Abstract

A new viviparous halfbeak, Nomorhamphus aenigma, new species, from the upper stream of the Cerekang River in central Sulawesi, Indonesia is described. The new species is distinguished from all other zenarchopterids by the complete absence of elongate lower jaws. Although secondary loss of elongate jaws is also known from several hemiramphids, N. aenigma, new species, is clearly different from them by having no elongate jaws throughout ontogeny.

苏拉威西岛Nomorhamphus属一种新的“无喙”半喙鸟（Teleosterie:Zenarchopteriae）

本文报道了印度尼西亚苏拉威西岛中部Cerekang河上游的一种新的胎生半喙动物Nomorhamphus aenigma。这个新物种与所有其他天顶翼类的区别在于完全没有细长的下颚。虽然几种半隐足类也已知细长颚的二次缺失，但新物种N.aenigma与它们明显不同，因为在整个个体发育过程中没有细长颚。
