Contributions to the Knowledge on Aquatic/Semi-Aquatic Coleoptera (Insecta) Fauna of Turkey with First Records in Turkish Thrace

Abstract

In the present study, adult specimens belonging aquatic/semi-aquatic coleopteran collected from 1986 to 2002 in Turkish Thrace were evaluated taxonomically. Altogether, a total of 23 species belonging to the families Dytiscidae, Haliplidae, Noteridae, Gyrinidae, Helophoridae and Hydrophilidae were determined. A total of 12 species Hydaticus (Hydaticus) aruspex Clark, 1864, Aulonogyrus concinnus (Klug 1834), Cercyon (Cercyon) littoralis Gyllenhal 1808, Gyrinus (Gyrinus) distinctus Aubé 1836, G. (Gyrinus) substriatus Stephens 1829, Haliplus (Liaphlus) flavicollis Sturm 1834, Helophorus (Helophorus) grandis Illiger 1798, Hydrochara flavipes (Steven 1808), Laccobius (Laccobius) minutus (Linnaeus 1758), Laccophilus hyalinus (De Geer 1774), Platambus maculatus (Linnaeus 1758), Rhantus (Rhantus) suturalis (MacLeay 1825) were determined for the first time from Turkish Thrace. The aquatic habitat distributions of the species were also compared by the statistically using Shannon-Wiener diversity index and Bray-Curtis similarity index.
