Three new genera and one subgenus are established: Loeblicasubgen. n. (type species: Tisaniba loebli sp. n.), Paraeuophrysgen. n. (type species: P. sumatranasp. n.), Thaiattusgen. n. (type species: T. krabisp. n.), Tisanibaineptagen. n. (type species: Tisaniba bijibijanZhang & Maddison, 2014). The subgenus Chalcovietnamicus Marusik, 1991, stat. n. is raised to a status of full genus. The genus ParvattusZhang & Maddison, 2012, syn. n. is synonymized with Chalcovietnamicus Marusik, 1991. Seventeen new species are described: Chalcovietnamicus nagasp. n. (♂, Philippines), Euochin luzonicasp. n. (♀, Philippines), Microemathis bulalacaosp. n. (♂♀, Philippines), Paraeuophrys sumatranasp. n. (♂♀, Indonesia), Thaiattus krabisp. n. (♂♀, Thailand), Tisaniba (Loeblica) inusitatasp. n. (♂♀, West Malaysia), Tisaniba (Loeblica) loeblisp. n. (♂♀, West Malaysia), Tisaniba (Loeblica) rimbosp. n. (♂♀, Indonesia), Tisaniba (Loeblica) tiomansp. n. (♂, West Malaysia), Tisaniba (s. str.) berausp. n. (♂♀, Indonesia), Tisaniba (s. str.) ligoformasp. n. (♂♀, Indonesia), Tisaniba (s. str.) mayangsp. n. (♂, Indonesia), Tisaniba (s. str.) nitidasp. n. (♂♀, Indonesia), Tisaniba (s. str.) schwendingerisp. n. (♂♀, Indonesia), Tisanibainepta pahangsp. n. (♂♀, West Malaysia), Tisanibainepta palawansp. n. (♂♀, Philippines), Tisanibainepta silvaticasp. n. (♀, Philippines). Thirteen new combinations are proposed: Chalcoscirtus jirica (Żabka, 1980), comb. n. (ex Euophrys), Chalcoscirtus nangqianensis (Hu, 2001), comb. n. (ex Euophrys), Chalcovietnamicus tengchongensis (Lei & Peng, 2012), comb. n. (ex Euophrys); Chalcovietnamicus vietnamensis (Żabka, 1985), comb. n. (ex Chalcoscirtus); Chalcovietnamicus zhui (Zhang & Maddison, 2012), comb. n. (ex Parvattus), Euochin kororensis (Berry, Beatty & Prószyński, 1996), comb. n. (ex Euophrys), Euochin subwanyan (Wang & Li, 2020), comb. n. (ex Euophrys), Euochin wanyan (Berry, Beatty & Prószyński, 1996), comb. n. (ex Euophrys), Paraeuophrys bryophila (Berry, Beatty & Prószyński, 1996), comb. n. (ex Euophrys); Phintella albopatella (Petrunkevitch, 1914), comb. n. (ex Euophrys), Tisanibainepta bijibijan (Zhang & Maddison, 2014), comb. n. (ex Tisaniba), Tisanibainepta kubah (Zhang & Maddison, 2014), comb. n. (ex Tisaniba), Tisanibainepta selasi (Zhang & Maddison, 2014), comb. n. (ex Tisaniba). Three Euophrys species names are recognized as nomina dubia: E. auricolorDyal, 1935 (♂, Pakistan), E. rubroclypeaDyal, 1935 (♀, Pakistan), E. rufaDyal, 1935 (juv., Pakistan). A brief discussion on Euophrys C. L. Koch, 1834 in South-East Asia and the nomenclature of its Oriental species is provided. Distribution of all newly described species is mapped.
