Dissomphalus nanellus Evans, 1969   ( Figs. 131–135 View FIGURES 131–137 )

Dissomphalus nanellus Evans 1969b: 520–521   , Sarazin 1986: 296, Gordh & Moczar 1990: 224.

Diagnosis. — Male. Head as figure 131. Mandible tetradentate. Clypeus tridentate, lateral teeth wider than the median. Frons coriaceous, punctures inconspicuous. Eye bulging. Vertex slightly convex, corners rounded. Pronotal disc depressed forward. Hypopygium with median stalk 2.0 X the length of plate, posterior margin straight. Metasomal tergite II with pair of antero­lateral depression rounded, very shallow and inconspicuous, each one with small tuft of hairs ( Fig. 132 View FIGURES 131–137 ). Genitalia ( Figs. 133–134 View FIGURES 131–137 ): paramere wide, apex curved inward, dorsal margin nearly straight, ventral margin concave; volsella with cuspis angled apically inward, digitus produced basally; aedeagus with ventral ramus shorter than dorsal body, laminar, surface horizontal, wide, inner and outer margins straight and parallel, apex inclined; dorsal body with two pairs of apical lobes, the dorsal pair short and angled medially, the ventral pair laminar, surface vertical, apex rounded and angled downward in lateral view ( Fig. 135 View FIGURES 131–137 ), inner surface stout, membranous and hairy; apodeme extending the elliptical basal ring.

Material examined. — HOLOTYPE: male, JAMAICA, 4,000 feet, Hardwar Gap, 6.VII.1966, Howden & Berger col. ( CNCI, type nº 7,550).  

Comments. — Azevedo (1999c) described the genitalia of this species for the first time and made diagnosis based on the paratype, but there are some differences between this specimen and the the holotype analyzed here. In the holotype, the ventral ramus of aedeagus is horizontal, the dorsal lobe of dorsal body of aedeagus is more angled and the median lobe clypeus is tridentate, whereas in the paratype the ventral ramus of aedeagus is vertical and the median lobe clypeus is subtrapezoidal
