In this paper, we describe the new genus Pauropygus gen. n. which includes three minute species, blind and unpigmented, living in interstitial littoral habitats in tropical or subtropical countries. Two of these species are new to science (type species Pauropygus projectus sp. n. from New Caledonia and Pauropygus pacificus sp. n. from China); the third one, originally described in the genus Cry...

A new genus Dimorphacanthella is established for Tetracanthella anommatos Chen and Yin, 1984 and Dimorphacanthella mediasetasp. n. from China. The new genus exhibits an unusual metamorphosis: small juveniles, previously called Uzelia anommatos Yue & Yin, 1999 get the second pair of anal spines resulted from moulting and become "Tetracanthella". Species identity of forms with two and four anal s...

The genus Isotomodes Linnaniemi, 1907 can be easily recognized among Isotomidae because of its remarkable morphology and chaetotaxy of the last abdominal segments (Gama, 1963; Potapov, 2001); it comprises 34 worldwide species (Bellinger et al. 2014, Potapov 2001, Arbea 2006, Abrantes & Mendonça 2007, Thibaud 2008) mainly distributed in Europe (especially in Mediterranean region) and America, an...

The material for this study was obtained after intensive sampling in the colluvial mesovoid shallow substratum, or MSS, of Sierra de Guadarrama National Park using 33 subterranean devices (SSD). data were from first extraction traps between May and October 2015. This paper presents results Entomobryomorpha Börner, 1913, which part Collembola captured. Four families 12 genera have been studied: ...

Longstanding observations suggest that dissolved materials are lost from fresh litter through leaching, but the role of soil fauna in controlling this process has been poorly documented. In this study, a litterbag experiment employing litterbags with different mesh sizes (3 mm to permit soil fauna access and 0.04 mm to exclude fauna access) was conducted in three habitats (arid valley, ecotone ...
