Abstract


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(from 8+8 to absence of eyes) of unknown taxonomic meaning that are currently under scrutiny (Jordana & Deharveng, unpublished observations).
Second, the mirabilis group sensu Deharveng & Bedos (1991), distributed worldwide, includes a large number of described and undescribed forms of disputable status, due to the high level of polymorphism which affects most of the taxonomic characters: chaetal arrangement, tenent hair capitation, chaeta morphology, mucro (when reduced), eye number (when reduced). We described here a new species of this group from Algeria.
