对最近从老挝采集到的鳞翅目昆虫标本以及来自泰国和马来西亚西部的一些补充标本进行了研究。记述了6个新种和2个新属：Bathyphantes paracymbialsn.sp.，Nematogmus asiaticus n.sp.，Theoa Hamata n.sp.，Asiagone n.Gen.是为Asiagone signifera n.sp.而建的。(模式种)和穿孔毛壳菌A.pericata n.sp.为Laogone cephala n.sp.新异名如下：Gorbothorax Tanasevitch，1998 n.syn.=Nasoona Locket，1982；Paranasoona Hemer，1984 N.SYN.和Millploprys Platnick，1998 n.syn.=Atyena Simon，1894；Gorbothorax ungibbus Tanasevitch，1998 N.syn.=Oedothorax asocialis Wunderlich，1974；Hylyphantes Birmanicus(Thorell，1895)n.=H.graminicola(SunDevall，1830)。新组合如下：Atyena Cirrifrons(Hemer，1984)n.comb.A.pallida(Millidge，1995)和A.crocatoa(Millidge，1995)都是n.comb。Nosoona asociaris(Wunderlich，1974)n.comb.前Oedothorax Bertkau，1883；N.asocialis(Wunderlich，1974)，N.Comata(Tanasevitch，1998)，N.conica(Tanasevitch，1998)，N.setifera(Tanasevitch，1998)和N.wunderlichi(Brignoli，1983)，均为N.comb.前戈尔伯塔克斯。分布于老挝的8个新记录种分别是：圆头潜蝇A.Cirrifrons(Hemer，1984)、花斑隐翅虫Bathyphantes Floralis Tu&Li(2006)、禾谷隐翅虫Hylyphantes graminicola(Sundevall，1830)、无尾潜蝇属Nasoona asocialis、十字花叶蝉N.cross ifera(Thorell，1895)、中华水母(Nasoonaria sinensis Wunderlich&Song，1995)、花环潜蝇蛾(Neriene Birmanica，Thorell，1887)和尖尾潜蝇N.Oxycera Tu&Li，2006。老挝的线形蜘蛛动物群目前有15个物种，并且具有非同寻常的高度特异性。所有的物种，除了古北区的H.graminicola，都可能由东南亚或东方的自古恐龙代表。
Recent linyphiid collections from Laos as well as some additional specimens from Thailand and West Malaysia are examined. Six species and two genera are described as new to science: Bathyphantes paracymbialis n. sp., Nematogmus asiaticus n. sp., Theoa hamata n. sp.; Asiagone n. gen. is erected for Asiagone signifera n. sp. (type species) and A. perforata n. sp.; Laogone n. gen. is established for Laogone cephala n. sp. The following new synonyms are proposed: Gorbothorax Tanasevitch, 1998 n. syn. = Nasoona Locket, 1982; Paranasoona Heimer, 1984 n. syn. and Millplophrys Platnick, 1998 n. syn. = Atypena Simon, 1894; Gorbothorax ungibbus Tanasevitch, 1998 n. syn. = Oedothorax asocialis Wunderlich, 1974; Hylyphantes birmanicus (Thorell, 1895) n. syn. = H. graminicola (Sundevall, 1830). The following new combinations are proposed: Atypena cirrifrons (Heimer, 1984) n. comb. ex from Paranasoona; A. pallida (Millidge, 1995) and A. crocatoa (Millidge, 1995) both n. comb. ex Millplophrys; Nasoona asocialis (Wunderlich, 1974) n. comb. ex Oedothorax Bertkau, 1883; N. asocialis (Wunderlich, 1974), N. comata (Tanasevitch, 1998), N. conica (Tanasevitch, 1998), N. setifera (Tanasevitch, 1998) and N. wunderlichi (Brignoli, 1983), all n. comb. ex Gorbothorax. Eight linyphiid species are newly recorded from Laos: A. cirrifrons (Heimer, 1984), Bathyphantes floralis Tu & Li, 2006, Hylyphantes graminicola (Sundevall, 1830), Nasoona asocialis, N. crucifera (Thorell, 1895), Nasoonaria sinensis Wunderlich & Song, 1995, Neriene birmanica (Thorell, 1887), and N. oxycera Tu & Li, 2006. The linyphiid spider fauna of Laos currently contains 15 species and is unusually highly specific. All species, except the Palearctic H. graminicola, are probably represented by Southeastern Asian or Oriental autochthons.
