The infective juveniles of<jats:italic>S. pwaniensis<\/jats:italic>n. sp. are characterized by a body length of 978\u00a0\u03bcm (808\u20131131), distance from anterior end to excretory pore of 86\u00a0\u03bcm (80\u201395) and a tail length of 87\u00a0\u03bcm (75\u201395). The ratios<jats:italic>a<\/jats:italic>,<jats:italic>c<\/jats:italic>and<jats:italic>E<\/jats:italic>% of<jats:italic>S. pwaniensis<\/jats:italic>n. sp. are substantially lower than those of all other African \u2018<jats:italic>glaseri\u2019<\/jats:italic>group members. The first-generation males of<jats:italic>S. pwaniensis<\/jats:italic>n. sp. can be distinguished by a large spicule length of 92\u00a0\u03bcm (80\u201397) and by the absence of the caudal mucron, while second-generation males possess a short spine-like mucron. First-generation females have a peg-like tail tip bearing three spine-like projections. Second-generation females can be recognized by a slightly protruding vulva and well-developed post-anal swelling. The new species is further characterized by sequences of the internal transcribed spacer (ITS) and partial 28S regions of the ribosomal DNA. Phylogenetic analyses show that<jats:italic>S. pwaniensis<\/jats:italic>n. sp. forms a strongly supported monophyletic clade with two other East African species,<jats:italic>S.
