Rhabdolichops nigrimans can further be distinguished from R. lundbergi by having: a longer body (maximum total length 419 vs. 233 mm TL; n = 15 for each species); an exaggeratedly scaly appearance of anterior epaxial body surface due to chromatophores concentrated along outer scale margins; larger teeth on premaxilla, mesopterygoid and dentary; and more numerous teeth on premaxilla (20-25 vs. 18-20), mesopterygoid (11-13 vs. 8), and dentary (25-34 vs. 12-13; n = 2 adults for each species); and sexual dimorphism of the caudal appendage (tail) length in which mature males possess a longer caudal appendage than mature females (mean CA 44 ± 2.9% vs. 38 ± 3.2%; n = 5 each) (Ref. 55969).
