	Metaltella Simoni ''Metaltella simoni'' is a species of spider, Indigenous (ecology), native to South America (Brazil, Uruguay and Argentina), and introduced into the United States and Canada. image:M. simoni male left palp.jpg, Left palp of male, ventral view Description Females are about 8 to 9 mm long, males about 7 to 8.5 mm long. Both sexes are brown, with some darker parts, such as of the front of the carapace (the upper surface of the cephalothorax), the ends of the legs and the chelicerae. The abdomen (opisthosoma) is mottled grey or grey–black, with indistinct paler chevrons towards the rear. Males have an orange-yellow area towards the back of the carapace, darkening to brown at the front. The lateral eyes of both sexes are larger than the median eyes. Taxonomy ''Metaltella simoni'' was first described as ''Amaurobius simoni'' by Eugen von Keyserling in 1878. It was transferred to the genus ''Metaltella'' by Pekka T. Lehtinen in 1967.

	Desidae Desidae is a family of spiders, some of which are known as intertidal spiders. The family is named for the genus '' Desis'', members of which live in a very unusual location — between the tides. The family has been reevaluated in recent years and now includes inland genera and species as well, such as '' Badumna'' and '' Phryganoporus''. In 2017, the family Amphinectidae was merged into Desidae. The family Toxopidae has been separated off. Those intertidal spiders that are truly marine commonly live in barnacle shells, which they seal up with silk; this allows them to maintain an air bubble during high tide. They emerge at night to feed on various small arthropods that live in the intertidal zone. Distribution As now circumscribed, the family Desidae is mainly found in South America and Australasia, with some species reaching north to Malaysia. '' Metaltella simoni'' has been introduced in a large part of the Southern United States (records exist from California, Louisiana, Mi ...

picture info	Species In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google]
