''Aphonopelma'' is a genus of tarantulas native to the

Americas The Americas, which are sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with th ...

. It includes nearly all the North American tarantula species north of Mexico and a considerable percentage of the tarantula species that range into Central America. Most are fairly large tarantulas with leg spans of 6 in (16 cm) or more. Like most New World tarantulas, all species of ''Aphonopelma'' have urticating hairs. Despite their fearsome appearance, these tarantulas are not harmful to humans and some species are popular in the pet trade. With about 90 species described so far, ''Aphonopelma'' comprises about 10% of the total number of described tarantula species. However, their taxonomy is poorly understood and species are difficult to tell apart, especially those that are brown or black without other pattern. Therefore, the actual number of species is unknown, with more species likely to be identified in the near future. In captivity, they are usually fed

s; in the wild, they eat most insects, including crickets, grasshoppers, cockroaches, mantises, and beetles.

Taxonomy

The genus has a complicated taxonomic history. It was erected in 1901 by Reginald I. Pocock, when he split up ''Eurypelma'' (now '' Avicularia''), with the type species '' Eurypelma seemanni''. Pocock also separated off the genus ''Dugesiella''. Two more new genera were later distinguished from ''Aphonopelma'': ''Delopelma'' by Alexander Petrunkevitch in 1939 and ''Chaunopelma'' by Joseph C. Chamberlin in 1940. In 1985, Robert J. Raven reviewed mygalomorph genera and considered the differences among all these genera to be insignificant. He synonymized them under the name ''Rhechostica'', which had been published by

Eugène Simon Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4, ...

in 1991 agreed to give ''Aphonopelma'' precedence over ''Rhechostica''. In 1995, Smith erected the genus ''Apachepelma'' for the species '' A. paloma''; in 1997, Prentice transferred it back to ''Aphonopelma''. California ebony tarantula

Phylogeny

Molecular phylogenetic studies suggest that the genus is not

monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic gro ...

. Two groups of species are apparent: one from Central America, including the type species ''A. seemanni'' from Costa Rica, and another made up of species found in the United States. The relationship between the two groups and the genus '' Sericopelma'' is shown in the cladogram below. With further research, a new genus may be needed for the American group of species.

Species

, the World Spider Catalog accepted 59 species. A monograph of the genus within the United States, published in 2016, made some major revisions. Only 15 of the original 55 U.S. species were fully accepted, 33 were reduced to
