Gen. Okinawicius Prószyński, 2016 , gen. n.

Figures 7E–K , 8C–E

Type species. Pseudicius okinawaensis Prószynski, 1992 .

Documentation studied. Comparative diagnostic drawings of 11 species in Prószyński (2016a) and original literature.

Etymology. Name combines words Okinawa and Icius , grammar gender assumed masculine.

Diagnosis. Share mutual diagnostic characters of PSEUDICIINES: lateral, subocular row of about 10 short bristles on protuberances, modified tibia of robust leg I, flattened body and characteristic color pattern.

Female differs by prominent pockets on the surface of epigyne, which are unusually long and prominent. There is a pair of medial depressions on epigyne, with indistinct copulatory openings, visible only after clearing of epigyne. Striking difference is provided by a flat spiral of several concentric membranous coils of copulatory ducts, in a plane parallel to the surface of epigyne ( Figs. 7K , 8D ), visible after staining in Chlorazol Black E. These join narrow and long, sclerotized spermathecae near the prominent armature of scent opening (which in O. modestu s is long, chimney-like). Sclerotized parts of these structures is comparable to Nepalicius .

Males (matching require confirmation). Embolus arise laterally from bulbus, either in its mid-lenght, or posteriorly. Tibial apophysis with stumpy rami, two or three ( Figs. 7K , 8D )

Remarks. Females of O. sheherezadae and males of Pseudicius sindbadi were collected in the same day – April 11th, 1980, in the same locality Thanomah in Saudi Arabia, at the same altitude 2140 m., and by the same collector W. Buettiker, since Salticidae in deserts are sparse and rarely collected, there is good chance that they may match, therefore belong to the same species. If so, morphologically similar male of Pseudicius shirinae from Wadi Harth may also belong to Okinawicius . The placement of Okinawicius [?] vankeeri (Metzner, 1999) is tentative, male palp resembling Okinawicius shirinae and O. delesserti , the ducts of epigyne rather Psenuc , or even Pseudiciu s, that problem pending further studies.

Suguro &Yahata (2014: 63 (2): 87-97) proposed to synonymize Pseudicius tokaraensis and P. okinawaense ( Fig. 7G ), misinterpreting epigyne and internal structures of epigyne of these species ( Figs. 7E – F, H – I ), that synonymy is rejected hereby and both species are sustained as valid and separate, I transfer them now to the genus Okinawicius Prószyński, 2016 (here described).

Composition. The following species are transferred from the genus Pseudicius Simon, 1885 : Okinawicius daitaricus (Prószynski, 1992) , comb. n., O. delesserti (Caporiacco, 1941) , comb. n., O. modestus (Simon, 1885) comb. n., O. okinawaensis (Prószynski, 1992) comb. n., O. sheherezadae [ + sindbadi ? conspecific?] ( Prószynski, 1989) comb. n., O. shirinae ( Prószyński, 1989) comb. n., O. tokaraensis (Bohdanowicz, Prószynski, 1987) comb. n., Okinawicius [?] vankeeri (Metzner, 1999) comb. n.
