Holotype: ZSI FF 8218, 88.1 mm SL; India; Mizoram, Kaladan River, in the vicinity of Kawlchaw village; 23 ° 28 ’ 29 ” N; 92 ° 23 ’ 27 ” E; Lalramliana et al., 24 Nov. 2015. Paratypes: ZSI FF 8219, (2), 91.2 – 94.4 mm SL; PUCMF 17017 (5), 85.8 – 111.4 mm SL; PUCMF 17018 (3), 90.0 – 95.5 mm SL; (dissected and preserved in glycerin with thymol) data as holotype. Diagnosis. Cabdio crassus markedly differs from all other valid species of Cabdio (Fig. 3) by having the venter keeled from mid-point of chest, between the posterior base of the pectoral fin and along the abdomen up to the anus, and possessing 11 ½ – 12 ½ (vs. 7 – 9) branched anal-fin rays. It is further distinguished from C. morar and C. ukhrulensis by possessing more lateral-line scales (45 – 51 vs. 38 – 42 in C. morar and 35 – 37 in C. ukhrulensis), more predorsal scales (20 – 23 vs. 17 – 18 in C. morar and 14 in C. ukhrulensis) and more lateral transverse scales (½ 7 / 1 / 3 ½ vs. 5 / 1 / 2 in both C. morar and C. ukhrulensis). It also differs from C. jaya in having fewer lateral-line scales (45 – 51 vs. 52 – 60), more lateral transverse scales (½ 7 / 1 / 3 ½ vs. 5 / 1 / 3) and more pharyngeal tooth-rows (3 vs. 2). Descrip
