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); simoneae: This species is named in honour of Simone Josephine Pauers, daughter of author Michael J. Pauers, whose rosy cheeks reminds him of the bright orange opercula of the males of this species (Ref. 111073).

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 17 - 19; Raggi dorsali molli (totale) : 8 - 9; Spine anali: 3; Raggi anali molli: 7 - 8. Diagnosis: All diagnostic characteristics of Labeotropheus present: steeply sloping head; broad, fleshy snout; wide jaws with retrognathous lower jaw; mouth is inferior and subterminal (Ref. 111073). Labeotropheus simoneae differs from all other species of Labeotropheus in having extensive orange colouration on the operculum in males, vs. blue in L. fuelleborni, L. trewavasae and L. chlorosiglos; although the male nuptial colour pattern is extremely similar to that of L. chlorosiglos, the presence of the orange pigmentation on the operculum is a clear difference between L. simoneae and L. chlorosiglos (Ref. 111073). It differs from the deeper-bodied Labeotropheus primarily based on a shallow, slender body, body depth 28.4-30.8% of standard length vs. 35.1-41.6% in L. fuelleborni and 31.9-34.7% in L. chlorosiglos, and head, head depth 88.0-98.8% of head length vs. 101.2-108.9% in L. fuelleborni and 99.3-108.0% in L. chlorosiglos, as well as a shorter distance from the origin of the dorsal fin to the origin of the anal fin, 47.1-50.5% of standard length in L. simoneae vs. 51.3-54.6% in L. chlorosiglos and 52.5-55.5% in L. fuelleborni, and a shorter distance between insertion of the dorsal fin and the origin of the anal fin, 27.4-28.5% of standard length in L. simoneae vs. 29.1-33.2% in L. chlorosiglos and 29.6-31.7% in L. fuelleborni (Ref. 111073). It differs from L. trewavasae in the number of neuromasts present in the infraorbital pores, 27-29 vs. 8-25 in L. trewavasae, and has generally larger pectoral fins, 21.9-26.3% of standard length vs. 20.8-23.9% in L. trewavasae, greater distance between the insertion of the dorsal fin and the insertion of the anal fin, 14.6-16.0% of standard length vs. 12.7-15.5% in L. trewavasae, deeper preorbital depth, 24.0-28.5% of head length vs. 21.2-27.6% in L. trewavasae, longer and wider lower jaw, 27.4-36.3% of head length vs. 23.0-32.7% and 41.2-47.8% of head length vs. 34.7-43.9% respectively, and a greater interorbital width, 34.6-42.7% of head length vs. 29.6-40.5% (Ref. 111073).
