脊椎骨: 35. Pelvic fins united medially for their entire length, except for a small notch distally. Pelvic fins widely separated to base in all other Pseudecheneis. Outer ray of pelvic fin with unculi in lamellae on both dorsal and ventral surfaces. Transverse lamellae in thoracic adhesive disc 14 (versus 9-12 in P. paviei, 8-13 in P. intermedius, 13-20 in P. sulcatoides, 14-20 in P. sulcatus, 14-21 in P. immaculatus, and 20 or 21 in P. tchangi). Vertebrae in caudal peduncle (entirely posterior to anal fin base) 10.
腹鳍中间地纵贯全身长度联合了, 末梢部地除了一个小的凹槽。 腹鳍对在所有的其他 Pseudecheneis 中的基底分得很开。 在两者的背面与腹面上的嗅板中的腹鳍有 unculi 的外部鳍条。 在胸廓的黏盘 14 中的横跨嗅板.(对 9-12 在 P. paviei,8-13 在 P. intermedius,13-20 在 P. sulcatoides,14-20 在 P. sulcatus,14-21 在 P. immaculatus, 与 20 或 21 在 P. tchangi) 在尾柄 (完全地在臀鳍基底后面)10 中的脊椎骨.
