Sarcophaga (Heteronychia) anatolica sp. nov.

( Figs 6–11 )

Type material. Holotype 3: TURKEY: ANKARA / 25km S, Beynam Forest / 1450m, 7.v.1993 / V. Michelsen – Coll. ZMUC // [red label] HOLOTYPE 3 / Sarcophaga / ( Heteronychia ) / anatolica sp. n. / det. D. Whitmore 2010 ( ZMUC). Paratypes: 2 3: Turkey, Nevsehir, Avanos, Ürgüp area, 1000m, 4–6.V.1993, V. Michelsen leg. ( ZMUC).

Diagnosis (3). A small species of Heteronychia with long antennae, arista thickened on basal half or more and wide frons; frons protruding in lateral view; lower facial margin not visible in lateral view; scutellum with a pair of apical setae; wing vein R1 with a few setulae on dorsal surface; abdomen with dense grey microtrichosity covering most of tergites in posterior view; abdominal tergite 3 without median marginal setae; epandrium dark red or black; cercus with a lateral bare patch in upper half; distiphallus short, globular; juxta short with small, rounded basal processes; median part of juxta wide.

Description (3). Length. 5.0–6.0mm. Colour. Ground colour black, with grey microtrichosity on parafacials, fronto-orbital plate, thorax and abdomen. Thorax with three longitudinal dark vittae; microtrichosity of abdomen dense: in posterior view covering most of tergites 3–5 apart from a central dark strip (wide on T3–4, narrow on T5) and two dark lateral spots on posterior part of tergites. Protandrial segment shiny black, with at most a very small central patch of microtrichosity on posterior edge; epandrium dark red or black. Cercus shiny black; surstylus, phallus and gonites dark brown. Head ( Fig. 6 ). Arista thickened on approximately basal 1/2–3/5. Postpedicel about 2.5 times as long as pedicel. Frons at its narrowest point about 0.7 times the width of an eye in dorsal view. Lateral vertical setae distinctly longer and stronger than longest postocular setae. Parafacial at its narrowest point about 1/ 5–1/4 of eye width. Lower facial margin not visible in lateral view. Gena in profile 0.25–0.40 times height of eye; postgena entirely covered with white setulae (at most with a few darker setulae anteriorly). Occipital setulae white below the first two rows. Thorax. Scutum with 2 (unarranged) + 0–1 (weak) acrostichal, 4 + 3 dorsocentral, 1 posthumeral, 1 presutural, 4 notopleural, 2 intraalar and 3 supraalar setae. Scutellum with a pair of apical setae; discal setae weak, situated far from margin. Legs. Mid-femur without a subapical posteroventral comb. Mid tibia with 3 anterodorsal, 2 posterodorsal, 1 dorsal and 1 anteroventral setae. Hind trochanter with a ventral brush of spine-like setae. Hind femur with a few weak anteroventral setae in addition to subapical one. Hind tibia with 2 anteroventral setae; hind tibia without long, wavy setulae on posteroventral surface. Wing. Costal spine strongly developed. Vein R1 with 1–3 setulae on dorsal surface. Second costal section about the same length as fourth costal section. Abdomen. Tergite 3 without median marginal setae. Terminalia. Setae on sternite 5 thickened and shortened, marginal ones only slightly longer. Protandrial segment with a row of setulae along posterior margin. Epandrium with an elongated ventral margin. Cercus ( Fig. 7 ) with a rounded subapical hump and sharply pointed tip, without a dorsal excavation and with a lateral bare patch in upper half extending to level of apex of surstylus. Surstylus ( Fig. 7 ) subtriangular. Pregonite ( Fig. 8 ) with short, sparse setulae almost reaching tip, and with a distinct subapical twist; tip blunt, slightly bent ventrally. Distiphallus ( Fig. 9 ): proximal part of harpes rounded in lateral view, with a concave inner surface and continuous with distal part; apical process flattened, tapering and directed more or less ventrally; juxta short with small, rounded basal processes; median part of juxta ( Fig. 10 ) wide, with a pair of well-developed lateral processes and a small median triangular process; vesica ( Fig. 11 ) subrectangular, flat, with pointed corners.

Female unknown.

Distribution. Asiatic Turkey.

Etymology. A Latin adjective referring to Anatolia, another name for Asiatic Turkey.

Differential diagnosis. Sarcophaga (Heteronychia) anatolica sp. nov. shows affinities with members of the ancilla -group, such as the elongated postpedicel, the wide, protruding frons, the abdominal pattern of microtrichosity, the short, globular distiphallus and the structure of the juxta. It can be distinguished from other species of this group by the conspicuous basal thickening of the arista, the shape of the cercus, the distribution of setae on the cercus, and the wider median part of juxta.
