背棘 (总数) : 28 - 35; 背的软条 (总数) : 82 - 101; 臀鳍软条: 79 - 100; 脊椎骨: 92 - 105. Diagnosis: 92-105 total vertebrae (median 99)[Konkouré River basin: 100-104 (median 102)]; 27+1 up to 34+1 (median 31+1) dorsal spines [Konkouré River basin: 29+1 up to 32+1 (median 31+1)]; no reduction of the pre-opercular spines with increasing length (Ref. 57415). No (exceptionally) up to 1 preorbital spine (Ref. 57415). 1 (very exceptionally) to 5 pre-opercular spines (median 2) (Ref. 55095, 57415). Origin of 1st dorsal spine situated posterior to posterior edge of pectoral fin, 4.8-47.4% HL (m=24.8); distance from anterior border of snout to last externally visible dorsal spine 52.6-61.5% SL (m=57.2), comparable to distance from anterior border of snout to last externally visible anal spine, 53.1-61.9% SL (m=57.8), both decreasing with size; post-anal length 42.3-50.9% SL (m=45.9) and increasing with size, shorter than pre-anal length, 48.5-56.8% SL (m=52.6) and decreasing with size, becoming equal to latter with increasing size; 6-12 caudal fin rays; 7-11 predorsal vertebrae; 37-42 abdominal vertebrae; 0-(+2) in-between vertebrae; 53-64 caudal vertebrae (Ref. 57415).
Mastacembelus liberiensis 有一个钝的吻。 (参考文献 55095) 唇的后面的角被位于从大约在后面的 nare 的水平中央之下在眼的前缘之下向上到.(参考文献 55095) 鳃裂的上面角落些微地位于前, 或在下面, 胸鳍基底的背部点, 两者的点清楚地位于胸鳍基底的腹点前; 位于主要地高于鳃裂的上面角落的胸鳍基底的背部点.(参考文献 55095) 鳃裂关闭为大约一半或者整个的垂直背部与胸鳍基底的腹面边缘之间的距离.(参考文献 55095) 侧线是黄白色而且在較前端中可能是連續的從頭部向上到一胸鰭長度超過胸鰭的後緣; 側線的剩餘又較向後部份總是清楚不連續。 (參考文獻 55095) 肛門前部分的長度否定地 allometric, 肛門後的長度肯定地 allometris.(參考文獻 55095) 一個相當高的背棘數目, 從第一支到最後一支的在大小方面的有硬棘增加; 在皮膚下面藏的一根附加的非常短的棘而且位於第一背鰭鰭條的基底前面了.(參考文獻 55095) 二個外部看得見的臀鰭硬棘, 比第二個小的第一個; 一根附加的非常短的棘, 在皮膚下面藏, 而且位於第一個臀鰭鰭條的基底前面了.(參考文獻 55095) 前鰓蓋骨棘數字各種各樣的從 1L/1R 向上到 5L/5R.(參考文獻 55095)
Maximum TL observed was 383mm (Ref. 57415).
