Eremocharis subsulcata beccalonii Ünal , ssp. nov.

( Figs. 14 , 114 , 180–186 , 839 )

Type locality. Pakistan: Between Nushki and Quetta. Holotype: male (NHMUK).

Material examined. PAKISTAN: W. Pakistan, between Nushki and Quetta, 4.6.1963, 1♂ (Holotype), 5♀ ; W. Pakistan, between Quetta and Mastung, 13.6.1963, 1♀; W . Pakistan, Baluchistan, nr. Quetta , 4.6.1963, 1♂, 4♀ (all leg. G. B. Popov) ( NHMUK).

Description. Male (Holotype): Body slightly compressed laterally, dorsal surface flat, like a rectangular prism ( Fig. 180 ). Preocellar foveola with irregular margins, slightly larger than lateral ocellus; supraocellar foveola weak, narrowly oval; supraocular foveola absent. Fastigium of vertex ( Fig. 182 ) concave, with slightly raised lateral margins. Vertex between the eyes 1.1 times narrower than vertical diameter and as wide as transversal diameter of eye; median carinula weak, grooved. Eye wide, almost rounded, 1.1 times longer than wide. Frontal ridge with parallel lateral carinae between the antennal scapes, strongly incised just below the median ocellus, then lateral carinae combined and ended before the clypeus. Antennae lost. Prozona of pronotum ( Figs. 182 , 184 ) slightly raised, weakly roof-shaped, intersected by 2 transversal sulci; metazona ( Figs. 182 , 184 ) flattened, very long, 2.1 times longer than prozona and 1.1 times longer than its width, posterolateral margins slightly raised and thickened with large tubercles, preapical part distinctly depressed; median carina grooved in prozona and anterior part of metazona; anterior margin of pronotum convex, posterior margin sharp, acute angular. Prosternum with very slightly raised, carinate anterior margin. Mesosternal interspace 1.7 times wider than its length and 1.7 times wider than mesosternal lobes. Tegmina ( Fig. 180 ) long surpassing the half of hind tibia, 4.3 times longer than wide. Hind wing ( Fig. 180 ) mainly green, slightly bluish-green in basal part, with a distinct narrow dark (brown) median band, strongly incurved at posterior margin, reaching to inner margin, apical lobes transparent, without dark spot and not infumated. Mid femur, hind femur and tibia strongly hairy ( Fig. 183 ). Hind femur strongly tuberculated, 3.1 times longer than its height, dorsal and ventral margins undulate with distinct large tubercles; preapical narrowing (2.8 mm) distinct, genicular lobes 3.8 mm. Hind tibia with 9 inner, 9–10 outer spines, dorsal surface very densely hairy (it is not easy to see the inner spines in lateral view of proximal part from the outer side because of the dense hairs). Subtympanal lobe covering 1/3 of tympanum. Arolium very narrow and small, reaching to 1/3 of claws. Phallus ( Figs. 14 a, b) short and high; apical valves of penis tubular in basal part, strongly compressed antero-posteriorly, posterior surface flattened and heart-shaped at apex ( Fig. 14 d); dorsal valves of cingulum narrowly rounded at apex; tumida of zygoma wide and weakly swollen; tumida of cingulum large, elongated diagonally from tumida of zygoma to ventral margin of the sheath of penis ( Fig. 14 a); apodemes and basal valves of penis short and broad; epiphallus broad and short, posteromedian projection with staright hind margin, pseudolophi elongated with 14 spines ( Fig. 14 c).

