Three species of the spider genus Trachyzelotes Lohmander, 1944 have been recorded from the Crimea: T. pedestris (C.L. Koch, 1837), T. lyonneti (Audouin, 1827) and T. malkini Platnick et Murphy, 1984 (the last two species are new to Ukraine). The earlier Crimean records of T. barbatus (L. Koch, 1866) are misidentifications of T. malkini. The greatest activity and highest abundance of adult specimens for all Trachyzelotes species occurs in June. T. pedestris occurs in the submontane forest-steppe of the north macro-slope of the Crimean mountains; T. lyonneti and T. malkini occur in the saline semi-desert steppes and salt-marshes, but the latter is also recorded from the Quercus pubescens Juniperus excelsa Pistacia mutica forests on the southern coast.

We tested whether a specific mech- anism, an increase in non-native species with fragmentation, is responsible for this pattern. We found that both native and non-native taxa contributed to the pattern. Abundance of native spiders per pitfall trap sample increased significantly with decreasing fragment size (i.e. a negative density–area relationship) and abundance of non-natives increased significantly with increasing fragment age. The proportion of non-native individuals also increased significantly with age. One non-native species, Oecobius navus, comprised the majority of non-native individuals (82.2%) and a significant proportion of total individuals (25.1%).

  • Local and Landscape Correlates of Spider Activity Density and Species Richness in Urban Gardens
    Environmental Entomology Advance Access published July 6, 2015 COMMUNITY AND ECOSYSTEM ECOLOGY Local and Landscape Correlates of Spider Activity Density and Species Richness in Urban Gardens 1 2 2,3 MICHELLE D. OTOSHI, PETER BICHIER, AND STACY M. PHILPOTT Environ. Entomol. 1–9 (2015); DOI: 10.1093/ee/nvv098 ABSTRACT Urbanization is a major threat to arthropod biodiversity and abundance due to reduction and loss of suitable natural habitat. Green spaces and small-scale agricultural areas may provide habitat and resources for arthropods within densely developed cities. We studied spider activity density (a mea- sure of both abundance and degree of movement) and diversity in urban gardens in Santa Cruz, Santa Clara, and Monterey counties in central California, USA. We sampled for spiders with pitfall traps and sampled 38 local site characteristics for 5 mo in 19 garden sites to determine the relative importance of individual local factors. We also analyzed 16 landscape variables at 500-m and 1-km buffers surrounding each garden to determine the significance of landscape factors. We identified individuals from the most common families to species and identified individuals from other families to morphospecies. Species from the families Lycosidae and Gnaphosidae composed 81% of total adult spider individuals. Most of the significant factors that correlated with spider activity density and richness were local rather than landscape factors. Spider activity density and richness increased with mulch cover and flowering plant species, and decreased with bare soil. Thus, changes in local garden management have the potential to promote diversity of functionally important spiders in urban environments.

  • A CRITICAL REVIEW of the SPIDER FAMILY GNAPHOSIDAE in GREECE Maria Chatzaki
    Advances in Arachnology and Developmental Biology. UDC 595.44(495):575.17:577.2 Papers dedicated to Prof. Dr. Božidar Ćurčić. S. E. Makarov & R. N. Dimitrijević (Eds.) 2008. Inst. Zool., Belgrade; BAS, Sofia; Fac. Life Sci., Vienna; SASA, Belgrade & UNESCO MAB Serbia. Vienna — Belgrade — Sofia, Monographs, 12, 355-374. A CRITICAL REVIEW OF THE SPIDER FAMILY GNAPHOSIDAE IN GREECE Maria Chatzaki Department of Molecular Biology and Genetics, Democritus University of Thrace, Dragana, 68100 Alexandroupolis, Greece Abstract — In this paper an attempt is made to evaluate the current knowledge of gnaphosids in Greece from a zoogeographical and ecological point of view. Current species catalogs based on literature and on the author’s personal data provide a list of 124 species and 23 genera. These numbers are among the highest recorded in European countries and reveal the Mediterranean character of the family and its great diversity, especially in the area of the Eastern Mediterranean. Chorological analysis shows that along the vertical axis of the Greek Peninsula there is a decrease of European and Turano-European elements and an increase of Mediterranean and endemic elements. The representation of species with eastern origin is also more pronounced in the southern and eastern part of the country. This chorological vatiation along the main axis of Greece creates two main zoogeographical zones, a “north- continental” zone, which is mostly affected by the European arachnofauna, and a “south- continental/insular” zone, which is mainly characterized by its affinity to the East and its geographical isolation. The poor knowledge of the araneofauna throughout the whole area of the Eastern Mediterranean leads to an overestimation of local endemisms.

