Okinawicius Proszynski 2016

GenusOkinawiciusPrószyński, 2016 Okinawicius Prószyński, 2016: 22. Nepalicius Prószyński, 2016: 21. Syn. nov. Type species. Pseudicius okinawaensis Prószyński, 1992; type locality Okinawa. Diagnosis and description. See Prószyński (2016). Composition. This genus currently includes 12 species: Okinawicius daitaricus (Prószyński, 1992) (♀); O. daoxianensis (Peng, Gong & Kim, 2000), comb. nov. (♂); O. delesserti (Caporiacco, 1941) (♂); O. modestus (Simon, 1885) (♀); O. nepalicus (Andreeva, Hęciak & Prószyński, 1984), comb. nov. (♂ ♀); O. okinawaensis (Prószyński, 1992) (♀); O. seychellensis (Wanless, 1984), comb. nov. (♂ ♀); O. sheherezadae (Prószyński, 1989) (♀); O. shirinae (Prószyński, 1989) (♂); O. sindbadi (Prószyński, 1989) (♂); O. tekdi Tripathi & Kulkarni, 2024 (♂ ♀); O. tokaraensis (Bohdanowicz & Prószyński, 1987) (♂ ♀). Comments. Both Nepalicius and Okinawicius were described by Prószyński (2016). They are considered to be congeneric because the newly discovered females of N. nepalicus (the generotype of Nepalicius) share consistent habitus and epigyne with O. okinawaensis (the generotype of Okinawicius, known only from females), especially the copulatory ducts that form several coils in a plane almost perpendicular to the vertical axis. Thus, Nepalicius is proposed as a synonym of Okinawicius. We act as First Revisor per ICZN (1999). Okinawicius daoxianensis (Peng, Gong & Kim, 2000), comb. nov. is transferred due to it having the round tegulum encircled by embolus and with dorsal ramus of retrolateral tibial apophysis reduced to a triangular protuberance, which is consistent with O. nepalicus. As Yang et al. (2024) mentioned, some Afraflacilla species, only known by males, may also belong to Okinawicius. Moreover, the relationship between Okinawicius and Afraflacilla also needs further attention.
