Measurements. Males. Body length: 30.4±1.8 (27.6–33.5); pronotum length: 7.2±0.4 (6.6–7.7); pronotum height: 6.9±0.4 (6.4–7.5); hind femur: 25.4±1.0 (24.0–27.1); hind tibiae: 30.0±1.0 (28.9–31.5); tegmina: 41.7±0.7 (40.5–42.8); tegmina width: 9.5±0.2 (9.1–9.8); width tegmina/length pronotum: 1.2–1.4. Females. Body length: 32.7±0.2 (32.6–32.9); pronotum length: 7.1±0.1 (7.0–7.2); pronotum height: 6.9±0.1 (6.8–7.0); hind femur: 26.6±1.0 (25.9–27.3); hind tibiae: 29.9±0.8 (29.3–30.5); tegmina: 43.6; tegmina width: 10.1±0.1 (10.1–10.2); ovipositor: 4.95±0.1 (4.9–5.0); tegmina width/pronotum length: 1.4.

Diagnosis. A medium sized species characterized by at least 5 dull brown markings in at least 3 hexagons on the yellow-green tegmina.

Description. Male. General habitus and colour pattern. Medium-sized with a characteristic colour pattern of 5–7 spots on the tegmina. First two antennal segments are yellow with a black spot, the remaining antennomeres are yellow. Head and legs are yellow with blackish areas (fore femora, tympana of fore tibiae, second half of mid and hind femora). Face yellow. Pronotum green, lateral lobes with a whitish area, metazona darker than prozona. Tegmina slightly oval, yellow-green with black markings at the very base, and 5–7 brown dull markings distributed along its length ( Fig. 15 ). Head and antennae. Eyes oval, fastigium of vertex sulcate. Thorax and legs. Tympana of fore tibiae open on outer, closed on inner side. Prozona of pronotum clearly narrower than metazona. Anterior margin of pronotum slightly concave, posterior margin rounded. Lower margin of pronotal lobes without the concavity present in other species of the genus. A small black spot is present on the base of the tegmina, more or less hidden by the pronotum. Tegmina are 4.0–4.4 times longer than wide. The stridulatory area of the left tegmen is short. The stridulatory file consists of 28–30 teeth, the inner 4 more spaced than the outer ones ( Fig. 54 ). Fore coxae unarmed. Fore femora with 5 inner ventral spines, fore tibiae with 6 inner and outer ventral spines, and 3 dorsally. Mid femora with 6–7 outer ventral spines, mid tibiae with 9–10 outer and inner ventral spines, 2–3 spines on outer and inner dorsal margins. Hind femora with 5 inner ventral black spines and 0–1 on outer ventral margin. Hind tibiae little curved, with 17–18 spines on outer and 10–11 on inner ventral margin. Abdomen. Cerci are long and in-curved, with an apical hairy sclerotized black tip, ending with two small dents ( Fig. 83a ). The subgenital plate is triangular, long and narrow, the apex is concave and styli are absent ( Fig. 83b ).

Female. Similar to male. Ovipositor is short and gently up-curved with small teeth only at the lower apical valve. The subgenital plate is triangular with a straight apex. Cerci are in- and up-curved.

Etymology. This species is characterized by at least five (from Latin: quinque) brown markings (in latin: macula) on the tegmina; quinquemaculata is a feminine adjective.

Affinities. A. quinquemaculata is related to A. hydatinoptera and A. simplicinervis , morphologically very similar to A. simplicinervis . Characterized by its brown markings on tegmina and the stridulatory file. In addition, its hind femora are comparatively shorter than those of A. simplicinervis .

Distribution. Central African Republic, Ivory Coast, Gabon and Togo, probably also occurring in suitable habitats between these localities.
