( Figs. 6A–6H )

Trichosetodes ujiensis Akagi 1960 , 88–89, male, Honshu (Kyoto).

Setodes ujiensis: Schmid 1987 , 136; Kumanski 1991, 53–55, female, Korea; Uenishi 1993, 82; Nozaki & Nakamura 2005, 226, male, female, Honshu (Shimane); Kimura et al. 2007, 167, Honshu (Nagano); Katsuma 2009, 44–46, male, female, Honshu (Shimane).

Adult. Specimens in alcohol. Head and body very pale. Forewings each 5.0 mm long (n = 2) in male, 6.0 mm (n = 1) in female. Wing venation typical for genus.

Male genitalia. Segment IX longitudinally short dorsally, long ventrally with many strong setae. Segment X sickle-like in lateral view, divided into two long lobes, gradually curved outward midway in dorsal view, each apex notched in lateral view; lower margin of each lobe with long acute process midway. Preanal appendages oval in lateral and dorsal views, with many short setae. Inferior appendages each divided into four branches; upper-most branch, upper-middle branch, and lower-middle branch similar to those of S. hinumaensis ; each lower-most branch shorter than that of S. hinumaensis , about 1.3 times as long as segment IX, curved dorsocaudad in lateral view. Phallus similar to that of S. hinumaensis , but pair of sclerotized lobes of phallicata relatively small, weakly projecting posterodorsad in lateral view. Paramere spines absent.

Female genitalia. Segments VIII, IX, preanal appendages and lamellae similar to those of S. hinumaensis , but anal opening not sclerotized, appearing on basal 1/4 of ventral surface of segment X. Gonopod plate situated on posteroventral margin of segment IX, dark pigmented.

Specimens examined. Same as Katsuma (2009).

Immature stages. Unknown.

Distribution. Honshu (central to western), Korea.

Japanese name. Uji-seto-tobikera.

Remarks. This species belongs to the Setodes hungaricus Species Group ( Schmid 1987) and is the sister species of S. hinumaensis ( Katsuma 2009) .
