; 淡水 底中水層性; 深度上下限 2 - 10 m (Ref. 26731). 熱帶
Africa: restricted to Chinyankwazi and Chinyamwezi Islands in the southeast arm of Lake Malawi. No specimens were observed elsewhere during the numerous diving expeditions throughout the southeast arm over the past 10 years.
非洲: 在東南馬拉威湖的手臂中侷限於 Chinyankwazi 與 Chinyamwezi 島了。 沒有標本在過去 10 年以來被在東南各處在很多的潛水遠征的時候觀察其他地方手臂。
