- <p><b><i>Dissomphalus rosangelae</i> Colombo & Azevedo, sp. nov.</b></p><p>(Figs 8, 29, 134–140)</p><p><b>Description.</b> Male. Head and mesosoma black; metasoma dark castaneous. Mandible with three apical teeth; median clypeal lobe subtrapezoidal, large median tooth; frons strongly coriaceous, punctate. Pronotal disc strongly coriaceous. T2 with median depression elliptical, not so deep, pair of lateral tubercles, tubercles directed to each other. Posterior hypopygeal margin straight. Genitalia: paramere wide, apex narrow, smaller than basiparamere; aedeagal ventral ramus smaller than dorsal body, laminar, irregular apex, progressively narrowing apically, basal process weakly bifurcated; aedeagal dorsal body with three pairs apical lobes, external pair membranous with apex irregular in lateral view, apical extension in dorsal view, wavy, middle pair sickle-shaped, inner pair serrate; apodeme not extending beyond genital ring. Female unknown.</p><p><b>Variations.</b> Tergal process tubercles with little targeted.</p><p><b>Remarks.</b> This species is now included in <i>vallensis</i> species-group by having the tergal process with median depression with pair of tubercles directed to each other. This species has the genitalia similar to those of <i>D. extrarramis</i>. However, the aedeagal dorsal body of <i>D. rosangelae</i> <b>sp. nov.</b> have three pairs apical lobes with apical extension and, aedeagal ventral ramus have basal process, whereas <i>D. extrarramis</i> have two pairs apical lobes without apical extension and, aedeagal ventral ramus not have basal process.</p><p>This species goes to couplet 8 in the key proposed by Azevedo (1999a) for the <i>vallensis</i> species-group and should be read as:</p><p>8.
