Centipedes of the genus Scolopocryptops Newport, 1844 are blind species mostly described from the New World and East Asia. In this study, a Japanese species, S. quadristriatus (Verhoeff, 1934), which is characterised by four longitudinal keels on the tergites, is re-described, based on the likely holotype preserved in the Zoologische Staatssammlung München and specimens newly collected from near the type locality. In addition, S. longisetosus sp. nov., a new species that bears tergal keels like S. quadristriatus, is described from the Ryukyu Islands in Japan and Taiwan. Although the presence of four keels on tergites is unique to these two species, phylogenetic analyses using nuclear and mitochondrial markers showed that S. longisetosus sp. nov. is not sister to S. quadristriatus. The obtained phylogeny indicates that the tergal longitudinal keels evolved in parallel within Scolopocryptops or that the presence of keels represents a plesiomorphic character of the clade containing these species.
