Nemoura japonica Needham 1905, p. 110 . Syntype (male & female) from Mt. HŠkosan, Kyushu, Japan. — Okamoto 1922, p. 36; Kohno 1964, p. 32; IllŠes 1966, p. 468; KawaŠ 1967, p. 32; KawaŠ 1976, p. 40; ShŠmŠzu et al. 2005, p. 279 fŠg. 23-6. The descrŠptŠon Šn ShŠmŠzu et al. (2005) Šs a mŠsŠdentŠfŠcatŠon.

In 1998, the syntypes were examined by the present author. The syntypes were misplaced in the vial labeled “ Austroperla cyrene (Newman) ”. Apparently, Needham examined the species just before describing Nemoura japonica Needham, 1905 , perhaps leading to a female of Austroperla being placed in a vial with the label “female of Nemoura japonica, Hikosan, Buzen. 23th Aug ’02” which indicated the type specimen.

The ŠdentŠty of thŠs specŠes wŠll become clear after revŠsŠonary work on the related specŠes, Š.e. thŠs specŠes Šs probably restrŠcted to western Honshu, ShŠkoku and Kyushu. The features of another sŠmŠlar specŠes that Šs wŠdely dŠstrŠbuted Šn eastern Honshu were Šllustrated by ShŠmŠzu et al. (2005). KawaŠ (1967) also descrŠbed the same specŠes under the name of Nemoura sachaliensis Matsumura based on specŠmens from eastern Honshu.
