Acanthoscurria

Species	Picture	Common Name	Native to...	Adult Size	Arboreal / Terrestrial	Comments
Acanthoscurria atrox		Matto Grosso Redrump	Brazil		Terrestrial	Care is similar to that of other Acanthoscurria sp.  Give plenty of substrate, a hide, and a water dish.  This species may use a hide or it may build a burrow - not often directly out in the open.
Acanthoscurria brocklehursti			Brazil	7-8"	Terrestrial	Care is pretty much identical to that of A. geniculata.  This species also tends to be nervous and will readily flick hairs.  Looks almost identical to A. geniculata - only very subtle differences.
Acanthoscurria chacoana		Bolivian Salmon	Bolivia	6-7"	Terrestrial	Care is similar to that of other Acanthoscurria sp.  Give plenty of substrate, a hide, and a water dish.  This species may use a hide or it may build a burrow - not often directly out in the open.
Acanthoscurria geniculata		Giant White Knee	Brazil	7-8"	Terrestrial	Will do well in a typical setup with hide, water dish, and substrate.  Humidity and temperature is not typically a concern.  This species can be nervous/skittish and will readily kick hairs.  However, they are very hardy and do well in captivity.
Acanthoscurria insubtilis			Bolivia	5-6"	Terrestrial	Care is similar to that of other Acanthoscurria sp.  Give plenty of substrate, a hide, and a water dish.  This species may use a hide or it may build a burrow - not often directly out in the open.
Acanthoscurria juruenicola		Matto Grosso Salmon	Brazil		Terrestrial	Not very popular in US collections.  This species does well as spiderlings in moist substrate and care should be given not to let it dry out.

Aphonopelma

Aphonopelma spp. are known for their very slow growth rates, many taking 5 or more years to reach sexual maturity!  However, they are generally quite long-lived (females reported living in excess of 30 years!) and are typically very hardy in captivity.  Most species are typically docile, although some (such as A. seemani) are skittish and shouldn't be handled.  Humidity isn't a big concern, as many from this genus hail from arid regions of the USA and Mexico.  A water dish will typically supply all the necessary humidity.

Species	Picture	Common Name	Native to...	Adult Size	Arboreal / Terrestrial	Comments
Aphonopelma anax		Texas Tan	USA	5-6"	Terrestrial	Great for beginners.  Docile.  Basic housing requirements - substrate, hide, and water dish.  Does well at room temperature.
Aphonopelma bicoloratum			Mexico	5-6"	Terrestrial	Another native US species with remarkable coloration.  Very simple setup required - basic hide, water dish, and dry substrate.  No special heating or humidity requirements.  Adults of this species are typically somewhat expensive and not often seen for sale.
Aphonopelma chalcodes		Desert Blonde	Mexico / USA	5-6"	Terrestrial	Great for beginners.  This US-native species is typically docile and does well in a basic setup with a hide, water dish, and dry substrate.  No special heating or humidity requirements.
Aphonopelma crinirufum		Costa Rican Bluefront	Costa Rica		Terrestrial	Average-growing Aphonopelma sp. from Costa Rica.  This species does seem to do well with a bit higher humidity - very similar to A. seemani.  Typical terrestrial setup with hide and water dish.
Aphonopelma hentzi		Oklahoma Brown	USA	5-6"	Terrestrial	Great for beginners.  Docile.  Basic housing requirements - substrate, hide, and water dish.  Does well at room temperature.  Very common US species that can be found from Texas to Missouri.
Aphonopelma moderatum		Rio Grande Gold	USA	5-6"	Terrestrial	Great for beginners.  Docile.  Basic housing requirements - substrate, hide, and water dish.  Does well at room temperature with no special humidity requirements.
Aphonopelma seemani		Costa Rican Zebra	Costa Rica, Honduras, El Salvador, Nicaragua	5-6"	Terrestrial	Will burrow in captivity.  6" or more of substrate should be provided.  Skittish / nervous and not recommend for handling.  Does well with higher humidity.  Mating is a bit difficult in captivity, as the females are not always receptive and males are typically very nervous/skittish.

Avicularia

The Avicularia genus - the classic beginner's arboreal!  These fascinating tree-dwellers from South America are generally docile, although they are known for being fast and jumpy.  It is hard to find a spider more beautiful than A. versicolor, which has quickly become a hobby classic.  These spiders generally do well with higher humidity and good ventilation, which can lead to mistakes for many starting out in the hobby.  There is still much to be known about the Avicularia genus, and there are many species that are incorrectly labeled and are being cross-bred in the hobby due to such mistakes.

There are currently four Avicularia species in the hobby that can be easily identified - A. laeta, A. minatrix, A. purpurea, and A. versicolor.  To learn more about the Avicularia genus, I recommend reading this online article by Ray Gabriel.

Metriopelma

The genus Metriopelma is a dwarf genus that hails from South America. Members of this genus often reach sexual maturity within one or two years. Many of the known species of Metriopelma are found primarily in Venezuela and surrounding countries. Most Metriopelma spp. are burrowers, particularly when young. These spiders generally do best with higher humidity and when given the chance to create their often extensive burrows.
