背棘 (总数) : 0; 臀棘: 0; 脊椎骨: 35 - 37. 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).
Body shape (shape guide): elongated; Cross section: compressed.
