Abstract. The focus of this study is to display the faunistic, ecological and zoogeographical status of Elateridae fauna from the middle part of the Blacksea Region in Turkey. Materials are specimens collected from 2006 to 2009 during fi eld studies, as well as the species -of which localities are unpublished-received from the private collection of Dr. Giuseppe Platia and the species present in the available literature. 54 species of 21 genera belonging to 6 subfamilies of Elateridae were recorded in the collected specimens. Along with the species present in literature and the private collection, the total material representing the study area was shown to comprise six subfamilies, 24 genera and 73 species. Number of specimens, collecting habitats-methods, months, altitudes are given in tables and graphs for collected species. Distributions of species in other regions of Turkey and zoogeographical regions are also given in tables and graphs for all species. Diversity of the collected species and collecting habitats-methods were compared by using Shannon-Wiener diversity index. Zoogeographical status of all species were discussed. Guglielmi & Platia (1985), Kesdek et al. (2006), Mertlik (2000, Dusanek & Mertlik (2007) and Platia & Gudenzi (1996, 1998, 1999, 2002, 2004 on Elateridae family include species from research area, these studies do not thoroughly display Elateridae fauna, its ecological and zoogeographical profi le of the research area.
RésuméTh e research area covers middle part of Blacksea region, which includes Amasya, Çorum. Ordu, Samsun and Tokat provinces from Middle Blacksea region and Sinop province from Western Blacksea region (Fig. 1 Research area is located in Euro-Siberian and IranoTuranian (central anatolia) phytogeographical regions. Euro-Siberian region is largely represented by the Euxine province that extends throughout most of Caucasia, mountain Crimea and Dobrudja. Th is is basically a belt of broad-leaved deciduous forests, penetrated by conifers at higher altitudes. It is most closely related (especially in the east) to the Hyrcanian province of Northern Iran and adjacent Talysch, but also has many connections with the Balkans and central Europe, and even with Atlantic Europe (Davis et al. 1971). IranoTuranian region is by far the largest of the three regions in Turkey and, apart from a few enclaves is confi ned to Central and East Anatolia. Although it is a large area rich in herbaceous and suff ruticose species, it is not well understood than the Mediterranean and EuroSiberian regions. Th is is largely due to the diffi culties of identifi cation in several genera that play an important role in the vegetation. Th e broad forest zone of Pinus nigra Arnold. subsp. pallasiana (Lamb.) borders Central Anatolia in the Wild north, west and south. Th is forest meets the oak scrub (especially Quercus pubescens Wild in the north and west, Q. infectoria Oliver sensu lato mainly in the west and south and Q. Cerris L.), the most abundant type of vegetation on the periphery of the central Anat...
