lacustre, Crossostoma Steindachner [F.] 1908:110 [Anzeiger der Kaiserlichen Akademie der Wissenschaften, Wien, Mathematisch-Naturwissenschaftliche Klasse v. 45 (no. 8) (for 5 Mar. 1908); ref. 18802] Taiwan. Syntypes: (several) NMW 47138 (3), 48680 (3), 48682-83 (3, 3), 48690 (4). Type catalog: Ho & Shao 2011:31 [ref. 31432]. Apparently a replacement name for Homaloptera formosanum Steindachner 1908, preoccupied by Homaloptera formosana Boulenger 1894. See account of Formosania; the genus Crossostoma is preoccupied. The genus Formosania is feminine, therefore mandatory correction to lacustris. •Valid as Crossostoma lacustre Steindachner 1908 -- (Watanabe 1983:106 [ref. 8266], Tzeng & Shen 1982:164 [ref. 8410], Tzeng et al. 1990:11 [ref. 16723], Zhu 1995:132 [ref. 25213], Chen & Tang in Yue 2000:466 [ref. 25272], Tang & Chen 2000:5 [ref. 25445], Chen et al. 2002:239 [ref. 26535], Zhang & Wang 2011:87 [ref. 31283]). •Valid as Formosania lacustris (Steindachner 1908) [sometimes as lacustre] -- (Chen & Fang 2009:185 [ref. 30109], Ho & Shao 2011:31 [ref. 31432], Kottelat 2012:61 [ref. 32367], Zhang et al. 2016:159 [ref. 34477], Sun et al. 2023:219 [ref. 40543] as lacustre).
