Rhopalopsole sinuacercia Sivec & Shimizu , nom. nov.

Rhopalopsole longicercia Sivec & Shimizu 2008:89 . No holotype designated

Material examined. Holotype ♂, 5♂, 5♀ paratypes, Japan, Shizuoka Prefecture, Kiyozasa Pass , 24 May 1986, M. Satô (P. Zwick collection). Additional paratypes all from Japan: Oyana-gawa, 800 m, Kaji Zawa-cho, Yamanasi, 29 May 1993, T. Hattari, 3♂, 3♀ (Lake Biwa Museum). Kanagawa, Yamakita-machi, Yoki-zawa, small tributary, 10 May 1996, T. Shimizu, 8♂, 2♀ ( Lake Biwa Museum ) . Shizuoka Prefecture, Haruno-San , 26 May 1986, M. Satô 4♂ (P. Zwick collection) .

Detailed descriptions and figures are available in Sivec et al. 2008, pages 89-91. The new name is required because the original descriptions for adults of this species are presented as a species complex description without designation of a holotype. An additional problem occurs in selection of “longicercia” as the original specific epithet because R. longicerca Kawai 1968 is rendered as R. longicercia Kawai on page 101 in Sivec et al. (2008).

Etymology. The species name refers to the slightly sinuate curvature of the cerci in dorsal and lateral aspect.

Diagnosis. Males of this species have a relatively long, acute epiproct, relatively short, unforked lateral processes with swollen bases on tergum 10, long sinuate cerci with terminal, inwardly-directed spine, and an unusual, warty process set near the posteromedian point of tergum 9. This combination of characters is otherwise unknown ( Sivec et al. 2008), however as Sivec et al. (2008) indicate, additional, closely related species are expected.
