摘要

Alena属Navás, 1916,被认为是Raphidiidae中最独特的属,因为它的雄性生殖器硬骨的形状不寻常,而且它的地理分布仅限于美国西南部和墨西哥西部。本文报道了Aztekoraphidia U. Aspöck和H. Aspöck亚属的一新种- Alena (Aztekoraphidia) alanaesp。11 .基于这一发现,我们进行了详细的形态研究和Alena的第一次形态系统发育。我们的结果恢复该属为单系,包括Aztekoraphidia亚属,它是由另外两个单系亚属Alenas.s组成的分支的姊妹。Navás, 1916年,以及Mexicoraphidia U. Aspöck和H. Aspöck, 1970年。我们还提出了一种关于该群体生物地理历史的假设,认为Alena物种与墨西哥中部密切相关,其祖先可能在过去广泛分布于北美西部,其中只有少数少数群体在冰川避难所幸存下来。

Phylogeny and biogeography of the unique snakefly genus Alena Navás, 1916 (Raphidioptera: Raphidiidae)
The genus Alena Navás, 1916, is considered the most distinct genus of Raphidiidae, because of the uncommon shape of its male genital sclerites and its geographic distribution restricted to the southwestern U.S.A. and western Mexico. Herein, we present a new species of the subgenus Aztekoraphidia U. Aspöck and H. Aspöck, 1970, – Alena (Aztekoraphidia) alanaesp. nov. Based on this discovery we present a detailed morphological study and the first morphological phylogeny of Alena. Our results recover this genus as monophyletic, including the subgenus Aztekoraphidia as sister to a clade composed by the other two monotypic subgenera, Alenas.s. Navás, 1916, and Mexicoraphidia U. Aspöck and H. Aspöck, 1970. We also provide a hypothesis about the biogeographic history of the group, which advocates that species of Alena are strongly associated with central Mexico and their ancestors were probably widely distributed through western North America in the past, of which only a few small groups survived in glacial refuges.
