Chaetocladius callauensis sp. n., C. guardiolei sp. n. and C. parerai sp. n.

These three new species belong to a local ‘Pyrenean element’ based on the following distinguishing characters (mostly atypical) found in the male adult:

Chaetocladius callauensis sp. n.: anal point ( Figs 3A, C, G ) swollen basally, short and bare distally; dorsal part of inferior volsella ( Figs 3 A, F ) unusually rectangular, hyaline and bare apically.
