Diversity and Distribution of the Genus Friesea (Collembola: Neanuridae) in Romania with Description of Three New Species

Abstract

Cristina Fiera and Wanda Maria Weiner (2016) The Romanian Neanuridae is still not well known. In this study we review the Friesea species present in Romania and describe three new species, namely Friesea posada sp. nov., F. mirceai sp. nov. and F. stampa sp. nov. Friesea posada sp. nov. is unique among six other species sharing some morphological characters (6 + 6 eyes, the presence of furca and three anal spines), but the new species has one clavate tenent hair on the tibiotarsi and a reduced mucro which is sometimes absent. The other two species, F. mirceai sp. nov. and F. stampa sp. nov., belong to the group of species characterized by the presence of 5 + 5 eyes, 3 + 3 chaetae on dens and 3 anal spines on Abd. VI. In F. stampa sp. nov. the chaetotaxy of abdominal tergum IV differs, and in F. mirceai sp. nov. the mucro is present and chaeta A1 on tibiotarsus is capitated and longer than the inner edge of claw. Four species are recorded for the first time in Romania: F. emucronata Stach, 1922, F. cf. tolosana Cassagnau, 1958, F. atypica Cassagnau, 1958 and F. aeolica Dallai, 1973. A total of thirteen species of Friesea is reported from Romania and the distribution maps are given for all.
