Dissomphalus ferocus   sp. nov. ( Figs. 72–76 View FIGURES 72–87 )

Description. — Male. Body length 5.1 mm; LFW 3.25 mm. Color: head and mesosoma black; metasoma and clypeus dark castaneous; antennae, mandible and legs castaneous; palpi light castaneous; wings subhyaline.

Head: mandible bidentate. Clypeus trapezoidal. First four antennal segments in a ratio of 18:7:6:7, segment XI 1.57 X as long as broad, sensillae conspicuous. Frons strongly coriaceous, punctures shallow, separated by 0.2–1.0 X their diameters. LH 1.02 X WH; WF 0.63 X WH; 1.38 X HE; OOL 1.39 X WOT; DAO 0.34 X WOT; posterior ocelli distant from the vertex crest 1.77 X DAO, frontal angle of ocellar triangle acute. Vertex slightly concave medially, corners rounded. VOL 0.48 X HE.

Mesosoma: thorax coriaceous as frons. Pronotal disc 0.51 X length of mesoscutum. Propodeal disc 0.59 X as long as wide, with small polished area posteriorly. Fore femur 3.3 X as long as thick.

Metasoma: tergite II with pair of elliptical pits, distant each other 6.5 X their length, distant from posterior margin of tergite I 0.88 X their length, closer to the lateral margin than the middle, placed at the inner area of rounded shallow depression ( Fig. 72 View FIGURES 72–87 ), inner part of each pit covered by translucid sclerite, so that the hole is hemispheric and inclined, from which emerges small tuft of hairs ( Fig. 73 View FIGURES 72–87 ). Hypopygium with median stalk 1.7 X as long as plate, posterior margin straight. Genitalia ( Figs. 74–75 View FIGURES 72–87 ): paramere with apex slightly convex and directed inward, dorsal margin straight, ventral margin badly convex; basivolsella dilated and well­differentiated from basiparamere internally; aedeagus with ventral ramus as long as dorsal body, angled medially outward, apical area with four teeth, being the apical one larger; dorsal body with three pairs of apical lobes, outer pair bulging, basal margin concave, angled laterally, apex rounded, ventral margin denticulate and excavated medially ( Fig. 76 View FIGURES 72–87 ), inner pairs membranous, stout and hairy, being the median pair longer than the ventral one; basal process with two teeth projected outward; apodeme extending beyond the elliptical genital ring.
