Hydrodroma angelieri (Acari, Hydrachnidia: Hydrodromidae) a new water mite species from Corsica based on morphological and DNA barcode evidence

In the present study we used morphological data and DNA barcodes to describe a new species, Hydrodroma angelieri sp. nov. from Corsica, France. A high genetic distance of 17.3 +/- 0.017% K2P from its molecularly most closely related European congener, H. despiciens (Muller, 1776), supports H. angelieri sp. nov. as a distinct species. Morphologically the new species can be identified on the basis of relatively small leg claws, the presence of only one swimming seta on II-L-5 and 4-6 swimming setae on the anterior surface of IV-L-5. An updated key for the European species of Hydrodroma is provided.

Automated summary

In this study, we have described a new species, Hydrodroma angelieri sp. nov. from Corsica, France, using morphological data and DNA barcodes. The high genetic distance and distinct morphological characteristics support its status as a distinct species. Additionally, an updated key for the European species of Hydrodroma has been provided.
