背的软条 (总数) : 3; 臀鳍软条: 3. Diagnosis: Metamorphosed females of Acentrophryne dolichonema differs from A. longidens in having a much longer distal escal appendage (27.6-35.7% SL vs. 2.3-2.5% SL ); a longer illicium (63.6-70.5% SL vs. 35.7-54.9% SL); a narrower head (25-28.1% SL vs. 35.7-37.3% SL); and a fewer number of pectoral fin rays (16 vs. 18-19) (Ref. 54827); caudal fin rays 9, ninth ray (ventral most) 10.5-17.3% SL (Ref. 86949).
鉴别: Acentrophryne dolichonema 的变态雌性在有一个方面有别于 A. longidens 更长末梢部的饵球附肢 (27.6-35.7% SL 和 2.3-2.5% SL 比较 ); 一个较长的诱饵 (63.6-70.5% SL 和 35.7-54.9% SL 比较); 一个较狭窄的头部 (25-28.1% SL 和 35.7-37.3% SL 比较); 而且一个胸鳍鳍条 (16 vs.18-19) 的较少的数字.(参考文献 54827)
