Spelopelma
''Hemirrhagus'' is a genus of Mexican tarantulas that was first described by Eugène Louis Simon in 1903. It is considered a senior synonym of ''Spelopelma''. Species of the genus ''Hemirrhagus'' are 5 to 12 cm long, usually black in colour, the urticating hairs on the opisthosoma are arranged in one dorsomedian patch, two dorsal paramedian patches, or two lateral patches. It is unique amongst the theraphosine genera because of the retrolateral coxal heels, the shape of the male palpal bulb, and the urticating hairs on the abdomen are reduced or completely missing. It is the only genus with epigean, troglophile and troglobitic species. Distribution Hemirrhagus tarantulas are all found in Mexico all of them are largely distributed from Tamaulipas in the north to Chiapas in the south, primarily in the mountainous regions of Sierra Madre Oriental, Eje Volcánico Transversal, Sierra Norte de Oaxaca, and Sierra Madre Sur. All of this tarantulas are found in individual caves, some sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theraphosidae
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,040 species have been identified, with 156 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.

Hemirrhagus Diablo
''Hemirrhagus diablo'' is a tarantula in the ''Hemirrhagus'' genus, it is found in Mexico, in several caves in the state of Morelos. It is named after a cave it is found in, "Cueva del diablo" which translated to "Devil's cave", diablo being devil. This tarantula was first described by Mendoza & Francke in 2018. Description ''Hemirrhagus diablo'' can be distinguished from most other ''Hemirrhagus'' tarantulas by having the urticating hairs arranged in two para median patches, which are brown in color. And by the shape of the male palpal bulb with a narrow base. The tarantula is dark brown in color with either some darker or whiter patches. Spiderlings are dark brown in color with some orange coloration in the para median patches. Habitat This tarantula is found in "Cueva del diablo", it is named as such after a legend. The cave is about 2 km long, in some of the deeper areas it is necessary to bring equipment to breath, as there is a lack of oxygen. In this cave several ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Hemirrhagus Billsteelei
''Hemirrhagus billsteelei'' is a tarantula in the ''Hemirrhagus'' genus of Mexican cave tarantulas. This tarantula is found in the Mexican state of Oaxaca. This tarantula was first described by Mendoza and Francke in 2018, and is named in honour of Bill Steele, because of his contributions of knowledge in Mexican caves. Description This tarantula is purely black in colour, with some grey tones. It has a slender body, as it is advantageous for traversing through crevices. It can be distinguished from all other Hemirrhagus species, with the exception of ''Hemirrhagus perezmiles'', in that it lacks tibial apophyses. It can be distinguished from the ''Hemirrhagus perezmiles'' as the shape of male palpal bulb is different. This tarantula can be found below the Cueva La Grieta entrance. Further inside the same cave ''Hemirrhagus grieta ''Hemirrhagus'' is a genus of Mexican tarantulas that was first described by Eugène Louis Simon in 1903.

The region promotes ecotourism to help preserve the biosphere with various enterprises offering cabins, camping, access and guides for hiking and mountain-biking trails, horseback riding, bird-watching, and cave exploration. It is also one of richest zones of biodiversity in Mexico, with 400 spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemirrhagus Akheronteus
''Hemirrhagus akheronteus'' is a tarantula which is part of the ''Hemirrhagus'' genus. It is found in Mexico, in the state of Queretaro, and is one of many Mexican cave tarantulas. It was first described by Mendoza and Francke in 2018. It is named after the latin word akheronteus, which means "pertaining to the stream of woe", referring to the acheron river in the infernal regions of Greek mythology. Characteristics The tarantula's color is a solid grey or even black, making it blend in well with rocks. This tarantula, although being from the New World, lacks urticating hairs. Males have thorn like hairs on their legs, which are attached to a socket and are mobile. Females lack these hairs. The specimens of this investigation were captured 400m from the cave entrance. Habitat They are found in the cave in the state of Queretaro in the Jalpan de Serra town, inside the cave "Cueva del Río Jalpan". This cave is found in the middle of the Sierra Gorda natural reserve.
