Annotated catalogue of Enicocephalomorpha, Dipsocoromorpha, Nepomorpha, Gerromorpha, and Leptopodomorpha (Hemiptera: Heteroptera) of Turkey, with new records

An annotated check-list of the aquatic and semi-aquatic bugs of the infraorders Enicocephalomorpha, Dipsocoromorpha, Nepomorpha, Gerromorpha, and Leptopodomorpha of Turkey and its geographical parts (Turkish Thrace [i.e., European Turkey] and Anatolia [i.e., the Asian Turkey]) is presented. The nomenclatoric history of Alpagut Kıyak, 1995 (= Harpago Linnavuori, 1951, = Raunocoris Baena & Alonso-Zarazaga, 2009) is reviewed, its gender is fixed, and two new combinations are proposed: Alpagut maroccanus (Wagner, 1960) comb. nov., and Alpagut medius (Rey, 1888) comb. nov. The list is based on a survey of all published records as well as on examination of collection material, including recent material collected in the poorly explored Turkish Thrace. The following numbers of species are accepted as occurring in Turkey: Enicocephalomorpha—1 species (Asian Turkey only), Dipsocoromorpha—2 species (Asian Turkey only), Nepomorpha—49 species (29 in European and 47 in Asian Turkey), Gerromorpha—27 species (10 in European and 25 in Asian Turkey), and Leptopodomorpha—21 species (6 in European and 20 in Asian Turkey). Forty species are known from both European and Asian Turkey, whereas 5 are recorded only from European Turkey and 55 only from Asian Turkey. Eight species and subspecies, Micronecta scholtzi (Fieber, 1860), Hesperocorixa sahlbergi (Fieber, 1848), Sigara iranica Lindberg, 1964, Hebrus ruficeps Thomson, 1871, Velia affinis filippii Tamanini, 1947, Velia rhadamantha rhadamantha Hoberlandt, 1941, Gerris kabaishanus Linnavuori, 1998, and Saldula pilosella pilosella (Thomson, 1871), are reported from Turkey for the first time; and four species, Sigara scripta (Rambur, 1840), Corixa punctata (Illiger, 1807), C. panzeri (Fieber, 1848), and Gerris argentatus Schummel, 1832, are new records for Turkish Thrace. First exact localities of several other species are provided as well. Three species, Sigara kervillei (Poisson, 1927), Microvelia hozari Hoberlandt, 1952, and Velia mariae Tamanini, 1971, seem to be endemic to Anatolia; 22 species occur only in Turkey and the adjacent regions (Balkan Peninsula, Cyprus, Near East, Iran, and Transcaucasia). The 75 remaining species have a wider distribution. Occurrences of 10 species, previously recorded from Turkey, need further confirmation. Finally, 19 species-group taxa are excluded from Turkish fauna as they are based on proven or suspected misidentifications or taxonomic confusion: Micronecta minutissima (Linnaeus, 1758), Cymatia bonsdorffii (C. R. Sahlberg, 1819), Arctocorisa carinata carinata (C. R. Sahlberg, 1819), Callicorixa praeusta praeusta (Fieber, 1848), Hesperocorixa castanea (Thomson, 1869), Hesperocorixa occulta (Lundblad, 1929), Sigara hoggarica Poisson, 1929, Sigara scotti (Douglas & Scott, 1868), Heleocoris minusculus (Walker, 1870), Anisops debilis canariensis Noualhier, 1893, Velia caprai caprai Tamanini, 1947, Aquarius najas (De Geer, 1773), Gerris costae costae (Herrich-Schaeffer, 1850), G. gibbifer Schummel, 1832, G. lateralis Schummel, 1832, Saldula fucicola (Sahlberg, 1870), S. pilosella hirsuta (Reuter, 1888), Salda morio Zetterstedt, 1838, and S. muelleri (Gmelin, 1790). In addition, first records of Aquarius ventralis (Fieber, 1860) from Syria, and Saldula melanoscela (Fieber, 1859) and Leptopus marmoratus (Goeze, 1778) from Lebanon, are provided. The previously published records of Rhagovelia nigricans nigricans (Burmeister, 1835) from Cyprus and Israel (Hoberlandt 1952b) belong to R. infernalis africana Lundblad, 1936.

Genetic diversity, taxonomy, and phylogeography of the western Palaearctic water strider Aquarius najas (DeGeer) (Heteroptera: Gerridae)

Genetic diversity and phylogeography was surveyed for the western Palaearctic water strider (Heteroptera, Gerridae) Aquarius najas (DeGeer) based on almost 780 bp of DNA sequence data from the mitochondrial gene encoding cytochrome oxidase c subunit I from 62 specimens sampled throughout its distribution area, and including the two related species A. cinereus (Puton) (6 specimens) and A. ventralis (Fieber) (3 specimens). 34 unique haplotypes were found for A. najas (55%), 5 for A. cinereus (83%), and 3 for A. ventralis (100%). A strict consensus tree obtained after a maximum parsimony analysis of the unique haplotypes was well resolved, and showed that while monophyly of A. ventralis was strongly supported, A. najas and A. cinereus were not reciprocally monophyletic in their mtDNA, since two clades from North Africa include a mixture of both species, and one specimen of A. cinereus from Sicily could not be assigned to any clade. All haplotypes were geographically well structured, and only one A. najas haplotype was widely distributed. This haplotype belongs to a clade with very little sequence divergence, which is distributed throughout Central and northern Europe, but includes also populations from northern Italy and northern Greece, thus indicating one or two possible refuges during the Pleistocene glaciations. Specimens from the Iberian Peninsula and Mallorca comprised a sistergroup to this clade, and show that the Iberian refugium did not contribute to the fauna of other parts of the European continent. Around the Mediterranean the sequence divergences for A. najas were much higher, especially in the Balkans, and on the islands Crete and Corsica. Whether the occurrence of these highly distinct lineages around the Mediterranean is due to extinction - or insufficient sampling - of intermediate haplotypes, or whether it indicates presence of unrecognized sibling species of A. najas and A. cinereus clearly needs further investigation.
