Mysmenidae
Mysmenidae is a spider family with about 180 described species in seventeen genera. The family is one of the least well known of the orb-weaving spiders because of their small size () and cryptic behaviour. These spiders are found in humid habitats such as among leaf litter and in caves. Distribution Species occur in the Americas, Africa, Asia, Europe, New Guinea and several islands. Genera , the World Spider Catalog accepts the following genera: *'' Brasilionata'' Wunderlich, 1995 — Brazil *'' Chanea'' Miller, Griswold & Yin, 2009 — China *'' Chimena'' Lin & Li, 2022 — China, Taiwan *'' Drungena'' Lin & S. Li, 2023 — China *'' Gaoligonga'' Miller, Griswold & Yin, 2009 — China, Vietnam *'' Isela'' Griswold, 1985 — Kenya, South Africa *'' Maymena'' Gertsch, 1960 — North America, Saint Vincent and the Grenadines, Central America, Peru *'' Mengmena'' Lin & Li, 2022 — China *'' Microdipoena'' Banks, 1895 — Africa, United States, Paraguay, Asia, Oceania *'' Mosu'' ...

Monotypic Araneomorphae Genera
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 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 system. ...
