Turkanocaracris davisi Ünal , sp. nov.

( Figs. 80 , 739–742 , 846 )

Type locality. Turkey: Van , Çatak , Kavuşşahap Dağları. Holotype: male ( NHMUK).

Material examined. TURKEY: Van Prov., Satak [ Çatak ] dist., Kavuşşahap Dağ , 3000 m, 23.7.1954, 1♂ (Holotype) (leg. P. H. Davis) ( NHMUK).

Description. Male (Holotype): Body ( Figs. 741, 742 ) strongly depressed dorso-ventrally. Fastigium of vertex flat, strongly sloping. Frontal ridge not widened, almost parallel sides in the middle part. Vertex completely smooth, without carinulae, tubercles and grooves; foveolae absent; vertex between the eyes as wide as vertical diameter and 1.1 times wider than transversal diameter of eye. Eye broad, 1.1 times longer than wide. Antennae with 13–14 segments. Pronotum ( Figs. 741, 742 ) cylindrical, with small tubercles, without lateral carinae; median cerina weak, not raised, with indistinct longitudinal sulcus; anterior margin straight, posterior margin slightly concave. Prosternum ( Fig. 740 ) almost straight, very slightly raised, wide weakly convex, without any projection. Mesosternal interspace 2.5 times wider than its length and as wide as mesosternal lobes. Hind femur ( Fig. 741 ) narrow, almost 3 times longer than its height, dorsal and ventral margins slightly convex, dorsal margin smooth. Hind tibia with 9 inner, 10 outer spines. Median carinae of mesonotum, metanotum and abdominal tergites ( Figs.

741, 742) very weak, not raised; lateral carinae absent. Tympanum absent ( Fig. 739 ). Arch of zygoma strongly raised, higher than posterior lobes of zygoma; tumida of zygoma visible with very small tubercles; apodemes slightly widened, with apical notch; basal valves of penis narrow and short ( Figs. 80 a, b); pseudolophi ( Fig. 80 c) with 6–7 spines.

Female: Unknown.

Coloration. Body greyish, creamish-brown with black and cream pattern. Gena, behind of eyes and posterior part of vertex cream and creamish straw brown; both sides of frontal groove black; eyes brown. Pronotum, mesonotum, metanotum and first abdominal tergite greyish-brown with distinct black tubercles. Typical light bands on paranota absent. Typical light band on abdomen light creamish brown; lateral surface of abdomen blackishbrown. Fore and mid legs partly cream or yellowish-brown. Outer surface of hind femur greyish; inner and ventral surfaces reddish-black, ventral margin of inner surface dark red basally, dorsal margin yellowish; inner margin of ventral surface dark bright red basally. Outer surface of hind tibia pale dark yellow; inner surface of hind tibia bright red-orange including spines, outer half of dorsal surface turning to orange-yellow. Tarsus red. Sternites pale yellow, darkened with brown stains.

Diagnosis. The only related species is T. levigatus sp. nov. This new species is different from T. levigatus by the red-orange tibia (black in the male of T. levigatus ), the presence of tumida of zygoma (absent in T. levigatus ), the more sloping fastigium of vertex, the narrower frontal ridge with almost parallel sides (wider and distinctly divergent in T. levigatus ) and the absence of tympanum (with a strongly reduced tympanum, smaller than the neighbour stigmal area in T. levigatus ).

Measurements (mm). Holotype (male): body length 21.8; pronotum length 4.2; pronotum height 4.1; pronotum width anterior 4.7; pronotum width posterior 6; hind femur length 8.9; hind femur height 3.

Etymology. This new species is named in memory of the botanist, author and editor of the Flora of Turkey Peter H. Davis who collected many new Orthoptera including extremely interesting Pamphagidae during his field trips in Turkey.
