“…It is an interesting character for Neelipleona systematics at the genus level. The intrageneric stability of the pattern is supported by observations on three species of Neelus Schneider 2017) and eight species of Megalothorax (Schneider & D'Haese 2013;Schneider et al 2016;Schneider 2017).

Abstract.A new species of the genus Spinaethorax Papáč & Palacios-Vargas, 2016, recently erected for two cave species of Mexico, is described from a Vietnamese cave. It differs from the Mexican species most noticeably by the dorsal chaetotaxy of the head (number and morphology of chaetae), the shape of S-chaetae on the third antennomere, the dorsal chaetotaxy of the abdomen and the chaetotaxy of the dens. The pattern of special τ-chaetae is described for the first time in the genus. The affinities between Spinaethorax and the other genera of Neelipleona are discussed. Spinaethorax is probably closely related to Neelus Folsom, 1896. A table of the differential characters is provided for the three known species of Spinaethorax. Spinaethorax appears to be restricted to caves, but its presence in Vietnam indicates that this genus has a much larger distribution than previously recognized.

Springtails can occur in large populations on the snow surface. This peculiar habitat hosts specialized winter-active springtails living in colonies and using this seasonal habitat for feeding, effective dispersal and migration. Snow-active species have never been studied in Southern European Alps: the aim of this work is to study snow-active springtails of Adamello-Brenta Nature Park (“PNAB”; Italy), a peripheral mountain range of relevant biogeographic interest using integrative taxonomy. Springtail “bloomings” were sampled for 17 months by an environmental assistant of the park. Nine assemblages of springtails were found when temperatures were higher than 0 °C; eight were monospecific, with a total of five species found. The snow-active springtail fauna found includes both common Central-Northern European nival species like Desoria hiemalis (first record for Italy, although genetically differentiated from Northern Alps populations), Ceratophysella sigillata (known in Italy mainly from caves) and three species likely new to science (Hypogastrura cf. kelmendica sp1, Hypogastrura cf. kelmendica sp2, H. cf. peloponnesica, all belonging to the Hypogastrura socialisgroup). Snow is an important ephemeral habitat for springtails, for the biodiversity hosted and for its importance as an ecological corridor. We could hypothesize that snow, especially in peripheral mountain chains, acts as a fragmentary ephemeral habitat for those cold-adapted springtails. This could constitute a relevant aspect to take into consideration for conservation biology, especially in the context of the ongoing climate change. On the other hand, the Alpine chain probably acts as an ecological barrier for nival species, since isolated species and populations were found in PNAB. Graphical Abstract

The springtailMegalothorax laevisDenis, 1948 is redescribed from a broad sampling in the intertropical zone: Vietnam (including type locality), Ivory Coast, Gabon, Réunion island and French Guiana. Pseudopore-like elements are for the first time reported on the trunk and legs ofMegalothoraxspecies. New molecular data forM. laevis(16S rDNA, 28S rDNA d1 and d2 and COI Barcode) are provided. The phylogenetic position of the species within theMegalothoraxgenus is analysed.Megalothorax laevisbelongs to theincertusgroup but shares similitudes with theminimusgroup acquired through evolutionary convergences (such as smooth lamellae of the mucro). Those similitudes might have created confusion betweenM. minimusandM. laevis. WhileM. minimusused to be regarded cosmopolitan,M. laevishas been overlooked since its original discovery. However, the present sampling led us to believe thatM. laevisreplaceM. minimusas the commonest edaphicMegalothoraxspecies in the intertropical zone. A key to theMegalothoraxspecies with smooth mucro lamellae is provided.
