簡短描述
檢索表 | 型態特徵 | 形態測量圖
Trichomycterus santanderensis can be distinguished from other species of the genus by the following combination of characters: variable reduction in eyes from visible to imperceptible
due to covering by a thick integument; relatively high head (62.5% of HL); enlarged mouth width (49% of HL); extended maxillary, nasal and rictal barbels (113.6%, 106.7% and 75% of HL, respectively); first pectoral ray extending as long filament, about 95% of pectoral-fin length; depth of the caudal peduncle 17.5% SL; caudal fin truncate with a slightly convex edge, upper portion of fin longer than lower portion; color varied from homogeneous light-red pigmentation of adults to pale rose with small grayish round spots on dorsum of young individuals (Ref. 58751).
Trichomycterus santanderensis 能在組合特徵之後被與其他種的本屬區分藉由: 看得見的在眼睛到中的可變減少到不能感知的
由於一個厚體表的覆蓋; 相當高的頭部 (62.5% 的 HL); 增大的嘴寬度 (49% 的 HL); 擴大的上頜骨，鼻骨與 rictal 觸鬚;(113.6%, 106.7% 與 75% 的 HL, 分別地) 第一個胸鰭鰭條延伸成長的絲狀突起，大約 95% 的胸鰭長度; 尾梗 17.5% SL 的深度; 尾鰭截形有一個些微中凸的邊緣, 鰭長度超過低的部分上面部分; 從成魚的同種淡紅色顏色到灰白的玫瑰被改變的顏色在幼魚的背面上有小的淺灰色的圓斑點。 (參考文獻 58751)
