Alopecosa albostriata (Grube, 1861) Figs 1–22, 35 Lycosa (Tarantula) albostriata Grube, 1861: 174 (juv.). Lycosa albostriata: Schmidt 1895: 462 (♀). Tarentula albostriata: Kulczyński 1908: 71, pl. 3, f. 84, 89, 94 (♂ ♀). Alopecosa albostriata: Roewer 1955: 213 (transfer to Alopecosa). Alopecosa albostriata: Wesołowska 1988: 406, f. 9‒11 (♀). Note 1. All other references (in total 32) listed under A. albostriata in Platnick (2014) and World Spider Catalog (2018) refer to other species, related to Mustelicosa dimidiata (Thorell, 1875). Note 2. Although the type was not studied, the species was recognized based on the figures provided by Kulczyński (1908) and material from Yakutia listed below and studied earlier (Marusik et al. 1993). Material examined: RUSSIA: 1♂ (ISEA), Krasnoyarsk Prov., Turukhansk Dist., Tsentralno-sibirski Reserve, Yenisei R., Komsa kordon, 61.84°N, 89.45°E, 25–30 m, 19 – 26.06. 2016 (V.K. Zinchenko); 17♂ 1♀ (ZMMU), Yakutia, Yana River, middle flow of Tuostakh River (right tributary of Adycha River), ca. 67°17’N, 137°07’E, Summer 1989 (V.V. Sivtsev); 15♂ 2♀ (IBPN), Magadan Area, Kulu River upper flow, Kontakt Field Station, 61°51’N, 147°40’E, 500 m, Summer 1999 (S.P. Bukhkalo). Comparative material: Alopecosa mutabilis: RUSSIA: 1♂ 15♀ (ZMMU), Arkhangelsk Area, Barents Sea, Dolgiy Island, Nenets Reserve, 69°12’N, 59°13’E, 6– 28.07.2004 (O.L. Makarova); 32♂ 15♀ (IBPN), Chukotka, Wrangel Island, SE part, Mamontovaya River middle flow, 71°10’N, 179°46’W, June–July 2006 (O.A. Khrulyova). Diagnosis. Males of A. albostriata can be easily distinguished from congeners occurring in Siberia by the light tibia-tarsi, which lacks any pattern (other species have dark tibia-metatarsi or transversal bands) and longitudinal whitish stripe on abdomen (found in majority of specimens). The male palp of A. albostriata is most similar to those of A. mutabilis, but differs by having broad tegular apophysis with a flat and bent tip and a triangle outgrowth (Figs 16, 24), all absent in other Alopecosa species.
