Holotype (unique): AMS IA.7288. •Valid as Coius campbelli (Whitley 1939) -- (Roberts & Kottelat 1994:258 [ref. 21569] with range as Gulf of Papua drainages and coastal waters of New Guinea, Carpenter 2001:2945 [ref. 26101]). •Synonym of Datnioides quadrifasciatus (Sevastianov 1809) -- (Allen 1991:138 [ref. 21090] [but see quadrifasciatus]). •Valid as Datnioides campbelli Whitley 1939 -- (Allen et al. 2008:119 [ref. 30265]).

hexazona, Lobotes Bleeker [P.] 1850:9 [Natuurkundig Tijdschrift voor Nederlandsch Indië v. 1 (no. 1); ref. 16884] Bandjarmasin, Borneo, Indonesia.

Treated as a synonym of Datnioides quadrifasciatus (Sevastianov 1809) or Coius quadrifasciatus (Sevastianov 1809), but quadrifasciatus is apparently not available and polota would be valid as Coius polota. •Synonym of Datnioides quadrifasciatus (Sevastianov 1809) -- (Roberts 1989:165 [ref. 6439]). •Synonym of Coius quadrifasciatus (Sevastianov 1809) -- (Roberts & Kottelat 1994:258 [ref. 21569], Ataur Rahman 2003:351 [ref. 31338]). •Valid as Datnioides polota (Hamilton 1822) -- (Ataur Rahman 1989:325 [ref. 24860] as Datnoides). •Valid as Datnioides polata (Hamilton1822) -- (Allen et al. 2008:119 [ref. 30265], Kottelat 2013:344 [ref. 32989], Sulaiman et al. 2018:45 [ref. 35802], Suresh et al. 2018:232 [ref. 36495], Ng et al. 2019:538 [ref. 36606], Taki et al. 2021:364 [ref. 39830]).
