Etymology: Labeotropheus: Latin, labeo = one who has large lips + Greek, tropaion = defeat, a memorial of a fighting war, trophy; because of their specialized teeth were such an obvious feeding adaptation (Ref. 45335); artatorostris: The specific epithet is a composite of two Latin words, artatus, meaning constricted or shortened, and rostris, meaning nose or snout; this refers to the short snout pad that is characteristic of this species, especially in comparison to the type specimens of Labeotropheus fuelleborni (Ref. 116021).

Espinas dorsales (total) : 15 - 18; Radios blandos dorsales (total) : 8 - 9; Espinas anales: 3; Radios blandos anales: 6 - 8. Diagnosis: All diagnostic characteristics of Labeotropheus are present, including a steeply sloping head; broad, fleshy snout; wide jaws with retrognathous lower jaw; and an interior and subterminal mouth (Ref. 116021). Labeotropheus artatorostris differs from the slender-bodied Labeotropheus, L. trewavasae and L. simoneae, by its deeper body depth, 34.3-42.0% of standard length vs. 26.9-30.8% in L. simoneae and 25.3-33.4% in L. trewavasae; greater distance between insertion of dorsal fin and origin of anal fin, 29.2-34.0% of standard length vs. 27.4-28.6% in L. simoneae and 26.3-29.1% in L. trewavasae; and greater distance between origin of dorsal fin and insertion of pelvic fins, 36.1-41.1% of standard length vs. 27.5-32.8% in L. simoneae and 26.1-32.7% in L. trewavasae (Ref. 116021). Labeotropheus artatorostris is different from L. curvirostris by having more teeth rows in both the upper and lower jaws, 5-8 vs. 3 and 3-8 vs. 1, respectively; more infraorbital neuromasts, 12-36 vs. 9; shorter upper jaw, 15.6-22.9% of head length vs. 23.6%; and a narrower snout, 33.2-40.2% of head length vs. 42.6% (Ref. 116021). It differs from L. fuelleborni due to a shorter snout pad, 7.43-14.2% of head length vs. 14.9-17.2% in L. fuelleborni and 9.0-17.2% in types of L. fuelleborni and Messule specimens; more rows of teeth in the upper jaw, 5-8 vs. 4-5 in L. fuelleborni types and Messule specimens; and more gillrakers on the first ceratobranchial, 7-10 vs. 7-8 in L. fuelleborni (Ref. 116021). It differs from L. chlorosiglos due to greater distance between the opercular tabs, 16.6-18.7% of standard length vs. 14.7-15.7% in L. chlorosiglos; and greater distance between origin of dorsal fin and insertion of pelvic fin, 36.1-41.1% of standard length vs. 33.0-36.0% in L. chlorosiglos (Ref. 116021). Labeotropheus artatorostris also has longer pectoral fins, 24.6-33.3% of standard length, than all other species of Labeotropheus: 22.2-26.0% in L. chlorosiglos, 23.1-25.7% in L. fuelleborni, 22.2-29.3% in L. fuelleborni types and Messule specimens, 21.9-26.3% in L. simoneae, and 18.4-23.9% in L. trewavasae; it has also a wider body than all other species of Labeotropheus, body width at pectoral fins 14.0-18.3% of standard length vs. 12.7-14.3% in L. chlorosiglos, 15.0-16.9% in L. fuelleborni, 13.1-17.9% in L. fuelleborni types and Messule specimens, 13.0-15.6% in L. simoneae, and 12.1-16.6% in L. trewavasae; body width at opercular tabs 16.6-18.7% of standard length vs. 14.7-15.7% in L. chlorosiglos, 16.2-18.2% in L. fuelleborni, 15.3-18.4% in L. fuelleborni types and Messule specimens, 14.7-16.7% in L. simoneae, and 12.1-16.6% in L. trewavasae (Ref. 116021). Finally, L. artatorostris differs from all other species of Labeotropheus based on fin colouration of males: presence of orange-red pigmentation in pelvic, anal, and rayed dorsal fins in L. artatorostris vs. all fins blue in L. fuelleborni and L. trewavasae, and whitish-blue anal and yellow-rayed dorsal fins in L. chlorosiglos and L. simoneae; Labeotropheus artatorostris also lacks the large orange flank patch found in L. chlorosiglos and L. simoneae, and the orange pigmentation present on operculum of L. simoneae (Ref. 116021).
