Karsch (1890). Entom. Nachricht., 16 (23): 358.

Type locality: CAMEROON. Barombi Station . Depository: MfN, Berlin. Kind of type: holotype female.

Material examined. CAMEROON. Barombi Station (1♀ holotype) . Barombi Station , Preuss (1♂) ( MfN) . ANGOLA (1♂) ( MNCN) .

Tegmina width: 7.7–9; tegmina length/width: 5.9; tegmina width/pronotum length: 1.3 ( Heller et al. 2014).

Characters. A. leptocnemis is a medium sized species (body length ♂ 30 mm, ♀ 22.8 mm). Karsch (1890) described the female and considered it related to A. orthocnemis . Later, Karsch (1891) described the male. Tegmina are narrow ( Figs 12–13 ) and may have a black marking at their base. Fore femora have 4 spines, mid femora are unarmed (except for a small spine near the apex), hind femora have 5 outer and 3 inner small ventral spines. Male cerci are long, narrow and in-curved, the apex is sclerotized and rounded ( Fig. 81 ). Styli are present. The subgenital plate of the female is short and rounded. The species is easily distinguished by its long and slender decussate male cerci.

Distribution. Central to Southwest Africa ( Cameroon, Angola).
