status

sp. nov.

Microhoria impavida Kejval , sp. nov. ( Fig. 108 View Figs 105–111. 105 )

Type locality. Turkey, Balıkesir Province, Susurluk env.

Type material. HOLOTYPE:, ‘ TURKEY occ., Susurluk env., 27.v.1996, P. Kresl lgt. [p]’ ( NMPC) . PARATYPES: 1 6 ♀♀, same data as holotype ( ZKDC).

Description. Male (holotype). Body length 2.5 mm. Head and pronotum black, elytra brownish-black; legs brown, tibiae slightly paler; antennae brownish-black.

Head 1.2 times as long as wide, widely rounded posteriorly; eyes small, only moderately convex. Surface glossy, densely, rather coarsely punctatate; punctures distinctly spaced; setation short, subdecumbent. Antennae slightly enlarged for apical third; antennomeres X 1.1 times, XI 2.4 times as long as wide.

Pronotum 1.1 times as long as wide, narrower than head including eyes, rounded anteriorly, distinctly narrowed posteriorly in dorsal view. Surface of disc glossy, distinctly punctate, punctures similar to those on head; setation as on head, ratther evenly spaced and short.

Elytra 1.7 times as long as wide, subparallel, rounded apically; humeri well-developed; apices modified, channel of gland forming short tubular process at apical margin. Surface moderately glossy, densely punctate; punctures more delicate than those on head, distinctly spaced; setation as on head, short, subdecumbent.

Legs simple, only metatibia slightly narrowed in terminal part (impressed subapically on outer side); all tibiae with paired terminal spurs.

Abdominal sternum VII shallowly emarginate apically; sternum VIII forming paired subtriangular sclerites. Aedeagus ( Fig. 108 View Figs 105–111. 105 ): apical portion of tegmen slender, conspicuously hooked, with slight subapical tooth; endophallic armature with pair of longer straight spinules, numerous small, tooth-like spinules, and spinulose scales (similar to those in Fig. 102 View Figs 100–104. 100 ).

Female. Identical with male for most external characters; elytral apices simple; sternum VII simple; tergum VII subtriangular, with shallow apical excavation.

Variation. Body length (♀) 2.5–3.0 mm.

Differential diagnosis. Microhoria impavida sp. nov. belongs to the M. terminata species-group. Externally it slightly resembles M. halophila sp. nov., but differs by the more slender body, prominent elytral humeri, the excavate apex of female tergum VII, and by characters of aedeagus, which is substantially different both in shape of the tegmen and structure of the endophallus (cf. Figs 108 View Figs 105–111. 105 versus 103).

Etymology. From the Latin impavidus (intrepid); named in reference to the shape of the tegmen, which is armed with robust hook; adjective.

Distribution. Turkey.

Knížek lgt.( ZKDC); 8 7 ♀♀, same data, except:P. Zahradník lgt. ( ZKDC); 1, Namrun, 1200 m, 30.v.–10.vi.1968, C. Holzschuh lgt. ( ZKDC); 1, same locality, 7.–13.vii.1992, D. Hauck lgt. ( ZKDC).

Diagnosis. Microhoria terminata species-group; minute, apterous, at least partly reddish species. Male sternum VII moderately emarginate apically; sternum VIII forming paired subtriangular sclerites that are rounded apically, narrowly touching/connected medially; tergum VII and VIII simple.Aedeagus ( Figs 109, 110 View Figs 105–111. 105 ): apical portion of tegmen moderately widened and curved, endophallic armature with pair of long and strongly curved, comparatively robust spines. Female sternum VII simple; tergum VII simple.

Variation. Body length (♀) 1.9–2.5 mm. Body mostly with reddish pronotum and darker, brownish to brownish- -black head and elytra; sometimes largely reddish coloured.

Distribution. Turkey.

Remarks. PIC (1904, 1908) described both Anthicus tauricus and A. tauricus v. nov. inobscura from the Taurus Mountains in Turkey; the former species was described from a single specimen, the latter from an unstated number of specimens (‘plusieurs examplaires’). The latter taxon was treated as an aberration by WINKLER (1927), and thus placed as synonym of Microhoria taurica in the last Palaearctic catalogue ( CHANDLER et al. 2008). However, they are here treated as separate species. Based on photographs provided by D. Telnov, the holotype of M. taurica differs as follows: male sternite VII rather deeply emarginate apically, with lateral sides of emargination moderately lobed, apical portion of tegmen straight, slender; paired endophallic spines minute, shaped similarly to those in Fig. 104 View Figs 100–104. 100 .

The syntypes of M. inobscura bear the locality data ‘Hadjin Dagh’, but there is no Mount Hadjin in the Taurus Mountains. The word ‘Hadjin’ refers most probably to the mountains around Saimbeyli village (formerly Hadjin) in Adana Province (A. Ӧ. Koçak, pers. comm.).
