Title: | Main Title: Phylogenetic exploration on the genetic diversity of Maindronia neotropicalis (Zygentoma: Maindroniidae) - an enigmatic Gondwanean relict from the Atacama Desert. |
Description: | Abstract: The genus Maindronia currently consists of only three described species from desert biomes in Sudan, Arabian Peninsula and Chile. The distribution range of these bizarre insects (Sudan, Arabian Peninsula and Chile ) is unique for closely related arthropods and suggests the presence of a Gondwanean relict group. In Chile, Maindronia neotropicalis inhabits only the Atacama Desert. Previously published collecting data indicated that M. neotropicalis is a silverfish adapted to live in hyperarid areas but the distribution and genetic diversity of this taxon is poorly studied. Extensive sampling in the Atacama Desert revealed a considerable number of populations of Maindronia which are, however, entirely restricted to the coastal Atacama. Analyses of mitochondrial sequences allowed for the first time insights into the evolutionary history of M. neotropicalis. In fact, the data suggest the presence of three well-separated lineages in the Chilean Atacama Desert. Among the collected specimens, we found individuals with a size of about 70 mm (including the long cerci); by far the largest size ever observed in silverfish. The deep divergence of the three extremophile lineages suggests a rather old origin of these clades. |
