The genus Acipes Attems, 1937 in the Iberian Peninsula (Diplopoda, Julida, Blaniulidae), with the description of three new species from Spain

The blaniulid genus Acipes Attems, 1937 comprises eleven known species, distributed in Macaronesia and the Iberian Peninsula. Three of the four Iberian Acipes species have been recorded exclusively in subterranean environments: Acipes andalusius Enghoff & Mauriès, 1999, Acipes machadoi Enghoff & Reboleira, 2013 and Acipes bifilum Enghoff & Reboleira, 2013. In this work, we describe three new species of Acipes. Two of these species, Acipes celtibericus Gilgado & Enghoff sp. nov. and Acipes oligops Gilgado & Enghoff sp. nov., were captured in superficial subterranean habitats of central Spain. The third species, Acipes alicantinus Gilgado & Enghoff sp. nov., is described from specimens previously identified as Acipes andalusius Enghoff & Mauriès, 1999 captured in the superficial subterranean habitats in eastern Spain. We also present a comprehensive summary of the current knowledge and all available records of the Iberian Acipes, with a distribution map, and a key to all species of the genus. We include illustrations of the gonopods for all Iberian species. Additionally, we present the first pictures of the habitus and habitat of Acipes andalusius and Acipes continentalis Enghoff, 1986. We also provide new records of Acipes continentalis from subterranean and epigean habitats in several sites of Guadarrama Mountains.
