Thomisidae Checklist: Crab Spiders

on

Crab spiders from the family Thomisidae Sundevall,1833 are ambush predators and do not weave webs. The first two pairs of legs are typically longer and stronger, often armed with spines for grappling prey.

Checklist

This page consists of a personal checklist of all Crab Spiders (Thomisidae) that I’ve encountered over the years. Please do not assume the identification of a spider simply based on the photographs here as identification is usually based on examination of minute parts of the spider such as the genitalia.

All photos are of live subjects shot in the field, with the dorsal view selected where available. Click on individual photos for larger views and views from other angles. As most specimens were not collected, identifications were done purely based on photographs and may not be 100% accurate.

This page will be updated regularly, please let me know if you spot any mistakes.
