Hahnia ononidum Simon, 1875 ( Figures 3 , 6 , and 7)

Hahnia ononidum : Harm, 1966: 362, f. 46‒50 (♂ ♀); Opell and Beatty, 1976: 426, f. 89–93 (♂ ♀); Roberts, 1998: 272, f. (♂ ♀); Almquist, 2005: 277, f. 261a‒e (♂ ♀).

Material examined. UKRAINE. Crimea: Feodosiya Distr.: 1 ♂ ( TNU), Karadag Nature Reserve, Beregovoy Mt. Range near Biological Station , 16– 30.11.2006, O. V . Kukushkin; Simferopol Distr.: 4 ♀♀ ( TNU), Chatyr-Dagh Mt. , Orlinoe canyon, 44°49.014′N, 34°18.762′E, 637 m, 17.03.2002, M. K.; 3 ♂♂, 26 ♀♀ ( IBPN), same locality and date, Yu. M .

Diagnosis. Male of H. ononidum is similar to that of H. nava , but it differs from the latter with the presence of the tegular brush (“comb”) on the base of the tegulum (lacking in H. nava ), the longer patellar apophysis, and shorter tibial setae (longer in H. nava ) ( Figure 6 ).

The shape of the copulatory ducts distinguishes female of H. ononidum from all other Hahnia species ( Figure 7 ). In addition, females of H. ononidum differ from other Crimean Hahnia species by presence of peculiar epigastric sulci (sclerotized part) near the posterior of epigyne ( Marusik and Kunt, 2009; Marusik et al., 2011).

Description. Somatic characters well described in above-mentioned publications. Male palp as in Figure 6 . Patellar apophysis long, distally hook-like bent. RTA strongly bent, sickle-shaped, and its tip approximately reaches the middle of tibia but not dorsum of tibia. Tibial setae short and do not reach the RTA. Conductor directed retrolaterally. Tegulum with brush (“comb”) in the basal part. Embolus originating retrolaterally and coiling clockwise 315° along the margin of the tegulum (left palp).

KOVBLYUK et al. / Turk J Zool

Epigyne as in Figure 7 . Copulatory openings located in the posterior third of the epigynal plate. Secondary receptacles slightly smaller than primary receptacles. Epigyne with two dark small dots.

Distribution. Circum-Holarctic polyzonal range ( Marusik and Kunt, 2009; Marusik et al., 2011).

Comments. Hahnia ononidum is recorded from Crimea for the first time.

Habitats. Stony mountain steppes and forests.

Phenology. In Crimea males were collected in March and November, and females in March. In Sweden: ♂♂ – IV ‒ IX , ♀♀ – IV ‒X , ♂ ♀ – IV ‒ IX ( Almquist, 2005). Males and females in Crimea were collected 1 month earlier than in Sweden . Thus, the period of activity of adults H. ononidum in Crimea is 2 months longer than in Sweden.
