(Figs 1, 12, 26, 40, 48, 55, 69, 83, 97, 111, 125, 133 –137, 150, 157; Tables 1–4)
Psorodonotus davisi Karabag 1956: 16 (partim).
Material examined. Holoype, male; TURKEY: Giresun, Şebinkarahisar, Tamdere, 40o28.274'N, 0 38o 23.117'E, 1650–1952 m, 12.07.2011 (leg. B. Çıplak, S. Kaya, E.M. Korkmaz & D. Chobanov) (AUZM); Paratypes, 27M, 8F, same data as holotype; 1F (paratype of P. davisi), Giresun, Balaban Mts., 2000–2400m. above Tamdere, 20.8.1952 (T. Karabağ) (NHM).
Diagnosis. Psorodonotus giresun sp. n. is belonging to the Specularis Group and shows close affinities with P. soganli by sharing a typical male cercus shape with a basally widened tooth. The new species differs from its sister species by (1) the smaller number of stridulatory pegs, (2) the song phrase consisting of two-three elements, (3) the shorter duration of the song phrase and (4) the small incision of female subgenital plate. Our unpublished molecular data suggest that there is no gene exchange between these two species and they shared a common ancestor about two million years ago.
Etymology. Named after its type locality beloging to the Giresun Province of Turkey.
Description. Male (holotype). Medium sized for the genus and for the species group.
Thorax. Pronotum (Fig. 12) long, at least one and a half the length of fore tibia and gradually widened backward in metazona. Disc of pronotum flattened, depressed in the middle, with rounded lateral margins and widely rounded hind margin, smooth and shiny in prozona and weakly tuberculate in metazona. Paranota smooth and shiny. Tegmina reach to the end of the sixth abdominal tergite and are covered by pronotum up to their onefourth (Fig. 40). The stridulatory peg number varies between 86 and 116 (mean 99). Hind femur extends beyond the tip of abdomen.
Abdomen. Cercus length (Fig. 69) moderate for both the genus and the species group; with a short, robust, basally widened tooth located close to the base. Anal tergite (Fig. 55) transverse, with a truncate hind margin. Subgenital plate wide in the base and weakly tapering distally in its apical third, with a very shallow triangular incision and wide apical lobes; the length of styli is about one-third of the medial length of subgenital plate. Titillators (Fig.97) are weak, with narrow and smooth basal arms and narrow spinose apical arms; spinules of apical arms ordered in a single row dorsally.
Colouration. General colouration blackish brown. Vertex of head and disk of pronotum light brown or yellowish brown. Paranota blackish brown. Tegmina brown with yellow veins. Hind femur and tibia blackish brown, Abdomen pale blackish brown. Cerci dirty brown.
Female. Pronotum similar to that of male (Fig. 26), tubercles in metazona are relatively prominent when compared to male. Tegmina fully covered by pronotum, reduced to scale-like appendages hardly overlapping dorsally. Subgenital (Fig. 125) plate short, transverse, with a small incision and triangular lobes at hind margin. Ovipositor (Fig. 111) slender, long, roughly 3 times of the pronotum length.
Colouration. As in male.
Distribution. The new species occurs in the alpine zone of the North-east Kaçkar Range in the Rize Province of Turkey (Fig. 1).
