Info
A small, but world-wide genus, Coriarachne is found in boreal and temperate regions. The greatest number of species are found in North America where there are four. Coriarachne depressa (C. L. Koch) is the only species recorded from Europe . Little is known of the Oriental fauna except for C fulvipes (Karsch), which was recorded from Japan by Yaginuma (1970), and Cnigrostriata Simon is cited by Bonnet (1956), from Indochina. Spiders of the genus Coriarachne are rather slow-moving and robust with the typica l crab-like appearance characteristic of the subfamily Thomisinae . As with the rest of the subfamily, species of Coriarachne wait to ambush their prey rather than actively pursuing it. They are found almost exclusively on tree bark, wooden fence posts and the like where their color camouflages them. Often these spiders will congregate under loose bark, leaf litter, or similar situations to spend the winter either in the adult or penultimate stage (Jennings, 1972 ; Holmquist, 1926 ; Kaston, 1948 ; Lowrie, 1948).
