A new genus and species of Haplobainosomatidae (Diplopoda: Chordeumatida) from the MSS of the Sierra de Guadarrama National Park, central Spain

Abstract

The chordeumatidan fauna of the Iberian Peninsula is far from being well known, but recent efforts are improving that knowledge. Samplings carried out in the Milieu Souterrain Superficiel (also known as the Mesovoid Shallow Substratum) on several screes of the Sierra de Guadarrama National Park (central Spain) have led to the discovery of a new species of chordeumatidan millipede. This new species belongs to the family Haplobainosomatidae, which is mainly known from the northern Iberian Peninsula, and thus this is the first record of the family in central Spain. However, the extremely simple gonopods of this species are so different from all other known species of the family that it must be placed in a new genus. In this work, a complete description of the species, named as Guadarramasoma ramosae gen. & sp. nov., with a detailed iconography based on scanning electron microscopy images is provided together with a distribution map and a brief discussion of the implications of this new finding.

New species of Troglomyces and Diplopodomyces (Laboulbeniales, Ascomycota) from millipedes (Diplopoda)

“…The host is Guadarramasoma ramosae, a species collected in large numbers in traps set in the Mesovoid Shallow Substratum, MSS (Gilgado et al 2017). This is the first record of Diplopodomyces lusitanipodos from a species of the order Chordeumatida; previously known hosts belong to the genera Lusitanipus and Cyphocallipus (Callipodida), reported from Portugal and Spain (Santamaría et al 2014;Reboleira & Enghoff 2015Antić et al 2018).…”

“…Nevertheless, in the last decade, the interest in the millipede fauna of the Iberian Peninsula has increased, and several descriptions of new species have been made from specimens captured in caves (e.g. Enghoff & Reboleira 2013;Reboleira & Enghoff 2014;Mauriès 2013Mauriès , 2014Djursvoll 2019), shallow subterranean habitats (Gilgado et al 2015a(Gilgado et al , 2015b(Gilgado et al , 2017Akkari et al 2018), and on the surface (e.g. Akkari & Enghoff 2012, 2017Mauriès 2018;Recuero & Rodríguez-Flores 2020).…”
