Material examined. DEMOCRATIC REPUBLIC CONGO. Centre de Recherche en Sciences Naturelles in Irangi, ca. 100 km (north) west of Bukavu (♂ holotype) ( MfN) .

Tegmina width: 7–10.5; tegmina length/width: 4.0–4.2; tegmina width/pronotum length: 1.3–1.7 ( Heller et al. 2014).

Characters. A gracilicercata is related to A. orthocnemis (compare Figs 9 and 10 ). Both species share a similar habitus and shape of the male cerci which are long and slender with an inner sclerotized ridge and an inner basal spine. However, in A. orthocnemis the male cerci are not as long and slender as in A. gracilicercata and the inner spine or process located at the inner base of the male cerci is differently shaped between both species (cf. also Heller et al. 2014) ( Figs 79a, 79b ).

Distribution. Known only from the type locality, Bukavu area in the border region of the Democratic Republic of the Congo with Rwanda, Central Africa.
