Aegidiellus dentipenis Frolov, Akhmetova & Vaz-de-Mello
Original description: Frolov et al., 2017
Type locality: Brazil, Rio de Janeiro, near Juturnaiba Lake.
Type depository: CEMT.
Diagnosis. Ae. dentipenis can be easily separated from the other species of the genus by the shape of the aedeagus: phallobase wider, its anterodorsal margin not protruding; parameres wider, their lateral margin with deep sinuation basally forming a tooth. It also differs in having a spiculum gastrale of intermediate form between T-shaped (similar to that in most Aegidium and in Paraegidium) and triangular (as in other Aegidiellus species).
Distribution. The species is known from one locality near Juturnaiba Lake, Rio de Janeiro Province, Araruama Municipality, Brazil.
