1 Research Article Turk J Zool 2012; 36(5): TÜBİTAK doi: /zoo Additional records of Gerromorpha (Hemiptera: Heteroptera) and redescription of Rhagovelia nigricans nigricans (Burmeister, 1835) from Anatolia (Turkey) Ahmet DURSUN* Department of Biology, Faculty of Arts and Science, Amasya University, Amasya - TURKEY Received: Accepted: 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47 different localities in eastern Anatolia, the Black Sea region, Kelkit Valley, and Hatay from 2006 to 2010, and the unpublished materials studied were collected from different parts of Turkey by Seidenstücker, Wellschmied, Demel, and Heinzl, and deposited in the Zoologische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. Key words: Turkey, Gerromorpha, fauna, Rhagovelia nigricans nigricans, faunistic records Introduction Various studies in Turkey on the infraorder Gerromorpha (Hemiptera: Heteroptera) have been done by native and foreign researchers, e.g., Lindberg (1922), Fahringer (1922), Hoberlandt (1952), Seidenstücker (1957), Kıyak et al. (2004, 2007, 2008), Kment and Jindra (2005), and Salur and Mesci (2009). An important source of information is the Palaearctic catalogue (Andersen, 1995), listing separately the European and Asian parts of Turkey. The first checklist of aquatic and semiaquatic Heteroptera of Turkey was compiled by Kıyak and Özsaraç (2001). Önder et al. (2006) provided a catalogue of Turkish Heteroptera, and finally, Fent et al. (2011) provided a critical review * ahmet.dursun@amasya.edu.tr of all of the available records of the infraorders Enicocephalomorpha, Dipsocoromorpha, Gerromorpha, and Nepomorpha. The infraorder Gerromorpha is currently represented in Turkey by 26 species and 1 subspecies from 9 genera of 5 families (Andersen, 1995; Kıyak and Özsaraç, 2001; Kıyak et al., 2007; Fent et al., 2011). Gerromorpha are semiaquatic bugs inhabiting the surface of both stagnant and running water, as well as some marshes, shores, and hygropetric habitats. All of the species are predators or scavengers of other arthropods (e.g., Andersen, 1995). The current study is the first extensive survey on the infraorder Gerromorpha in eastern Anatolia, the Black Sea region, Hatay, and Kelkit Valley. 652

2 A. DURSUN Materials and methods The research material consisted of 1210 adult Gerromorpha specimens collected from 47 localities including lakes, marshes, ponds, rivers, and streams from various aquatic habitats, in the provinces of Ağrı, Amasya, Ardahan, Bartın, Erzincan, Erzurum, Giresun, Gümüşhane, Hatay, Iğdır, Karabük, Samsun, Sinop, Sivas, Tokat, and Van, in Anatolia, Turkey, from 2006 to 2010 (see Table). Furthermore, the unpublished material previously collected in different parts of Turkey by the late Seidenstücker, Wellschmied, Demel, and Heinzl, which is preserved in the Zoologische Staatssammlung München (ZSM), Germany, were examined. The geographical distributions of the particular species follow Andersen (1995) and Fent et al. (2011). The specimens were collected with a sieve, ladle, or net having a 1-mm mesh size. Coordinates of the collection locations were logged with a handheld Garmin Etrex Vista global positioning system. Male genitalia were used to verify identification of some of the species. Prior to removal of the genitalia, samples were softened in 5% acetic acid (CH 3 COOH). The keys by Stichel (1955, 1956), Seidenstücker (1957), Tamanini (1958), Kerzhner and Jaczewski (1967), Kanyukova (1982, 1997), and Linnavuori and Hosseini (1999) were followed for identification. During the identification process, several species were compared with specimens held in the ZSM. The specimens examined have been preserved at the Biology Department of the Faculty of Arts and Science, Amasya University, Amasya, Turkey. Table.

Comments: Seidenstücker (1957) recorded R. nigricans from Hatay. Fent et al. (2011) accept the occurrence of the genus Rhagovelia in Anatolia; however, it is essential to reexamine Seidenstücker s specimens to see whether they really belong to R. nigricans or R. infernalis africana Lundblad, 1936, a taxon recently recorded from Cyprus and Israel (see Fent et al., 2011).

