Type species: Bagrus (Sciades) emphysetus Müller & Troschel, 1849 .

Diagnosis

Lateral horn of lateral ethmoid acute (11, 1> 0), reversed in Sciades couma and Sciades herzbergii ; fenestra delimited by lateral ethmoid and frontal very small or indistinct (17, 1> 0); orbitosphenoid and pterosphenoid lateral expansions very narrow and long (65, 0> 1), reversed in Sciades couma and Sciades herzbergii ; parasphenoid very wide in ventral view (66, 0> 1); otic capsule of moderate size, limited by prootic, pterotic, and exoccipital (70, 2> 1), reversed in Sciades couma and Sciades herzbergii ; space between transcapular process and otic capsule very large (89, 1> 0), reversed in Sciades couma and Sciades herzbergii ; one-half or less of interopercle posterior part contacting ventral margin of opercle (131, 1> 0), reversed in Sciades couma and Sciades herzbergii ; Müllerian ramus distal third straight (208, 1> 0).

Ambiguous optimization: Mesethmoid median portion moderately wide (2, 1> 2); autopalatine posterior portion conspicuously compressed (106, 0> 1); articulation of autopalatine with lateral ethmoid mesoposteriorly oriented (110, 0> 1); lateral margin of premaxilla with a very conspicuous concavity (123, 1> 2); sesamoid bone I very long and subrectangular (145, 2> 3); sesamoid bone II irregularly elongate (146, 0> 1); first external branchiostegal ray proximally narrow and distally broad (147, 1> 0); reversed in Sciades couma and Sciades herzbergii ; complex formed by anterior and median nuchal plates shield-like (218, 0> 1); reversed in Sciades couma , Sciades herzbergii , and Sciades passany ; nuchal plate overlaying parieto-supraoccipital (220, 1> 2); groove connecting posterior nostrils present (233, 0> 1); reversed in Sciades parkeri and Sciades proops .
