Expertise in biodiversity research (taxonomy, faunistics, conservation with taxonomic background) appears to decline worldwide. While the “taxonomic impediment” is discussed extensively in the literature, much fewer papers focus on the identification crisis, i.e., the decreasing number of experts who can identify species, and the decline of species...

Local microgeographic sites subdivided by sharp ecological and climatic contrasts are important platforms for measuring biodiversity patterns and inferring the possible effect of climatic and ecological variables on species distributions and habitat use. Here, we report results from 24 months (September 2019–August 2021) of continuous pitfall trapp...

Species of the genus Eresus Walckenaer, 1805 – commonly known as ladybird spiders – are well characterized by the males' distinct abdominal pattern. The bright red background with four to six dots is a rather uniform pattern within the genus with only a surprisingly growing number exceptions. We used both molecular and morphological data to sort ou...

The species Xysticus lendli is known only from its original description of a single male and one doubtful record so far. Here, we illustrate and redescribe the species based on 34 specimens in total and describe its female for the first time. We illustrated the male palp via compound micrographs and scanning electron micrographs. We generated a DNA...

A hasadékpókok (Filistatidae család) a Mediterráneum jellegzetes és elterjedt képviselői. Eleddig egyetlen magyar előfordulásukról volt tudomásunk, 1985-ben PEKKA LEHTINEN három példányt gyűjtött (az adatok közlésére 2019-ben került sor), melyek a Turkui Egyetem gyűjteményében találhatóak. A családnak további magyarországi észlelései a várakozások...

The dysderid spider genus Dysderella Dunin, 1992 is surveyed. The genus currently comprises two species: D. caspica (Dunin, 1990) from Azerbaijan and North Caucasus and D. transcaspica (Dunin & Fet, 1985) from Turkmenistan and north-eastern Iran. Herein, D. elburzica sp. nov. is described based on male specimens collected in Tehran Province, northe...

The gnaphosid spider genus Sernokorba Kamura, 1992 is reviewed. While Sernokorba pallidipatellis (Bösenberg and Strand 1906) and Sernokorba fanjing Song, Zhu & Zhang, 2004, occur in the Far East and the Japanese archipelago, Sernokorba tescorum (Simon, 1914) is known from Europe. We here describe a fourth species, Sernokorba betyar sp. nov. (male a...

The eresid spider genus Loureedia (Miller et al., 2012) was described a decade ago, despite its type species being described in the mid-19th century, which illuminates the difficulties in obtaining specimens. The genus was initially described as monotypic. Ever since, four other species have been assigned to Loureedia, including three newly discove...

The taxonomy of the Iranian species of the dysderid spider genus Dysdera Latreille, 1804 is revised. Currently, the only species of this genus known from Iran is D. pococki Dunin, 1985, albeit on the basis of a doubtful record. The following 14 species are described as new to science in this paper: D. achaemenes sp. nov. (♀; Fars), D. bakhtiari sp....

Thiratoscirtina is an African endemic subtribe of aelurilline jumping spiders. Among the 18 genera belonging here, the genus Pochyta Simon, 1901 and its ten currently recognized species is yet to be revised, and the described species have been not studied from a taxonomical perspective. We examined all the species thought to belong here based on th...

Two new species of the currently monotypic thiratoscirtine genera Ajaraneola Wesołowska & Russell-Smith, 2011 and Nimbarus Rollard & Wesołowska, 2002 are described from Uganda and Cameroon: Ajaraneola pajakwandy sp. nov. (male) and Nimbarus nimbus sp. nov. (male), respectively. With the new species, previous diagnoses of the genera are re-evaluated...

New taxonomic data are provided on the ladybird spider genus Eresus Walckenaer, 1805 in Turkey and Iran. Eresus adaleari Zamani & Szűts, sp. n. is described as a new species, on the basis of a single male specimen collected in Semnan Province, northeastern Iran, and Eresus lavrosiae Mcheidze, 1997, previously known solely from the original descript...

A previously unreported radiation of myrmarachnine jumping spiders from New Guinea is described, which, although having few known species, is remarkably diverse in body forms. This clade is the new subtribe Levieina, represented by seven new species in three new genera. Within Levieagen. n. are three new species, L.herbertisp. n., L.lornaesp. n., a...

Aim As a continental island, much of the biota of New Zealand was initially thought to have been shaped by vicariance. Recent studies, however, have highlighted the role of dispersal, with some even suggesting that the entire biota is the product of dispersal events following emergence of the islands. This study focuses on the interplay between dis...

Spatial variation in biodiversity is one of the key pieces of information for the delimitation and prioritisation of protected areas. This information is especially important when the protected area includes different climatic and habitat conditions and communities, such as those along elevational gradients. Here we test whether the megadiverse com...

In this paper we propose Trebacosa brunhesi Villepoux, 2007 as a junior synonym of Trebacosa europaea Szinetár & Kan-csal, 2007 based on the examination of specimens from all the localities from where those species are known. Illustration of the type species of the genus, Trebacosa marxi (Stone, 1890) and specimens from all known localities of T. e...

We present a phylogenetic analysis of spiders using a dataset of 932 spider species, representing 115 families (only the family Synaphridae is unrepresented), 700 known genera, and additional representatives of 26 unidentified or undescribed genera. Eleven genera of the orders Amblypygi, Palpigradi, Schizomida and Uropygi are included as outgroups....

The relationships of the unusual salticid spider Depreissia from central Africa and Borneo have been difficult to resolve, obscured by its highly modified ant-like body. Phylogenetic analysis of the gene 28S strongly supports its placement outside the major clade Salticinae and within the clade of cocalodines, spartaeines and lapsiines, with weaker...

The family Eresidae C. L. Koch, 1850 is reviewed at the genus level. The family comprises nine genera including one new genus. They are: Adonea Simon, 1873, Dorceus C. L.

Based on a survey of a wide variety of oonopid genera and outgroups, we hypothesize new synapomorphies uniting the Oonopidae (minus the South African genus Calculus Purcell, which is transferred to the Orsolobidae). The groundplan of the tarsal organ in Oonopidae is hypothe sized to be an exposed organ with a distinctive, longitudinal ridge origina...

The first lowland species of the alpine genus Parasyrisca, Parasyrisca arrabonica Szinetár & Eichardt, sp. n., is described from the sandy grasslands of Hungary. The genus was hitherto known only from Western Europe (Pyrenees and Western Alps) and Eastern Europe (Crimea), and although records from Slovenia and Romania were known, these are listed i...

The evolutionary diversification of spiders is attributed to spectacular innovations in silk. Spiders are unique in synthesizing many different kinds of silk, and using silk for a variety of ecological functions throughout their lives, particularly to make prey-catching webs. Here, we construct a broad higher-level phylogeny of spiders combining mo...

Intensive fieldwork has been undertaken in Portugal in order to develop a standardized and optimized sampling protocol for Mediterranean spiders. The present study had the objectives of testing the use of semi-quantitative sampling for obtaining an exhaustive species richness assessment of spiders and testing the effects of day, time of day, collec...

Declines of West-European farmland biodiversity have been associated with intensive agricultural practices, Central and Eastern European grasslands still harbour a diverse and unique arthropod community. However, our understanding of the effects of farmland management both at local and landscape levels is rather limited there. A paired field approa...

A thorough inventory of a Mediterranean oak forest spider fauna carried out during 2 weeks is presented.
