簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 38. Pseudecheneis maurus is distinguished from all congeners in having a shorter adipose-fin base (1.2 times length of anal-fin base vs. 1.5–2.0 times; 15.7% SL vs. 17.6–30.6), (except for P. sympelvica) thoracic adhesive apparatus with sulcae not meeting (vs. meeting) at midline and (except for P. immaculata) in lacking (vs. having) distinct pale spots on the body It further differs from P. immaculata in having a shorter pectoral fin (24.3% SL vs. 32.0) and shorter and deeper caudal peduncle (length 21.2% SL vs. 28.8; depth 6.0% SL vs. 4.0). from. It differs from P. paviei and P. sympelvica in having an elongate body with 38 vertebrae (vs. short body with 33–35 vertebrae) and from P. sympelvica in having separate (vs. fused) pelvic fins. Barbels flattened, and in four pairs. Maxillary barbel with ventral surface densely covered with papillae, and pointed tip; barbel extending about two-thirds of distance between its base and base of first pectoral-fin element. Distal half of barbel attached to snout via large, thin flap of skin. Nasal barbel with small flap of thin skin fringing posterior margin and extending midway to distance between posterior nares and anterior orbital margin. Inner mandibular-barbel densely covered with papillae; origin close to midline, extending to collar on distal margin of branchiostegal membrane. Outer mandibular barbel originating posterolateral of inner mandibular barbel, extending to level of anterior orbital margin. Eye small and almost rounded, subcutaneous and located on dorsal surface of head.Thoracic adhesive apparatus consisting of 13 transverse ridges (laminae) separated by grooves (sulcae); sulcae not meeting at midline of adhesive apparatus. Adhesive apparatus extending from immediately posterior to collar on distal margin of branchiostegal membrane to immediately posterior to level of last pectoralfin ray (Ref. 57940).
Pseudecheneis maurus 在有一個方面被與所有的同類區分較短的脂鰭
基底 (1.2 倍臀鰭基底的長度 vs.1.5-2.0 倍; 15.7% SL vs.17.6-30.6), (除了 P. sympelvica) 胸廓的黏著器官用 sulcae 不碰到 (vs. 碰到) 在中線與 (除了 P. immaculata) 在身體上的缺乏 (vs. 有) 明顯的灰白斑點中，它進一步有別於 P. immaculata 在有一個方面較短的胸鰭 (24.3% SL vs.32.0) 與更短與更深的尾柄 (長度 21.2% SL vs.28.8; 深度 6.0% SL vs.4.0). 從。 它有別於 P. paviei 與 P. sympelvica 在用 38個脊椎骨 (vs. 短的身體有 33-35個脊椎骨) 與從 P. sympelvica 有一個細長的身體方面有分開 (vs. 融合) 腹鰭。 觸鬚平的, 與在四對中。 上頜骨觸鬚用腹面濃密地覆蓋著乳突 , 與尖的頂端了; 觸鬚延伸大約三分之二它的基底與第一個胸鰭要素的基底之間的距離。 末梢部一半的觸鬚經由大又細的皮蓋依附於吻了。 鼻骨觸鬚有小的被邊緣後緣而且延伸中途在後部的鼻孔與前面的眼窩邊緣之間的距離的薄皮的鰓蓋。 內部的顎骨-觸鬚濃密地覆蓋著乳突了; 起源接近被在鰓蓋薄膜的末梢部邊緣上延伸至頸圈的中線。 外部的顎觸鬚開始後側的被延伸至前面眼窩的邊緣的水平的內部顎的觸鬚。 眼小與幾乎圓形, 皮下的而且位於頭部背面上了。包含 13個橫跨的脊 (葉片) 的胸廓黏著器官藉著凹槽 (sulcae) 分開; sulcae 在黏著器官的中線不碰到。 黏著器官延伸從緊鄰在鰓蓋薄膜的末梢部邊緣之上的頸圈後面緊鄰在最後 pectoralfin 鰭條的水平後面.(參考文獻 57940)
