Vulda cangalica sp. n.

( Figs. 7–13 )

Type material. Holotype: ɗ, "Cangaldagh, Anat. bor. 16.–26.V.57, leg. F. Schubert / Xantholinus spec.? det. F. Schubert / Holotypus ɗ Vulda cangalica sp. n. det. V. Assing 2006" ( NHMW). Paratypes: 1ɗ, same data as holotype ( NHMW); 1ɗ, "Anat. b. Cangal Dagh, 7.– 15.6.60, leg. F. Schubert" ( NHMW); 1ɗ, "Cangal/ Ayancik, 5.62, Anat., leg. F. Schubert" (cAss).

Description. Measurements (in mm) and ratios (range, arithmetic mean; n=4): AL: 2.32–2.44, 2.39; HL: 1.59–1.68, 1.62; HW: 1.10–1.21, 1.16; PW: 0.95–1.01, 0.97; PL: 1.51–1.59, 1.53; EL: 0.95–1.06, 1.01; EW: 1.15–1.28, 1.22; AW: 1.10–1.25, 1.17; TiL: 0.95–1.01, 0.99; TaL: 0.77–0.83, 0.79; ML: 1.30–1.39, 1.33; TL: 8.6–9.4, 9.9; HL/HW: 1.36–1.45, 1.39; PW/HW: 0.81–0.86, 0.83; PL/PW: 1.57–1.60, 1.59; EL/PL: 0.64– 0.67, 0.66; EW/PW: 1.21–1.30, 1.26; AW/EW: 0.95–0.98, 0.96; TiL/TaL: 1.22–1.27, 1.25.

Habitus as in Fig. 7 . Coloration: blackish brown to black; pronotum reddish brown to castaneous; elytra yellowish to yellowish brown; abdomen reddish to dark brown, with the posterior margins of the anterior segments and the abdominal apex reddish; legs reddish to brown; antennae reddish brown to brown.

Head distinctly oblong (see measurements and ratio HL/HW); lateral margins weakly convex in dorsal view ( Fig. 9 ); eyes small ( Fig. 10 ), not projecting from lateral outline of head, 1/7–1/5 the length of postocular region in dorsal view; dorsal surface with well-defined and moderately coarse puncturation, at most with very scattered micropunctures; microsculpture absent. Antenna with antennomere I approximately as long as the combined length of antennomeres II–V; II and III oblong and of subequal length; IV weakly transverse; V–X weakly to moderately transverse; X less than 1.5 times as wide as long.

Pronotum slender, distinctly narrower than head (see ratio PW/HW), moderately tapering posteriad; lateral margins almost straight in dorsal view; dorsal series somewhat irregular, composed of 10–13 punctures; whole surface with very sparse micropunctures, lateral areas with sparse coarse punctures; microsculpture absent ( Fig. 8 ).

Elytra distinctly shorter and wider than pronotum (see ratios EL/PL and EW/PW); puncturation welldefined and of variable density ( Fig. 8 ). Hind wings completely reduced. Legs moderately slender (see measurements and ratio TiL/TaL).

Abdomen approximately as wide as elytra, widest at segments VI/VII; puncturation fine, much sparser on posterior than on anterior tergites; posterior margin of tergite VII without palisade fringe.

ɗ: aedeagus with internal structures of distinctive shape ( Figs. 11–12 ).

Comparative notes. The species is distinguished from all its congeners by the distinctive morphology of the aedeagus. From other species occurring in Turkey, it is additionally separated as follows: from V. o t t o m a n a by larger size; from V. brignolii by the bicoloured body, as well as by the more slender head and pronotum; and from V. vignai by distinctly smaller size and by larger eyes.

For illustrations of the habitus and genitalia of these species see Figs. 5–6 and 14–15 , as well as Bordoni (1973a).

Etymology. The name refers to the mountain range where the type specimens were discovered.

Distribution and bionomics. The known distribution is confined to the Çangal Daġı, Sinop province, northern Anatolia. Additional bionomic data are not available.

FIGURE 13. Distribution of the genus Vulda in Turkey: V. ottomana (Cameron) (filled circles), V. vignai Bordoni (open circle), V. cangalica sp. n. (filled squares), and V. brignolii Bordoni (open square). Since the type locality of V. brignolii (" Boraby gölü ") was not identified (misspelling?), the respective square is placed in the centre of Amasya province.
