Etymology: Mylochromis: Greek, mylo = mill + Greek, chromis = a fish without identification, perhaps a perch (Ref. 45335); ensatus: Specific epithet is the Latin adjective ensatus, meaning shaped like a two-edged sword and refers to the characteristic shallow, straight, elongate body form and the acutely pointed head of this species (Ref. 41276).
Environment: milieu / climate zone / depth range / distribution range

背棘 (總數) : 16 - 17; 背的軟條 (總數) : 13 - 14; 臀棘: 3; 臀鰭軟條: 10 - 11.
能從 Mylochromis 的種被區別, 除了 M. gracilis 以外與 M. spilostichus 藉著具有較淺的身體;(26-28% SL vs.29-44) 而且較多的側線鱗片.(37-38 vs.30-36) 在 M. spilostichus 中的時候, 斜紋是連續的, 延伸到尾梗, 條紋被夾雜著一系列的斑點而且在 M. gracilis 中，條紋可能是斷掉而不會延伸到尾梗。 M. spilostichus 與 M. gracilis 通常超過 M. ensatus 持有一個非常水淺的眶前骨深度 (16.7 與 19.2-20.0, vs.19.9-26) 。 (參考文獻 41276)
Inhabits shallow sandy shores; rare species (Ref. 41276). Feeds on invertebrates found in the sand (Ref. 79521).
