Plectocolea yunnanensis

According to Bakalin (2013: 132) this new species from the Solenostoma truncatum ( Nees 1830: 29) Váňa & Long (2009: 509) complex is closely related to Plectocolea boninensis ( Horikawa 1934: 142) Hattori (1944: 37) , Plectocolea granulata ( Stephani 1897: 100) Bakalin (2013: 132) and Plectocolea shinii ( Amakawa 1970: 156) Bakalin (2013: 132) , all of which were synonymized by Váňa and Inoue (1983: 132, 134) with the very common and variable Solenostoma truncatum . Bakalin (l.c.: 133) with his narrow species concept of Solenostoma accepted the three above mentioned species as separate taxa and regarded the decision of Váňa & Inoue (1983: 132, 134) as “premature” and “additional studies including molecular analyses are needed to resolve this question.” We agree with this reasoning, yet we maintain there is no new evidence at hand to warrant recognition of these taxa However, Bakalin’s new species is fully identical with Solenostoma sikkimense , a species not at all mentioned in the text.
