Publication date: Available online 7 February 2020Source: Zoologischer AnzeigerAuthor(s): Rafael Jordana, Enrique Baquero, Enrique Ledesma, Alberto Sendra, Vicente M. OrtuñoAbstractThe material for this study was obtained after intensive sampling in the colluvial milieu souterrain superficiel (mesovoid shallow substratum, or MSS) of the Sierra de Guadarrama National Park using 33 subterranean sampling devices (SSD). The data were obtained from the first extraction of the traps between May and October of 2015. This paper presents the results for the Poduromorpha taxon, which was part of the total Collembola captured. Of the 17 species captured in this study, 11 had previously been cited in Guadarrama, four are new references, and two new species. Friesea ortunoi Jordana and Baquero sp. nov. is characterised as having seven eyes, tibiotarsus as having one clavate chaetae and only two spiniform chaetae on Abd VI. Schaefferia sendrai Jordana and Baquero sp. nov. is characterised as having six eyes, seven sensilla on Ant IV, a bi- or tri-lobed apical vesicle on the antennal tip, claws with internal tooth and lateral (posterior) tooth, dens with six chaetae and retinaculum with 5 + 4 teeth (asymmetrically). Based on the results of the study of the group of species of Xenylla Tullberg, 1869 that appeared, X. xavieri Gama, 1959 is separated from X. lotharingiae Thibaud, 1963 and a brief description of the latter is provided. The comparative study of the Schaefferia Absolon, ...
