INTRODUCTION

The water scavenger beetles (Hydrophilidae) represent one of the most ecologically diverse groups of Coleoptera, containing nearly 2900 species distributed worldwide (Short and Fikáček, 2013). Zoogeographically hydrophilids have a wide range of distribution and are classified into six subfamilies including Hydrophilinae, Chaetarthriinae, Enochrinae, Acidocerinae, Rygmodinae and Sphaeridiinae (Yılmaz and Aslan, 2014). Five of them inhabit the Palearctic region. Uptill now 19 genera, 95 species and 4 subspecies within five subfamilies of Hydrophilids have been recorded from Turkey (Mart, 2009; Mart et al., 2014b).

Bingöl province is located in the southwest of Eastern Anatolia Region, in North Euphrate part between 38o 27’ and 40o 27’ East longitude and 41o 20’ and 39o 54’ North latitude. It is quite rugged and high landform within provincial boundaries, where altitude exceeds 1250 meters above sea level. Four sides of Bingol Plain are surrounded by mountains, which occupies the highest parts of the mountains of glacial lakes, the remnants of the moraine occupies foothills of the mountains.

MATERIALS AND METHODS

The specimens of beetles were collected by means of a sieve and net with 1 mm pores from shallow areas of various springs, streams, brackish water ponds and wet habitats near the water in Bingöl province between May 2003 and October 2004. The beetles were killed using ethyl acetate or 70% alcohol solution. Diagnosis of beetles was carried out using male genitalia (aedeagophores) and some other important morphological characters. All the specimens were identified to species using keys and figures given by Hansen (1987), (1991), (1999), Shatrovskiy (1984), Gentili (1975), (1979), (2000), Gentili and Chiesa (1975), Schödl (1991), (1993), Hebauer (1994) and (1998). Aedeagophores were dissected out under a stereo microscope and cleared in 10% KOH solution for 1-2 h. Photographs of the main diagnostic characters and male genitalia were made using Olympus SZX16 microscope. All samples have been deposited in the Zoological Museum, Atatürk University, Erzurum, Turkey.

RESULTS

A total of 29 species and 2 subspecies belonging to 5 subfamilies of the family Hydrophilidae were identified and are listed below. Three species are here recorded for the first time from Bingöl province of Turkey. In addition, the new locality records for the species has been known previously from Turkey.

Family Hydrophilidae

The water scavenger beetles (family Hydrophilidae) are the largest group of the superfamily Hydrophiloidea, comprising about 2500 known species. The family is known for its aquatic representatives, which are often abundant in most kinds of stagnant waters, but also commonly inhabit streams, rivers and seepage habitats. Besides these aquatic species, the family also contains terrestrial taxa that inhabit mostly leaf litter and other kinds of decaying organic material. Within the Palaearctic region, most terrestrial species inhabit excrements of various herbivorous or omnivorous mammals (e.g. cows, goats, deer, bears etc.). Most aquatic species are classified in the subfamily Hydrophilinae and most terrestrial ones in the subfamily Sphaeridiinae, but there are many exceptions in both subfamilies. Adult beetles are mostly saprophagous, feeding on different kinds of decaying organic matter, whereas larvae are predaceous, preying on various invertebrates (Fikáček et al., 2010).

DISCUSSION

In the present study, totally 31 taxa belonging to Hydrophilidae of aquatic Coleoptera were listed in Bingöl province. Of these, Laccobius (Dimorpholaccobius) obscuratus obscuratus, Enochrus (Lumetus) segmentinotatus, Laccobius (Dimorpholaccobius) hauserianus were recorded for the first time in Bingöl province.

The total number of Hydrophilidae species recorded from Bingöl is nearly 1/3 of the whole Turkish fauna. But, this number does not reflect the fauna of research area in real sense. Because, the high plateaus contains habitats for favorable conditions to all aquatic insects, while the higher parts of the mountains surrounding of the research area involves a number of different sizes glacial lakes. For determining the real sense of Hydrophilidae fauna of Bingöl province, and to contribute to the coleopteran fauna of world, there is a need to collect a series of samples from aquatic habitats in the places which are quite difficult to reach.

Faunistic studies on Turkish Aquatic Coleoptera has been increased recently (Mart, 2009; Darılmaz and Incekara, 2011; Mart et al., 2014a, b; Yılmaz and Aslan, 2014; Darılmaz et al., 2015), but with further studies to improve our knowledge on Turkish water beetles, and filling gaps in our knowledge on diversity of water beetles more focus should be laid on little known and specific areas, places which are quite difficult to reach.
