A new Friesea of the mirabilis-group from Algeria (Collembola: Neanuridae: Frieseinae)

摘要

As noted in a previous paper (Deharveng & Hamra-Kroua 2004), Friesea are well diversified in Eastern Algeria. This fauna includes species from two different taxonomic groups. First, a complex of forms closely related to Friesea afurcata Denis, 1926 includes Friesea ladeiroi Gama, 1959 and Friesea laouina Deharveng & Hamra-Kroua, 2004 in the studied region. They exhibit various degrees of intra-population eye reduction (from 8+8 to absence of eyes) of unknown taxonomic meaning that are currently under scrutiny (Jordana & Deharveng, unpublished observations).