Female: Body as in male, but larger ( Fig. 181 ). Preocellar foveola weaker. Vertex between the eyes broad, 1.12 times wider than vertical diameter and 1.3 times wider than transversal diameter of eye. Eye broad, 1.2 times longer than wide. Metazona of pronotum ( Fig. 185 ) very long, 2.05 times longer than prozona and very slightly (1.02 times) longer than its width, with less tubercles than that of male. Mesosternal interspace almost 2 times wider than its length and 1.5 times wider than mesosternal lobes. Tegmina ( Fig. 181 ) 3.9 times longer than wide, regularly narrowing towards apex. Hind wings ( Fig. 181 ) green in basal disc, with a narrow and long median dark band similarly in male, in one female from Quetta with weaker median band. Hind femur 3.25 times longer than its height, its shape and structure as in male. Hind tibia with 9 inner, 10 outer spines. Mid femur, hind femur and tibia strongly hairy ( Fig. 186 ). Subtympanal lobe covering slightly more than 1/3 of tympanum ( Fig. 114 ). Subgenital plate distinctly longer than wide, posterior margin with a median projection.

Coloration. Body unicolor creamish-milky brown, with weak small brown spots. Eye light brown. Head and pronotum with light cream tipped tubercles. Tegmina with many short brown stripes along longitudinal veins. Basal disc of hind wing green, slightly bluish-green with a narrow and long brown band strongly incurved at posterior margin. Inner and ventral surface of hind femur completely body color, with a small blue spot on inner side of ventral genicular lobe; dorsal and ventral margins with long and dense white hairs. Inner and dorsal surfaces of hind tibia yellowish-cream, inner spines with dark brown inner side, outer sides and outer spines yellowishcream, inner side of basal end of tibia with a blue spot; dorsal surface with long and dense hairs. Tarsus yellowishcream. All sternites cream.

Diagnosis. This new subspecies is distinguished from the all known subspecies of E. subsulcata (Stål) and E. maior Ramme by the green basal disc of hind wing (yellow in the others or greenish-yellow in E. maior ), the strongly hairy hind legs (distinctly less hairy in the others); their distribution does not overlap. It is different from E. maior Ramme by the green basal disc of wing (greenish-yellow in E. maior ), the strongly hairy hind legs; the metazona, more than 2 times longer than prozona and longer than its width (1.6 times longer than prozona and slightly shorter than its width in E. maior ), the larger body size and distribution. It is different from E. subsulcata povolnyi ( Cejchan, 1969) by the green basal disc (sulphur yellow in E. s. povolnyi ), the strongly hairy hind legs, the longer metazona (1.9 times longer in male and 1.3–1.5 times longer in female of E. s. povolnyi ), the acute angular posterior margin of pronotum (narrowly rounded in E. s. povolnyi ). If differs from E. s. subsulcata (Stål) and E. s. atripes Bey-Bienko by the green basal disc of wings (sulphur yellow in these 2 species), the narrower median dark band of wings, strongly hairy hind legs, the blackened inner spines of hind tibia (not darkened in E. s. subsulcata ) and the shorter tegmina, slightly surpassing the half of hind tibia (reaching the apex of hind tibia in E. s. subsulcata and E. s. atripes ). It is distinguished from E. s. rosacea Bey-Bienko, 1963 by the green basal disc of wing (yellow in E. s. rosacea ), the yellowish-cream hind leg color (inner surfaces of hind femur and tibia light rose in E. s. rosacea ), the longer metazona (1.8 times longer than prozona in the paratype of E. s. rosacea ), the shorter tegmina (reaching the apex of hind tibia in E. s. rosacea ). This new subspecies is the only member of the species E. subsulcata in Pakistan.

Measurements (mm). Holotype (male): body length 42.3; pronotum length 13.9 (prozona 4.5, metazona 9.4); pronotum height 8.2; tegmina length 37.3; tegmina width 8.6; hind femur length 18.9; hind femur height 6.1. Paratypes: body length: female 54.4–58.3; pronotum length: female 16.8 (prozona 5.5, metazona 11.3)–17.8; pronotum height: female 10.6–11.4; tegmina length: female 43.7–48; tegmina width: female 11.3–12.3; hind femur length: female 22.6–24.4; hind femur height: female 7.5–8.

Etymology. This large sized new subspecies is dedicated to Dr. George Beccaloni (NHMUK London) for his support this long term study and hospitality during my visits the NHMUK as well as his interest to the large insects.
