A new cryptic species, Aleochara (Xenochara) castaneimarmotae Klimaszewski, Webster, and Brunke, new species (Coleoptera: Staphylinidae: Aleocharinae), associated with Marmota monax (Linnaeus) burrows and caves in eastern North America, is described and illustrated. A key to Canadian species of subgenus Xenochara Mulsant and Rey and revised distributions of the taxonomically difficult fumata species group are provided. Aleochara quadrata Sharp is recorded from Washington and Oregon for the first time.
Cave research in Hungary has developed a lot in the last decade. As a part of this progress, enchytraeid specimens were collected from Hungarian caves and were subsequently characterized by comparative morphological and molecular taxonomic analyses. Molecular phylogenetic studies based on ITS, CO1 and H3 sequences and morphological results confirmed that these specimens represented two species new to science. The descriptions of Fridericia baradlana sp. nov. and Fridericia spelaeophila sp. nov. are presented in this paper.
Recent samplings in cavities of the Iberian Peninsula led to the discovery of a new millipede species of the order Callipodida in one cave in the region of El Bierzo (León, Spain): Lusitanipus xanin sp. nov. In additional samplings (near that cave), more specimens of this new species were discovered in surface habitats. The species has various distinctive characteristics, such as its green colour, but the morphology of the gonopod has several similarities with that of Lusitanipus alternans (Verhoeff, 1893), indicating a close relationship between them. The diagnosis of the genus Lusitanipus Mauriès, 1978 has to be changed to accommodate the new species. The presence of crests in two different sizes is no longer a diagnostic character of the genus Lusitanipus, but of the species L. alternans. Lusitanipus xanin sp. nov. is the fourth species of the order Callipodida for the Iberian Peninsula, and the second species for the genus. Lusitanipus xanin sp. nov. seems to be an epigean but troglophile species.
