Characters. Karsch (1891) described the female, Sjöstedt (1902) reported both sexes from Bonge ( Cameroon), Griffini (1906, 1908) from Fernando Póo ( Equatorial Guinea) and Mukonje Farm ( Cameroon), Chopard (1954) and Ragge (1968b) from the Ivory Coast, and Naskrecki (2009) from Ghana. Typical are the hexagonal areas in the tegmina and black spines present on the hind femora ( Karsch 1891; Bolívar 1906) ( Fig. 49 ). A. galbana has 6 spines on the fore femora, 5 on the mid and 7–8 black spines on inner ventral margin of the hind femora (with a black spot at their base). No spines are present dorsally on the hind femora. The lower margin of the lateral lobes of the pronotum is undulated. The stridulatory file of the left tegmen is rather short and consists of ca. 60 teeth ( Fig. 69 ). Cerci of A. galbana are sinuate and end with a round hairy bulge ( Fig. 104 ). Styli are absent.

Distribution. West and Central Africa (records from Cameroon, Equatorial Guinea, Ghana and Ivory Coast).