Hoffman Virginia Museum of Natural History Martinsville, Virginia 24112 ABSTRACT Forty-five species of ground spiders (gnaphosids) are documented as known members of the Virginia fauna, about 75% of an anticipated total of 60 to 65 species. Thirteen of the 45 species are listed for the state for the first time, some representing substantial range extensions, mostly from the south, but a capture of Nodocion rufothoracicus is the first record for that species east of the Mississippi River. One undescribed species, a minute form of Drassyllus, is known from Isle of Wight County. Twenty-four species are known from less than five counties, only six are known from more than 15; Zelotes duplex has been documented for 19 counties. Although many species are essentially statewide, at least at low elevations, 15 reflect lowland (austral) distributions, and five are chiefly or entirely restricted to higher elevations.

Over time, they have adapted to major changes in climate and fauna and have become widespread on all continents, living in almost any terrestrial habitat. It is known that approximately 50000 spider species belonging to 120 families worldwide, today. and this number increases almost every day due to new records are being given from many countries. Despite the high diversity of species, the number of cytogenetic studies on spiders is very scarce. Upto now, 868 species belonging to the 74 families were investigated by cytogenetically. Although more than a thousand species of spiders in Turkey, the Cytogenetic studies are insufficient. Thus, spiders are the most richest group of arachnids among arthropods. In this study cytogenetic studies on Keywords:spiders in Turkey were reviewed.

Critical analysis of existing spider species lists for Wisconsin, Michigan, Ohio. Indiana and Illinois reveals 900 species recorded from the five-state region (284 genera, 40 families). All non- native, Palearctic, or otherwise questionable species records were scrutinized, and their status is discussed. The most speciose families in the region are the Linyphiidae (almost 24% of species), Salticidae (10.3%), Theridiidae (8.9%), Lycosidae (8.8%), and Araneidae (7.7%). All sources used for spider species names and species records are unambiguously quoted. Spider species records are presented in tables allowing comparison of family composition among the states, and prediction of number of heretofore unrecorded species. Richness among states is analyzed and found to be dependent on varying degrees of sampling effort. As a new tool, a Spider Species Name Concordance Table allows tracking previously published spider species names to the currently valid name of every species record.

  • A Preliminary Checklist to the Spiders (Arachnida: Araneae) of Minnesota (U.S.A.) with Annotations
    A Preliminary Checklist to the Spiders (Arachnida: Araneae) of Minnesota (U.S.A.) with Annotations Chad J. Heins: Biology Department, Bethany Lutheran College, Mankato, Minnesota Assistant Professor of Biology Bethany Lutheran College 700 Luther Drive Mankato, MN 56001 Abstract This is a list of spider species for Minnesota (U.S.A.). It includes species that have been recorded in Minnesota as well as those which have ranges that suggest they are likely to be found in the state in the future. The checklist is a compilation of records from the literature, museums, and personal collection efforts by the author. Each species is annotated with a select reference or references and a comment if necessary. This list represents several new state records and expansions of several species’ known ranges. Key Terms: Minnesota, Araneae INTRODUCTION Spiders are an abundant component of terrestrial arthropod assemblages. Over 3,800 species of spiders have been documented in North America north of Mexico (Bradley 2013). They present interesting subjects for the study of behavior, taxonomy, and ecology and it has been suggested that they may serve as important ecological indicators (Clausen 1986; Churchill 1997). Their abundance, ease of capture, and limited expense to study make them ideal subjects for study at the undergraduate level and an interest in such applications sent the author in search of a list of Minnesota spiders. The only faunal list for Minnesota that could be located was limited to the family-level (Cutler 1976). Several states and provinces in North America have developed such spider faunal lists. In the Upper Midwest, such lists have been created for Michigan (Snider 1991), Illinois/Indiana (Beatty 2002), Wisconsin (Levi & Field 1954), and Manitoba (Benell-Aitchison & Dondale 1990).
