Africa: Endemic to Lake Malawi. In 1988, a small population was found at Nkomo Reef, of which one specimen was positively identified. In 1989, a few specimens were seen at Makanjila Point, of which no individuals were caught for positive identification.
非洲: 馬拉威湖的特有種。 在 1988 年，一個小的族群被發現於 Nkomo 礁,其中一件標本肯定地被鑑定。 在 1989 年，一些標本在 Makanjila 點被見到,其中沒有個體被因為積極的鑑定而捕捉。

簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 16; 背的軟條 (總數): 11; 臀棘 3; 臀鰭軟條: 8. Differs from P. fenestratus and P. taeniolatus in the more specialized form of the jaws, with the dental arch of the premaxilla narrow anteriorly, but spreading laterally at the posterior ends, with rather long anterior teeth, and in the enlargement of the pharyngeal teeth.
有別於特殊化顎的形式的更多的 P. fenestratus 與 P. taeniolatus, 藉由前頜骨的牙齒弓狹窄的前面地, 但是在後端側面地傳佈, 有相當長的前面齒, 與在咽齒的增大方面。
Individuals at Nkomo Reef were observed to occur over sand and scattered rocks at a depth of about 17 m. Feeds from the rocks and small pebbles of the environment and also from the zooplankton when this is available (Ref. 5595).
Nkomo 礁的個體被觀察出現沙子之上與分散的岩石深度大約 17 公尺。 當這是有用的時候，從環境的岩石與小小圓石以及從浮游動物覓食。 (參考文獻 5595)
