Abstract: In this study, 1210 adult specimens of the infraorder Gerromorpha (Hemiptera: Heteroptera) were collected from 47 diff erent localities in eastern Anatolia, the region, Valley, and Hatay from 2006 to 2010, and the unpublished materials studied were collected from diff erent parts of Turkey by Seidenstücker, Wellschmied, Demel, and Heinzl, and deposited in the Zoologische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 fi rst recorded from east Anatolia and Gerris maculatus Tamanini, 1946 was the fi rst recorded from the . 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 identifi cation was confi rmed and the redescription of this taxon is given.

Introduction of all of the available records of the infraorders Various studies in Turkey on the infraorder Enicocephalomorpha, Dipsocoromorpha, Gerro- Gerromorpha (Hemiptera: Heteroptera) have morpha, and Nepomorpha. Th e infraorder been done by native and foreign researchers, e.g., Gerromorpha is currently represented in Turkey Lindberg (1922), Fahringer (1922), Hoberlandt by 26 species and 1 subspecies from 9 genera of 5 (1952), Seidenstücker (1957), Kıyak et al. (2004, families (Andersen, 1995; Kıyak and Özsaraç, 2001; 2007, 2008), Kment and Jindra (2005), and Kıyak et al., 2007; Fent et al., 2011). Salur and Mesci (2009). An important source of Gerromorpha are semiaquatic bugs inhabiting the information is the Palaearctic catalogue (Andersen, surface of both stagnant and running water, as well 1995), listing separately the European and Asian as some marshes, shores, and hygropetric habitats. parts of Turkey. Th e fi rst checklist of aquatic and All of the species are predators or scavengers of semiaquatic Heteroptera of Turkey was compiled other arthropods (e.g., Andersen, 1995). Th e current by Kıyak and Özsaraç (2001). Önder et al. (2006) study is the fi rst extensive survey on the infraorder provided a catalogue of Turkish Heteroptera, and Gerromorpha in eastern Anatolia, the Black Sea fi nally, Fent et al. (2011) provided a critical review region, Hatay, and Kelkit Valley. * E-mail: [email protected]

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

Giresun, Hatay, İçel, Iğdır, Kahramanmaraş, Karabük, Tokat and Van; Gerris costai fi eberi for Giresun, Sivas Niğde, Samsun, Sinop, Sivas, Tokat, Van (this paper). and Van; Gerris lacustris for Ağrı, Ardahan, Erzincan, Hatay, Iğdır, Karabük, Samsun, Sinop, Tokat, and Van; Gerris maculatus for Adana, Ağrı, Ardahan, Kayseri, Discussion Sinop, and Van; Gerris thoracicus for Ağrı, Amasya, Examination of the material revealed 15 species Ardahan, Bartın, Çankırı, Erzincan, Giresun, Hatay, from 6 genera and 4 families of Gerromorpha. Th e İçel, Iğdır, Kahramanmaraş, Karabük, Niğde, Samsun, representatives of 4 families, namely Hebridae, Sinop, Sivas, Tokat, and Van; Velia affi nis affi nis for Hydrometridae, Veliidae, and Gerridae, were Amasya, Giresun, Isparta, Malatya, and Niğde; and collected. Th e family Gerridae, which was represented Velia kiritshenkoi for Sinop. by 8 species, was the most common in the collections Some identifi cations of specimens deposited in of this study. the ZSM were reexamined. Th is revealed that the Kıyak and Özsaraç (2001) listed 5 families of specimens originally identifi ed as Hebrus pusillus Gerromorpha from various regions in Turkey. In the (Fallén, 1807) from Konya in fact belong to H. Gerromorpha checklist, 5 families with 8 genera, 26 montanus and the specimens labeled as Gerris species, and 3 subspecies were listed. Aside from the gibbifer Schummel, 1832 from Hatay (İskenderun) checklist by Kıyak and Özsaraç (2001), there are very in fact belong to G. maculatus. Th e occurrence few papers on the semiaquatic true bugs of Turkey. of Gerris gibbifer in Turkey has been considered Th e publications in Turkey were mainly focused only doubtful by Andersen (1995). Based on the nearly on new regional records (Seidenstücker, 1957; Kıyak exclusive allopatry of G. gibbifer and G. maculatus, et al., 2007, 2008; Salur and Mesci, 2009). Finally, Fent Fent et al. (2011) excluded it from Turkish fauna et al. (2011) provided a catalogue of Turkish aquatic based on proven (Hoberlandt 1952) or suspected and semiaquatic Heteroptera, listing 5 families, 9 misidentifi cations of G. maculatus (e.g., Horváth, genera, 26 species, and 1 subspecies of Gerromorpha. 1919; Poisson, 1925; Gadeau de Kerville, 1939; Kıyak In this study, Microvelia hozari, was identifi ed in 1 et al., 2007, 2008). Th e results obtained in this study locality and Hebrus montanus and Gerris caucacicus support Fent et al. (2011). were collected in 2 localities. All of these species Seidenstücker (1957) recorded R. nigricans are rare in Turkey. On the other hand, Hydrometra in İskenderun (Hatay Province), and it has been stagnorum, Velia affi nis affi nis, Aquarius paludum, recorded in Syria, Lebanon, and Jordan (see Fent Gerris costai fi eberi, Gerris lacustris, and Gerris et al., 2011). However, the discovered occurrence thoracicus are common species distributed in all of another species, R. infernalis africana, in Cyprus geographical regions of Turkey. and Israel, previously misidentifi ed as R. nigricans Gerris caucasicus was recorded from Çorum and (cf. Fent et al., 2011), required the reexamination of Sivas provinces by Fent et al. (2011). In this study, Seidenstücker’s specimens to confi rm the species’ Gerris caucasicus, Gerris asper, Gerris lacustris, and identity. Upon this, Seidenstücker’s specimens have Gerris thoracicus are the fi rst recorded from east been reexamined in this study, and these specimens Anatolia and Gerris maculatus is the fi rst recorded have been redescribed for the fi rst time, and the male from the Black Sea region. Kanyukova (1982) genitalia were determined according to Lundblad described G. caucasicus from , Azerbaijan, (1936) as R. nigricans nigricans. Moreover, some and , which neighbor the study area. Here, we other characters of the specimens: 4th antennal follow the fi rst records for the respective provinces: segment shorter than the 3rd, the diff erent character Hydrometra stagnorum for Amasya, Bartın, Çankırı, of setae on legs, and color on dorsal body parts agree Gümüşhane, Iğdır, Kahramanmaraş, Samsun, Sinop, with R. nigricans nigricans. Th e world distribution and Tokat; Hebrus montanus for Konya; Aquarius of R. nigricans nigricans is mostly in the Palaearctic, paludum for Amasya, Bartın, Iğdır, Samsun, Sinop, Ethiopian, and Oriental regions. Rhagovelia nigricans Kahramanmaraş; Aquarius ventralis for Samsun, has been reported by Seidenstücker only in 1 locality Sinop, and İçel; Gerris argentatus for Kahramanmaraş from Hatay (İskenderun), and is identifi ed as a rare and Sinop; Gerris asper for Ağrı; Gerris caucasicus for species in Turkey, although we may expect its further
