Etymology: Malacoctenus: Greek, malakos = soft + Greek, kteis, ktenos = comb (Ref. 45335); zaluari: Named for Ricardo Zaluar Passos Guimarães, an ichthyologist friend who contributed to studies and descriptions of several reef fishes from the Brazilian coast.
Eponymy: Ricardo Zaluar Passos Guimarães of the Laboratório de Biodiversidade de Recursos Pesqueiros, Universidade Federal do Rio de Janeiro, Brazil, is the ‘ichthyologist friend’ of the authors. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 20; Dorsal soft rays (total): 11 - 12; Anal spines: 2; Anal soft rays: 19 - 21. This species is distinguished from its southwestern Atlantic congeners by the following set of characters: D XX,11-12 (rarely XXI,10); A II,19-21; pectoral rays 14; length of third pelvic ray contained 2.5 to 3.0 times in second pelvic-fin ray; lateral-line scales 51-53; total nuchal cirri 12-16; presence of pre-dorsal scales and pre-pectoral scales, when present are considerably smaller than scales on body; breast usually fully scaled on males, often naked on females; one pore, rarely absent, extend from preopercular canal onto opercle. Colouration: body with 5-6 saddle-like bars that do not extend on dorsal fin; two thin white bands on upper lip usually extending to snout (Ref. 123106).
Cross section: oval.
Cross section: oval.
Occurs in shallow reefs and tide pools, usually in clear waters where it feeds on small benthic invertebrates (Ref. 123106).
