Abstract
Based on the extensive material recently collected on the Island of Rhodos, Greece (terra typica) in May, 2005, a redescription of Procloeon (Pseudocentroptilum) fascicaudale (Sowa, 1985) is presented. Larval characters are completed, female subimago described and the egg chorionic structures illustrated by means of scanning electron microscopy for the first time. Variability in color patterns and critical characters distinguishing eggs, larvae and male imagines from other Westpalaearctic species of the subgenus Pseudocentroptilum Bogoescu, 1947 (the representatives of the Procloeon (Pseudocentroptilum) motasi species-group in particular) are described and discussed. Distributional patterns of the species, its abundance, possible faunistic origin, some aspects of larval and imago’s biology, and life cycle of the species are briefly stated. Delimitation and recent concepts of the taxa Procloeon Bengtsson, 1915 and Pseudocentroptilum within the subfamily Cloeoninae Kazlauskas, 1972, taxonomic position and affinities of P. fascicaudale are discussed.References
