Etymology: Hypoplectrus: Greek, hypo = under + Greek, plektron = sting, spur (Ref. 45335); randallorum: 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).

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).
