Description. Male. General aspect brown to black with mix of brown to black and white and green patches. Medially on dorsal abdomen on each tergite tri-angle shaped brown markings bordered by whitish to green area—this pattern fading in preserved insect (see Fig. 3 B and Fig. 6 A, pattern of living female). Head and antennae. Fastigium verticis finger-like elongated, about as long as scapus (Fig. 2 B). Face with broad tri-angled shaped fascia, labrum and mandibles orange-red (Fig. 5, female). Genae green. Antennae long, more than twice the length of body. Scapus with black upper margin and several black dots on green ground. Thorax. Pronotum rugose, rounded, posterior area (in metazona) slightly inflated. Tegmina hidden for most of their length under pronotum, only straight deep black hind margin of tegmina visible. On metanotum with dark black patch. Width of the mirror (see Hemp et al. 2015) on the left tegmen 1.64 mm, its length 1.29 mm. Legs. Fore coxa with rather stout, little curved spine. Fore and mid femora with 3 outer ventral spines, hind femur with 4 outer spines, unarmed on inner side. Fore and mid tibiae with double row of each 4-6 irregular set black-tipped ventral spines and two ventral spurs. Hind tibiae with 3 rows of densely set small black-tipped spines, on dorsal side apically broadening to 4 rows of spines. One long spur on each side dorsally and three pairs of short spurs ventrally. Abdomen. Tenth abdominal tergite at posterior margin wid- ened, with almost straight and callous margin and a slight median indentation (Fig. 1 A). Subgenital plate elongated, posteriorly up-curved and v-shaped incised medially, with finger-like styli (Fig. 1 B). Cerci laterally expanded, with acute process midway and an inner branch divided into two short branches (Fig. 1 A, B).

Female. Similar to male in size and colour pattern (Fig. 2 A, B), also with black fascia in the face and orange-red labrum and mandibles (Fig. 5 A). Ovipositor stout, up-curved (Fig 3 A). 10 th abdominal tergite differentiated into two shallow lobes with callous margins (Fig. 3 B, 4 A). Subgenital plate rectangular with u-shaped incision medially at posterior margin, thus forming two lobes with sinous margins (Fig. 4 B).

Measurements, male (mm) (N = 4). Body length 20.0–22. Length of pronotum 8.0–8.5. Length of hind femur 10.9–11.4.

Measurements, female (mm) (N = 4). Body length 20.5–24.5. Length of pronotum 6.0–6.3. Length of hind femur 11.5–13.0. Ovipositor 10.0.–10.8.

Song. The single recorded male produced isolated echemes in intervalls of about 2 minutes (recording time 45 min). See Fig. 39, 42 and Table 1 for details.

Diagnosis. See at A. maculatus n. sp.

Habitat. Submontane to montane closed forest. Understory dweller found at night in trees and bushes. Recorded between 1750 and 2100 m.

Distribution. Tanzania, North Pare Mountains.

Etymology. The species is named after is speckled colour pattern of many irregular set brown to black and white patches from Latin— guttatus, speckled.
