Larval characters play a significant role in evolutionary and systematic studies of holometabolous insects. However, Panorpodidae, a derived family of Mecoptera, are largely unknown in their immature stages to date. Here, the first instar larva of the short-faced scorpionfly Panorpodes kuandianensis Zhong, Zhang & Hua, 2011 is described and illustrated using light and scanning electron microscopy. The larva of Panorpodes is remarkable for the absence of compound eyes on the head and the presence of seven small unpaired proleg-like processes along the midventral line on abdominal segments II-VIII. The homology of these unpaired appendage-like processes, their ecological adaptation, and the evolutionary implications of some larval characters of Panorpodidae are discussed.
幼虫特征在全变态昆虫的进化和系统发育研究中起着重要作用。然而，蝎蛉科作为长翅目一个衍生的科，其未成熟阶段迄今在很大程度上仍不为人知。在此，利用光学显微镜和扫描电子显微镜对2011年钟、张和华发现的短面蝎蛉宽甸蝎蛉的一龄幼虫进行了描述和图示。宽甸蝎蛉幼虫的显著特征是头部没有复眼，并且在腹部第二至八节的腹中线有七个小的不成对的类似腹足的突起。本文讨论了这些不成对的附肢状突起的同源性、它们的生态适应性以及蝎蛉科一些幼虫特征的进化意义。
