Furthermore, Curculionichthys tukana can be separated from C. insperatus and C. oliveirai by lacking large conspicuous odontodes forming rows on head and trunk (vs. large, conspicuous odontodes forming rows on the head present); from C. oliveirai and C. coxipone by having the anterior profile of the head pointed (vs. anterior profile of head rounded); from C. paresi by having 12-18 premaxillary teeth (vs. 6-10) and 10-16 dentary teeth (vs. 4-7); from C. sabaji by the absence of dark-brown spots scattered over the body (vs. the presence of dark-brown spots); from C. paresi by absence of contrasting dark spots at the anterodorsal region of body (vs. the presence of such pigmentation pattern). In addition, Curculionichthys tukana can be differentiated from C. piracanjuba by having odontodes forming aligned rows, more evident in the dorsal portion of head and in the lateral portion of caudal peduncle (vs. odontodes not forming rows on the supraoccipital, on the compound pterotic, and on the lateral plates series) (Ref. 118146).Description: Dorsal-fin rays ii,7; anal-fin rays i,5; pectoral-fin rays i,6; pelvic-fin rays i,5 (Ref. 118146).
