ABSTRACT
Over recent years, intense field work in caves of Portugal has provided new data on the distribution of subterranean Iberian leiodid beetles. Speonemadus algarvensis sp. nov. is described from caves of southern Portugal. The new species is included in the Speonemadus Jeannel, 1922 escalerai-group (Cholevinae; Anemadini). All species of the S. escalerai-group are revised and S. breuili (Jeannel, 1922) is resurrected as a valid species. A key to identify the species of the S. escalerai-group is provided and the distinctive characters are illustrated. The distribution of all species of the group is mapped with new data together with biogeographic considerations.

ABSTRACT
The new hypogean ground beetle, Duvalius abyssimus n. sp., from Krubera-Voronja, world’s deepest cave (Arabika massif, Western Caucasus) is described and illustrated. Diagnostic morphological characters of the imago, male and female genitalia are provided. Its relations with other Duvalius Delarouzée species from the Western Caucasus geographic area are discussed. An updated overview of the biocoenosis of its peculiar habitat is made.
