背的软条 (总数) : 11; 臀鳍软条: 12 - 13; 脊椎骨: 35 - 36. The eyes of S. papilliferus (18.4-26.0% HL) are the smallest of the four species of Spintherobolus; the caudal peduncle length is the longest, being 23.8-24.6% SL in males and 21.3-27.0% SL in females; the anal-fin rays of adult males are not expanded in a sagittal plane; segments of anal-fin rays of adult males are not fused; an anterior extension of the proximal end of the lepidotrichia of the anal-fin rays of males is absent.
S. papilliferus(18.4-26.0% HL) 的眼 Spintherobolus 是在四个种中最小的; 尾梗长度是最长的,在雌性中的雄性与 21.3-27.0% SL 中作为 23.8-24.6% SL; 雄性成鱼的臀鳍棘条不是在一个箭头形的断面扩大; 雄性成鱼的臀鳍棘条的片段不是融合的; 雄性的臀鳍棘条的鳞质鳍条的近侧端的前面延长不存在。

50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
