The Pardosa nebulosa-group consists of at least 66 species, including 14 species recorded from the South China. In this paper, we describe two new species of this group, P. tuberosa sp. nov. and P. parathompsoni sp. nov. from Yunnan Province of China. Also, P. shuangjiangensis Yin et al., 1997 is newly synonymised with P. pusiola (Thorell, 1891), based on the examination of specimens mainly fro...

Two species previously known from East Kazakhstan, Acantholycosa katunensis Marusik, Azarkina & Koponen, 2004, known from the holotype male, and Acantholycosa kurchumensis Marusik, Azarkina & Koponen, 2004, syn. n. known from females, are synonymized, and priority is given to Acantholycosa katunensis. Acantholycosa katunensis is reported for the first time in the Russian Altai. Both sexes of th...

Three species of Xerolycosa: Xerolycosa nemoralis (Westring, 1861), Xerolycosa miniata (C.L. Koch, 1834) and Xerolycosa mongolica (Schenkel, 1963), occurring in the Palaearctic Region are surveyed, illustrated and redescribed. Arctosa mongolica Schenkel, 1963 is removed from synonymy with Xerolycosa nemoralis and transferred to Xerolycosa, and the new combination Xerolycosa mongolica (Schenkel,...

Alopecosa ogorodica sp.n. (♂♀), a new wolf-spider species (Lycosidae) from the Russian Mountain Altai is described. New data, diagnosis, description and drawings on Arctosa meitanensis Yin et al., 1993 are provided. 

Schizocosa malitiosa and Aglaoctenus lagotis are two wolf spiders (Lycosidae) that inhabit grasslands hills of Uruguay. While S. presents a wandering life habit, A. is sedentary, lives in web. In the present study, we experimentally evaluated capture behavior both species on "known" substrate another "unknown" one. To do this, placed (wandering) sand later At same time exposed to (sedentary), w...

Vesubia jugorum (Simon, 1881) (Araneae: Lycosidae) is a large-sized wolf spider that occurs in alpine rocky areas above 2,000 m altitude. The species is stenoendemic, with a limited number of populations documented in the literature from the Maritime Alps (Italy, France). Due to the climate change, the current observed extent of occurrence (EEO 4,412 km ) and the area of occupancy (AOO 835 km )...

A species of the family Lycosidae, Venonia spirocysta Chai 1991, is reported from Japan for first time. The specimens were collected Tarama-jima Island, Okinawa Prefecture. genus also newly recorded Japan, but since generic placement V. problematic, this may be transferred to another in future.

The monotypic genus Nukuhiva Berland, 1935 with N. adamsoni (Berland, 1933) as type species, is re-described and transferred from the Pisauridae Simon, 1890 (fishing or nursery-web spiders) to the Lycosidae Sundevall, 1833 (wolf spiders) based on genitalic and somatic characters. Nukuhiva adamsoni, originally described from French Polynesia, appears to inhabit mountainous habitats of volcanic o...
