The prevalence of Toxoplasma gondii infection in free-ranging cats on Tokunoshima Island was assessed by testing 125 serum samples using anti-T. gondii IgG indirect enzyme-linked immunosorbent assay. The overall seropositivity rate was 47.2% (59/125). Seropositivity rates in cats with body weight >2.0 kg (57.4%) were significantly higher than in those with body weight ≤2.0 kg (12.5%, P<0.01). Analysis of the number of seropositive cats by settlement revealed the presence of possibly-infected cats in 17 of 23 settlements, indicating the widespread prevalence of T. gondii on the island. This is the first study to show the seroprevalence of T. gondii in free-ranging cats on Tokunoshima Island. The information revealed in this paper will help to prevent the transmission of T. gondii among cats and also in both wild and domestic animals and humans on the island.

Japanese spiders of the genus Dolomedes are revised and its phylogeny is inferred by mt-DNA. Dolomedes japonicus Bösenberg & Strand 1906 and D. angustivirgatus Kishida 1936 are removed from the synonymy. Dolomedes fimbriatoides Bösenberg & Strand 1906 and D. hinoi Kayashima 1952 are newly synonymized with D. sulfureus L. Koch 1878, and D. stellatus Kishida 1936 is synonimized with D. japonicus. Two new species, D. fontus and D. silvicola are described. Relative leg length and proportion of male palpal tibia are considered as good keys to indentify Dolomedes spiders, whose genital organs closely resemble one another. Dolomedes sulfureus and D. silvicola, often found on vegetation, have much longer legs and male palpal tibia than their relatives that inhabit near water and run on water surface or hide under water when disturbed. Molecular phylogenetic analysis using mt-COI revealed the following; ((((raptor, yawatai), japonica), orion), (((angustivirgatus, sulfureus), fontus), (silvicola, saganus)), horishanus).
