Etymology: Nannocharax: Latin, nannus = small + Greek, charax = a marine fish without identification (Ref. 45335); rubensteini: The species name, rubensteini, is in recognition of David Rubenstein who generously funded the Rubenstein Fellowships of the Encyclopedia of Life at the National Museum of Natural History (Ref. 93227).

Diagnosis: Hemigrammocharax rubensteini is distinguished from all congeners, except H. lineostriatus, by the presence of a dark, typically continuous, longitudinal band extending from the posterodorsal margin of the opercle to the dark spot overlying the caudal peduncle, vs. a body pigmentation pattern consisting of several vertical bars in H. angolensis, H. machadoi, H. minutus, H. monardi, H. multifasciatus, and H. wittei or lacking a dark longitudinal band in H. ocellicauda and H. uniocellatus (Ref. 93227). Hemigrammocharax rubensteini differs from H. lineostriatus in having the dorsal-fin origin located anterior to the vertical through the pelvic-fin origin, vs. the dorsal-fin origin located posterior to the vertical through the pelvic-fin insertion; 18 to 30 perforated scales along the lateral line, vs. 6 to 9; and 12 to 14 branched dorsal-fin rays, vs. 9 to 11 (Ref. 93227). Hemigrammocharax rubensteini has a variably discontinuous lateral line which in some instances has only a few unpored scales and thus approximates the completely pored lateral line characteristic of the species of Nannocharax; it differs also from the members of that genus with a continuous dark midlateral longitudinal band both in the incompletely pored lateral line, vs. completely pored; and the lower number of total scales along that series, 35-38 vs. 39 or greater in N. ansorgii, N. latifasciatus, N. lineomaculatus, N. parvus and N. usongo (Ref. 93227).
