Cryptocteniza
''Cryptocteniza'' is a monotypic genus of North American mygalomorph spiders in the family Euctenizidae containing the single species, ''Cryptocteniza kawtak''. It was first described by Jason Bond, C. A. Hamilton and R. L. Godwin in 2020, and it has only been found in the United States.

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 ...

Jason Bond
Jason E. Bond is an American biologist working as a Professor of Entomology and the Schlinger Chair in Insect Systematics at the University of California, Davis. Education Bond attended Western Carolina University, earning a Bachelor of Science degree in biology in 1993. He earned a Master of Science in biology (1995) and Ph.D. in evolutionary systematics and genetics (1999) from Virginia Tech. Career Bond was a Professor of Biology, Chair of the Department of Biological Sciences and Director of the Auburn University Museum of Natural History at Auburn University. When he was an associate professor with the Department of Biology at East Carolina University, he discovered the spider '' Myrmekiaphila neilyoungi'' and numerous other species in the genus '' Aptostichus''. On August 6, 2008, Bond appeared on '' The Colbert Report'', where he named the spider '' Aptostichus stephencolberti'' after host Stephen Colbert Stephen Tyrone Colbert ( ; born May 13, 1964) is an Am ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3,000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to their creation of trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the " primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realised that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the ...
