Comparison of the amplexial morphology of two Argentine populations of Artemia (Crustacea, Anostraca, Artemiidae): A reliable taxonomical tool

In order to facilitate the identification of Artemia sibling species, the morphology of the male and female structures involved in the pre-copulatory embrace (amplexus) of Argentine populations of A. franciscana and A. persimilis was compared. Differences between the species in the female cuticular...

Differences between the species in the female cuticular projections and the frontal knobs of the male second antenna result in differences in the form of the amplexus and in the degree of pressure on the female during amplexus. These characters are helpful tools in the specific identification of live and preserved adults. The usefulness of the shape of the male's second antenna as morphological and morphometrical characters in Artemia taxonomy at the species level is discussed. Copyright © 2006 Magnolia Press.
