dhanashorii, Rhynchobdella Hora [S. L.] 1921:205, Pl. 9 (fig. 2) [Records of the Indian Museum (Calcutta) v. 22 (pt 3, no. 19); ref. 2202] Dhanashori stream, about 1 mile from Dimapur, Assam, India.

See Das 2003:370 [ref. 27706]. •Questionably a synonym of Macrognathus aral (Bloch & Schneider 1801) -- (Talwar & Jhingran 1991:1026 [ref. 20764], Menon 1999:301 [ref. 24904] as dhanshorii, Kottelat 2013:311 [ref. 32989]). Current status: Uncertain as Macrognathus aral (Bloch & Schneider 1801). Mastacembelidae. Habitat: freshwater.

jammuensis, Macrognathus Malhotra [Y. R.] & Dutta [P. S.] 1975:153 [Proceedings of the National Academy of Sciences, India. v. 45 (B) (3); ref. 33270] Gadigarh, Jammu, India. Dept. Biosci. Univ. Jimmu. •Synonym of Macrognathus aral (Bloch & Schneider 1801) -- (Talwar & Jhingran 1991:1026 [ref. 20764], Menon 1999:301 [ref. 24904], Kottelat 2013:311 [ref. 32989]).

ocellata, Rhynchobdella Cuvier [G.] in Cuvier & Valenciennes 1832:445, [Pl. 239?] [Histoire naturelle des poissons; ref. 1000] Puducherry, India. Syntypes: MNHN A-4810 (1, dry), A-4811 (1, dry). Apparently an unneeded new name for and objective synonym of Ophidium aculeatum Bloch 1786 [now Macrognathus aculeatus (Bloch 1786)]. The plate (Pl. 239) that is referenced to the name Rhynchobdella ocellata (in two places) bears the name Rhynchobdella aral, which also might be available from this work and independent of Rhynchobdella aral Bloch & Schneider 1801; needs research. See also Macrognathus ocellats Hamilton 1822. •Objective synonym of Macrognathus aral (Bloch & Schneider 1801) -- (Kottelat 2013:311 [ref. 32989]). Current status: Synonym of Macrognathus aculeatus (Bloch 1786). Mastacembelidae. Habitat: freshwater.
