Description of a new species of Cybaeus (Araneae: Cybaeidae) from central Honshu, Japan

A new spider species, Cybaeus daimonji, from Kyoto, western-central Honshu, Japan is described based on both sexes. The shape of epigyne indicates that this new species is close to C. communis Yaginuma, 1972, C. kirigaminensis Komatsu, 1963, C. maculosus Yaginuma, 1972 and C. shinkaii (Komatsu, 1970), which are distributed in eastern to central Honshu. Nuclear internal transcribed spacer 1, 28S ribosomal RNA and histone H3 as well as mitochondrial cytochrome c oxidase subunit I, 12S ribosomal RNA and 16S ribosomal RNA sequences of the new species are provided for future phylogenetic studies.
