概要 | The panorpodid scorpionfly Panorpodes paradoxus, which inhabits mountainous regions, is known to display a variety of morphological polymorphisms. In particular, the short wing typed individuals only occurred in higher altitude regions of Northern and Central Japan, and they also exhibit many morphological differences to the long-winged types. Several researchers suggest that this short-winged type must be a distinct species to Panorpodes paradoxus. So, we conducted a molecular phylogenetic analysis in order to investigate how these various characteristics were obtained. Our results indicated that these two wing types could not be differentiated genetically. Furthermore, these various polymorphic characteristics are shown that have polyphyletic origins. That is, the short-winged type was polyphyleticly differentiable, and their various characteristics may be treated as a case of intra-specific “ecomorph” for adaptation to coldness, strong wind and ultraviolet radiation. |
