中文摘要 | 本文報告馬來半島東南部之Endau河川集水區之魚種名錄。名錄中共報導Endau當地中26科108種魚類。其中36種為新記錄,2種為新種。其中小眼粒鯰(Akysis microps)為粒鯰科之一新種。本種與異尾粒鯰(A. heterurus)相近,但與此種及與同屬他種之差異在下列特徵之綜合:尾高為標準體長之8.3%∼9.6%,臀鰭基長為標準體長之16.2%∼18.6,脂鰭基長為標準體長之15.2%∼23%,眼徑為頭長之9%∼13%,鼻鬚長為頭長之95%∼106%,頷鬚長為頭長之139%∼170%,內顎鬚長為頭長之94%∼102%,外顎鬚長為頭長之110%∼154%:臀鰭鰭條10∼11,胸鰭棘後緣有5∼7鋸齒。星雲短鱨(Nanobagrus nebulosus)為鮠科之一新種,其特徵為眼大(眼徑為頭長之14.1%∼15.1%),胸鰭後緣有16個鋸齒,脊椎骨35∼36個,其暗灰色體軀上有一系列乳酪色斑,大多在體之背面。本種亦為馬來半島本科之新記錄屬。 |
英文摘要 | An annotated checklist of the fishes of the Endau River drainage in southeastern Peninsular Malaysia is provided. A total of 108 species in 26 families is reported from the Endau basin, of which 36 are new records and 2 are new species of catfish described here. Akysis microps, new species (Akysidae) resembles A. heterurus, but differs from it and other congeners by the following unique combination of characters: depth of caudal peduncle 8.3%-9.6% SL, length of anal-fin base 16.2%-18.6% SL, length of adipose-fin base 15.2%-23.0% SL, eye diameter 9%-13% HL, length of nasal barbel 95%-106% HL, length of maxillary barbel 139%-170% HL, length of inner mandibular barbel 94-102% HL, length of outer mandibular barbel 110%-154% HL, 10-11 anal-fin rays, and 5-7 serrations on the posterior edge of the pectoral spine. Nanobagrus nebulosus, new species (Bagridae), is characterized by large eyes (eye diameter 14.1%-15.1% HL), pectoral spine with 16 serrations on the posterior edge, 35-36 vertebrae, and a dark grayish-brown body with a series of cream-colored spots mostly on the dorsal surface of the body. It is also the 1st record of the genus from Peninsular Malaysia. |
