Redescription of Gammarus odettae Mateus & Mateus, 1990 (Amphipoda, Gammaridae) from Turkey with some taxonomic notes

Abstract Gammarus odettae was first identified in 1990 by Mateus & Mateus, using specimens collected from the provinces of Ankara, Bursa and Balıkesir in Turkey. Since then, there have been no taxonomic studies on G. odettae , nor any records from other regions. In this study, specimens of G. odettae were collected from decaying plant debris in slow-flowing streams in the provinces of Ordu and Samsun in Turkey. The records in this study represent the second recorded sighting of this species. G. odettae specimens were detected in locations different from their type locality and provided a detailed morphological redescription along with drawings of the species.
