Karsch (1893). Berlin Ent. Z., 38: 128.
Type locality: SIERRA LEONE. Depository : MfN, Berlin. Kind of type: holotype male.
Material examined. SIERRA LEONE. ♂ holotype , 2♂. CAMEROON. Barombi Station (1♂). Mukonje Farm, R. Rohde (2♂, 1♀) ( RBINS). Buea (2♂) ( NHMS) . TOGO. Misahohe 14.VI.1894, Baumann (2♀) ( MfN). DEMOCRATIC REPUBLIC CONGO . Kinshasa 18–24.XII.1971, M. Spadone (1♂) ( MZUF).
Tegmina width: 9.7–14; tegmina length/width: 3.2–4.1; tegmina width/pronotum length: 1.9 ( Heller et al. 2014).
Characters. Species of medium size (body length ♂ 33 mm) ( Fig. 25 View FIGURES 21–25 ). Easily distinguished from other Euarantia species by a large inner spine on the male cerci. A. incerata was erronously recorded by Karsch (1889) from Sierra Leone and Cameroon as A. fatidica because of the similarity of the male cerci. However, the male cerci of A. fatidica have a much smaller inner spine and the whole habitus is different. A. fatidica shows the typical habitus of the subgenus Arantia . Characteristic is the expanded furrow dorsally on the tibiae. Later Karsch (1893) described the specimens from West Africa as a separate species, A. incerata . Griffini (1908) examined both sexes from Mukonje Farm ( Cameroon) and described the female. The posterior margin of the pronotum is brown, the basal area of tegmina black, the fore femora as long as the pronotum. Fore femora have 5–7 inner ventral spines, mid femora are unarmed or have 4–5 small outer spines, hind femora have 6–8 very small inner spines and 2–9 outer ventral species. The hind femora are comparatively short. The male cerci are stout and round at base, tapering towards the apex with a large sclerotized spine midway on the inner side. The apex of the male cerci are laterally flattened and inwardly curved ( Figs 89a, 89b View FIGURES 85–95 ). Styli are present. The subgenital plate of the female is short and pointed. The ovipositor has two lateral protuberances.
Distribution. West Africa and Central Africa (records from Sierra Leone, Togo, Democratic Republic Congo and Cameroon).
