🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 17 - 19; Dorsal soft rays (total): 8 - 10; Anal spines: 3; Anal soft rays: 7 - 9. Diagnosis: The presence of bicuspid teeth in the anterior portion of the outer row on both the upper and lower jaws and a moderately sloped ethmo-vomerine block with a swollen rostral tip place this species in Maylandia . The presence of a black submarginal band in the dorsal fin in combination with distinct black lateral bars on a blue and/or yellow flank and with yellow pigment on the cheek and breast distinguish males of this species from those of all other members of the genus except from those of the Maleri Island population of M. flavifemina; Maylandia nigrodorsalis can be distinguished from M. flavifemina by a deeper cheek, being 25,3-32,0% of body depth in M. nigrodorsalis vs. 20,3-24,8% in M. flavifemina from Maleri Island . Female Maylandia nigrodorsalis are distinguished from all other female Maylandia, except from those of M. lundoense, by the presence of a black submarginal band in the dorsal fin; female M. nigrodorsalis cannot reliably be distinguished from those of M. lundoense . : fusiform / normal; Cross section: oval.
