An unexpected new subgenus and species of Campodeidae (Diplura), Plusiocampa (Pentachaetocampa) inopinata subgen. et sp. nov., a troglobitic species found in Schallsinger Höhle in an isolated karstic region in southwestern Germany is described. The new taxon shows two unique characters for the genus Plusiocampa: five dorsal femoral macrosetae and t...

... Campodeinae, the most diverse and abundant subfamily in soils in every continent except Antarctica (Condé 1956a), are widely distributed from humid areas to deserts and also tropical forests. Only 36 out of the 300 species of Campodeinae colonize cave habitats, in contrast to the Plusicampinae and the tachycampoid lineage, in which most of the species show adaptations to cave habitats in karst and volcanic territories (Sendra et al. 2016(Sendra et al. , 2017c(Sendra et al. , 2020aSendra & Weber 2018). ...

Campodeinae is the most diverse subfamily of Campodeidae diplurans and inhabits soils and subsurface ecosystems. These are distributed in the Palearctic area, clearly rarifying towards northern latitudes. The major taxonomic characters are chaetotaxy, shape and complexity of pretarsal structures, and secondary sexual characters. This monograph provides a taxonomic revision of the subfamily Campodeinae in the Euro-Mediterrnean region, based on extensive literature review and new material studied. It comprises detailed morphological descriptions and illustrations together with habitat and distribution data of 161 species and 14 subspecies from 10 genera: Campodea Westwood, 1842, Edriocampa Silvestri, 1933, Eutrichocampa Silvestri, 1902, Helladocampa Condé, 1984, Libanocampa Condé, 1955, Litocampa Silvestri, 1933, Oreocampa Condé, 1950, Podocampa Silvestri, 1932, Remycampa Condé 1952, and Spaniocampa Silvestri, 1933. With 116 species Campodea is the most diverse and widely distributed genus in the studied area.

... The genus Plusiocampa has been divided into four subgenera based on two characters: the presence of the femoral dorsal macrosetae (Condé 1955a;Paclt 1957;Sendra & Weber 2018) and the number of tibial ventral macrosetae (Bareth & Condé 1984). Based on these synapomorphies and other characters, the following taxonomic key is proposed for the current five subgenera and 69 species. ...

Diplura is a group of entognathous hexapods, often considered a sister group to insects. They play an important role in recycling organic matter in soil and subterranean terrestrial ecosystems. The Campodeidae is the most diverse family, divided into four subfamilies. The subfamily Plusiocampinae has a subterranean life-style with many species distributed in the Euro-Mediterranean area. The incertae sedis tachycampoids (“lignée Tachycampoïde”) is a group within the family Campodeidae that share with the Plusiocampinae a strong preference for subterranean habitats and several morphological characters, such as slender body shape, elongated appendages, considerable increment in the number of antennomeres and cercal articles, and complexity of sensorial structures. The present monograph provides a taxonomic revision of the subfamily Plusiocampinae and the genera belonging to the tachycampoid lineage from Europe and the Mediterranean region. It comprises detailed morphological descriptions and illustrations together with data on the habitats and distributions of 87 species, 10 subspecies and 11 affinis forms. Seven new species are described among those, namely: Plusiocampa (Plusiocampa) apollo Sendra, Giachino & Vailati sp. nov., P. (P.) chiosensis Sendra & Gasparo sp. nov., P. (P.) dublanskii Sendra & Turbanov sp. nov., P. (P.) hoffmanni Sendra & Paragamian sp. nov., P. (P.) rhea Sendra sp. nov., P. (P.) ternovensis Sendra & Borko sp. nov. and P.

A new genus of Plusiocampinae (Diplura, Campodeidae), Anatoliacampa diclensis Sendra, Tusun & Satar gen. et sp. nov., is described from specimens found in the Southeastern Anatolian Peninsula in Dicle cave (Bozaba village, Dicle district, Diyarbakır province, Turkey). Based on its morphological characteristics and molecular analysis, the new taxon undoubtedly belongs to the well-established subfamily Plusiocampinae and occupies, like most species of the subfamily, cave habitats. Anatoliacampa diclensis has two important features: its unique pretarsus and the abundant distribution of urosternal macrosetae. The finding of this new taxon is of high palaeogeographic interest, as it provides new evidence for establishing Anatolia as a land bridge for the colonization of the Euro-Mediterranean lands by cave-adapted Plusiocampinae and their few soil-dwelling relatives.
