Etymology: Hypoplectrus: Greek, hypo = under + Greek, plektron = sting, spur (Ref. 45335); randallorum: Named for Helen and John E. Randall, who first recognized the tan hamlet as a possible new species in their 1960 paper. The ending orum refers to "of man (men) and woman(women)". J. E. Randall collected the holotype (Ref. 88139).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 15; Anal spines: 3; Anal soft rays: 7; Vertebrae: 23 - 24. The tan hamlet is distinguished from its congeners by coloration. Its body is uniformly light brown to tan colored. It possesses distinct nose spots, a spot at the base of the pectoral fin and a caudal peduncle spot (Ref. 88139).

A 7.02 cm SL specimen of this species, collected 8 July 1990 on reefs off the Discovery Bay Marine Laboratory in Jamaica, had a freshly consumed a cleaner goby, Elacatinus evelynae (16.5 mm SL) in its stomach content (Ref. 88139).
