TAXONOMIC AND MOLECULAR STUDY OF THE WIDOW SPIDER GENUS LATRODECTUS WALCKENAER, 1805 (ARANEAE: THERIDIIDAE) IN IRAQ

TLDR
This study characterizes the first phylogenetic relationship to the Latrodectus genus in Iraq and is made by sequence of the partial mt DNA-COI gene.

North American widow spiders (Araneae: Theridiidae)

TLDR
This work reviews and synthesizes published information on the five North American Latrodectus species, focusing on distribution, ecology, anatomy, physiology, reproduction, ontogeny, behaviour, web structure, silk, venom, genetics, and phylogeny.

α-Latrotoxin Genes are Highly Divergent Between Species of Widow Spiders (Genus Latrodectus)

TLDR
The study presented here characterizes the genetic composition of α-latrotoxin from two additional species, the brown widow and the southern black widow, and compares it to that of a second gene, cytochrome oxidase I, which is not associated with Latrodectus venom.

Susceptibility of Latrodectus geometricus (Araneae: Theridiidae) to a Mucor Strain Discovered in North Central Florida, USA

TLDR
Subsequent bioassay trials supported with 83% mortality that this novel strain of M. fragilis does infect and kill L. geometricus.

Phylogeography of the ‘cosmopolitan’ orb-weaver Argiope trifasciata (Araneae: Araneidae)

TLDR
The results strongly suggest that A. trifasciata as currently defined is not a single species but a complex of cryptic species with more limited geographical ranges, which provides the basis for future investigation of morphological and/or ecological disparity between the populations that are likely to represent species.

Species status and conservation issues of New Zealand’s endemic Latrodectus spider species (Araneae : Theridiidae)

TLDR
The species status of the Latrodectus spiders of New Zealand was assessed using molecular and morphological methods and with cross-breeding experiments and it is concluded that L. atritus is a junior synonym of L. katipo.

Widow spiders in the New World: a review on Latrodectus Walckenaer, 1805 (Theridiidae) and latrodectism in the Americas

TLDR
This review addresses widow spiders’ taxonomy; geographical distribution and epidemiology; symptoms and treatments of envenomation (latrodectism); venom collection, experimental studies, proteome and transcriptome; and biotechnological studies on these Latrodectus spp.

Redescription and generic placement of the spider Cryptachaea gigantipes (Keyserling, 1890) (Araneae: Theridiidae) and notes on related synanthropic species in Australasia.

TLDR
The idea of a recent and limited initial introduction is supported by cytochrome c oxidase subunit 1 (COI) sequences, which are extremely homogeneous from New Zealand specimens compared to those from Australia.

A new forest dwelling button spider from South Africa (Araneae, Theridiidae, Latrodectus).

The medically important spider genus Latrodectus Walckenaer 1805, commonly referred to as "button spiders" in South Africa, is represented by six species in the country. Using morphology and the COI

A New Species of Widow Spider (Genus Latrodectus)From Southern Africa (Araneae: Theridiidae)

TLDR
A new species of widow spiders is described from Rhodesia%; the first sibling species o.f the cosmopolitan Brown widow (L. geometricus) is described and the two species seem to occur’ together.

Radiation of the Spider Genus Dysdera (Araneae, Dysderidae) in the Canary Islands: Cladistic Assessment Based on Multiple Data Sets

TLDR
The present study provides a phylogenetic framework for an exceptional case of insular species radiation, an essential tool for unraveling the factors that have promoted this amazing diversification of spider genus Dysdera.

Revision of the Widow‐spider genus Latrodectus (Araneae: Theridiidae) in Israel

The six species of Widow-spiders (Latrodectus) found in Israel are revised. Three of them are reported for the first time from this region. The Mediterranean L.tredecimguttatus is maintained as a

Phylogenetic relationships of Central European wolf spiders (Araneae: lycosidae) inferred from 12S ribosomal DNA sequences.

TLDR
Among the three different styles of predation found in the Lycosids, tube builders appear to be the most ancestral from which burrow dwellers descended and from which two groups of vagrant hunters evolved in parallel.

Molecular insights into species phylogeny, biogeography, and morphological stasis in the ancient spider genus Hypochilus (Araneae: Hypochilidae).

  • 2001
TLDR
Although the molecular data provide limited resolution of root placement within Hypochilus, most analyses are at least consistent with morphology-supported montane relationships of (Rockies (California, Appalachian), and these extreme divergences are most consistent with morphological stasis at the species level.

PARAPHYLY OF THE ENOPLOGNATHA OVATA GROUP (ARANEAE, THERIDIIDAE) BASED ON DNA SEQUENCES

TLDR
The results indicate that the E. ovata clade is not monophyletic, and the genus Enoplognatha Pavesi 1880 is generally one of the more primitive groups in the Theridiidae.

North American Widow Spiders of the Latrodectus Curacaviensis Group(Araneae: Theridiidae)

TLDR
Field and laboratory work in Curacao, Lesser Antilles, and in Florida, as well as additional specimens, have provided many more data on the species called L. curacaviensis, which was described in a previous study of Latrodectus.

An Adaptive Radiation of Hawaiian Thomisidae: Biogeographic and Genetic Evidence

TLDR
A phylogenetic hypothesis was constructed based on genetic distances between the Hawaiian thomisids and various outgroups using a 450 bp region of the mitochondrial cytochrome oxidase I (COI) gene to test for close genetic relationships, and results support the existence of a Hawaiian Thomisid adaptive radiation.

The behavioural ecology of Latrodectus hasselti (Thorell), the Australian redback spider (Araneae : Theridiidae) : a review

TLDR
It is concluded that L. hasseIti would have been able to persist in outback Australia for millions of years, with ItS mtraspeClfJc predatory habits aiding subsistence and the evolution of sexual cannibalism providing a way of coping with infrequent meeting and matmg opportunities.
