Glenobethylus montanus Kieffer, 1910b: 50 (♂, holotype, Pérou, Départ. de Cuzco, Plateau de Cosnipata, altitude de 1000 mètres, en janvier, Garlepp; ZMBH, examined). Synonymized by Azevedo 1999b: 492.

Dissomphalus montanus : Evans 1964: 46, 48 (comb. nov.).

Dissomphalus punctatus : Azevedo 1999b: 942 (syn. nov.).

Diagnosis. This species is easily recognized by the following characteristics: median clypeal lobe subtrapezoidal; tergal process: median, with dense tuft of setae without depression; genitalia with harpe entirely wide, with apical margin truncate; digitus not short, with dorsal corner strongly projected; basivolsella well delimited with wide protuberance, without spines; aedeagal ventral valve with apex posterior to apex of dorsal one, wide, inner margin outcurved, outer margin slightly sinuous, slightly curved laterad; aedeagal dorsal valve bottle-shaped, with two pairs of apical lobes; outer lobe long, narrow, with apical margin acute; apex of inner median filament aligned with apex of lobes; basal cover plate entirely narrow, with posterior margin straight or nearly so.

Distribution. Peru. Now, it is recorded for the first time from Brazil (Amazonas, Maranhão) and Ecuador.

Remarks. Azevedo (1999b) synonymized D. montanus with D. punctatus based on similarity of the genitalia. However, we revalidated this species synonymy, mostly because the general profile of aedeagus is very different.
