Keys and brief descriptions of 17 species of the genera Robertus, Enoplognatha, Steatoda and Crustulina are given. A new species, Robertus yasudai, is described from the alpine snow-bed communities of Mts. Daisetsu, Hokkaido. A Chinese species, Enoplognatha lordosa Zhu & Song 1992, is recorded for the first time from Japan. Enoplognatha abrupta (Karsch 1879) and Clubiona parvula (S. Saito 1933) are newly transferred from Steatoda. Six species names are newly synonymized: Enoplognatha submargarita Yaginuma & Zhu 1992 with E. margarita Yaginuma 1964; E. japonica Bösenberg & Strand 1906, E. dorsinotata Bösenberg & Strand 1906 and Steatoda albimaculosa (S. Saito 1934) with E. tecta (Keyserling 1884); and E. transversifoveata (Bösenberg & Strand 1906) and E. hangzhouensis Zhu 1998 with E. abrupta (Karsch 1879). Two species names, S. japonica (Dönitz & Strand 1906) and S. minus (Dönitz & Strand 1906), are nomina dubia.
