ABSTRACT

We describe the larval morphology of the stream-dwelling tadpole of Hyloscirtus antioquia based on specimens from the type locality, Antioquia, Colombia. The larvae of H. antioquia (belong to the suctorial ecomorphological guild) show morphological characters commonly associated with lotic habitats, like a depressed body, low fins, long tail, well-developed tail musculature, and oral disc with many labial tooth rows. In addition, the larvae of H. antioquia have the anterior and posterior jaw sheath with small serrations and the inner margin of nostrils with one simple triangular fleshy projection. As in other cases in Hyloscirtus, the tadpole H. antioquia has a large saccular structure that encloses the vent tube, and partially covers the hindlimbs during their development, and also it has the ventrolateral, unpigmented spots in the region proximal to the vent tube. Finally, some aspects concerning the larvae of the tribe Cophomantini are discussed.

摘要

我们根据来自哥伦比亚安蒂奥基亚的典型地区的标本描述了生活在溪流中的Hyloscirtus antioquia蝌蚪的幼虫形态。H. antioquia的幼虫（属于吸食生态形态学协会）表现出通常与激流栖息地相关的形态特征，如身体凹陷、鳍低、尾长、尾肌肉发达、口腔盘有许多唇齿列。此外，H. antioquia幼虫的前后颚鞘有小锯齿，鼻孔内缘有一个简单的三角形肉质突起。与Hyloscirtus 的其他情况一样，蝌蚪H. antioquia具有包围排气管的大囊状结构，并在其发育过程中部分覆盖后肢，并且在靠近排气管的区域具有腹外侧、未着色的斑点。最后，讨论了有关 Cophomantini 部落幼虫的一些方面。
