Protonemura angelieri Berthelemy 1963

Protonemura cf. angelieri Berthélemy, 1963 TAXO-2022. This taxon was only caught at the larval stage at site C (three larvae, 21 IX 2022). These larvae are morphologically closed to P. angelieri (sensu Berthélemy 1982), a rare and micro-endemic species from central part of the Pyrenees, but also to Protonemura vandeli Berthélemy, 1963, and presents specificities regarding the length of dorso-abdominal setae and gill’s constriction. We suspected that these three larvae correspond to P. angelieri but adult capture is necessary to validate the species. Unfortunately, molecular analyses failed on the three individuals, potentially due to unsuitable COI primers for this species. DIST. P. angelieri is native to torrents at medium and high altitudes (Vinçon and Ravizza 2005), and have been collected by Lavandier (1979) at sites D and a 5, i. e. downstream reaches, close to where we potentially collected it (site C, see above).
