Parsimony analysis of morphological characters resolves a new species of Henicopinae (Lithobiomorpha) from Lord Howe Island as sister group to Australian and New Zealand species of Henicops Newport 1844. The diagnosis of Henicops is broadened to accommodate H. howensis sp. nov., which is documented with electron micrographs. Cladistic analyses with equal and implied weights resolve the New Caledonian Easonobius Edgecombe 2003 or Henicops brevilabiatus (Ribaut 1923), respectively, as sister to the Lord Howe + Australasian clade.
Five new species of the genus Trimalaconothrus, T. binodulus, T. duoaculeus, T. obesus, T. punctus and T. rectus, from South Africa are described. A key to species of the family Malaconothridae (Malaconothrus and Trimalaconothrus) of South Africa is given.
Six new records of the spiders from Taiwan are reported, which are, Araneus viridiventris Yaginuma 1969, Larinia fusiformis (Thorell 1877), Eriophora plumiopedella (Yin, Wang & Zhang 1987) comb. nov. (Araneidae); Thanatus miniaceus Simon 1880 (Philodromidae); Portia fimbriata (Doleschall 1859) (Salticidae) and Dolichognatha umbrophila Tanikawa 1991 (Tetragnathidae). The genera Portia, Thanatus and Dolichognatha are reported from Taiwan for the first time.
The large- and medium-sized species of the genus Cybaeus are reported based on the specimens collected from the Tohoku district, northern Honshu, Japan. Four new species, Cybaeus urabandai, C. yoshida, C. sasakii and C. miyagiensis, and three known species, C. nipponicus (Uyemura 1938), C. magnus Yaginuma 1958, and C. aquilonalis Yaginuma 1958, are described. Males of C. magnus and females of C. aquilonalis are described for the first time. Four new species occur only in the Tohoku district. Cybaeus magnus and C. aquilonalis are also distributed in Hokkaido. Cybaeus nipponicus is distributed over a wide range, not only Honshu but also Shikoku and Kyushu.
A new species of the spider family Thomisidae from Jianfeng National Nature Reserve, Ledong County, Hainan Province (Hainan Island), China, is described under the name of Lysiteles anchorus. The new species resembles Lysiteles ambrosii Ono 2001, from Bhutan and L. okumae Ono 1980 from Japan, but can be distinguished from these known species by having a pair of lateral pockets on epigynum and by the unique structure of male palp, especially the anchor-shaped embolus and the huge, retrolateral apophysis on tibia.
Zygiella x-notata (Clerck 1757) is newly recorded from Japan, based on the specimens collected from Yokohama Port, Kanagawa Prefecture, Honshu in 2003. The known distributional range of the species includes Europe and China, and North and South America possibly as the secondary introduction. It is likely that the present population found in Yokohama Port also originates from human transport.
