MATERIAL EXAMINED. 1 ♂, 1 ♀ (with marsupium), 1 juv. (ASU), Russia, southwestern Siberia, Altai Province, Barnaul, M.A. Lisavenko Research Institute for Horticulture of Siberia , heated hothouse, 16.06.2015, leg. P.S. Nefediev.

DISTRIBUTION. Throughout Europe and Asia Minor, in Great Britain including Northern Ireland, Ireland, the Netherlands, Belgium,

France, Germany, Switzerland, Austria, Hungary, Czech Republic, Slovakia, former YugoslaviaincludingBosniaandHerzegovina, Croatia, Serbia, Montenegro and Slovenia, Albania, mainland Italy together with Corsica, Greece including the Dodecanese Islands, Spain including the Balearic Islands, Romania, Bulgaria, Poland, Ukraine, Latvia, Lithuania, Estonia, Finland, Sweden, Norway, Denmark, Turkey, central and northeastern European Russia (the Kaluga, Moscow and Chelyabinsk areas), southern European Russia (the Rostov-on-Don and Voronezh areas and the Republic of Crimea); also introduced to northern Africa, as far as St. Helena Island in the Atlantic, the Americas ( Canada, USA, Mexico and Argentina), also Australia ( Vandel, 1962; Karaman, 1966; Leistikow, Wägele, 1999; Schmalfuss, 2003; Khisametdinova, 2011; Kuznetsova, Gongalsky, 2012; Boxshall, 2013).

REMARKS. At present, C. convexus has also been found introduced to a hothouse of the M.A. Lisavenko Research Institute for Horticulture of Siberia, Barnaul, Altai Province.Both the genus Cylisticus Schnitzler, 1853 , and the species C. convexus (De Geer, 1778) , as well as the family Cylisticidae they belong to, are recorded in the Asian part of Russia for the first time. According to the accepted classification of synanthrope woodlice ( Khisametdinova, 2009), C. convexus , being a fully synanthropic species, has partly lost its capability for existing beyond anthropogenic habitats. Such a distribution pattern is similar in Europe as well, where this species has only been found synanthropic in Finland ( Vilisics, Terhivuo, 2009), as well as in Ireland ( Cawley, 1996). Its distribution in North America shows the same pattern as described for

T. rathkii ( Hornung et al., 2015) . In addition, C. convexus females are capable for storing and repeatedlyutilizingsperm ( Suzuki,Ziegler,2005).
