Japanese salticid species of the genus
Tasa and a part of the genus
Pseudicius are taxonomically revised by morphological investigation and molecular analysis using partial sequencing data of mt-DNA COI gene. As a result, the female of
Pseudicius koreanus Wesolowska 1981 and the male of
Tasa nipponica Bohdanowicz & Prószynski 1987 are identified as the same species. Therefore,
T. nipponica is newly synonymized with
P. koreanus, and
P. koreanus is transferred to the genus
Tasa, due to its male genital morphology. The male of
P. koreanus sensu Bohdanowicz & Prószynski (1987) is identified as the male of
Pseudicius tokaraensis (Bohdanowicz & Prószynski 1987). Incidentally,
P. okinawaensis Prószynski 1992 is newly synonymized with
P. tokaraensis. Additionally,
Pseudicius kimjoopili (Kim 1995) comb. nov. is newly recorded from Japan. The male of this species is described for the first time. This species is transferred from the genus
Helicius. After these taxonomic revisions, Japanese
Pseudicius species are following three for the present:
P. kimjoopili,
P. tokaraensis and
P. vulpes. These three can be easily distinguished from each other by their general appearances or genital morphologies.
