摘要

Japanese species of the genus Zatypota are revised and a total of twelve species are recognized. Nine of them, Z. baragi sp. nov., Z. brachycera sp. nov., Z. chryssophaga sp. nov., Z. dendrobia sp. nov., Z. elegans sp. nov., Z. maculata sp. nov., Z sulcata sp. nov., Z. takayu sp. nov. and Z. yambar sp. nov., are new to science and one, Z percontatoria, is newly recorded from Japan. Host records are given for ten species including seven new and one newly recorded species based on reared materials. Each species utilizes different spider species as hosts. All host spiders belong to Theridiidae (nine species) and Linyphiidae (Z. sulcata). A key to Japanese species is provided and notes on their biology are given.
