簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 16; 背的軟條 (總數) : 10 - 11; 臀棘: 3; 臀鰭軟條: 9 - 10. Small with small mouth, resembles P. pleurotaenia in body form and coloration. Different from other members of genus because of the greatly enlarged molariform, pharyngeal teeth and from P. pleurotaenia in the larger eye, longer premaxillary pedicel and broader head and body.
小且有小的嘴, 在體型與顏色中與 P. pleurotaenia 相似。 屬的不同與其他成員由於那明顯增大臼齒型, 咽齒與從 P. pleurotaenia 在比較大的眼, 比較長的上頜骨前的莖與較寬的頭部與身體中。
One of the two specimens collected was from an extensive shallow sandy area with Vallisneria beds. Stomach content consisted of a gastropod and a ceratopogonid larva (Ref. 267).
收集的二個中的一個標本以 苦草 床來自一個廣泛的水淺沙地區域。 腹部內容有了腹足動物與一個 ceratopogonid 幼體。 (參考文獻 267)
