簡短描述
檢索表 | 型態特徵 | 形態測量圖
Differs from all other Chaetostoma by the combination of the following characters: presence of a dermal keel on the posterior tip of the supraoccipital; reduced number of invertible odontodes (2-5) in the interopercular region; and the presence of three smooth, large, digitiform papillate projections in the buccal cavity (Ref. 26719).
有別於所有的其他 Chaetostoma 藉由下列特徵的組合: 在上枕骨的後面的頂端上有一個表皮的龍骨脊; 在間鰓蓋骨區域中的倒轉齒 (2-5) 的少的數量; 而且那有三平滑的﹐大的, digitiform 在噴水孔中的有乳頭狀突起的突出.(參考文獻 26719)
