背的软条 (总数) : 10 - 11; 臀鳍软条: 7 - 8. Black semicircular mark on each caudal lobe (Ref. 43281). Can be distinguished from its congeners by having a small scaleless midventral region only restricted to chest. Differs from P. robustus in having slightly crenulated rostral fold with 12-15 indentations on its distal margin, a shallower caudal peduncle (depth 63.7-71.3% of its length) and a larger mental adhesive disc (length 72.7-80.7% of its width) (Ref. 49783). Also Ref. 75600.
在每个尾叶上的黑色的半圆标志.(参考文献 43281) 能被藉由有一个与它的同类区分小的无鳞片的腹部中央的区域只局限于胸了。 有别于 P. robustus 用 12- 有些微细齿状嘴的折层 15个压痕在它的末梢部的边缘, 一个比较水浅的尾柄 (深度 63.7-71.3% 的它长度) 与一个比较大的神经黏盘 (长度 72.7-80.7% 的它宽度).(参考文献 49783)
