Thai rhaphidophorid species of the genus Eurhaphidophora Gorochov 1999 are reviewed. Previously, two species and one subspecies (E. bispina Gorochov 2010; E. pawangkhananti Dawwrueng, Gorochov & Suwannapoom 2020; E. tarasovi doitungensis Dawwrueng, Gorochov & Suwannapoom 2020) were reported from Thailand. In this study, a new additional species (Eurhaphidophora apicoexcisa sp. nov.) from Ratchaburi Province is described. Males of this new large-sized species are easily recognized from other males of Eurhaphidophora by an almost straight and lamellar posteromedian process of the ninth abdominal tergite, the presence of a small but rather deep and rounded apical excision on this process, and a long apical part of the epiproct. Females of the new species also can be distinguished from other Thailand congeners by the presence of a small rounded posteromedian projection on the both eighth and ninth abdominal tergites, and a shortly triangular subgenital plate. An updated species catalogue of all known species and taxonomic keys to Thailand Eurhaphidophora species for males and females are provided.
