Specimens of spiders (Arachnida, Araneae) collected on Mikurajima Island, Izu Is- lands, Tokyo, Japan, are taxonomically studied and 49 species of 22 families are recorded from the island. A list of 86 spiders species of the island is compiled with obtained data and known records from literatures. Three new species discovered in the present material are described under the names, Paikiniana mikurana sp. nov. (Linyphiidae), Tmeticodes gibbifer gen. et sp. nov. (Linyphi- idae) and Nesopholcomma izuense gen. et sp. nov. (Theridiidae). Two new genera, Tmeticodes gen. nov. (type species: Tmeticodes gibbifer sp. nov.) and Nesopholcomma gen. nov. (type species: Ne- sopholcomma izuense sp. nov.), are established and diagnosed.
