Agapetus quinonesi (Trichoptera: Glossosomatidae), a new species from southern Spain, with notes on the Iberian species of the A. incertulus group

A new species, Agapetus quinonesi (Trichoptera: Glossosomatidae), is described and illustrated based on male specimens from southern Spain. The new species belongs to the taxonomically challenging A. incertulus species group and shows its closest affinities to the Iberian endemic A. theischingeri. It can be readily distinguished from congeners by a unique combination of characters in the male genitalia, particularly the shape of segment X, the morphology of the inferior appendages, and the configuration of the phallic apparatus. New data on habitat preferences and distribution are provided, and comparative taxonomic notes on the Iberian representatives of the A. incertulus group are presented. The discovery of this species further highlights the biogeographical significance of southern Iberia, and especially the Baetic Cordillera, as a hotspot of trichopteran diversity and endemism.
