Dissomphalus soniae Brito & Azevedo , sp. nov.
( Figs 1C View FIGURE 1 , 6H View FIGURE 6 )
Diagnosis. This species is easily recognized by having the aedeagal dorsal valve robust, the inner median filament anterior to the aedeagal dorsal lobes and the basal cover plate with two elliptical lines, basivolsella without protuberance and apex of the aedeagal ventral valve very narrow.
Description. Head. Mandible with three distal teeth. Median clypeal lobe subtrapezoidal, with one rounded very short tooth; median clypeal carina high in profile, complete or nearly so, arched in profile. Frons weakly coriaceous, punctures large and dense. Vertex crest straight or nearly so. Dorsal pronotal area with anterior margin ecarinate. Tergal process submedian, consisting of tuft with few setae, without depression. Posterior hypopygeal margin sinuous. Genitalia. Harpe entirely wide, apical margin truncate, abaxial margin not projected; gonostipes shorter than harpe, ventral margin not excavated until outer margin of basivolsella; digitus short, basidorsal corner poorly projected; basivolsella without protuberance, without spines; aedeagal ventral valve with apex anterior to apex of dorsal one, evenly narrow; inner margin sinuous; outer margin outcurved, curved laterad; aedeagal dorsal valve bottle-shaped or nearly so, with two pairs of apical lobe; outer lobe long, narrow, apical margin rounded and posterad; apex of inner median filament anterior to apex of lobe, directed posterad; basal cover plate entirely wide, posterior margin straight or nearly so; apodeme extending beyond genital ring.
Material examined. Holotype, 1♂: BRAZIL: Amazonas , Estirão do Equador, Rio Javari, X.1979, M. Alvarenga ( PMAE).
Etymology. This species is named after the physicist Sonia Guimarães, first black woman professor at the Institute of Aeronautical Technology (ITA).
Distribution. Brazil (Amazonas).
Remarks. It is similar to D. guidonae sp. nov. by having the harpe narrow with similar dorsal margin, the apex of inner median filament anterior to the aedeagal dorsal outer lobes, and the aedeagal ventral valve very slender. However, D. soniae sp. nov. has the basal cover plate very wide with posterior margin straight and with two sclerotized elliptical lines, whereas D. guidonae sp. nov. has the basal cover plate narrow with posterior margin broadly incurved without two elliptical sclerotized lines.
