Hahnia pusilla C.L. Koch, 1841 ( Figure 8 )

Hahnia pusilla : Harm, 1966: 358, f. 36‒40 (♂ ♀); Roberts, 1998: 272, f. (♂ ♀); Almquist, 2005: 278, f. 262a‒f (♂ ♀).

Note. Hahnia pusilla is the type species of the genus.

Material examined. UKRAINE. Crimea: Simferopol Distr. : 1 ♀ (TNU-1754/12), environs of Skvortsovo Vill., steppe, pitfalls, 13‒ 27.04.2002, M. K .

Diagnosis. Male of H. pusilla is similar to H. helveola , but it differs by the shape of conductor (not pointed) and more rounded shape of tegulum. The shape of copulatory ducts distinguishes females of H. pusilla from all other Hahnia species ( Figure 8 ).

Description. Somatic characters are well described in above-mentioned papers. Epigyne as in Figure 8 . Copulatory openings located in the posterior third of the epigynal plate. Endogyne with 2 pairs of elongated receptacles subequal in size.

Distribution. West and Central Palearctic boreonemoral range: from Ireland and France to Baikal, and from Norway to Crete ( Helsdingen, 2013; Mikhailov, 2013; Nentwig et al., 2014).

KOVBLYUK et al. / Turk J Zool

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

Habitats. Steppe with Stipa and Festuca .

Phenology. In Crimea female was collected in April.

So far, four Hahnia species have been recorded from Crimea ( Kovblyuk, 2004a, 2004b, 2012; Kovblyuk et al., 2008a, 2008b; Mikhailov, 2013; Kovblyuk and Kastrygina, 2015; present data): H. helveola , H. nava , H. ononidum , and H. pusilla .

Traditionally, seven natural (landscape, altitudinal, geographical) zones are identified in the Crimean peninsula ( Kovblyuk, 2004a). The distribution of the Hahnia species in these zones is presented in the Table.

The richest zones in the number of recorded Hahnia species are the sub-Mediterranean forests of southern Crimea and the nemoral forests of the northern slope of the Crimean Mts. Two species were recorded in nemoral forests of the southern slope and only one species in genuine steppes, forest-steppes, and yailas. Hahnia was not found in the semidesert steppes and saline lands.
