Five species, Octonoba alishanensis sp. nov., O. kuanwuensis sp. nov., Uloborus lushanensis sp. nov., U. taiwanus sp. nov.and U. wulaiensis sp. nov. are new to science. Five species, Miagrammopes bifurcatus Dong, Yan, Zhu& Song, 2004, O. biforata Zhu, Sha & Chen, 1989, O. senkakuensis Yoshida, 1983b, U. penicillatoides Xie, Peng, Zhang, Gong & Kim, 1997 and U. walckenaerius Latreille, 1806 are newly recorded in Taiwan. The males of O. albicola Yoshida 2012 and O. lanyuensis Yoshida, 2012 were described for the first time. Octonoba varians (Bösenberg & Strand, 1906) was excluded from the spider fauna of Taiwan, and Uloborus formosanus Yoshida, 2012 was considered a synonym of U. penicillatoides Xie, Peng, Zhang,Gong & Kim, 1997. The chromosome numbers and sex-determining mechanisms of five species belonging to four genera of Uloboridae in Taiwan are recorded in this study. Four of the five are recorded for the first time. The chromosome numbers of male (M) and female (F) of O. albicola, O. spinosa and U. walckenaerius are 2n = 18M/ 20F, and those of Philoponella prominens 2n = 34M/36F. The sex-determining mechanisms of these four species are X1X2O type. The chromosome numbers of Z. geniculata are 2n =9M/10F, and the sex-determining mechanism is XO type. The diversity of chromosome numbers and sex-determining mechanism would be more clear as the chromosome data of spiders accumulate. The results of this study will increase the basic knowledge of diversity and natural behaviors of Uloboridae in Taiwan, and also serve as a foundation for the research of chromosomal evolution.性別決定機制染色體新記錄種新種sex-determining mechanismchromosomenew recordnew species
