Contribution to the genus Camerobia Southcott (Acariformes: Camerobiidae): description of C. exnuda sp. n. from Türkiye

The genus Camerobia Southcott (Acariformes: Camerobiidae) is a small but morphologically distinctive group within the superfamily Raphignathoidea. It currently comprises six described species worldwide, with one species—C. turcica Koç and Kara—from Türkiye. In this study, another species, C. exnuda sp. n., is described from Türkiye based on female specimens. The new species is distinguished by its dorsocentral setal arrangement; namely, the absence of a pair of central setae (ex), which serves as a key diagnostic character. An updated key to the known species of Camerobia is also provided. Additionally, a pair of cupule-like depressions (ih) is described from the anogenital region of C. exnuda sp.n., resembling the fosssette-like paired micro-areas known from Stigmaeidae, and the possible homology of these structures is briefly discussed. Taken together, these findings expand the known distribution and diversity of Camerobia and provide additional data for understanding camerobiid morphology and taxonomy.
