Dissomphalus magnus Redighieri & Azevedo, 2006: 324 –326 (♂, holotype from Brazil).
Diagnosis. Male. Mandible with three apical teeth. Median clypeal lobe trapezoidal. Frons coriaceous, punctures small, shallow. Ocellar triangle distant from vertex. Vertex straight, small median depression, corner rounded. T2 with pair of very shallow and circular depressions, not reaching anterior margin, each depression with setae linear tubercle, inclined, posterior part directed inward, latero-anterior area depression sparse-setae. Hypopygium with slender stalk, posterior margin straight, corner rounded. Genitalia: paramere short or wide, dorsal margin evenly very developed, apex concave, very produced dorsally; volsella with stout protuberance near digitus, base volsella with species-group of teeth; aedeagal ventral ramus very short, base wide, apical half narrow, slightly convergent, apex very sharpened, inner margin of base sinuous, outer margin expanded laterally, so that ramus surrounds dorsal body laterally, this margin with small tooth; aedeagal dorsal body very wide with apex in lateral view, laminar, lamina completely folded longitudinally in ventral side, inner lamina membranous, sinuous, setae inside, outer lamina with series of grooves; in dorsal view body is slightly wider in base; inner ventral margin base of genitalia angulate. Female unknown.
Variations. The main variations found in this series are the pronotal disc strongly setose and the aedeagal ventral ramus strongly bifurcated.
Remarks. This species was previously known from Brazil (Paraíba) (Redighieri & Azevedo 2006). Now it is recorded for the first time from Ceará and Maranhão.
This species has the tergal process with the lateral depression with one pair of tubercles and the lateral margin setose. Such characteristics are diagnostic of the setosus species-group. Thus, we transfer it into this species-group.
