gilli, Zenarchopterus Smith [H. M.] 1945:432 [Bulletin of the United States National Museum No. 188; ref. 4056] East Indies. Syntypes: whereabouts unknown. Replacement name for Hemirhamphus brevirostris Günther 1866, preoccupied by Hemirhamphus brevirostris Cuvier 1829. Fowler (1934 [ref. 1416]) replaced Hemirhamphus brevirostris Günther 1866 before Smith (1945 [ref. 4056]) did so, but no one seems to have followed him, and the name Z. gilli has been widely accepted and should continue to be used for this species. •Valid as Zenarchopterus gilli Smith 1945 -- (Collette 1974:96 [ref. 12930], Collette 1982:265 [ref. 5497], Paxton et al. 1989:339 [ref. 12442], Talwar & Jhingran 1991:738 [ref. 20764], Kottelat et al. 1993:88 [ref. 23448], Larson & Williams 1997:350 [ref. 23967], Kottelat & Lim 1999:1097 [ref. 25899], Myers 1999:78 [ref. 23965], Collette in Randall & Lim 2000:600 [ref. 25122], Hutchins 2001:24 [ref. 25847], Allen & Adrim 2003:26 [ref. 26830], Kimura et al. in Kimura & Matsuura 2003:28 [ref. 27510], Collette 2004:21 [ref. 27583], Tan & Lim 2004:110 [ref. 27716], Paxton et al. 2006:739 [ref. 28994], Allen & Erdmann 2012:164 [ref. 31980], Larson et al. 2013:70 [ref. 32988], Kottelat 2013:297 [ref. 32989], Miesen et al. 2016:87 [ref. 34492], Fricke et al. 2018:105 [ref. 35805], Collette 2022:373 [ref. 39718], Jamandre 2023:162 [ref. 40455], Allen & Erdmann 2024:181 [ref. 40796]).
