New Data on the Spider Fauna (Arachnida: Araneae) of Bulgaria

Abstract and Figures

New data on the distribution of spiders of the families Atypidae, Dictynidae, Mimetidae, Miturgidae, Mysmenidae, Oecobiidae, Pholcidae, Pisauridae, Synaphridae and Zodariidae are presented. The family Mysmenidae is newly recorded for Bulgaria, while Synaphridae is newly reported family for the Balkan Peninsula and for Bulgaria. The genus Oecobius is also new for the Bulgarian spider fauna. Illustrations contributing to the taxonomic characterisation of some species are provided. A total of ten species are newly recorded from different localities in the country. With the present report, the number of spider species recorded in Bulgaria is increasing up to 1047.

Introduction
The critical check-list of Bulgarian spiders
( &  2001) comprised 910 spe-
cies (of 42 families) and summarised 173 publica-
tions. Recently, due to the publication of 93 new
papers, the number of the spiders found on the ter-
ritory of Bulgaria increased to 1037 (of 43 families,
see  et al. 2002-2017). The present publi-
cation reports new faunistic data on the distribution
of spiders of the following ten families: Atypidae,
Dictynidae, Mimetidae, Miturgidae, Mysmenidae,
Oecobiidae, Pholcidae, Pisauridae, Synaphridae
and Zodariidae. Two families, Mysmenidae and
Synaphridae, are newly recorded for Bulgaria; the
latter is also new for the Balkan Peninsula. Oecobius
Lucas, 1846 is a new genus for the fauna of spiders
in Bulgaria. The aim of this paper is to report ten

Materials and Methods
The present faunistic list is based on the incorpora-
tion of some available unpublished records due to

leagues. The spider material was collected by hand,
with pitfall traps and with vacuum cleaner from dif-
ferent regions of the country (Fig. 1). Specimens
were examined and measured using Leica M205 C
and Wild M5A stereomicroscopes. Photos were tak-
en by Lumix digital camera attached to a Wild M5A
stereomicroscope. The specimens are preserved
in 70-80% ethanol and deposited in the Institute
of Biodiversity and Ecosystem Research (IBER–

Results
The examined material contained ten species (of ten
families), which are new for the Bulgarian fauna.

m a.s.l., 27.03.2017 (leg. M. Naumova; Fig. 1:
6). Synaphridae is a small family with three gen-
era and 13 species, distributed in Mediterranean
region (Spain, Croatia, Israel, Egypt), Ukraine,
Turkmenistan, the Canary Islands and Madagascar
(WSC 2017). Synaphris is the most speciose genus in
the family with its 11 species ( & 
2011), three of them occurring in Europe. Synaphris
lehtineni is described from Ukraine (Crimea) and
to date has been known only from there and from
Romania ( 2015). Morphologically, our mate-
rial corresponds well to the description of the spe-
cies, which is seen from the presented photos (Figs.

... (Hänggi et al. 1995), in old wastelands covered with bushes or grasslands and overgrowth of limestone karst plateaus (Gregorič & Kuntner 2009). Recently it was reported from Bulgaria (Naumova et al. 2017) with no habitat description. Adults were found in May and June, females until October (Svatoň et al. 2009). ...
... However, compared to neighbouring countries this number is rather moderate because the known number of species are in Hungary are 812 (Pfliegler et al. 2012, Nentwig et al. 2020, Albania 569 (Kůrka et al. 2020), and Montenegro 289 (Naumova et al. 2019). For Bulgaria (1046) (Naumova et al. 2017, Blagoev et al. 2018, Nentwig et al. 2020 and Romania (973) (Weiss & Petrișor 1999) the situation is somewhat better. If we bear in mind that Serbia is part of the Balkans, which is a European centre of biodiversity, it is reasonable to expect that future intensive research all over Serbia will increase this number significantly. ...

