Type locality. Turkey, Hakkari Province, Asagi Olgekli .

Type material. Holotype, ♂ ( MNCR): TR [ TURKEY] – Prov. Hakkari, Asagi Olgekli, 19.6.1988, 2100 m, leg. Barries & Cate / coll. M. Nikodým, Roztoky; paratype, ♀ ( MHNG): TURKEY, Hakkari, Hakkari gec., Kolbasi , 2000 m, 21.VI.2010, leg. G. Sama.

Description of the holotype, male. Body moderately flattened and wide ( Figs 1–3 View FIGURES 1–6 ). Head, pronotum and scutellum black with nearly indistinct violet reflection. Elytra dark reddish-brown. Sternum surface black, abdominal sternites rather light reddish-brown. First and second antennomeres blackish-brown, following antennomeres more or less darkish brown. Femora and tibiae dark brown, tarsi brown. Length 15.2 mm, width 6.3 mm.

Clypeus with sides slightly narrowed backwards, with margins keel-shaped, anterior angles widely rounded, anterior margin medially with small reflexed tooth not projecting from head outline in dorsal aspect ( Fig. 10 View FIGURES 7–11 ). Longitudinal carina from base of medial tooth extending to frontoclypeal suture being somewhat hidden by punctuation. Clypeus and frons with irregular rather dense and large punctures, bearing short brownish setae, in frons punctures somewhere fused into short transversal wrinkles. Integument of head with very indistinct shagreen, shiny. First antennomere large, slightly incurved, swollen distally, with dense and long dark brownish hairs; antennomere 2 about 1/4 length of antennomere 1, swollen, with dense dark setae; antennomeres 3–7 and antennal club with single short delicate setae; antennal club distinctly shorter than antennomeres 3–7 ( Fig. 21 View FIGURES 12–21 ). Mandibles with two short wide teeth, dorsal edge (external angle) slightly convex, without tooth ( Fig. 16 View FIGURES 12–21 ). Maxillary palps rather long, distinctly narrowed distally.

Pronotum moderately convex, widest near posterior 1/3, with sides nearly regularly widely rounded ( Fig. 10 View FIGURES 7–11 ). Pronotal margin keel-shaped. Surface with rather dense and rough irregular punctures and with rather sparse and short brownish hairs; anterior with brash of few thick setae ( Fig. 19 View FIGURES 12–21 ); posteriorly pronotum with glabrous and smooth areas (“mirrors”) with small single punctures, on each side of midline in approximately posterior quarter of pronotum. Integument slightly shagreened, with silky luster. Scutellum large, rounded posteriorly.

Elytra moderately convex, with “striped” (costate) appearance; disc with slightly convex rather narrow intervals with indistinct small sparse punctures and costae with finely concave stripes of rather deep and distinct punctures and with two distinct stripes of rather long yellowish hairs, stripes not reaching elytral base, third interval without hairs, lateral interval with few hairs forming indistinct stripe; elytral edge with stripe of similar hairs reaching elytral apex. Epipleurae separated by weak obtuse declivity nearly reaching elytral apices ( Fig. 3 View FIGURES 1–6 ). Elytral margins with row of short thick setae. Integument of elytra with very indistinct shagreen, rather shiny.

Prosternum with long brownish semi standing hairs, metasternum with yellowish hairs, dense laterally, sparse medially. Metasternum with irregular rather sparse moderately large punctures. Incision between teeth 1 and 2 of protibiae slightly irregularly arcuate, dorsal surface with longitudinal grove with distinct row of small punctures bearing rather long brown setae and reaching approximately level of incision above mentioned ( Fig. 22 View FIGURES 22–30 ). Hind femora moderately thickened, about 2.2 as wide as long, with moderately dense rather short brownish hairs, with row of punctures bearing thick setae on ventral surface and along anterior and posterior margins ( Fig. 26 View FIGURES 22–30 ). Trochanter with prolonged sharp apex, without tooth or ledge Abdominal sternites with rather superficial punctuation somewhat denser and rougher laterally, shallowed medially, and with dense bright yellowish hairs, proximally somewhat hiding integument. 5th abdominal sternite with distinct large glabrous hairless callosity, surrounded by irregular thin setae. Pygidium and propygidium with dense bright yellowish setae hiding integument.

Membrane of hind wings unevenly darkened in approximately distal 3/4 ( Fig. 13 View FIGURES 12–21 ).

Male genitalia. Parameres symmetrical, slightly incurved with sharp apices ( Fig. 33 View FIGURES 31–36 ). Endophallus without lateral bulbs, anterior bulb rather small, not enlarged ( Figs 31, 32 View FIGURES 31–36 ).

Female. Length 14.1 mm, width 5.2 mm ( Fig. 7 View FIGURES 7–11 ). Clypeus with lateral teeth larger than in male, medial tooth slightly protrudes forward in dorsal aspect. Pubescence of head and pronotum somewhat shorter and sparser than in male. Glabrous areas in pronotum (“mirrors”) larger, anteriorly reaching level of posterior 2/5 of pronotum; pubescence shorter and sparser. Elytra somewhat less shiny than in male, hairs in stripes sparser and somewhat shorter. Elytral apices nearly regularly arcuate. Legs shorter than in male, hind femora not thickened, 3.2x longer than wide.

Differential diagnosis. Glaphyrus sabatinellii sp. nov. differs from most Glaphyrus species by the arcuate incision between the first and second teeth of the protibiae and the rounded dorsal edge (external angle) of the mandible. These traits are shared with G. festivus Ménétries, 1836 , G. luristanus Reitter, 1903 , and G. calvaster . In contrast, other Glaphyrus species have an acutely angulate protibial incision (as in Fig. 25 View FIGURES 22–30 ) and an angulate dorsal edge of the mandible, sometimes forming an obtuse tooth (as in Fig. 19 View FIGURES 12–21 ). The distinguishing characteristics of G. calvaster are described above.

Glaphyrus festivus and G. luristanus can be differentiated from G. sabatinellii sp. nov. by their more robust and vertically convex bodies, rougher elytral sculpture with a distinct network of wrinkles, shorter and wider clypeus, and distinctly thicker hind femora in males (as in Fig. 28 View FIGURES 22–30 ).

Distribution. So far known from type locality only.

Etymology. The new species is dedicated to our good friend, well known specialist on Scarabaeoidea Dr. Guido Sabatinelli (Museum d’histoire naturelle de Genève, Switzerland) with our gratitude for his continuous co-operation in our study of Glaphyridae .
