Isophya bozlak Ünal, sp. nov.

( Figs. 33–46 )

Type locality. Turkey: Çorum Prov., Ortaköy Distr. , Oruçpınar Vill., 1100 m .

Description. Male (Holotype). Fastigium of vertex ( Fig. 33 ) wide, 1.3 times narrower than antennal scape, lateral margins almost parallel, rounded at apex, with a distinct dorsal fossa. Pronotum ( Figs. 34, 35 ) cylindrical in prozona, slightly widened and flattened in metazona; dorsal surface smooth and straight, very weakly raised in metazona; anterior margin straight, posterior margin slightly convex in dorsal view. Tegmina ( Figs. 34, 35 ) 1.3 times longer than pronotum, reaching slightly beyond second abdominal tergite; as wide as posterior margin of pronotum at visible base, gradually widened backwards in dorsal view; CuP thin, 1/4 shorter than posterior margin of pronotum. Hind femur without ventral spines. Supra anal plate 1.25 times wider than long, rounded at hind margin. Cercus ( Fig. 38 ) slender, basal 3/4 part weakly and gradually incurved and narrowed; apical part more strongly and somewhat gradually incurved and narrowed, pointed at apex with a distinct, narrow triangular apical denticle, which in accordance with the apical constriction, like the tip of a pencil; apical incurved part not upcurved in posterior view. Subgenital plate ( Fig. 39 ) 1.7 times longer than wide; distal part bent upwards along its length under an obtuse angle in lateral view; reaching beyond the half length of cercus ( Fig. 37 ); ventral surface with two longitudinal swellings just behind the apical lobes; with a tongue shaped posterior incision and 2 apical lobes with same size and shape of posterior incision; in some paratype posterior lobes and incision more triangular than that of holotype.

Female (Allotype). Fastigium of vertex ( Fig. 40 ) wide, almost as wide as antennal scape; elliptical, but rounded at apex, with a dorsal fossa. Pronotum ( Figs. 43, 44 ) almost cylindrical, weakly widened in metazona; dorsal margin straight in lateral view; anterior margin weakly concave, posterior margin slightly convex. Tegmina ( Figs. 43, 44 ) slightly wider than posterior margin of pronotum in dorsal view; reaching just beyond the half of the first abdominal tergite; each tegmen broadly rounded at hind margin; twice as short as pronotum. Hind femur without ventral spines. Supra anal 1.5 times wider than long, narrowly rounded at hind margin. Cercus simple, long conical, slightly incurved along its length, and weakly longer than supra anal plate. Subgenital plate ( Fig. 45 ) short and wide, 3 times wider than long, rounded along its hind margin, but with a blunt, tongue-shaped projection in the middle; in some paratypes subgenital plate more triangular. Ovipositor ( Fig. 46 ) 2.2 times longer than pronotum, moderately upcurved along its length, with 8 upper and 6 lower apical teeth; in paratypes, upper and lower valves with 6–8 apical teeth; posterior margin of gonangulum with a small, more or less distinct incision in the middle of the lower half.

Colouration. In dry specimens, green colour mostly replaced with creamish milky-brown. Body green with black, cream and reddish spots, bands and stains. Face greenish cream. Antennae light brown. Dorsal surface of head, pronotum, all legs, abdomen with brown and black small spots; a typical marble-white band lies from behind the eye to the end of tegmina laterally. Pronotum with a median thin light stripe along its length in dorsal view. Tegmina green with lighter veins. Abdomen with 2 parallel longitudinal light bands along its length, these more distinct in males. Subgenital plate and ovipositor green; serrated part of ovipositor dark green, tips of apical teeth black.

Discussion. This new species is a member of the I. rectipennis sp. group as suggested by the width of the fastigium of vertex, the shapes of pronotum and tegmina and the length and curvature of ovipositor. It is most closely related to I. rectipennis but differs from it by the shape of male cercus [in I. rectipennis , cercus straighter ( Fig. 3 of Ünal 2003), apical fifth more sharply incurved and pointed with a sharper apical denticle; apical incurved part also upcurved in posterior view], the longer male subgenital plate [in I. rectipennis ( Fig. 11 of Ünal 2003) distinctly shorter, reaching at most 1/3 of cercus], the wider fastigium of vertex, the thinner CuP, the longer and less upcurved ovipositor, the shape of gonangulum [in I. rectipennis ( Fig. 19 of Ünal 2003) gonangulum mainly concave at posterior margin and posterior notch at the base].

Isophya bozlak differs from I. pavelii by the shape of male cercus [In I. pavelii , cercus ( Fig. 2 of Ünal 2003) gently incurved along its length with a very distinct, sharp, longer, separated and slightly incurved apical denticle), the narrower fastigium of vertex (In I. pavelii slightly wider than scapus), the shape of gonangulum (compare Fig. 46 with Fig. 18 of Ünal 2003), the thinner and less distinct CuP (In I. pavelii , CuP typically very distinct and wider near to costal side than remaining part).

Isophya bozlak is also similar to I. ilkazi . It differs from it by the shape of male cercus [In I. ilkazi , cercus ( Fig. 5 of Ünal 2003) clearly stouter, with a more distinct, separated and incurved apical denticle), the less distinct, thinner and longer CuP (In I. ilkazi very distinct, wide and short), the longer and straighter ovipositor [In I. ilkazi , ovipositor clearly short and more upcurved), the shape of gonangulum (In I. ilkazi , regularly D-shaped, without posterior notch).

The general appearance of Isophya bozlak is also similar to I. nervosa , I. stenocauda , and I. obenbergeri . But this new species is easily separated from them by the shape of male cercus which bears a single apical denticle (in these species cercus more or less carinate apex), the wider fastigium of vertex, the shape of gonangulum.

Etymology. “Bozlak” is a genre of slow Turkish folk music characterized by melancholic, sorrowful, and heartwrenching songs. It originates from the central and northern parts of Central Anatolia, particularly the provinces of KırŞehir, Kırıkkale, Çorum, and Yozgat. This new species is found in almost the same region of Turkey.

Remarks. The morphological differences between some species can only be seen when compared, together with related species, as in this new species. Otherwise, this species can easily be confused with other species. The genus Isophya usually includes such similar species. This new species was compared to all related species, with large collections including the type specimens in the collections of AİBÜEM, NMW, MfN, and ZIN. A male from Kırıkkale Province was previously given as Isophya schneideri by the author ( Ünal 2005: 429; Ünal 2006b: 6), which belongs to this new species.
