Capnioneura bolkari sp. n.

( Figs. 1-5 )

Material examined. Holotype ♂: Turkey, Central Taurus , North West Tarsus , brook and spring between Camliyalya and Bögrüegri, 34°36'E / 37°09'N, 4-V-97. The holotype and one female paratype are deposited in the Zoological Museum of Lausanne , Switzerland. Other paratypes, same locality, 5♂, 13♀; brook below Dorak, South Camliyalya, 34°42'E / 37°02'N, 4-V-97, 3♂, 2♀ (held in Sivec and Vinçon collections).

Description. Body length ♂ 5.5 – 6.1 mm, ♀ 5.8 –

6.5 mm. ♂ slightly brachypterous: anterior wing 3.8 – 4.1 mm. ♀ normally winged: anterior wing 5.7 – 6.0 mm. Head and whole body dark brown.

Male ( Fig. 1-3 ). Tergite VII-VIII with a wide rounded membraneous field on the posterior margin. Tergite IX similar, forming a transversal sclerotized strip that narrows medially; the anterior margin is strongly curved. Tergite X with rounded anterior margin and sub-triangular median membraneous field ( Fig. 1 ). Epiproct regularly curved at its base and ending into a rounded apex with a triangular anterior tooth; another tooth is also present one third of the distance from the tip of the epiproct, on the anterior edge ( Fig. 2 ). Specillum hook-shaped, ending in a sharp point ( Fig. 3 ). Paraproct shaft more or less rectilinear, blade-shaped, and regularly narrowing toward the apex ( Fig. 2 ). Cercus rather thick, becoming thinner towards the apex ( Fig. 1 ).

Female ( Fig. 4-5 ). Tergite I-VIII with wide median membraneous area. Tergite IX-X fully sclerotized. Sternite VII: the wide subgenital plate has a sub triangular posterior extension that covers the median part of sternite VIII and nearly reaches the middle of sternite VIII. Sternite VIII with a median membraneous area, partly crossed by the projection of sternite VII; on each side of this membraneous field, two anterior and two posterior dark spots are clearly visible on the inner edge of the lateral plates.

Affinities. Male related to Capnioneura petitpierrae Aubert by the shape of the specillum and paraproct blades, but the epiproct is quite different and resembles that of C. mitis Despax and C. caucasica Zhiltzova. It differs from C. caucasica and C. mitis by the shape of the specillum, ending in an acute hook, and by the slightly curved apex of the paraproct blades. The female is close to those of C. caucasica and C. petitpierrae , from which it differs mainly by the two posterior spots on sternite VII.

Etymology. Named after the mountainous region where the species occurs. The Bolkar Daglari is a high altitude mountain range that culminates at 3524 m a.s.l. (Medetsiz Tape), in the Central Taurus.

Ecology. Orophilic, crenophilic species occurring in mountain springs and brooklets on a calcareous substratum. The altitude of the localities, though not measured with precision, is higher than 1000 m a.s.l.

Distribution. This micro-endemic species is only known from two localities in the same mountainous region, northwards Tarsus (Central Taurus) ( Fig. 12 ).
