Etymology: Maylandia: In honour of Hans J. Mayland, German ictiologist (Ref. 45335); flavicauda: The name flavicauda is a noun in apposition and derives from the Latin flavus meaning 'yellow' and cauda meaining 'tail', and refers to the yellow tail of territorial males (Ref. 119465).
Eponymy: Hans-Joachim Mayland (1928–2004) was a German ichthyologist, aquarist, photographer and writer. [...] (Ref. 128868), visit book page.

背棘 (總數) : 17 - 19; 背的軟條 (總數) : 8 - 10; 臀棘: 2 - 3; 臀鰭軟條: 8 - 9. Diagnosis: The presence of bicuspid teeth in the outer rows on both the upper and lower jaws and a moderately sloped vomer with a swollen rostral tip place this species in Maylandia (Ref. 119465). Male and female M. flavicauda are distinguished by an elongate body, body depth 23.6-28.5% of standard length, from all other species in Maylandia, body depth 28.8-40.8% of standard length, except M. tarakiki, body depth 25.8-32.9% of standard length, and M. usisyae, body depth 25.9-30.6% of standard length (Ref. 119465). It is distinguished from M. usisyae by a deeper preorbital bone, preorbital depth 18.0-26.9% of head length, and a longer snout, snout length 34.3-47.3% of head length, which are 17.6-21.2% and 32.0-37.6% in head length in M. usisyae respectively; based on the colour pattern, males of M. flavicauda possess 5-6 black lateral bars, black pelvic fins, a black anal fin, a yellow caudal fin, and a black dorsal fin with yellow/orange spots distally; males of M. usisyae have a yellow dorsal fin with a black submarginal band, a yellow pelvic fin and a yellow anal fin with a black leading edge; males of M. tarakikihave 7-9 lateral bars, and gray-blue/dark gray caudal fin (Ref. 119465). Females of M. flavicauda can be distinguished from those of M. tarakiki by a bluish/brown ground colouration without lateral bars; in female M. tarakiki, the ground colour is light brown with blue center-flank scales and dark brown lateral bars; based on colouration alone, females of M. flavicauda cannot reliably be distinguished from those of M. usisyae (Ref. 119465). Maylandia flavicauda also possess a relatively smaller eye than M. tarakiki, horizontal eye diameter 20.5-30.6% of head length vs. 27.2-36.3% in M. tarakiki (Ref. 119465).