9 Additional records of Gerromorpha (Hemiptera: Heteroptera) and redescription of Rhagovelia nigricans nigricans (Burmeister, 1835) from Anatolia (Turkey) Giresun, Hatay, İçel, Iğdır, Kahramanmaraş, Karabük, Niğde, Samsun, Sinop, Sivas, Tokat, Van (this paper). Discussion Examination of the material revealed 15 species from 6 genera and 4 families of Gerromorpha. The representatives of 4 families, namely Hebridae, Hydrometridae, Veliidae, and Gerridae, were collected. The family Gerridae, which was represented by 8 species, was the most common in the collections of this study. Kıyak and Özsaraç (2001) listed 5 families of Gerromorpha from various regions in Turkey. In the Gerromorpha checklist, 5 families with 8 genera, 26 species, and 3 subspecies were listed. Aside from the checklist by Kıyak and Özsaraç (2001), there are very few papers on the semiaquatic true bugs of Turkey. The publications in Turkey were mainly focused only on new regional records (Seidenstücker, 1957; Kıyak et al., 2007, 2008; Salur and Mesci, 2009). Finally, Fent et al. (2011) provided a catalogue of Turkish aquatic and semiaquatic Heteroptera, listing 5 families, 9 genera, 26 species, and 1 subspecies of Gerromorpha. In this study, Microvelia hozari, was identified in 1 locality and Hebrus montanus and Gerris caucacicus were collected in 2 localities. All of these species are rare in Turkey. On the other hand, Hydrometra stagnorum, Velia affinis affinis, Aquarius paludum, Gerris costai fieberi, Gerris lacustris, and Gerris thoracicus are common species distributed in all geographical regions of Turkey. Gerris caucasicus was recorded from Çorum and Sivas provinces by Fent et al. (2011). In this study, Gerris caucasicus, Gerris asper, Gerris lacustris, and Gerris thoracicus are the first recorded from east Anatolia and Gerris maculatus is the first recorded from the Black Sea region. Kanyukova (1982) described G. caucasicus from Armenia, Azerbaijan, and Georgia, which neighbor the study area. Here, we follow the first records for the respective provinces: Hydrometra stagnorum for Amasya, Bartın, Çankırı, Gümüşhane, Iğdır, Kahramanmaraş, Samsun, Sinop, and Tokat; Hebrus montanus for Konya; Aquarius paludum for Amasya, Bartın, Iğdır, Samsun, Sinop, Kahramanmaraş; Aquarius ventralis for Samsun, Sinop, and İçel; Gerris argentatus for Kahramanmaraş and Sinop; Gerris asper for Ağrı; Gerris caucasicus for Tokat and Van; Gerris costai fieberi for Giresun, Sivas and Van; Gerris lacustris for Ağrı, Ardahan, Erzincan, Hatay, Iğdır, Karabük, Samsun, Sinop, Tokat, and Van; Gerris maculatus for Adana, Ağrı, Ardahan, Kayseri, Sinop, and Van; Gerris thoracicus for Ağrı, Amasya, Ardahan, Bartın, Çankırı, Erzincan, Giresun, Hatay, İçel, Iğdır, Kahramanmaraş, Karabük, Niğde, Samsun, Sinop, Sivas, Tokat, and Van; Velia affinis affinis for Amasya, Giresun, Isparta, Malatya, and Niğde; and Velia kiritshenkoi for Sinop. Some identifications of specimens deposited in the ZSM were reexamined. This revealed that the specimens originally identified as Hebrus pusillus (Fallén, 1807) from Konya in fact belong to H. montanus and the specimens labeled as Gerris gibbifer Schummel, 1832 from Hatay (İskenderun) in fact belong to G. maculatus. The occurrence of Gerris gibbifer in Turkey has been considered doubtful by Andersen (1995). Based on the nearly exclusive allopatry of G. gibbifer and G. maculatus, Fent et al. (2011) excluded it from Turkish fauna based on proven (Hoberlandt 1952) or suspected misidentifications of G. maculatus (e.g., Horváth, 1919; Poisson, 1925; Gadeau de Kerville, 1939; Kıyak et al., 2007, 2008). The results obtained in this study support Fent et al. (2011). Seidenstücker (1957) recorded R. nigricans in İskenderun (Hatay Province), and it has been recorded in Syria, Lebanon, and Jordan (see Fent et al., 2011). However, the discovered occurrence of another species, R. infernalis africana, in Cyprus and Israel, previously misidentified as R. nigricans (cf. Fent et al., 2011), required the reexamination of Seidenstücker s specimens to confirm the species identity. Upon this, Seidenstücker s specimens have been reexamined in this study, and these specimens have been redescribed for the first time, and the male genitalia were determined according to Lundblad (1936) as R. nigricans nigricans. Moreover, some other characters of the specimens: 4th antennal segment shorter than the 3rd, the different character of setae on legs, and color on dorsal body parts agree with R. nigricans nigricans. The world distribution of R. nigricans nigricans is mostly in the Palaearctic, Ethiopian, and Oriental regions. Rhagovelia nigricans has been reported by Seidenstücker only in 1 locality from Hatay (İskenderun), and is identified as a rare species in Turkey, although we may expect its further 660
