ABSTRACT. The linyphiid spiders from Thailand and West Malaysia kept at the Muséum d’histoire naturelle de Genève are studied. Three new genera and nine new species are described: Aperturina gen.n. (the type species: A. paniculus sp.n.), Apophygone gen.n. (the type species: A. simpulum sp.n.), Lamellasia gen.n. (the type species: L. mirabilis sp.n.), Asiagone siama sp.n., Batueta baculum sp.n., Nasoonaria magna sp.n., Oedothorax converter sp.n., Theoa elegans sp.n., and T. longicrusa sp.n. Twelve linyphiid species are recorded as new to the fauna of Thailand: Atypena cirrifrons (Heimer, 1984), Batueta voluta Locket, 1982, Erigone prominens Bцsenberg et Strand, 1906, Hylyphantes graminicola (Sundevall, 1830), “Linyphiachiridota (Thorell, 1895), Microbathyphantes palmarius (Marples, 1955), Nasoona crucifera (Thorell, 1895), Nasoonaria sinensis Wunderlich et Song, 1995, Neriene oxycera Tu et Li, 2006, Parameioneta spicata Locket, 1982, Tapinopa vara Locket, 1982 and Theoa tricaudata (Locket, 1982). Three linyphiid species, Gongylidioides pectinatus Tanasevitch, 2011, Nasoona crucifera and Plectembolus quinqueflectus Millidge et Russell-Smith, 1992, are newly recorded from West Malaysia. Based on the new data, the spider faunas of Thailand and West Malaysia are known to contain 43 and 24 linyphiid species, respectively.
