Chromosome mapping of dragline silk genes in the genomes of widow spiders (araneae, theridiidae) [PDF]
, 2010 With its incredible strength and toughness, spider dragline silk is widely lauded for its impressive material properties. Dragline silk is composed of two structural proteins, MaSp1 and MaSp2, which are encoded by members of the spidroin gene family ...

Contribution to the distribution of spiders with significant medical importance (Araneae: Loxosceles and Latrodectus) in Iran, with a new record for the country [PDF]
Iranian Journal of Animal Biosystematics, 2014 A faunistic review is given on the Iranian medically important spiders of two genera Loxosceles and Latrodectus. Latrodectus cinctus Blackwall, 1865 is reported for the first time from Iran (and for the second time from Asia) and is replaced with the ...

The Northern Widow Spider, Latrodectus Variolus (Araneae: Theridiiae), in Michigan [PDF]
, 2017 Until recently the species of widow spider occurring in Michigan was considered a variant of the black widow, Latrodectus mactans (Fabricius). Levi (1959) summarized and revised the worldwide genus Latrodectus, placing the southern areas of Illinois ...

Envenomation caused by Latrodectus geometricus in São Paulo state, Brazil: a case report
Journal of Venomous Animals and Toxins including Tropical Diseases, 2009 Widow spiders (Latrodectus spp.), also known as "black widows", have a worldwide distribution and can cause latrodectism. To the best of our knowledge, in Brazil, only one case of Latrodectus geometricus (Koch, 1841) envenomation in a human has been ...

Latrodectus Envenomation in Greece [PDF]
The Permanente Journal, 2014 During the summer period 2011-2012, seven widow spider bites in Greece were reported to the Hellenic Center for Disease Control and Prevention. Widow spiders (in the genus Latrodectus) are found all over the world, including Europe, Asia, Africa, Australia, and the US. Alpha-latrotoxin (main mammalian toxin) causes the toxic effects observed in humans.
