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. Etymology: The genus name Laides: –ides, descendant of: replacement name for Lais Bleeker 1858, preoccupied by Lais Gistel 1848 in Tunicata (Lais is Sundanese name for L. hexanema). The specific name hexanema: hexa-, six; nema, thread, referring to the three pairs of fleshy barbels. Remarks: Laides hexanema is still listed in Fishbase as belonging to the Schilbeidae family but it is updated in The Catalog of Fishes as the current status of being a member of the Ailiidae family.
