Acanthoscurria

Genus Acanthoscurria Ausserer, 1871

Genus status. Synonymized genus Trasyphoberus Simon, 1903; by R. Raven in 1985.

Old name: Mygale Koch, 1842; Scurria Koch, 1842; Acanthopalpus Ausserer, 1871; Callyntropus Ausserer, 1875.

Type species - Acanthoscurria geniculata (C. L. Koch, 1841).

Representatives of genus Acanthoscurria differs from all other genuses of subfamily Theraphosinae by presence of subsferic form of receptacula semini of spermathecae of most species in combination with following features: 1) there`re several bunches of stridulating bristles on the lateral surface of palpal trochanter; 2) male with only one tibial spure; 3) there`re denominated nodule on the lateral surface of palpal tibia; 4) presence of type I urticating hairs.

This genus in present time is represented by 38 mainly large terrestrial species of tarantulas, inhabiting rainforests and pampases of South America.

Dwell in enough deep burrows, which, as a rule, dig by themselves.

For some species a maternal care by female tarantula have noted (Bucherl, 1952).

The average size of body is about 6-8 ёm, and can reach 23 ёm in legspan.

Not aggressive in general but rather nervious spiders. Regularly scratching urticating hairs, being disturbing. On available information a bite of species of the genus Acanthoscurria does not cause any harm for human.

Longlived tarantulas (15 years for species Acanthoscurria sternalis) has known. Also the maturation period in nature on available literary data known from 2 to 6 years at different species (Galiano (1984, 1992).

Keeping conditions. Very popular and unpretentious tarantulas. The majority of species can be kept in similar conditions under enough high humidity (70-85%) and temperature about 27-29Аб.

Most of species of this genus are very beautiful and desired object for collectors and amateurs. The most popular and widespread species in hobby all over the world, actively bred within last years - Acanthoscurria geniculata.

The majority of species of this genus can be recommended to keep for beginners.

Distribution. All representatives of Acanthoscurria inhabiting mainland areas of South America (Brazil). The only one species known from Antilles Islands.
