Material examined. ETHIOPIA: Gondar , Semien National Park, Sankaber Camp (3300 m), 30.XII.1999, G. Osella (Ƌ holotype, BMPC).

Distribution. Endemic to Ethiopia.

Description. Male. First antennal segment longer than fastigium of vertex, as long as an eye. Eyes are prominent. Face smooth. Pronotum not saddle-shaped, rugose, lower margin more or less straight, hind angle broadly rounded, fore margin straight. Tegmina as long as pronotum, just exceeding the 2nd abdominal tergite, their apical external angle about 45°, rounded ( Figure 28).

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

The appendage of the last tergite widened towards the apex, more or less straight with acute lateral angles; a 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 rounded apices below the above-mentioned spine. Cerci short, strongly curved and pointed. Subgenital plate very large, basal part transverse with a broad round emargination behind; the branches are divergent, laterally compressed and apically enlarged, and converge under the apex of the appendage of the 10th tergite ( Figure 18–21 ).

Female. Unknown.

P. semiensis is related to P. keffensis and P. antinorii , from which it differs by tegmina shape and length, male appendage, and body size (see Tables 3 ).

Etymology. The species is named after the Semien National Park, one of Ethiopia’s richest areas in fauna and flora species and endemic taxa.
