description: Dissomphalus ashauerae Brito & Azevedo, sp. nov.
(Figs 1B, 3A)
Diagnosis. This species is easily recognized by having the tergal process similar to coronatus species-group, the harpe wide basally, the digitus very wide, large and with posterior margin smooth, aedeagal dorsal lobes short and the basal cover plate very narrow.
Description. Head. Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina low in profile, incomplete apically, straight in profile or nearly so. Frons coriaceous, punctures large and dense. Vertex crest straight or nearly so. Dorsal pronotal area with anterior margin ecarinate. Tergal process submedian, with dense tuft of setae inside of shallow depression. Posterior hypopygeal margin incurved medially. Genitalia. Harpe very wide basally, 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 well delimited with wide protuberance, without spines; aedeagal ventral valve with apex aligned with apex of dorsal one, wide, progressively narrowing apicad; inner margin sinuous; outer margin slightly sinuous, slightly curved laterad; aedeagal dorsal valve narrow, with two pairs of apical lobe; outer lobe short, narrow, apical margin rounded and posterad; apex of inner median filament anterior to apex of lobe, directed posterad; basal cover plate entirely narrow, posterior margin strongly incurved medially; apodeme extending beyond genital ring.
Variation. Median clypeal lobe subtrapezoidal.
Material examined. Holotype, 1♂: BRAZIL, Pará, Oriximiná, Porto de Trombetas, 01°27'S 56°30'W, 14– 24.XII.2006, arm. Malaise, J.Cardoso & G.Costa col. (UFES). Paratypes: BRAZIL, Manaus, Amazonas, 1♂, Res. Ducke, 2m, 17.VII.1992, Adesiva, Vidal & Vidal, col. (INPA); 1♂, Rod AM 010 km 26, mata, IX.2001, arm. Malaise, J.F. Vidal (INPA); Reserva 1208, Malaise, B. Klein col., 1♂, 14.I.1986, 1♂, 29.IV.1987 (INPA).
Distribution. Brazil (Amazonas, Pará).
Etymology. This species is named after the physicist Sonja Ashauer, the first Brazilian woman to complete a doctorate in physics.
Remarks. It is similar to D. napo by having the aedeagal dorsal lobes short, the apex of aedeagal dorsal valve aligned with apex of aedeagal ventral valve, and the inner median filament very short. However, D. ashauerae sp. nov. has the harpe with margin sinuous and wide medially, the basal cover plate very narrow and U-shaped, the digitus short and wide, whereas D. napo has the harpe with dorsal margin straight and not wide basally, the basal cover plate wide and not U-shaped, and the digitus long and narrow.
