Dissomphalus curviventris sp. nov. ( Figs. 41–43 View FIGURES 41–49 )

Description. — Male. Body length 4.38 mm; LFW 3.0 mm. Color: head and mesosoma black; metasoma, clypeus, mandible, antenna and legs dark castaneous; palpi castaneous; wings subhyaline.

Head: mandible bidentate. Clypeus trapezoidal. First four antennal segments in a ratio of 18:5:5:7, segment XI 2.0 X as long as broad. Frons strongly coriaceous, punctures large, shallow, separated by 0.1–1.0 X their diameters. LH 1.05 X WH; WF 0.64 X WH; 1.44 X HE; OOL 1.32 X WOT; DAO 0.32 X WOT; posterior ocelli distant from the vertex crest 1.8 X DAO, frontal angle of ocellar triangle acute. Vertex slightly convex, corners rounded. VOL 0.64 X HE.

Mesosoma: thorax coriaceous and punctated as frons. Pronotal disc 0.5 X length of mesoscutum. Propodeal disc 0.74 X as long as wide. Fore femur 3.5 X as long as thick.

Metasoma: tergite II with pair of very inconspicuous and shallow lateral depressions, with some lateral hairs, each one with tubercle flat­topped, with pit on the top, with tuft of hairs, tubercles slightly closer to the median line than the lateral margin of tergite II. Hypopygium with median stalk 2.5 X as long as plate, posterior margin straight. Genitalia ( Figs. 41–42 View FIGURES 41–49 ): paramere longer than basiparamere, apex thin, slightly curved inward, dorsal margin straight and ill­developed, ventral margin concave above; volsella with cuspis with apex acute, digitus with large basal projection; aedeagus with ventral ramus slightly shorter than dorsal body, laminar, surface vertical, apex converging, ramus thin with apex wide and rounded in lateral view ( Fig. 43 View FIGURES 41–49 ), apex somewhat folded; dorsal body with two pairs of apical lobes, outer pair wide and rounded in lateral view, dorsal margin convex and with surface folded medially, ventral margin serrated ( Fig. 43 View FIGURES 41–49 ), inner pairs stout, membranous and hairy, basal bar surpassing the base of outer lobe; apodeme extending beyond the elliptical genital ring.

Material examined. — Holotype: 1 male, BRAZIL, Paraná, São José dos Pinhais, Serra do Mar , Br277, km 54, 11.VIII.1986, Malaise trap, Profaupar survey ( DZUP) . PARATYPES: BRAZIL, São Paulo, 1 male, Serra da Bocaina, XI.1969 , M. Alvarenga col. ( PMAE) ; Paraná, 1 male, Jundiaí do Sul, Monte Verde Farm , 1 male, Colombo, Embrapa, Br 476, km 20 , 1 male, Fênix, State Reserve ITCF , 46 males, same locality of type, São José dos Pinhais, Serra do Mar, Br 277, km 54, 1.X.1984 – 4.VII.1988, Malaise trap, CIIF or Profaupar survey ( DZUP) .

Variation. — Head wider, metasomal tergite II with depression slightly deeper, tufts larger, with longer hairs.

Etymology. — The specific epithet refers to the ventral ramus of aedeagus with apex folded.
