description: 3.2. Chaetopteryx sinopica Sp.n. (Figures 3 and 4)
Material. Holotype male and paratypes (4 males, 2 females): Turkey, Sinop, Küre Mountains, Boyabat, Bürnük (CD: R-1248), 41 ◦ 39 N, 34 ◦ 51 E, 1146 m, 2.x.2009; other paratypes: Sinop, Hanönü, Akgöl, Çangal Mountain (CD: R-1250), 3.x.2009, 3 males, 2 females; same places, 41 ◦ 41 N, 34 ◦ 34 E, 1130 m (CD: R-1261), 26.x.2009, 1 male, 1 female; Sinop, Dikmen, Durağan direction, Küre Mountains, 41 ◦ 31 N, 35 ◦ 09 E, 917 m, (CD: R-1265), 25.x.2009, 2 males, 2 females; leg and coll. Sipahiler.
Scapus pale brown, other segments of the antennae dark brown; palps and legs pale brown, wings brown; spur formula of male is 0.3.3, of female 1.3.3. Length of the anterior wing of males 10-11 mm, of females 12-13 mm.
Male Genitalia (Figure 3). In dorsal view, spinulose zone of tergite VIII is large, almost oval, with sides dilated; in lateral view, anterior edge and dorsolateral part of segment IX strongly sclerotized; dorsal cavity rather large, with preanal appendage small; in caudal view, preanal appendages rounded, ventral parts becoming narrower, forming a petiole. In lateral view, intermediate appendage is broad and rather short, dorsal edge slightly dilated, and ventral edge roundly dilated; apical portion becoming narrower and quadrangular. In dorsal view, triangular with apex curved on sides. In lateral view, inferior appendage is long, curving inside; outer portion with long hairs. In caudal view, apical part is short, strongly sclerotized, almost quadrangular. Supra-anal plate is narrow, weakly sclerotized; apical part slightly rounded. In lateral view, the phallic apparatus is curved dorsally. In ventral view, apical part as broad as basal portion; apical edge roundly excised in the middle, with a small membranous part, sides are straight. Apex with sclerotized thick spine on each side, the shaft with long and thin sclerotized bands. Parameres dilated subdistally and each bears six spines, of which the outer one is thicker than the others.
Female Genitalia (Figure 4). In dorsal view, dorsal part of segment IX broadly and roundly excised, forming two triangular lobes on each side; covering the cavity of segment X. The ventral part is trapezoidal, with apical margin very short and smooth, bearing two long spines on each corner. In lateral view, ventral margin of tube-like part of segment X is pointed at the tip and as long as side lobes of segment IX. In caudal view, median lobe of the vulvar scale is large, with apex rounded.
Remarks. Chaetopteryx sinopica sp.n is closely related to C. nalanae Sipahiler, 1996, described from Bolu province in northwestern Turkey [1]. The following differences exist in the male genitalia: in C. nalanae, in dorsal view, the spinulose zone of tergite VIII is nearly trapezoidal, the apical and lateral edges are straight, the preanal appendages are broadly rounded and without petioles on the ventral parts, the intermediate appendages are long and narrow, the phallic apparatus very large on the apical portion, of which the sides are rounded, and the parameres are broad on the distal portion. In the new species, the spinulose zone is almost elliptical; at the preanal appendages, petioles are present ventrally, and the intermediate appendages are short and broad. Quadrangular projections are protruding apically, apical part of the phallic apparatus narrow, and the sides straight and the parameres distally narrow. The differences in the female genitalia are as follows: in C. nalanae, in dorsal view, the side lobes of segment IX are rounded, the ventral part of segment X is long, almost quadrangular, and the apical margin slightly excised. In the new species the side lobes of segment IX are triangular, the ventral part of segment X is as long as the side lobes and trapezoidal. The apical edge is very short, bearing two long setae, and, in lateral view, it is pointed at the tip.
Etymology. Named after the place where the type specimens were collected.
