Dissomphalus cervoides sp. nov. ( Figs. 33–36 View FIGURES 26–40 )

Description. — Male. Body length 5.25 mm; LFW 3.88 mm. Color: head, mesosoma, clypeus black; metasoma dark castaneous; mandible, antenna, palpi and legs castaneous; wings subhyaline.

Head: mandible bidentate. Clypeus trapezoidal. First four antennal segments in a ratio of 19:5:4:7, segment XI 1.79 X as long as broad. Frons coriaceous, punctures large, shallow, separated by 0.5–1.5 X their diameters. LH 0.96 X WH; WF 0.57 X WH; 1.22 X HE; OOL 1.13 X WOT; DAO 0.3 X WOT; posterior ocelli distant from the vertex crest 2.67 X DAO, frontal angle of ocellar triangle acute. Vertex slightly convex, corners rounded. VOL 0.53 X HE.

Mesosoma: thorax coriaceous, punctures smaller and more distant each other than those of frons. Pronotal disc 0.58 X length of mesoscutum. Propodeal disc 0.55 X as long as wide. Fore femur 3.13 X as long as thick.

Metasoma: tergite II with pair of small, and very shallow lateral depressions, with tubercle, which has pit on the top, which has dense tuft of hairs directed backward, tubercles distant from the posterior margin of tergite I their own diameters, distant from the median line as much as from the lateral margin of tergite II ( Fig. 33 View FIGURES 26–40 ). Hypopygium with posterior margin straight, with pair of small conical median protuberances. Genitalia ( Figs. 34–35 View FIGURES 26–40 ): paramere longer than basiparamere, apex arched inward and thin, dorsal margin straight, ventral margin straight below and concave above; basivolsella with inner margin micro­serrated; aedeagus with ventral ramus shorter than dorsal body, laminar, apical half translucent and thin, apex with top and an inner thin and top­rounded expansions, apex constricted below, inner margin with quadrate expansion; dorsal body with three pairs of apical lobes ( Fig. 36 View FIGURES 26–40 ), the dorsal pair thick, base with outer projection, surface vertical and parallel, wide in lateral view, arched downward, dorsal margin angled, ventral margin micro­serrated, ventral pair membranous, stout, rounded, much shorter than dorsal one, median pair less stout, less membranous and shorter than the median one; basal process with pair of lateral rounded expansions upward; apodeme extending beyond the elliptical genital ring.

Variation. — Clypeus lighter, depression of metasomal tergite II deeper, tubercles smaller or closer to posterior margin of tergite I, tufts less dense; outer lobe of dorsal body of aedeagus converging below.

Etymology. — The specific epithet refers to the shape of ventral ramus of aedeagus, which resembles the horns of deer.
