Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Cichlidae (Cichlids) > Pseudocrenilabrinae
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);  chlorosiglos: The specific epithet is a composite of two Greek words, chloros, meaning green, and siglos, meaning earrings; this refers to the metallic green opercular tabs present on both males and females (Ref. 111073).

Short description Morphology | Morphometrics

Dorsal spines (total): 17 - 19; Dorsal soft rays (total): 8-9; Anal spines: 3; Anal soft rays: 7 - 8. Diagnosis: All diagnostic characteristics of Labeotropheus present: steely sloping head; broad, fleshy snout; wide jaws with retrognathous lower jaw; mouth is inferior and subterminal (Ref. 111073). Labeotropheus chlorosiglos differs from L. fuelleborni and L. trewavasae by its intermediate body depth, 31.9-34.7% of standard length vs. 35.1-41.6% in L. fuelleborni and 26.3-33.3% in L. trewavasae; and its generally wider interorbital width, 40.6-43.5% of head length vs. 36.0-42.8% in L. fuelleborni and 29.6-40.5% in L. trewavasae; it further differs from both L. fuelleborni and L. trewavasae due to its intermediate lower jaw length, 42.1-47.6% of head length vs. 45.3-53.8% in L. fuelleborni and 34.7-43.9% in L. trewavasae; and male nuptial colour pattern, presence of yellow-orange patch on ventral portion of flank in L. chlorosiglos vs. solid blue body and fins in L. fuelleborni and solid blue body and fins or blue body and fins covered in small, irregular black spots in L. trewavasae (Ref. 111073). It differs from L. trewavasae by the following combination of characteristics: greater distance between the origin of the dorsal fin and the origin of the anal fin, 51.3-54.6% of standard length vs. 46.7-51.6% in L. trewavasae; greater distance between the insertion of the dorsal fin and the origin of the anal fin, 29.1-33.2% of standard length vs. 26.2-29.1% in L. trewavasae; and a deeper head, 40.6-43.5% of head length vs. 29.6-40.5% in L. trewavasae; it may also differ from L. trewavasae in the colour of the opercular tab, metallic green in L. chlorosiglos while it appears to be a metallic blue in L. trewavasae (Ref. 111073). It differs from L. fuelleborni due to its smaller opercular tab width, 14.7-15.7% of head length vs. 16.2-18.2%; smaller pectoral width, 12.7-14.3% of head length vs. 15.0-16.9%; greater number of ceratobranchial gill rakers, 8-10 vs. 7-8; and fewer number of scale rows between the pectoral and pelvic fins, 6-9 vs. 9-12; also, individuals of L. chlorosiglos always have more scale rows between the dorsal fin and lateral line, 8-10, than scale rows between the pectoral and pelvic fins, 6-9, while individuals of L. fuelleborni always have more scale rows between the pectoral and pelvic fins, 9-12, than scale rows between the dorsal fin and lateral line, 9-10 (Ref. 111073).
