Saussure (1899). Abh. Senckenb. Natforsch. Ges., 21: 615.

Type locality: MAURITIUS. Depository : MHNG, Geneva. Kind of type: holotype male.

Tegmina width: 10; tegmina width/pronotum length: 1.3 ( Heller et al. 2014).

Characters. A. dentata is a species of medium size (body length ♂ 35 mm). Only two male specimens are known, but one of them comes from Cameroon ( Saussure 1899; John Hollier, pers. comm.) and thus very likely belongs to A. orthocnemis . It is characterized by narrow and translucent tegmina with a black spot at their base. Further characters are a rounded margin of the pronotal lobes. The male cerci are rather stout and have an inner spine, as A. orthocnemis (compare Figs 76 and 77 ).

Remarks. A. dentata is morphologically very similar to A. orthocnemis . However, the localities of both taxa ( A. dentata known from Mauritius in the Indian Ocean, A. orthocnemis occurring in Central and West Africa) are far apart geographically and therefore we decided not to synonymize these two species.

Distribution. Known only from the island Mauritius in the Indian Ocean.
