Grammostola anthracina is a species of spider belonging to the family Theraphosidae (tarantulas). It is found in Uruguay, Paraguay, Brazil, and Argentina.[1]

Taxonomy

The species was first described in 1842 by Carl Ludwig Koch as Mygale anthracina. In 1850, he transferred it to the genus Eurypelma using the name Eurypelma anthracina.[2] (As the Greek word pelma is neuter,[3] the correct form of the species name in this combination is anthracinum, as used by Carl Friedrich Roewer in 1942, for example.[2]) In 2010, Norman Platnick synonymized Eurypelma with Avicularia, implicitly transferring the species to this genus. A re-examination of the holotype in 2011 suggested that it actually belonged to the genus Grammostola.[2]

Description

Grammostola anthracina is characterized by having an entirely brown body; females have long spermathecae with a rounded apex. The total length of a female's body is about 45 mm; the fourth (last) leg is longest at about 60 mm. The forward-facing side of the coxa of the first leg has stridulatory hairs. Urticating hairs of types III and IV are present on the upper surface of the abdomen. The form of the spermathecae, stridulatory hairs and urticating hairs are characteristic of the genus Grammostola.[2]
