Short description
Identification keys | Morphology | Morphometrics
Distinguished from other genera by having the following characteristics: moderately developed cephalic sensory canals; separated right and left gill membrane, attachment points of each side very close together, gill opening extending to vertical from posterior end of preoperculum and posterior edge of eye; incompletely fused first and second epurals, consequently two epurals present; long and ribbon-like shaped gill rakers on lower half of outer surface of first gill arch without spine; absence of lateral line; absence of connection between oculoscapular and preopercular canals; absence of furrow from mid-lateral scales; normal shaped sensory papilla, without barbel like projections; interorbital width nearly equal to eye diameter; cycloid predorsal scales, reaching posterior part of interorbital space; branched 5th pelvic fin ray; absence of distal radial of first-dorsal fin element; presence of suborbital bone; absence of lateral extrascapula; prevomerine teeth absent; ventral transverse shelf on posterior half of urohyal present; gill rakers separated on inner part of 4th ceratobranchial; presence of anterior projection on anterior tip of metapterygoid; absence of overlap with lower part of ectopterygoid and quadrate (Ref. 92840).
