Myrmekiaphila
''Myrmekiaphila'' is a genus of North American mygalomorph trapdoor spiders in the family Euctenizidae, and was first described by G. F. Atkinson in 1886. All described species are endemic to the southeastern United States. Originally placed with the Ctenizidae, it was moved to the wafer trapdoor spiders in 1985, then to the Euctenizidae in 2012. ''Myrmekiaphila'' appears as the sister group to all southwestern Euctenizidae with the exception of '' Apomastus'', which in turn is the sister group to all euctenizines. ''M. flavipes'' was transferred from ''Aptostichus'' in 2007. Description The known species of this genus resemble each other in appearance and behavior. The carapace is long and wide. Females are uniformly colored, with some dusky stripes on the dorsum of the abdomen. Colors range from yellowish red to dark reddish brown. The palpal tibia of the males are modified in a way that distinguishes them from other mygalomorph spiders of North America. The first legs in ...

Euctenizidae
The Euctenizidae (formerly Cyrtaucheniidae subfamily Euctenizinae) are a family of mygalomorph spiders. They are now considered to be more closely related to Idiopidae. Etymology The name comes from the Greek prefix (''eu-''), meaning "valuable" or "good", which had been thought that the family Ctenizidae possess these traits.Bond, J. E., B. E. Hendrixson, C. A. Hamilton & M. Hedin. (Bond et al., 2012b) - ''A reconsideration of the classification of the spider infraorder Mygalomorphae (Arachnida: Araneae) based on three nuclear genes and morphology'' Biology Many, but not all, make wafer-like doors to their burrows, while others build the cork-like doors found commonly in the true trapdoor spiders. The biology of nearly all of the species is poorly known. Distribution The family occurs almost exclusively in the United States and Mexico. Common U.S. genera include '' Myrmekiaphila'', '' Aptostichus'' and '' Promyrmekiaphila''. Genera , the World Spider Catalog accept ...

Ctenizidae
Ctenizidae ( ) is a small family of mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation, and silk. They may be called trapdoor spiders, as are other, similar species, such as those of the families Liphistiidae, Barychelidae, and Cyrtaucheniidae, and some species in the Idiopidae and Nemesiidae. The name comes from the distinctive behavior of the spiders to construct trapdoors, and ambush prey from beneath them. In 2018, the family Halonoproctidae was split off from the Ctenizidae. A further genus, '' Stasimopus'', was split off into its own family, Stasimopidae, in 2020. The family currently consists of two genera and five species. Etymology The name derives from Greek ''ktenizein'', meaning "combing" or "cleaning", referring to their behaviour of cleaning continuously, and the suffix "-idae", which designates belonging to a family. Taxonomy The family Ctenizidae was first described by Thorell in 1887, being based on the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
