A new species of the genus Phytoecia Dejean, 1835 from Muş province (Eastern Turkey) is described. For this species a separate subgenus is established. Резюме. Описан новый вид рода Phytoecia Dejean, 1835 из провинции Муш в Восточной Турции. Для этого вида установлен отдельный подрод. As a result of the author’s field research in Eastern Turkey in 2011 a new species of the genus Phytoecia Dejean, 1835 was collected, that is described here. Since this species is very different from the other species of Phytoecia s. l., based on the complex of characters it is placed in a separate subgenus. Metallidia subgen. n. Type species: Phytoecia alinae sp. n. According to some modern opinions [Catalogue of Palearctic Coleoptera, 2010; Sama et al., 2010a; Sama et al., 2010b], some of the subgenera of the genus Phytoecia Dejean, 1835, including Coptosia Fairmaire, 1864 and Pilemia Fairmaire, 1864, receive the rank of separate genera. But, until the final clarification of the taxonomic structure of Phytoecia s. l., in this article, these taxa are considered as subgenera. At the same time, a new subgenus is here described that is very similar to Coptosia, but well differs from it the following characters: metallic green coloration of the body; light dense pubescence of thin long hairs, hiding cuticle on head and pronotum; unicoloured pubescence of body; epipleura with long white hairs; absence thick dark erect setae on elytrae, pronotum and head; short genae, not coarse puncturation of elytra; not granulated side of pronotum; characteristic form of elytral apex; very long mandibles; three dentes on sternites. Also, the new subgenus differs in the structure of the aedeagus: endophallus without basic-latero-ventral sclerites (BLV) (Color plate 6: fig. fig. 5), which always present in Coptosia (Color plate 6: fig. 6) fig. 6). The subgenus Barbarina Sama, 2010 is also characterized by the absence of BLV-sclerites. The new subgenus differs from it by uniform recumbent pubescence of elytra, short genae, long mandibles, absence of dark long setae on head and pronotum, presence of dentes on sternites and dorsal and apical sclerites of endophallus. Light unicoloured pubescence of elytra, pronotum and head is known in Phytoecia (Coptosia) antoniae (Reitter, 1889), but that species is not closely related to Metallidia subgen. n. Metallic glance of the cuticle, form of body and several dentes on sternites make this new subgenus close to the species of Pilemia, from which it is different by the absence of tooth on apex of mandibules and by uniform (nonspotted) pubescence of elytra. Phytoecia (Metallidia) alinae sp. n. (Color plate 5, 6: fig. 1–5, 7–8) Material. Holotype, ♂ – Turkey, Muş prov., near Buglan Gečidi, on Rindera albida, 29–30.05.2011, leg. D. Kasatkin. Paratype – 1♀ with the same label (all types in author’s collection). In addition, I have fragments of one male which was found in the root zone of host plants. Characters of this specimen was used to describe, but it is not included in the type series. Description. Body length of male 12 mm, width – 3 mm; body length of female 12.5 mm, width – 3.5 mm. Entirely metallic green or green-blue. Head densely covered with long erected thin white hairs, densely puncturated, with well-developed microsculpture; very short genae; mandibles very elongate, without tooth. Eyes large, distinctly protruding. Antennae of male reaching the last quarter, of female – the last third of the elytra, evenly covered with dense thin gray hairs, and their 3rd segment slightly longer than 5th and is approximately equal to the 1st and 4th. Pronotum slightly longitudinal or square, with weak constriction in apical part; covered with thin erected white hairs, almost hiding the sculpture. Pronotal punctation not coarse moderately dense, with distinct microsculpture. Elytra elongate (2.75 times longer than wide at base in male, 2.57 in female), much wider at shoulders than at apex, with two obliterate carinae on the disc (humeral carinae distinct in apical part); impressed near shoulders and convex along middle; obliquely truncated on apex, outer angle noticeably elongated (in female – acuminate); covered white-grayish pubescence, faintly hides sculpture, thicker on the carinae and forming indistinct longitudinal stripes; punctation not coarse, shallow and not dense; with long white erect hairs along epipleura, and with single short erect hairs on base. Scutellum strongly transverse, widely rounded. Ventral side of the body covered with dense thick gray-white pubescence, hiding the cuticle. Pygidium long, rounded at apex, postpygidium almost straight cut. Each of 1–3 abdominal sternites of male with one short distinct dens (fig. 3). Legs with dense graywhite hairs; last segment of tarsi longer than 2nd and 3rd. Hind coxae of male without spines. © CAUCASIAN ENTOMOLOGICAL BULL. 2011 Кавказский энтомол. бюллетень 7(2): 143−144
