Introduction
Alopecosa Simon, 1885 is a large genus of wolf spiders containing more than 160 named species worldwide [Platnick, 2013], of which many species remain known from the original descriptions only. The aim of the present work is to redescribe the male holotype of Tarentula krynickii Thorell, 1875, one of the least known south European species of wolf spiders, and to justify a transfer of this species to genus Alopecosa. The male holotype is deposited in the Finnish Museum of Natural History, University of Heslinki, Finland (FMNH; curator: Dr P. Cardoso). The terminology and format of description follow Logunov [2010]. Abbreviations used in the text: AME anterior median eye, ALE anterior lateral eye, Fm femur, MA median apophysis, Mt metatarsus, PME posterior median eye, PLE posterior lateral eye, Pt patella, Tb tibia, Tr tarsus. The sequence of leg segments in measurement data is as follows: Fm + Pt + Tb + Mt + Tr (total). All measurements are in mm.

DIAGNOSIS. Alopecosa krynickii seems to belong to the striatipes species group [sensu Lugetti & Tongiorgi, 1969] and is similar to A. taeniopus (Kulczyсski, 1895) and A. beckeri (Thorell, 1875); see Nadolny & Kovblyuk [2010] for detailed descriptions and a comparison of both species. A. krynickii differs from both these species, as well as from all other Alopecosa species known to me, by the unique shape of the median apophysis that has a wide, spoon-shaped lateral extension bent ventrad (Figs 45). A more detailed diagnosis of this species will be possible, when more male specimens and also females are collected. To date, the species remains known from the male holotype only. DESCRIPTION. MALE (holotype). Carapace 7.35 long, 5.05 wide. Eye sizes and interdistances (Fig. 7): AME 0.35, ALE 0.26, PME 0.78, PLE 0.63, AME AME 0.20, AMEALE 0.10, PMEPME 0.53, PLE PLE 1.45. Width of anterior eye row 1.55, second row 1.93, third row 2.15. Clypeus height 0.19, chelicera length 3.20. Abdomen 7.00 long, 4.00 wide. Length of leg segments: I 5.90 + 2.50 + 4.40 + 4.80 + 2.90 (20.50); II 5.45 + 2.40 + 4.10 + 4.65 + 2.90 (19.50); III 4.90 + 2.35 + 3.50 + 4.60 + 2.60 (17.95); IV 6.40 + 2.70 + 4.75 + 6.40 + 3.20 (23.45). Leg formula: IV, I, II, III. Coloration (Figs 12), the specimen is visibly faded. Carapace yellowish orange, covered with white and brown hairs. Sternum yellow, densely covered with brown hairs. Maxillae and labium orange, with white apices. Chelicerae light, yellowish brown. Abdomen: dorsum and sides yellowish orange, with no pattern and with poorly marked cardiac mark (Fig. 1, but the specimen is faded!); venter dark brown and densely

D.V. Logunov the fact that this species was assigned by Roewer [1955] to the genus Avicosa Chamberlin et Ivie, 1942 which was later synonymized with Schizocosa [Dondale & Redner, 1978: 146]. However, A. krynickii possesses none of the two main diagnostic characters of Schizocosa males (see Dondale & Redner [1978: 147, figs 1 26; 1990: 54]): viz., the embolus with broad par pendula and distally bent intromittent part and the scalelike terminal apophysis. Besides, according to Dondale & Redner [1990], the genus Schizocosa containing 21 valid species is restricted to North America. Thus, the assignment of A. krynickii to the genus Schizocosa seems to have been unjustified. In his original description, Thorell [1875b: 158] compared A. krynickii with Trochosa dimidiata Thorell 1875, the type species of the poorly diagnosed genus Mustelicosa Roewer, 1960 [Marusik & Buchar, 2004: figs 18; Platnick, 2013]. Indeed, A. krynickii has got the same leg formula (IV, I, II, III) and two retromarginal teeth on the chelicerae (Fig. 6) [cf. Roewer, 1960: 917]. However, both characters seem to be shared by a number of Alopecosa-like genera of wolf spiders and thus seem to be of little taxonomic value. The main difference between the males of A. krynickii and M. dimidiata lies in the conformation of their palps, particularly in the presence of well-developed, embolus-like synemolus in M. dimidiata and its absence in A. krynickii. The embolus-like structure on the Fig. 1 in Marusik & Buchar [2004: 154] and Fig. 22.10 in Marusik & Kovblyuk [2011: 185] is actually the synembolus [sensu Logunov, 2010]. The real, rather thin embolus of M. dimidiata is hidden behind the median apophysis and lies below the synembolus (not shown by Marusik & Buchar [2004]). The taxonomic status of Mustelicosa or an analysis of the detailed conformation of copulatory organs of its species are outside the scope of this paper. It is worth mentioning though that the presence of synembolus is a reliable diagnostic character to separate Mustelicosa from Alopecosa that warrants its independent taxonomic status, however the scope of the former genus needs further thorough study. For the present discussion it is enough to just stress that, in my opinion, A. krynickii cannot be assigned to Mustelicosa. To conclude the discussion, A. krynickii shares all the man diagnostic characters of true Alopecosa [sensu Dondale & Redner, 1990]: viz, medium body size; the presence of a cardiac mark on the abdomen (Fig. 1), which is visibly faded in the holotype; cheliceral retromargin with two teeth (Fig. 6); femur I with a prolateral spine; the angular median apophysis (Figs 45); the palea with a poorly marked pointed prominence (Fig. 4). Therefore, a transfer of Tarentula krynickii to the genus Alopecosa, as already proposed above, seems to be well justified. Finally, the genus Schizocosa should be removed from the list of European Lycosidae [cf. Helsingen, 2013; Nentwig et al., 2013].

covered with brown hairs in its anterior half, and yellowish orange in its posterior half (Fig. 2). Book-lung covers yellow, densely covered with brown hairs. Spinnerets yellow. All legs yellowish orange, covered with white hairs; tibiae and metatarsi I darker brownish. Palpal structure as in Figs 45: the embolus seems to be narrow, it is almost invisible behind the median apophysis; the median apophysis is wide and elongated laterad, with the spoon-shaped lateral extension having a tooth directed ventrad; the palea with a poorly marked pointed prominence; the functional conductor is small and poorly visible. FEMALE unknown. DISTRIBUTION. Ukraine, the Crimea: the type locality only.

Taxonomic notes
In Platnick [2013] and in a number of regional catalogues [e.g., Kovblyuk, 2003; Mikhailov, 2013; etc.] Alopecosa krynickii is listed under the genus Schizocosa Chamberlin, 1904, apparently resulting from
