Dissomphalus deaneae Brito & Azevedo , sp. nov.
( Figs 1E View FIGURE 1 , 3G View FIGURE 3 )
Diagnosis. This species is easily recognized by having the apex of inner median filament aligned with apex of aedeagal lobes, the basal cover plate narrow with a median region incurved, and the abaxial region of harpe projected.
Description. Head. Mandible with three distal teeth. Median clypeal lobe subtrapezoidal, with one angulate large tooth; median clypeal carina low in profile, straight in profile or nearly so. Frons coriaceous, punctures large and sparse. Vertex crest straight or nearly so. Dorsal pronotal area with anterior margin carinate. Tergal process lateral, with tuft of setae inside a tubercle. Posterior hypopygeal margin incurved medially. Genitalia. Harpe wide basally, apical margin rounded, abaxial margin 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 aligned with apex of dorsal one, wide, progressively narrowing apicad; inner margin outcurved; outer margin slightly sinuous, slightly curved dorsad; aedeagal dorsal valve narrow, with two pairs of apical lobe; outer lobe short, very narrow, apical margin rounded, and posterad; apex of inner median filament aligned with apex of lobe, directed posterad; basal cover plate entirely narrow, posterior margin slightly incurved medially; apodeme extending beyond genital ring.
Variation. Tergal process of one specimen without tubercle, inner median filament almost aligned with aedeagal dorsal lobes.

Distribution. Brazil (Minas Gerais, Paraná, São Paulo).
Etymology. This species is named after the parasitologist Maria José Deane, whose work helped improve Brazilian public health by eradicating several tropical diseases.
Remarks. It is similar to D. tupinikim by having the harpe elongated with an abaxial region projected, and the aedeagal dorsal valve narrow. However, D. deaneae sp. nov. has the tergal process with tubercles, the apex of inner median filament aligned with apex of outer lobes, and the aedeagal ventral valve with apex laterad, whereas D. tupinikim has the tergal process with tuft of setae, the apex of inner median filament posterior to aedeagal dorsal lobes, and the apex of aedeagal ventral valve directed ventrad.
