Stromatopelminae
The Stromatopelminae are a subfamily of tarantulas native to West Africa and part of Central Africa. The subfamily was first proposed by Günter Schmidt in 1993. Taxonomy The subfamily Stromatopelminae was first proposed by Günter Schmidt in 1993. The genera he included had been placed in the subfamily Eumenophorinae by Raven in 1985. Schmidt excluded them as they did not have the typical stridulating organ on the coxa and trochanter of the palps and legs which are present in Eumenophorinae. The subfamily was recovered as monophyletic in both a 2018 and a 2019 study, sister to the subfamily Harpactirinae. Genera Schmidt included two genera, both found in tropical West and Central Africa. Both genera were included in the 2019 study that found the subfamily to be monophyletic. *'' Heteroscodra'' Pocock, 1899 *'' Stromatopelma'' Karsch, 1881 Gallon in 2005 also placed the monotypic genus '' Encyocratella'' in the subfamily. The genus was not found to be part of the subfamily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarantula
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder ( Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Encyocratella
''Encyocratella'' is a monotypic genus of Tanzanian tarantulas (family Theraphosidae) containing the single species, ''Encyocratella olivacea'', also known as the Tanzanian black and olive baboon spider. It was first described by Embrik Strand in 1907, and is found in Tanzania. Description They are one of two tarantulas which females do not have a spermatheca, instead opting for oviducts and uterus externus. Its carapace is a golden color, with a golden opisthosoma with a black fishbone pattern and spotting. The femur is a deep black color, with the rest of the legs being golden as most of the rest of the body. Habitat They are found in the rainforests on the southern slopes of mount Meru in the Arusha Region. The average temperature is 19°C, with average yearly rainfall of 1400mm. They are usually found 2200 m above sea level, a region that is home to plants such as ''Juniperus'', ''Lobelia'' and ''Sedum''. Behavior They are arboreal in nature, but also show burrowi ...

Heteroscodra Maculata
''Heteroscodra maculata'' is an Old World species of tarantula which was first described in 1899 by Reginald Innes Pocock. This species native to West Africa and is found primarily in Togo and Ghana. This species has many common names, of which Togo starburst and ornamental baboon are most frequently encountered. Description These tarantulas can reach their full size after about 3 years. When fully grown, these species can reach leg-spans of up to . These spiders are characterized by their chalky white coloration with mottled black and brown markings. Notably, these tarantulas have very thick rear legs, leading many to believe that they are baboon spiders, however, they are not in the baboon spider subfamily of Harpactirinae. These tarantulas are an "old world species" originating from Asia and Europe. Being an "old world species", these tarantulas have highly potent venom, and are not recommended for handling. Behavior ''Heteroscodra maculata'' specimens are quite fast, defensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach t ... of freshwater fish.

Günter Schmidt (arachnologist)
Günter E. W. Schmidt (born 10 May 1926 in Lübeck; died 23 December 2016 in Deutsch Evern) was a German arachnologist and author of a standard German work on tarantulas, ''Die Vogelspinnen'' ("bird-eating spiders"). He has been described as one of the fathers of German arachnology. He studied biology and mostly worked in the pharmaceutical industry until his retirement.Obituary for Günther Schmidt by John Osmani In 1975, he graduated with a PhD thesis on the arachnid fauna of the Canary Islands . From 1986, his scientific work was concentrated mainly on tarantulas.

Eumenophorinae
The Eumenophorinae are a subfamily of tarantula spiders (family Theraphosidae). They are known from genera distributed across Sub-Saharan Africa, the south of the Arabian peninsula, Madagascar and its associated islands, and parts of India. Distribution At about 158-160 million years ago (Mya), Gondwana split up and the Indo-Madagascan plate drifted away from the rest of the super continent. At around 84-86 Mya, India split from Madagascar and drifted into Eurasia (66-55 Mya), to its current position. Therefore, all fauna in Gondwana (such as the Eumenophorinae) would be distributed on all three land masses. Characteristics The Eumenophorinae have stridulatory spike setae on the coxae of all legs, and a "comb" of stiffened setae on the palpal femur. In 2005, Richard Gallon described the monotypic genus '' Mascaraneus'', which lacks the stridulatory spike setae. Taxonomy The monophyly of the Eumenophorinae has been confirmed in a number of molecular phylogenetic Molecul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monophyly
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A ''polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harpactirinae
The Harpactirinae (commonly called baboon spiders) are a subfamily of tarantulas which are native to the continent of Africa. Like many Old World tarantulas, they have a relatively strong venom and can inflict a painful bite. Description Harpactirinae are ground-dwelling spiders which build silk-lined burrows, often under debris such as stones, using their fangs and chelicerae for digging. Habitats include savanna A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach th ... woodlands, grasslands, and dry scrublands. Systematics The following genera and species are present in the Harpactirinae. In addition, the genus '' Brachionopus'' (Pocock, 1897) has been suggested for placement in this subfamily, but its taxonomy is currently disputed. '' Augacephalus'' (Gallon, 2002) Type species ...
