ABSTRACT

The present study was carried out from September 2013 to August 2015 in Bingöl and Diyarbakır provinces in the Eastern and South-eastern Anatolian regions of Turkey. A total of 3,990 dysticid specimens were collected from 118 different localities and identified. In total, 40 species in 17 genera of family Dytiscidae were recorded, of which 37 were new to the study area. Eretes sticticus (Linnaeus, 1767) is the second record for Turkish fauna. Furthermore, Hydroporus inscitus Sharp, 1882 is new record for the Turkish fauna.

Introduction

 

The family Dytiscidae Leach, 1815 is a conspicuous important component of aquatic beetles. The members of this family are known as predaceous diving beetles and could be found in all type of fresh water habitats. The family is represented by 182 genera and approximately 4,450 species, which are distributed around the world (Nilsson and Hájek, 2017a). In the Palearctic region, it is represented by 15 tribes, 80 genera and approximately 600 species (Nilsson and Hájek, 2017b). Darılmaz and Kıyak (2009a) listed 28 genera and 136 species from Turkey. With subsequent studies (Darılmaz and Kıyak, 2009b; Fery and Erman, 2009; Fery, 2009; Fery and Hendrich, 2011a, b; Fery and Przewozny, 2011; Hájek et al., 2011; Hernando et al., 2012; Vorst and Fery, 2014; Aykut and Fery, 2017) this value increased by 20 and reached to 156. Of these 36 are endemic to Turkey (Aykut and Fery, 2017; Nilsson and Hajek, 2017a). Up to now considerable faunistic studies of diving beetles have been conducted in Turkey and as a result; 32 of the 81 provinces have been studied (Fig. 1). Up to now, only a single study about Water Scavenger beetles (Coleoptera: Hydrophilidae) have been conducted in Bingöl Province (Mart and Erman, 2017). There isn’t such any study in the remaining 49 provinces. Especially in south eastern region of Anatolia, (Diyarbakır is located in this region) we couldn’t find any faunistic study about this family. According to our investigations, only four species from Bingöl [Agabus biguttatus (Olivier, 1795), Graptodytes veterator behningi Zaitzev, 1927, Scarodytes halensis (Fabricius, 1787) and Scarodytes costates, Aykut and Fery, 2017] and six species from Diyarbakır [Agabus faldermanni Zaitzev, 1927, Ilybius chalconatus (Panzer, 1796), Deronectes evelynae Fery and Hosseinie, 1998, Deronectes syriacus Wewalka, 1970, Graptodytes sedilloti phrygius Guignot, 1942 and Hygrotus lernaeus (Schaum, 1857)] have been reported so far. The aim of this study was to determine the diving beetles fauna of Bingöl and Diyarbakır provinces of Turkey.

 

Materials and Methods

Description of the study area

Diyarbakır province is located in the northern part of the South-eastern region of Anatolia, with an area of 15,188 km2. The altitude at the city centre is 674 m. It is generally surrounded by mountains, and the middle has a slightly hollowed outlook. The southern part of the city is covered by extensive farmlands while the northern parts with mountainous terrains. Bingöl province is located in the Eastern Anatolian region of Turkey and has a surface area of 8.253 km2 with a large number of aquatic sites with high altitudes. The altitude at the city centre is 1,159 m (Fig. 2).

Materials

Specimens were collected from freshwater habitats in Bingöl and Diyarbakır provinces (Turkey) using a net with a mesh diameter of 0.5 mm from 2013 to 2015 (Supplementary Table I). Seven field trips were carried out during the study period. In Diyarbakır province, a total of 135 samplings were performed at 58 different localities.


 

 

In Bingöl province, 105 samplings were performed at 60 different localities. The coordinates and altitude information of the localities were taken directly from a handheld GPS tool (Magellan Explorist 610). As a result of these seven field trips and 240 samplings, 3,990 specimens were collected. The collected specimens were fixed and preserved in 70% ethyl alcohol solution at spot. The clay and muddy substances on their surfaces were brushed off with a small paintbrush in the laboratory, and each specimen was checked for identification. Confirmation of the identified species was performed in part by Dr. Hans Fery (Berlin, Germany). The examined materials have been deposited in the private collection of the author at Dicle University, Diyarbakır, Turkey.

 

Results

 

A total of 3,390 adults of 40 species in 17 genera of family Dytiscidae were collected and described from the study area. The species are listed in Supplementary Table II. Of 34 identified species in Diyarbakır province, 31 were new for the South-eastern Anatolian region of Turkey, and 6 of 36 identified species in Bingöl were new to the Eastern Anatolian region of Turkey. Eretes sticticus (Linnaeus, 1767) was the second record for Turkey. Hydroporus inscitus Sharp, 1882 was the first record for Turkey. By now, 37 dytiscid species are known from Bingöl province, 40 species from Diyarbakır province and 157 species from Turkey. The determined species and their locality data are listed below:

Discussion

 

In the freshwater habitats of Bingöl and Diyarbakır provinces 40 diving beetle species belonging to 17 genera were recorded. Of these Hydroporus inscitus Sharp, 1882 was recorded from Turkey for the first time, while Eretes sticticus (Linnaeus, 1767) was recorded for the second time. The total number of specimens of diving beetles collected from the research area amounts to 3.990. Scarodytes halensis was the most dominant species (11.77%), followed by Agabus bipustulatus (6.66%), A. biguttatus (6.19%), Hydroglyphus geminus (5.75%) and Laccophilus hyalinus (5.48%). Agabus didymus, Eretes sticticus, Hydroporus inscitus, H. Kozlovskii, Hygrotus armeniacus, Nebrioporus airumlus, Oreodytes davisii, Platambus lunulatus, P. maculatus and Rhantus suturalis has an abundance of less than 1%. The remaining 25 species were subdominant with an abundance of 1-5 %.

Agabus bipustulatus, A. biguttatus, Hydroglyphus geminus, Hydroporus transgradiens, Hygrotus inaequalis, Scarodytes halensis and Laccophilus hyalinus were the most widespread species found in our study area. These seven species were found, respectively: A. bipustulatus in 43 sites, A. biguttatus and Hydroglyphus geminus in 29 sites, Hydroporus transgradiens in 28 sites, H.inaequalis in 26 sites, Scarodytes halensis and Laccophilus hyalinus in 25 sites. In contrast to these species; Eretes sticticus, Hydroporus inscitus and Hygrotus armeniacus were restricted to a single site each. Additional studies are required to better understand the overall distribution of Turkish Dytiscidae.
