The phylogeny of the spider family Sparassidae is comprehensively investigated using four molecular markers (mitochondrial COI and 16S; nuclear H3 and 28S). Sparassidae was recovered as monophyletic and as most basal group within the RTA-clade. The higher-level clade Dionycha was not but monophyly of RTA-clade was supported. No affiliation of Sparassidae to other members of the 鈥楲aterigradae鈥?(Philodromidae, Selenopidae and Thomisidae) was observed, and the crab-like posture of this group assumed a result of convergent evolution. Only Philodromidae and Selenopidae were found members of a supported clade, but together with Salticidae and Corinnidae, while Thomisidae was nested within the higher Lycosoidea. Within Sparassidae monophyly of the subfamilies Heteropodinae sensu stricto, Palystinae and Deleninae was recovered. Sparianthinae was supported as the most basal clade within Sparassidae. Sparassinae and the genus Olios were found each to be polyphyletic. Eusparassinae was not recovered monophyletic, with the two original genera Eusparassus and Pseudomicrommata in separate clades and only the latter clustered with most other assumed Eusparassinae, here termed the 鈥淎frican clade鈥? Further focus was on the monophyletic genus Eusparassus and its proposed species groups, of which the dufouri-, walckenaeri- and doriae-group were confirmed as monophyletic with the two latter groups more closely related. According to molecular clock analyses, the divergence time of Sparassidae and Eusparassus was estimated with 186 and 70 million years ago respectively.
