Abstract

Nine Isophya species were studied from the Batı Karadeniz Region of Turkey and one new species, Isophya yaraligozi, described. Distributions, previous records, type material and type depositories are given. A key to the species of the region is provided.

Introduction

The genus Isophya Brunner von Wattenwyl 1878 contains about 80 species, distributed mainly through southeastern Europe, Anatolia and Caucasia. Several species are found from middle Asia, Middle East, middle and southwest Europe (Ramme 1951, Bei-Bienko 1954, Karabağ 1958, Harz 1969, Stolyarov 1997, Heller 1990, Heller et al. 1998). In addition, several Neotropical species [aequatorialis Giglio-Tos, pulchella Giglio-Tos, punchtinervis (Stål), schoenemanni Karsch, brasiliensis Br v. W., melanochloris Rehn] have been placed in this genus (Kirby 1906, Otte & Naskrecki 1997). However, their generic affinity needs confirmation. Forty-six species have been recorded from Europe including Caucasia and the European part of Turkey (Heller et al. 1998). In Turkey, 34 species have been found so far (Ramme 1951; Karabağ 1958, 1962, 1975; Maran 1958; Heller 1988; Demirsoy 1974; Naskrecki & Ünal 1995; Sevgili & Heller 2003).

The Batı Karadeniz (west Black Sea), is one of the 8 geographical regions of Turkey, and includes the provinces of Düzce, Bolu, Zonguldak, Bartın, Karabük, Kastamonu, Sinop, northern parts of Eskişehir, Çankırı and Ankara. The region is bordered by the Sakarya River in the west, Kızılırmak River in the East, the Sündiken and Köroğlu Mts in the south and the Black Sea in the north (Fig. 31). The first orthopteran records, including 2 Isophya species (amplipennis, pavelii), were given from this region by Retowski (1889). The other Isophya species have been recorded from the Batı Karadeniz Region by Ramme (1951), Karabağ (1958, 1964), Karabağ et al. (1980), Maran (1958), Heller (1988), Özdikmen (1994) and Ünal (1999, 2002). Four species (ilkazi, obtusidens, obenbergeri, staneki) have been described from the region by Ramme (1951) and Maran (1958).

The present paper is based on 685 specimens, belonging to 8 species, collected during the last 6 y by the author. In addition, I. obtusidens Ramme, which has not been recorded since its discovery, is discussed. One new species, I. yaraligozi sp.n., is described. A key to the species is provided for the region. Distributions, previous records in Turkey, new illustrations and type depositories are given. In addition, there are 3 maps showing the distributions of the species in the Batı Karadeniz Region.

Type material is deposited in the Abant İzzet Baysal Üniversitesi Entomoloji Müzesi, Bolu, Turkey.

Distribution.— Known from Romania, Bulgaria and NW Turkey. Recorded in Turkey from Tekirdağ, İzmir, Bursa and Bolu provinces. Recorded from the Batı Karadeniz Region by Ünal (2002).

Remarks.— This species exibits minor differences in the shape of the cercus, tegmina, ovipositor and body size between populations from high and low elevations. Highland specimens are smaller than lowland ones. In addition, the male cercus is straighter over the basal 4/5, more curved in the apical 1/5; ratio of male tegmina to pronotum is smaller; the serrated apical part of the ovipositor is narrower in highland specimens. All other features are similar. This is the commonest species of the genus Isophya in the western part of Batı Karadeniz Region. Özdikmen (1994) recorded 2 species, I. schneideri Br v. W. and I. zernovi Miram, from Soğuksu National Park, Kızılcahamam, in Ankara Province. These records are erroneous and the specimens belong rather to I. rectipennis Br v. W.

Isophya obtusidens Ramme, 1951 Isophya obtusidens: Ramme, 1951, Mitt. zool. Mus. Berlin, 27: 167. Fig. 23, 33

Type locality.— Turkey, Çankırı Prov., Kay Dağ. Holotype ♀ in the Natural History Museum London.

Previous records.— Ramme 1951: Çankırı Prov., between Ankara and Çankırı, Kay Dağ, 10-8-1931, 2 ♀♀ (type material), (leg. B.P. Uvarov).

Distribution.— Known only from type locality, NW Anatolia.

Remarks.— Ramme (1951) has described this species on the basis of 2 females collected between the Batı Karadeniz and the Middle Anatolia Regions in Çankırı Prov. According to Ramme I. obtusidens closely resembles I. nervosa, and differs from it only in the blunt apical teeth of the ovipositor (Fig. 23). Bei-Bienko (1954) and Maran (1958) have also cited Ramme (1951). All my specimens collected from that region belong to I. nervosa. There are good images of types of both species in the OSF online (Otte & Naskrecki 1997). The holotype of I. obtusidens Ramme is probably just an older female of I. nervosa. Ramme's type material (2 females) need confirmation.

