背的軟條 (總數) : 10 - 11; 臀鰭軟條: 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; 臀鰭鰭條 (13-16) 的相當高計數與腹的前流尾鰭鰭條為相對於所有的其他種的 Spintherobolus 出現 autapomorphic 對於這個魚種的 S. broccae 計算 (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.
棲息於深褐色的沼澤水域。 似乎發現於在相當低地的區域中的略微酸的水域,在沼澤與緩慢移動的溪流中, 但是只在溪流保持不污染的區域中。
