Distribution. Endemic to Ethiopia.

Description. Habitus ( Figure 27 ). Male. Antennae long, at least twice the body length. First antennal segment longer than fastigium of vertex, as long as an eye. Eyes are prominent. Face smooth. Pronotum slightly saddle-shaped, rugose, ventral margin more or less straight, hind angle broadly rounded, posterior margin slightly excised, anterior margin straight. Tegmina just longer than pronotum, hardly reaching the 3rd abdominal tergite, apical external angle about 45°, rounded ( Figure 15).

Coxae unarmed, fore and mid femora with 0–1 pre-apical spine on ventral margin; hind femora with 5 ventral spines. Fore tibiae with open tympanum on both sides, 4–5 spines on ventral margins + 2 apical spurs on each side (1 on ventral and 1 on dorsal margin), mid tibiae with 3–4 ventral spines + 2 apical spurs and another on dorsal inner margin, hind tibiae with 4–5 ventral spines + 2 apical spurs and another dorsal spur.

The appendage of the last tergite widened towards the apex, more or less straight with acute lateral angles; one small spine is present under each margin of the appendage. At the base of the appendage, before the spine is present the 9th tergite modified as an inflated extrusion that ends with 2 flat and ovoid apices below the abovementioned spine. Cerci short, strongly curved and pointed. Subgenital plate very large, basal part transverse with a broad round emargination posteriorly; the branches are divergent, laterally compressed and converge under the apex of the appendage of the 10th tergite ( Figures 18–21 ).

Female. Same characters as the male except those listed in the following: Tegmina very short, just exceeding the 1st abdominal tergite, not overlapping, their apical external angle about 45°, rounded ( Figure 15). Ovipositor sharply bent upwards near the base with small fine denticles on both apices of the valves. Subgenital plate with rounded margins, almost straight on posterior margin, with a central keel ( Figure 23 ).

P. keffensis is related to P. se m i e n s i s n. sp. and P. antinorii , from which it differs by the shape and length of the tegmina, the male appendage, the shape of the ovipositor, the female subgenital plate and the body size ( Table 3 ).

Colour. Yellowish-green, antennae with 1st and 2nd segments black below, others brownish with yellow rings at the base. Tympanum and upper margins of fore and mid femora, outer margins of hind femora, fore and mid tibiae and tarsi blackish-brown, hind tibiae yellow-green with brown apex ( Figure 27 ).

Measurements. See Table 3 .

Habitat. All the specimens were collected on bushes and large herbs along forest edges ( Figures 2 c, 3a,b)

Etymology. This species is named after the region of Keffa, famous for the origin of wild Coffea arabica .
