Three new genus records of the spider fauna of Turkey (Araneae: Salticidae).

Salticidae is the most species rich family in Araneae and currently represented by 5570 species belonging to 591 genera in the world (Platnick 2013). In Europe, it is the third richest with around 400 nominal species (Helsdingen 2012), after the Palaearctic megadiverse Linyphiidae (Tanasevitch 2013) and Mediterranean diverse Gnaphosidae (Chatzaki 2008). This pattern is similar in Turkey by considering the available data, but current knowledge on spiders of Turkey may not represent the complete picture. Knowledge on Turkish Salticidae could be considered as in a preliminary state. Relevant literature is composed of studies presenting results of occasional surveys, in which complementarity have rarely been considered as a crucial component; and field surveys directed to address Salticidae are scarce. Consequently, new records are still easy to find during inventory studies.

Currently, the Salticidae is known by 99 species in 36 genera in Turkey (Bayram et al. 2013), which clearly is an underestimation. The majority of these species are broadly distributed, but mostly limited to the Palaearctic. Only one tenth of Turkish Salticidae show distributions beyond the Palaearctic, however; while around a quarter of the species have known distributions that mainly lie within the West Palaearctic or Mediterranean. Although not expected, there are also 5 endemics known from Turkey, all known only from close vicinities of their type locations. 2 of them were described many years ago and lack any further records, i.e., Euophrys fucata (Simon, 1868) and Habrocestum nigristernum Dalmas, 1920. The other three are recently described species, i.e., Heliophanus feltoni Logunov, 2009, Heliophanus konradthaleri Logunov, 2009 and Yllenus zaraensis Logunov, 2009. However by considering that members of Salticidae are usually widely distributed species, it is not certain whether these species are truly endemic or not, and further field surveys are necessary to address this problem.

In this paper, we present new records of 3 species of the spider fauna of Turkey, which also represent three new genus records that we encountered during recent field surveys from different regions of Turkey. These are Bianor albobimaculatus (Lucas, 1846), Dendryphantes rudis (Sundevall, 1833) and Hyllus insularis Metzner, 1999; which are all relatively widely distributed species. B. albobimaculatus have a known distribution from South Africa to Europe, Middle East, and Middle Asia (Logunov 2000; Proszynski 2003; Wesolowska & Van Harten 2007); and D. rudis has a wider distribution in Palaearctic (Almquist 2006), while H. insularis is known from a slightly narrower area from Greek islands to Iran (Metzner 1999, Logunov 2001).

MATERIALS AND METHODS

This study is based on the materials collected in 2011 and 2012 from different regions of Turkey. Specimens were collected by sweeping of herbaceus plants or by means of hand aspirators under stones and on plants. Identifications were made by use of Leica S8APO Stereomicroscope. Well known identification keys used for species identifications are those of Heimer & Nentwig (1991), Proszyni ski (2003) and Almquist (2006). Specimens were preserved in 70% ethanol. All measurements are given in millimeters. Abbreviations used in the text are as follows; Cx: coxa, Tr: trochanter, Fe: femur, Pa: patella, Ti: tibia, Mt: metatarsus, Ta: tarsus. Pictures were taken, using a Leica S8APO microscope by means of a Leica DC 160 camera. SEM microphotographs were made with a JEOL JSM-5600 instrument at the University of Kirikkale. Specimens are deposited in the collection of the Arachnological Museum of Kirikkale University (KUAM).

DISCUSSION

The new records presented here are not particularly surprising and actually the presence in Turkey of these 3 genera was within expectations, especially for the widely distributed B. albobimaculatus and D. rudis. The discovery of H. insularis is perhaps the most interesting, which previously had been known only from Lesbos Island, Greece and from several localities in Iran. By the discovery of this species in Turkey, an important gap in the distribution of H. insularis has been filled. Furthermore, the new locality record presented here is in very close proximity to the type locality, Lesbos Island near the Aegean coast of Turkey. Previously males had not been reported from anywhere close to the type locality, and so, the identity of the two separate populations from Greece and Iran is substantiated in a manner.

For the achievement of a better understanding of the Salticidae in Turkey and in the West Palaearctic area, further field surveys and taxonomic research are necessary to reveal currently unknown novel records and unknown species. It seems certain that the number of species will continue to increase rapidly in subsequent years with the continuing studies.
