ABSTRACT: The erigonine spider genus Sisicottus is revised for the first time. Cladistic Sisicottus suggests the following hypothesis of interspecific relationships: ((S. montigenus, panopeus (S. montanus (S. crossoclavis (S. cynthiae (S. orites (S. nesides, S. aenigmaticus))))))). monophyly of the genus is unambiguously supported by six putative synapomorphies: hook, a suprategular membrane projecting apically from the distal suprategular apophysis, that originate on the ectal side of the spermathecae, imbricated stridulatory striae, the dorsal macrosetae on tibia III, and the absence of a trichobothrium on metatarsus IV. Evidence monophyly of each Sisicottus species is discussed. A taxonomic key, diagnoses, descriptions, character values, illustrations, locality records, natural history information, and distribution sented for the nine recognized species. Five new species are described: S. quoylei, crossoclavis, 5. cynthiae, and S. aenigmaticus. Typhochrestus uintanus (NEW COMBINATION) mally transferred out of Sisicottus
