It also differs from X. myersi by having the caudal fin lanceolate in males, with a pronounced posterior tip (vs. sub-lanceolate, never forming a distinctive tip posteriorly), more dark grey bars on the flank in females (12-13 vs. 9-11), a more slender body (body depth 27.1-28.5% SL in males and 28.5-30.6% in females, vs. 29.0-31.4% and 30.1-33.9%), and a shorter lower jaw (18.6-20.9% of head length in males and 17.7-19.7% in females, vs. 22.4-24.5% and 19.6-21.4%, respectively); from X. pataxo by the possession of two or three black spots on the posterior part of the caudal peduncle in females (vs. absence); and from X. cricarensis by having a more slender head in males (head depth 81.2-85.0% of head length vs. 85.6-92.8%), a shorter lower jaw in males (18.6-20.9% of head length vs. 22.0-25.0%) and a more slender body in larger males (above 31 mm SL) (body depth 27.1-27.5% SL, vs. 30.7-33.9% SL) (Ref. 96072).Description: Dorsal fin with 16-18 rays in males, 13-15 rays in females; anal fin with 21-23 rays in males, 19-21 rays in females; extremity of dorsal fin pointed and long in males, rounded to slightly pointed in females; tip of anal fin pointed in males, rounded in females; caudal fin lanceolate with pointed extension often bearing two short filamentous rays (Ref. 96072).
