A crab spider species, Xysticus crispabilis Song & Gao, 1996 (Araneae: Thomisidae), originally described from Anhui, China based on a single male specimen, is newly recorded from Japan. This study represents the second specimen-based record of the species since its original description. Detailed redescriptions of genital morphology, coloration and markings of the male are provided based on fresh material. The previously unknown female is described for the first time. In addition, genital images of the holotype, DNA barcoding data, preliminary molecular phylogeny, and ecological notes are presented.
Suzuki et al. (Wed,) studied this question.
