Spiders of the genus Cybaeus are diverse in Japan and exhibit extensive morphological variation of their genitalia among species. Among Japanese Cybaeus, several species possess an elongated embolus in males and elongated spermathecae in females. Here, we describe Cybaeus iharai sp. nov. from Nagano Prefecture, central Honshu, Japan, which possesses a short embolus in males and short copulatory ducts in females. In addition, DNA sequences of the new species were obtained for future phylogenetic analyses.

Taxonomic accounts of two species belonging to the subfamily Coelotinae from Japan are reviewed. Iwogumoa portus Nishikawa 2009 originally described from Osaka, Japan and Coelotes plancyi Simon 1880 described from Beijing, China are considered to be conspecific. Therefore the former is synonymized with the latter, and C. plancyi is transferred to the genus Iwogumoa Kishida 1955. Coelotes inabaensis Arita 1974 described from Tottori, Japan is placed under the genus Dichodactylus Okumura 2017.
