Additional records of Gerromorpha (Hemiptera: Heteroptera) and redescription of Rhagovelia nigricans nigricans (Burmeister, 1835) from Anatolia (Turkey)


Abstract: In this study, 1210 adult specimens of the infraorder Gerromorpha (Hemiptera: Heteroptera) were collected from 47 different localities in eastern Anatolia, the Black Sea region, Kelkit Valley, and Hatay from 2006 to 2010, and the unpublished materials studied were collected from different parts of Turkey by Seidenstücker, Wellschmied, Demel, and Heinzl, and deposited in the Zoologische Staatssammlung München. In this study, 6 genera of 4 families and 15 species were recorded. Of those, 13 were new records for the research areas. Furthermore, Gerris lacustris (Linnaeus, 1758), Gerris thoracicus Schummel, 1832, Gerris asper (Fieber, 1860), and Gerris caucasicus Kanyukova, 1982 were the first recorded from east Anatolia and Gerris maculatus Tamanini, 1946 was the first recorded from the Black Sea region. In addition, recently doubted specimens that are related to the given record, called Rhagovelia nigricans nigricans (Burmeister, 1835) by Seidenstücker (1957) from Hatay (Iskenderun), were reexamined and their species identification was confirmed and the redescription of this taxon is given.
