Description: This genera has a posterier nostril located near anterior nostril. Barbels are ribbon shaped, with a mandibular and a mental pair on lower jaw. 6 pelvic fin rays. There are two species in this genus. L. hexanema and L. longibarbus. Compared to L. laides, this species differs in having a shorter anal fin base (34.8-37.9 SL versus 38.6-41.5% SL) with less anal fin rays (39-42 versus 41-47), a larger eye (eye diameter 28.6-38.5 HL versus 20.1-23.6% HL) and a smaller interorbital distance ( 37.9-47.3 HL versus 47.0-55.6%). Found in large rivers and feeds on small fishes. Oviparous, eggs are unguarded. Remarks: Laides hexanema is still listed in Fishbase as being in the Schilbeidae family but it is updated in Eschmeyer's Catalog of Fishes as the current status of being in the Ailiidae family.
