description: Dissomphalus w-aedeagus Colombo & Azevedo, sp. nov.
(Figs 6, 27, 117–120)
Description. Male. Head and mesosoma black; metasoma dark castaneous. Mandible with two apical teeth; clypeus broadly projected forward, median tooth ill defined; frons weakly coriaceous, punctate. Pronotal disc weakly coriaceous. T2 with pair lateral depressions, reaching lateral margin tergite; lateral margin setose, wide pitted tubercle with tuft of setae. Posterior hypopygeal margin straight. Genitalia: paramere very narrow in dorsal or ventral view, apex rounded, larger than basiparamere; cuspis very long, extending digitus to the paramere base, very narrow; digitus small, serrate; aedeagal ventral ramus larger than dorsal body, wide, tubular, invaginated apex; aedeagal dorsal body with two pairs apical lobes, outer pair with apex irregular in lateral view, inner pair serrate, basal process weakly arched; apodeme not extending beyond genital ring. Female unknown.
Variations. Paramere wider in lateral view.
Remarks. This species is now included in setosus species-group by having the tergal process with lateral depression with pair of tubercles and lateral margin setose. This species has the tubular aedeagal ventral ramus, characteristic brasiliensis species-group. However, the aedeagal dorsal body is not as small as diagnosed for this species-group. Within the setosus species-group, this genitalia is totally different from other species, mainly because of the paramere is very narrow, in dorsal view and, the aedeagal ramus ventral is invaginated apex.
This species goes to couplet 11 on the key proposed by Redighieri & Azevedo (2006) and should be read as:
11. Paramere very narrow in dorsal or ventral view; aedeagal ventral ramus with invaginated apex; aedeagus w-shaped.......................................................................................... D. w-aedeagus sp. nov. - Paramere wide or when narrow, only in dorsal view; aedeagal ventral ramus without invaginated apex; aedeagus never wshaped............................................................................................ 11a 11a. Median clypeal carina high; aedeagal ventral ramus with apex rounded and curved outward....................................................................................................... D. distans Redighieri & Azevedo - Median clypeal carina low; aedeagal ventral ramus with apex acute or when rounded, not curved outward............... 31
