description: <i>Pselaphodes jendeki sp. nov.</i> (Figs 7 A, 8) <b>Type material</b> (8 specimens). HOLOTYPE: <b>VIETNAM: LÀO CAI:</b> &amp;male;, ‘VIETNAM N 22°20′N, 103°50′E, SAPA (Lao Cai) 25.5- 10.6.1991, leg. E. Jendek’ (MHNG). PARATYPES: <b>VIETNAM: LÀO CAI:</b> 7 &amp;male;&amp;male;, same label data as for holotype (MHNG, SNUC). <b>Diagnosis.</b> Male length 3.80–3.85 mm. antennomeres 9–11 each elongate, almost simple, antennomere 9 with small disc-like process near apex. Protrochanter with acute ventral spine, profemur with sharp spine at middle; mesotrochanter with acute ventral spine, mesotibia with small, blunt apical tubercle. Horn-like metaventral processes considerably short, apices truncate and bent downwards. Median lobe of aedeagus asymmetric; parameres short; endophallus composed of three sclerites. Female unknow. <b> Description. <i>Male</i></b> (Fig. 7 A). Body length 3.80–3.85 mm. Head slightly longer than wide, HL 0.68–0.73 mm, HW 0.68–0.70 mm; eyes prominent, each composed of about 40 facets. Antennomeres 2–8 each moniliform, antennomeres 9–11 (Fig. 8 A) each strongly elongate and enlarged, antennomere 9 with small disc-like structure near apex. Pronotum (Fig. 8 B) approximately as long as wide, PL 0.65–0.68 mm, PW 0.62–0.67 mm, sides narrowing anteriorly at apical two-fifths. Elytra broader than long, EL 1.10–1.20 mm, EW 1.30–1.40 mm. Horn-like metaventral processes (Fig. 8 C) short and broad in lateral view, apically bifid, upper apex acute, apex truncate.Protrochanter (Fig. 8 D) with thin, acute ventral spine; profemur with sharp ventral spine at middle; mesotrochanter (Fig. 8 E) with acute ventral spine, mesofemur simple, mesotibia (Fig. 8 F) with small apical tubercle; metatrochanters and metafemur (Fig. 8 G) simple. Abdomen broad at base and narrowed apically, AL 1.15–1.20 mm, AW 1.30 mm. Sternite 7 (IX) (Fig. 8 H) hemi-membranous. Aedeagus (Figs 8 I – E) 0.75 mm long, median lobe asymmetric dorso-ventrally, narrowing apically and curved rightwards at apex in dorsal view; parameres much shorter than median lobe, each with three apical setae, endophallus composed of one triangle and two slightly curved, elongate sclerites. <i>Female.</i> Unknown. <b>Comparative notes.</b> This species belongs to the <i>P</i>. <i>tianmuensis</i> species group whose males share almost simple antennal clubs except for antennomere 9 which has a disc-like process near the apex. The new species may be readily separated from allied species by short and truncate horn-like metaventral processes, unique configuration of the aedeagus, as well as by its distribution. <b>Etymology.</b> The new species is named after the Slovak entomologist Eduard Jendek, collector of the holotype. <b>Distribution.</b> Vietnam: Lào Cai.
