New Faunistic Records of Helophoridae, Hydrochidae, and Hydrophilidae (Coleoptera) from the Wetland Habitats of Tekirdağ Province, Türkiye

Turkey’s diverse climate and altitudinal variations support a wide range of habitats, contributing to its rich biological diversity. However, faunistic studies on aquatic beetles, particularly those belonging to the families Helophoridae, Hydrochidae, and Hydrophilidae, remain limited in the wetland ecosystems of Tekirdağ province. To address this knowledge gap, extensive field surveys were conducted in various wetland habitats between September 2022 and July 2023. As a result of these investigations, a total of 38 taxa were identified, comprising 7 species, 1 subspecies from the Helophoridae family, 1 species from the Hydrochidae family, and 28 species, 1 subspecies from the Hydrophilidae family. The findings revealed that all recorded taxa represent new records for Tekirdağ province. This study provides a significant contribution to the faunistic inventory of aquatic beetles in the region and establishes a valuable foundation for a better understanding of the biodiversity of wetland ecosystems in Tekirdağ.
