macrostomus, Gobiopsis Steindachner [F.] (ex Heckel) 1861:291, Pl. 1 (fig. 6) [Sitzungsberichte der Mathematisch-Naturwissenschaftlichen Classe der Kaiserlichen Akademie der Wissenschaften v. 42 (for 1860); ref. 4205] Mumbai, India. Syntypes: NMW 29594-96 (1, 1, 1). Appeared as Gobiopsis macrostomus m. = Gobius macrostomus Heckel (manusc.)"; Steindachner apparently responsible for description (m = mihi). The gender of Gobiopsis is masculine; Kottelat (2013) suggests that this is correct (macrostomus, i.e., an indeclinable noun), rather than a mistake (macrostoma). •Valid as Gobiopsis macrostoma Steindachner 1861 -- (Talwar & Jhingran 1991:937 [ref. 20764], Wu in Pan et al. 1991:486 [ref. 23876], Zhu 1995:183 [ref. 25213], Rainboth 1996:201 [ref. 22772], Larson & Williams 1997:368 [ref. 23967], Larson in Randall & Lim 2000:638 [ref. 25122], Larson & Murdy 2001:3598 [ref. 26293], Manilo & Bogorodsky 2003:S119 [ref. 27377], Ataur Rahman 2003:327 [ref. 31338], Hoese & Larson 2006:1658 [ref. 29097], Larson et al. 2008:149 [ref. 29532], Shibukawa 2010:97 [ref. 30809], Allen & Erdmann 2012:977 [ref. 31980], Larson et al. 2013:199 [ref. 32988], Habib & Islam 2020:Supplementary table p. 14 [ref. 38321], Parenti 2021:173 [ref. 38603], Taki et al. 2021:438 [ref. 39830]). •Valid as Gobiopsis macrostomus Steindachner 1861 -- (Kottelat 2013:409 [ref. 32989], Shibukawa in Kimura et al. 2018:261 [ref. 36460], Larson 2022:101 [ref. 39971], Endruweit 2024:83 [ref. 41040] with author as Heckel).
