背的软条 (总数) : 10 - 11; 臀鳍软条: 16 - 20; 脊椎骨: 32 - 34. Lacks infraorbital bone3; the relatively high counts of anal-fin ray (13-16) and ventral procurrent caudal fin ray count (14-17) for S. broccae relative to all other species of Spintherobolus appears autapomorphic for this species.
缺乏眶下的硬骨 3; 臀鳍鳍条 (13-16) 的相当高计数与腹的前流尾鳍鳍条为相对于所有的其他种的 Spintherobolus 出现 autapomorphic 对于这个鱼种的 S. broccae 计算 (14-17) 。
Inhabits dark-brown swamp waters. Appears to be found in somewhat acid waters in relatively lowland areas, in both swamps and slow moving streams, but only in areas where the streams remain unpolluted.

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): 3.0 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
