Abstract: Since 1885 and for almost a century the Kamchatka Peninsula had been a region of Russia east of the Urals with the best studied spider fauna. Currently, Kamchatka can be considered the least studied Siberian region. In this paper, we have provided a brief overview of Tatyana V. Pavlenko's spider collection compiled in Kamchatka in 1988-1992. A species list contains 108 species belonging to 15 families, of which 25 species, five genera and the family Titanoecidae are new to the spider fauna of Kamchatka. Walckenaeria subspiralis Millidge, 1983 is recorded from the Palaearctic Region for the first time. Kolymocyba petrophila Eskov, 1989 previously known from Magadan Area only is illustrated to provide more detail data about its morphology. The female of Micaria yeniseica Marusik & Koponen, 2002 that was previously known from the holotype male from the middle reaches of Yenisei River only is described for the first time. Two species – M. yeniseica and Zelotes azsheganovae Esyunin & Efimik, 1992 – significantly extended their known range to the east. Based on new data, a total number of the spider species known from Kamchatka has extended to 273.

A new genus of Liocranidae (Arachnida: Araneae) from Tajikistan https://abs.pensoft.net/article/59687/ Acta Biologica Sibirica 6: 583-594

DOI: 10.3897/abs.6.e59687

Authors: Yuri M. Marusik, Alexander A. Fomichev

Abstract: A new genus, Platnick gen. n., with three new species, P. shablyai sp. n. (♂, type species), P. astana sp. n. (♀) and P. sanglok sp. n. (♀), are described from Tajikistan. The male of the type species has a unique pair of longitudinal ventral postgastral scuta. Females have such scuta also, but they are much shorter. The new genus is placed in Liocranidae Simon, 1897. A discussion on the subfamilies of Liocranidae and comments on the family-group names are provided.

New data on spiders (Arachnida, Aranei) from the caves of Southwestern Siberia (Russia) https://abs.pensoft.net/article/59450/ Acta Biologica Sibirica 6: 429-436

DOI: 10.3897/abs.6.e59450

Authors: Alexander A. Fomichev

Abstract: The paper reports six species of spiders from five families found in three caves located in the Altai Krai, Novosibirsk Oblast and Kemerovo Oblast of Russia. One troglophilic species, Improphantes improbulus (Simon, 1929) is recorded from Siberia and the Altai Mountains for the first time and another troglophile species, Metellina merianae (Scopoli, 1763) is recorded from the Novosibirsk Oblast for the first time. Improphantes improbulus, a species new to Siberia, is illustrated. The distribution and habitat preferences of all six species is discussed.
