Chromosomes of Theridiidae spiders (Entelegynae): Interspecific karyotype diversity in Argyrodes and diploid number intraspecific variability in Nesticodes rufipes
Theridiidae is a derived family within the Araneoidea clade. In contrast to closely related groups, the 2n(male) = 20+X(1) X (2) with acro/telocentric chromosomes is the most widespread karyotype among the theridiid spiders. In this work, the cytogenetic analysis of Argyrodes elevatus revealed original chromosome features different from those previously registered for Theridiidae, including the...
متن کاملPredation by Argyrodes ( Theridiidae ) on Solitary and Communal Spiders
Species of Argyrodes Simon (Theridiidae) are best known as kleptoparasites in the webs of other spiders, particularly in the tropics (Exline 1945; Exline and Levi 1962; Kaston 1965; Vollrath 1976, 1978, 1979). They live in or near the webs of their hosts and take prey from the host’s web. The methods used to take prey from the host vary for different species of Argyrodes and different host spec...

This study examined the endemic species of kleptoparasitic spiders in the genus Argyrodes from the Hawaiian Islands, a lineage previously known in the archipelago from only a single described species, Argyrodes hawaiiensis Simon. Here, two additional endemic species are described, A. ilipoepoe Rivera and Gillespie, n. sp., and A. laha Rivera and Gillespie, n. sp., with their biogeographical pat...
متن کاملStandardized spider (Arachnida, Araneae) inventory of Hankoniemi, Finland
Background During a field course on spider taxonomy and ecology at the University of Helsinki, the authors had the opportunity to sample four plots with a dual objective of both teaching on field methods, spider identification and behaviour and uncovering the spider diversity patterns found in the southern coastal forests of Hankoniemi, Finland. As an ultimate goal, this field course intended t...
متن کاملA Color-Mediated Mutualism between Two Arthropod Predators
The nature of interactions between animals varies depending on local selection pressure, trophic status of the participants, and evolutionary circumstances. Body coloration and other visual signals may also affect animal interactions. Game theory posits that if one species provides a "service" in exchange for a "goods," a mutualism may ensue. Mutualisms between two predators are rare because of...