Pronotum (Figs 28, 29) cylindrical in anterior part, moderately widened in metazona; anterior margin straight, in some males slightly concave; posterior margin convex; sulcus behind middle of pronotal disc; pronotum concave in lateral view, metazona weakly raised (Fig. 29). Tegmina (Figs 28, 29) reaching beyond 2nd abdominal tergite, slightly longer than pronotum; inner margin of left tegmen slightly protruding beyond outer margin of pronotum; stridulatory vein (Cu2) long and thick, as wide as 2nd antennal segment, only 1.26× shorter than hind margin of pronotum. Hind femur unarmed ventrally, in 1 male with 1 small spine at apical part of right hind femur. Ratio pronotum to fore femur— 1:1.2. Supraanal plate with broadly rounded apex (Fig. 27), in one male pentagonal (Fig. 27a); 1.7× broader than long. Cercus (Fig. 7) moderately stout; basal part widened and conical, strongly incurved just beyond middle; in some males cercus more inward curving (Fig. 7a), its apex blunt, with a large subapical tooth. Subgenital plate (Fig. 15) 1.7× longer than wide, strongly narrowed at apex with shallow, round incision; its apical lobes with rounded apices.

Female: Fastigium of vertex as broad or somewhat narrower than antennal scape. Pronotum (Fig. 30) cylindrical, slightly widened in metazona; almost straight in lateral view; anterior margin slightly concave, posterior margin convex in dorsal view. Tegmina (Fig. 30) reaching beyond half of 1st abdominal tergite, almost half of pronotal length; in one female 2.6× shorter than pronotum. Right hind femur with one spine at apical half ventrally, in other females hind femur unarmed. Supraanal plate 2× broader than long, with rounded apex. Cercus conical, slightly incurved at apex; a little longer than supraanal plate. Ovipositor (Fig. 24) relatively long, 2.3× longer than pronotum; ratio ovipositor to hind femur: 1:1.6; lower and upper valves with 6 apical teeth. Gonangulum and basal fold of lower valve as in Fig. 24. Subgenital plate (Fig. 26) distinctly broader than long, with small, round lobe at apex.

Color.— Body various shades of green yellow, reddish-brown and cream. Face light green. Dorsal surface of head, pronotum, hind femora and abdominal tergites with dark spots of various size. Metazona of pronotum with brown bands on both sides. Veins of tegmina dark green except Cu2, area between them greenish-brown; Cu2 cream; costal margin of tegmina with light green band along its length. All legs green; fore and middle tibia with irregular, dark green stripes. Abdomen with 2 light bands along its length, with reddish-brown spots. Ovipositor green and creamy-green; its apical teeth reddish-brown.

Measurements (mm).— Length of body: ♂ 20.7 to 23.1, ♀ 22 to 24; pronotum: ♂ 4.6 to 5, ♀ 5 to 5.2; tegmen: ♂ 5.2 to 5.7, ♀ 2 to 2.6; hind femur: ♂ 17 to 18.1, ♀ 17.8 to 19; ovipositor: 11.1 to 11.6.

Diagnosis.— This new species is distinguished from known related species in the genus Isophya Bei-Bienko by its broad fastigium vertictis, nearly as broad as or slightly broader than the antennal scape, by the male cercus with its larger subapical denticle that always protrudes beyond the cercal apex, by the longer or thicker stridulatory vein, the smaller size and the shorter ovipositor.

Other similarities and differences are as follows: this new species belongs to the I. modesta Frivaldsky group (see Bei-Bienko 1954). It is closely related to I. obtusa Br v. W. 1882 from Yugoslavia, Romania and Bulgaria by measurements of its ovipositor and hind femur, by the ratio of pronotum to ovipositor (1:2.3 to 1:2.5 in I. obtusa) and the general shape of the male cercus. But differs from it in pronotal shape, pronotum with convex hind margin, less concave in lateral view and in the shape of the male supraanal plate. It is also near to I. modesta Frivaldsky 1867 from the Western Balkans, but differs from it by the shape of the male cercus, supraanal plate, the measurements, the thicker stridulatory vein, and the shape of male subgenital plate. It differs from I. rossica Bei-Bienko 1951 from Ukraine by the shape of the pronotum, female subgenital plate, and by the measurements. From I. rhodopensis Ramme 1951 from Bulgaria by the longer stridulatory vein, the shape of the male cercus and the supraanal plate. Differs from I. modestior Br v. W., 1882 from Balkans and I. costata Br v. W. 1878 from Middle and Eastern Europe by the shape of the male cercus, subgenital plate, and supraanal plate, by the ratio of male pronotum to tegmina; the tegmina is always longer than the pronotum in the new species. In I. costata, the width of the fastigium of vertex is as in the new species. I. yaraligozi differs from I. bureschi Peschev 1959 of Bulgaria by having a longer stridulatory vein and by the shape of the supraanal plate. From I. petkovi Peschev 1959 also from Bulgaria it differs by the shape of supraanal plate, the smaller size, and the shorter ovipositor. It differs from I. kisi Peschev 1981 from Bulgaria by the shape of pronotum, tegmina, cercus and supraanal plate.

Type Material.— Kastamonu Prov., Devrekani, Yaralıgöz Dağı, 1450 m, 17-7-2002, 3 ♂♂, 3 ♀♀; Esentepe, 1450 m, 17-7-2002, 1 ♂ (leg. S. Ünal & M. Ünal).

Etymology.— The specific epithet is derived from “Yaralıgöz” Mountain, the type locality of this new species.

Habitat.— Open area within Abies nordmanniana and Pinus sylvestris forest.