Good environmental management needs evidence-based conservation measures, and those measures need both faunistical and ecological information. Following this path, for the first time in Serbia, a faunistical research of spiders at Subotica Sandland was organised in 2014 as a base for ecological arguments in landscape management of the area. The spiders were collected at ten different habitats on sandy soil, in the period from 27th April till 30th October by pitfall trapping and sweep netting. A total of 16304 adult and 7246 juvenile individuals were captured, and 225 species from 27 families were determined. Thirty species represent new records for Serbia. Diversity and species compositions provided an insight into the quality of the habitats and the influence of the conservation and development measures that were already applied. The main endangerment factors are outlined. Conclusions and suggestions according to the analysis of the spider fauna, are mostly in correlation with those made earlier based on other groups of organisms. Within the scope of nature protection, wet and sandy meadows are prioritised over the woods. For future monitoring, two flagship and umbrella species are suggested: Argiope lobata (Pallas, 1772) for the sandy area and Dolomedes plantarius (Clerck, 1757) for the wetlands.
... In the last few years, the number of the Bulgarian spider species has increased significantly, both with newly described species (Deltshev et al. 2016;Dimitrov et al. 2017Dimitrov et al. , 2019Indzhov 2020;Lazarov & Dimitrov 2018;Naumova 2019) and species newly recorded for the country (Dimitrov & Naumova 2021;Naumova & Deltshev 2021;Naumova et al. 2017). Obviously, a part of the historical reports based on material that cannot be located (probably lost), should be approached very carefully and with scepticism of their identification, especially to species with known current range limited to small areas or located far from the Balkans. ...

This study is a part of an ongoing comprehensive inventory of Bulgarian spiders. A total of fifty spider species belonging to thirteen families are reported for the first time from Bulgaria. Four species are rejected from the Bulgarian spider checklist due to misidentification: Callilepis concolor Simon, 1914, Centromerus capucinus (Simon, 1884), Hoplopholcus labyrinthi (Kulczyński, 1903) and Mansuphantes prope fragilis (Thorell, 1875). Another four species (Drassodes villosus (Thorell, 1856), Entelecara flavipes (Blackwall, 1834), Lepthyphantes notabilis Kulczyński, 1887 and Singa semiatra L. Koch, 1867) are rejected after a new interpretation of the locations. Six species were omitted from the list of Bulgarian spiders as obviously doubtful records (Dysdera nicaeensis Thorell, 1873, Haplodrassus rufipes (Lucas, 1846), Harpactea hispana (Simon, 1882), Macaroeris cata (Blackwall, 1867), Nomisia celerrima (Simon, 1914) and Tenuiphantes monachus (Simon, 1884)). A new synonymy is proposed for Cyclosa strandjae Drensky, 1915 (= Cyclosa sierrae Simon, 1870 syn. nov.). In addition, new images with essential taxonomic value are provided for twenty-five species to facilitate their identification or to illustrate their intraspecific variability. To ensure correct identification, DNA barcoding was additionally used in some species.
... Anyway, the finding itself is a peculiar addition to the Bulgarian as well as to the European spider fauna, with the number of recorded Araneae species for Bulgaria reaching 1046 (Dimitrov et al. 2019, Lazarov & Dimitrov 2018, Naumova 2018, 2019, Naumova et al. 2017, 2019a, 2019b. ...

The following new Zodarion species are described from Italy: Zodarion pantaleonii Bosmans & Pantini spec. nov. and Z. pseudonigriceps Bosmans & Pantini spec. nov., both from Sardinia, Z. montesacrense Bosmans spec. nov. and Z. valentii Bosmans, Loverre & Addante spec. nov., both from Puglia, Z. valentii also occurs in Sicily. Zodarion sp., described from Greece in 2009, is the unknown female of Zodarion zorbaBosmans, 2009. Zodarion gracilitibiale Denis, 1934 is new for Italy. New records for 43 other European Zodarion species are presented.

A critical check list of Bulgarian spiders is presented, together with a comprehensive review of published data. Altogether 910 species based on 173 publications are listed, derived from a total of 7,222 records. Many changes in nomenclature have been made as a result of taxonomic revisions and the re-examination of existing collections. The following new synonyms are proposed: Linyphia phrygiana var. pirini Drensky, 1921 = Pityohyphantes phrygianus (C. L. Koch, 1836), Hogna (Tarentula) macedonica Drensky, l929 = Hogna radiata (Latreille, 1817), Prosthesima bitolensis Drensky, 1929 = Zelotes gracilis (Canestrini, 1868), Comaroma ressenensis Drensky, 1929 = Spermophora senoculata (Dugès, 1836), and Cyclosa strandjae Drensky, 1915 = Cyclosa conica (Pallas, 1772).

Three species of Synaphris occurring in the East Mediterranean - Synaphris orientalis Marusik & Lehtinen, 2003, Synaphris lehtineni Marusik, Gnelitsa & Kovblyuk, 2005 and Synaphris letourneuxi (Simon, 1884) - are surveyed; and a new species - Synaphris wunderlichisp. n. - is described from southern Israel on the basis of males. The new species differs from other East- Mediterranean congeners by its smaller size, a smaller lamella with fewer ridges, and a thick palpal femur. Comparative figures are provided for all species from the East Mediterranean.
