral surface, with short basal protuberance, apical part strongly elevated and expanded to form irregular lamina-like projection, with setose tuft below projection, antennomere 10 moderately curved in lateral view, its mesal margin bluntly projected at base, antennomere 11 strongly constricted at base. Pronotum ( Fig. 6B View Fig ) slightly longer than wide, PL 0.70 mm, PW 0.67 mm, narrowing apically at apical 2/5. Elytra much broader than long, EL 1.09 mm, EW 1.35 mm. Hornlike metaventral processes ( Fig. 6C View Fig ) short, in lateral view sub-triangular and narrowing apically. Protrochanter ( Fig. 6D View Fig ) with sharp ventral spine at base, and tiny ventral tooth near apex; profemur with large triangular ventral projection at middle; protibia ( Fig. 6E View Fig ) with two roundly-triangular projections along mesal margin in apical half; mesotrochanter ( Fig. 6F View Fig ) with acute ventral spine; mesofemur ( Fig. 6F View Fig ), metatrochanter and metafemur ( Fig. 6G View Fig ) simple. Abdomen broad at base and narrowed posteriorly, AL 1.28 mm, AW 1.28 mm. Aedeagus ( Fig. 6H–J View Fig ) with elongate parameres, each ( Fig. 6E View Fig ) having four thick apical setae; endophallus composed of two elongate sclerites (note: the median lobe of the aedeagus is broken in holotype).

Female. Unknown.

Comparative notes. This is another distinctive species, the male of which can be rather easily distinguished from all congeners by unusual forms of the antennal club and protibia.

Etymology. The new species name, dalatensis (- is, - e), is a latinized adjective given after the type locality, Da Lat city.

Distribution. Vietnam: Lâm Đồng.
