簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 11; 臀鰭軟條: 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 是在四個種中最小的; 尾梗長度是最長的,在雌性中的雄性與 21.3-27.0% SL 中作為 23.8-24.6% SL; 雄性成魚的臀鰭棘條不是在一個箭頭形的斷面擴大; 雄性成魚的臀鰭棘條的片段不是融合的; 雄性的臀鰭棘條的鱗質鰭條的近側端的前面延長不存在。
