Aphonopelma marxi is a species of spider in the family Theraphosidae (tarantulas), found in United States (Arizona, New Mexico, Colorado and Utah).[2] Aphonopelma behlei and A. vogelae, at one time considered separate species,[3] are now considered to be synonyms.[1][2]
Aphonopelma marxi is generally dark brown to black in color, very hairy, with some orange to red hairs on the abdomen. The mature male's carapace ranges from 8.3 to 10.5 mm (0.33 to 0.41 in) long, the mature female being larger, with a carapace from 13.5 to 15.3 mm (0.53 to 0.60 in) long.[2] The total body length of a female, including the chelicerae, is around 35 mm (1.4 in).[3] A. marxi can be distinguished from other species of the genus living in the same places by its dark color, overall hairy appearance, size and habitat. In males, the ratio of the length of the femur of the first leg to the length of the metatarsus of the same leg is greater than 1.69, whereas in similar species the ratio is smaller. In females, the ratio of the length of the femur of the first leg to the length of metatarsus of the third leg is greater than 1.76, being smaller in similar species.[2]
The species was first described by Eugène Simon in 1891 as Eurypelma marxi.[1] The original type specimen on which the species was described has been lost; in 1997, T. R. Prentice designated a neotype.[2] Placement in the genus Aphonopelma was first made by Andrew M. Smith in 1995.[3][2] Smith also recognized two species, A. behlei and A. vogelae, that in analyses performed by Hamilton et al. in 2016 were not distinguished from A. marxi on either morphological or molecular grounds, and so were treated as junior synonyms. Aphonopelma marxi belongs to the "Marxi species group" – a group of mainly black species, often found in high-elevation habitats. Other species of the group include A. catalina, A. chiricahua, A. madera, A. peloncillo and A. vorhiesi.[2]
Aphonopelma marxi is widely distributed in areas of higher elevation in the "Four Corners" region of northern Arizona, northwestern New Mexico, southwestern Colorado, and southeastern Utah. It is found in a variety of habitats, including mixed conifer forests and sagebrush steppe. The species is described as "very common" in these areas, but is difficult to find as it normally remains in its hidden burrow. The burrows of all the Marxi species group have been described as "incredibly difficult to find".[2]

Aphonopelma marxi es una especie de araña migalomorfa del género Aphonopelma, familia Theraphosidae.[1] Fue descrita científicamente por Simon en 1891.[1]
Habita en los Estados Unidos.[1]
Es generalmente de color marrón oscuro a negro, muy peludo, con algunos pelos de color naranja a rojo en el abdomen. El caparazón del macho maduro varía de 8,3 a 10,5 mm (0,33 a 0,41 pulgadas) de largo, siendo la hembra madura más grande, con un caparazón de 13,5 a 15,3 mm (0,53 a 0,60 pulgadas) de largo.[2] La longitud total del cuerpo de una hembra, incluidos los quelíceros, es de unos 35 mm (1,4 pulgadas).[3] A. marxi se puede distinguir de otras especies del género que viven en los mismos lugares por su color oscuro, apariencia peluda en general, tamaño y hábitat. En los machos, la relación entre la longitud del fémur de la primera pata y la longitud del metatarso de la misma pata es superior a 1,69, mientras que en especies similares la relación es menor. En las hembras, la relación entre la longitud del fémur de la primera pata y la longitud del metatarso de la tercera pata es superior a 1,76, siendo menor en especies similares.[2]
Aphonopelma marxi está ampliamente distribuida en áreas de mayor elevación en la región de las "Cuatro Esquinas" del norte de Arizona, noroeste de Nuevo México, suroeste de Colorado y sureste de Utah. Se encuentra en una variedad de hábitats, incluidos bosques mixtos de coníferas y estepas de artemisa. La especie se describe como "muy común" en estas áreas, pero es difícil de encontrar ya que normalmente permanece en su madriguera oculta. Las madrigueras de todo el grupo de especies de Marxi se han descrito como "increíblemente difíciles de encontrar".[2]
