03F087F4FA1CFF84FC60F88DFE7AF884.taxon	discussion	Nemoura misnosa [sic], Shimizu 1997 a, p. 532, found syn. of Rhabdiopteryx japonica Okamoto 1922. This species was treated as a junior homonym of Nemoura japonica Needham 1905 and renamed as Nemoura misnoma by Claassen (1936). In Matsumura (1904) the date of publication was specified as 10 September 1904 and included a description and illustration of the characters. Shimizu (1997 a) found that this species was synonymous with Taenionema japonicum (Okamoto 1922). Shimizu (1997 a) attempted to designate the lectotype of Nemoura misnoma with the syntype of Nemoura japonica Matsumura in his collection of Hokkaido University, and the lectotype is now redesignated for Nemoura japonica Matsumura 1904.	en	Shimizu, Takao (2016): Dates, Validity And Spelling Of Japanese Stoneflies (Plecoptera) Described By Shonen Matsumura.

03F087F4FA1CFF84FC60F88DFE7AF884.taxon	description	According to the rule of priority in zoological nomenclature, both Nemoura japonica Needham 1905 and Nemoura misnoma Claassen 1936 must be rejected, as a primary homonym and as an unnecessary replacement name, respectively. Nemoura japonica Matsumura, 1904 is a senior synonym of Rhabdiopteryx japonica Okamoto 1922 and has since been transferred to the genus Taenionema. Taenionema japonicum (Matsumura 1904) is the valid name of the species, and T. japonicum (Okamoto 1922) is its secondary junior homonym. While the late Dr. Hanjiro Okamoto (1882 - 1960) studied under the late Prof. Shonen Matsumura, Okamoto (1922) unfortunately ignored the description of the present species. It seemed to be thought that Matsumura’s works were scientifically invalid, except his work in 1911, in those days in Japan.	en	Shimizu, Takao (2016): Dates, Validity And Spelling Of Japanese Stoneflies (Plecoptera) Described By Shonen Matsumura.

03F087F4FA1DFF84FC5DFF66FC7AFB13.taxon	description	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. 23 th 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.	en	Shimizu, Takao (2016): Dates, Validity And Spelling Of Japanese Stoneflies (Plecoptera) Described By Shonen Matsumura.

03F087F4FA1DFF87FC91FAA0FD27FD68.taxon	description	This species is now treated as a nomen dubium and the status is still questionable. Matsumura (1907) described the characteristics of this species as follows: body dark brown, vertex of head and median line of prothorax yellow; wings greyish white and sub- hyaline, rather reduced venation, bearing 8 crossveins between media and cubitus 1, and 5 cross- veins between cubitus 1 and 2; legs and cerci dark yellow; body length 9 - 12 mm and wing expanse 27 - 33 mm long. Matsumura (1907) probably measured from dry specimens. Also, he commented that this species was as common as Nemoura japonica Matsumura at that time. The color looks similar to that of the genus Stavsolus, but no information on the locality is given in his description. Still, the identity of this species cannot be settled without his specimens.	en	Shimizu, Takao (2016): Dates, Validity And Spelling Of Japanese Stoneflies (Plecoptera) Described By Shonen Matsumura.

03F087F4FA1EFF87FEEEF974FB0AFCC4.taxon	discussion	Matsumura (1931 a, b) dŠd not state that the name was new Šn the Šllustrated book, and no earlŠer publŠcatŠon has been found among hŠs works. The date of publŠcatŠon of thŠs specŠes Šs probably 1931. IncŠdentally, the orŠgŠnal spellŠng of the name Šs hirayamai. However, IllŠes (1966) and KawaŠ (1967) spelled the name hirayamae. IllŠes (1966) erroneously suggested that hirayamai Šn Claassen (1940) was a mŠsspellŠng.	en	Shimizu, Takao (2016): Dates, Validity And Spelling Of Japanese Stoneflies (Plecoptera) Described By Shonen Matsumura.
