Περίληψη

Η καταγραφή του Morton το 1905 για το Calopteryx exul Selys, 1853 στη Σεμπντού αποτέλεσε την πρώτη και τελευταία αναφορά του είδους αυτού στη δυτική Αλγερία. Η παρούσα εργασία ανακοινώνει την ανακάλυψη μιας νέας τοποθεσίας εμφάνισης του είδους στη δυτική Αλγερία, στην περιοχή Ουαρσενίς, στις νότιες υπώρειες του δυτικού Τελλιανού Άτλαντα, στο Ουέντ Ελ-Γκέργκα, στον δήμο Γιουσουφία (Τισεμσίλτ).
Κατά τη διάρκεια ερευνών που πραγματοποιήθηκαν τον Σεπτέμβριο του 2022, καταγράφηκαν συνολικά 19 άτομα και 8 εκδύματα του Calopteryx exul σε μήκος 900 μ. του ποταμού Ουέντ Ελ-Γκέργκα (από το σημείο συμβολής του με τον Ουέντ Ελ Άσσα έως τη συμβολή του με τον Ουέντ Μπουραφέδ). Η τοποθεσία αυτή αποτελεί τη δεύτερη γνωστή θέση παρουσίας του απειλούμενου αυτού είδους στα δυτικά της χώρας.
