Abstract
Spider collections from Laos, especially from Oudomxai and Bolikhamsay Provinces, are investigated. One new species of the family Corinnidae is described: Serendib muadai spec. nov. (male, female) from Bolikhamsay Province. Seventeen species are newly recorded from Laos: Macrothele bannaensis Xu & Yin 2001, Cyclocosmia siamensis Schwendinger 2005, Pseudanapis parocula (Simon 1899), Neriene macella (Thorell 1898), Tetragnatha hasselti Thorell 1890, Cyrtophora cylindroides (Walckenaer 1841), Larinia phthisica (L. Koch 1871), Cheiracanthium insigne O. Pickard-Cambridge 1874, Corinnomma severum (Thorell 1877), Oedignatha scrobiculata Thorell 1881, Pranburia mahannopi Deeleman-Reinhold 1993, Cebrenninus rugosus Simon 1887, Bianor incitatus Thorell 1890, Hasarius adansoni (Audouin 1826), Hyllus diardi (Walckenaer 1837), Thiania bhamoensis Thorell 1887, and Thyene imperialis (Rossi 1846). Further records are listed, and new records and descriptions from papers published recently on material collected in Laos are reported. The total number of Lao spider species amounts currently to 225 species. Beside true spiders, the second record of Typopeltis magnificus Haupt 2004 is recorded from Laos.
