First record of a schizomid, Stenochrus portoricensis (Schizomida: Hubbardiidae), in Slovakia

The order Schizomida is a small group of arachnids, currently represented by two recent families: Protoschizomidae Rowland, 1975 with two genera and 12 species; and Hubbardiidae Cook, 1899 with 48 genera and 271 species worldwide (Harvey 2007, Armas 2010, Monjaraz-Ruedas 2012). Schizomids can be found in leaf litter, under rocks, in caves and other subterranean voids, in many tropical and subtropical regions of the world. Some species have been recorded from greenhouses and other artificial environments in Europe, demonstrating their ability to withstand long-distance transport by human commerce (Harvey 2003). Three species have previously been recorded from greenhouses in Europe. Schizomus crassicaudatus (O. P.-Cambridge, 1872) was introduced from Sri-Lanka into France. Zomus bagnallii ( Jackson, 1908) was introduced from Southeast Asia, the Seychelles or Mauritius into Great Britain (Harvey 2003, Blick 2006). Stenochrus portoricensis Chamberlin, 1922 has been introduced into Great Britain, Spain (Canary Islands) and the Czech Republic (Harvey 2003, Blick 2006, Korenko et al. 2009). All of the specimens from Europe were collected from heated greenhouses. Undetermined schizomids have been collected from two greenhouses in Germany (Cokendolpher et al. 2006).
