Synonyms and other taxonomic changes
Note that many of the crab spiders in the genus Misumenops were transferred to the genus Mecaphesa in 2008 (see Lehtinen, P. T. & Y. M. Marusik. A redefinition of Misumenops F. O. Pickard-Cambridge, 1900 (Araneae, Thomisidae) and review of the New World species. Bull. Br. arachnol. Soc. 14: 173-198). This change is now reflected in our BG taxonomy.
130 species in 9 genera in our region, although some authors split them into 10 genera (1)
We have 14 genera following the world spider catalog.
See discussion on identification of three common flower-inhabiting genera (Misumena
, and Misumenops (Mecaphesa)
Spiders with very small (if strong) jaws (such as crab spiders and cobweb weavers) make small holes in the prey and vomit their digestive fluid into the prey's body, the end result being a hollow shell with some or most of the muscles and internal organs digested and sucked out. (2)
