Abstract

A new genus, Martensiellus, is established for Martensiellus tenuipalpus n. sp. from central Sarawak. The distad-directed, expandable glans penis of this species indicates a close relationship with Biantoncopus fuscus Martens & Schwendinger from the Philippines. Females of two other species from eastern Sarawak and southern Kalimantan, which presumably also belong to Martensiellus n. g., are presented but not formally described. A dorsal pore, similar to the pore organ of Ricinulei, is reported to be present on undivided leg tarsi of mature specimens of Martensiellus tenuipalpus n. sp., ?Martensiellus n. g. spp., Palaeoncopus spp., Caenoncopus spp. and Oncopus spp. This character is considered as apomorphic for Oncopodidae, providing further support for monophyly of this family.
