Etymology: Stigmatochromis: Greek, stigma = mark, signal + Greek, chromis = a fish, perhaps a perch (Ref. 45335); macrorhynchos: Specific epithet a noun in apposition from Greek makros meaning 'long' and rhynchos meaning 'snout', referring to the elongated snout of this species (Ref. 87930).

簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 15 - 16; 背的軟條 (總數): 10-11; 臀棘 3; 臀鰭軟條: 8 - 9. Diagnosis: The presence of supra-pectoral and supra-anal spots, which do not extend to the base of the dorsal fin, combined with a snout length longer than the post-orbital head length distinguishes this species as a member of Stigmatochromis (Ref. 87930). It is further diagnosed by the presence of mostly unicuspid teeth in the outer rows of the lower jaws; Stigmatochromis macrorhynchos has a narrower interorbital width than S. melanchros, 13.7–16.2% of head length vs. 19.3–20.5%, and a shorter snout to pelvic-fin origin than S. melanchros and S. modestus, 38.4-40.3% of standard length vs. 42.2-44.6% and 42.2-46.9% respectively; the distance between the dorsal fin origin and the posterior anal fin insertion is shorter in S. macrorhynchos, 51.2–51.8% of standard length, than in all other Stigmatochromis species, 53.5–57.2%; the distance between the anterior dorsal fin to pelvic-fin origin of S. macrorhynchos, 27.7–30.0% of standard length, is shorter than in S. modestus, 30.3–33.8%, S. woodi, 31.9–38.1%, and S. melanchros, 35.7–36.1%, and longer than in S. pholidophorus, 26.8%, and S. pleurospilus, 27.5%; the snout length of S. macrorhynchos, 38.0–41.2% of head length, is longer than in S. modestus, 33.5–37.4%, and S. pholidophorus, 37.1%; the smaller head depth of S. macrorhynchos, 59.8–63.6% of head length, further distinguishes it from S. woodi, 64.1–75.8%, and S. melanchros, 67.8–76.8% (Ref. 87930).
