A New Species of Hesperotyphlus (Coleoptera: Staphylinidae: Leptotyphlinae) from Spain and Key to the Hesperotyphlus besucheti Species Group

The edaphic genus Hesperotyphlus Coiffait is distributed exclusively in the western Iberian peninsula. Several groups of species are proposed, based mainly on Coiffait’s publications. A key to species of the Hesperotyphlus besucheti Coiffait group is provided. Hesperotyphlus reyesae n. sp., belonging to the latter group, is described from Galicia (Spain). Among the H. besucheti group, H. reyesae is close to H. novoai Outerelo based on similarities between the male genitalia. The species was found in an Atlantic deciduous forest, living in the humus layer. Male genitalia and other morphological features of several species are illustrated.RESUMEN El género ed?fico Hesperotyphlus Coiffait est? distribuido exclusivamente por la parte occidental de la Pen?nsula Ibérica.
