背的軟條 (總數) : 3; 臀鰭軟條: 3. Diagnosis: Metamorphosed females of Acentrophryne longidens differ from A. dolichonema in having a much shorter distal escal appendage (2.3-2.5% SL vs. 27.6-35.7% SL); a shorter illicium (35.7-54.9% SL vs. 63.6-70.5% SL); a wider head (35.7-37.3% SL vs. 25-28.1% SL); and a greater number of pectoral fin rays (18-19 vs. 16) (Ref. 54827); caudal fin rays 9, ninth ray (ventral most) 18.6-22.6% SL (Ref. 86949).
Body shape (shape guide): short and / or deep; Cross section: oval.
鑑別: 長牙無刺鮟鱇〔Acentrophryne longidens〕 的變態雌性在有一個方面不同於 A. dolichonema 非常短的末梢部的餌球附肢 (2.3-2.5% SL 和 27.6-35.7% SL 比較); 一個較短的誘餌 (35.7-54.9% SL 和 63.6-70.5% SL 比較); 一個較寬的頭部 (35.7-37.3% SL 和 25-28.1% SL 比較); 而且一個較多的胸鰭鰭條 (18-19 vs.16).(參考文獻 54827)
