Ichthyocephaloides sumbatus n. sp., from the gut of Salpidobolus sp. (Spirobolida: Rhinocricidae), collected in the forest covering the mountainous region of Sumba Island, Indonesia, is described and illustrated. The new species is morphologically related to Australasian species of Ichthyocephaloides by the presence of a long, subulate tail in both sexes, distribution and number of genital papillae, presence of genital diverticulum and anterior position of vulva. Ichthyocephaloides sumbatus n. sp. is distinguished from all other nominal species by the highest mean right/left spicule length ratio and the exceptional form of the anterior vulval lip. The original description of Xystrognathus phrissus is supplemented with a description of the juvenile morphology and illustrated with line graphics and SEM images of adult stages. Molecular sequences and phylogenetic trees are provided.
