Tracking the ice: Subterranean harvestmen distribution matches ancient glacier margins

2019

Biogeographic studies often underline the role of glacial dynamism during Pleistocene (1.806-0.011 Mya) in shaping the distribution of subterranean species. Accordingly, it is presumed that present-day distribution of most specialized cold-adapted (cryophilic) cave-dwelling species should bear the signatures of past climatic events. To test this idea, we modelled the distribution of specialized cold-adapted subterranean alpine harvestmen (Arachnida: Opiliones: Ischyropsalididae: Ischyropsalis). We found that the distance from the glacier margins during Last Glacial Maximum (LGM; about 22,000 years ago) was the most important predictor of their present-day distribution. In particular, the pe…

A new Diplura species from Georgia caves, Plusiocampa (Plusiocampa) imereti (Diplura, Campodeidae), with morphological and molecular data

2021

A new dipluran species, Plusiocampa (Plusiocampa) imereti Sendra & Barjadze sp. nov., from the deep zone in three caves in the Imereti region, Georgia, is described. This new troglobitic Plusiocampa is an addition to four others known Diplura from around the Black Sea region, two Dydimocampa and two Plusiocampa s. str. The present study also provides the first CO1 sequences for the Plusiocampinae taxa and the first molecular data for cave-dwelling Plusiocampa species. Although bootstrap values were low, the maximum-likelihood phylogenetic tree grouped Plusiocampa (P.) imereti Sendra & Barjadze sp. nov. with two Plusiocampa s. str. species from Eastern Europe. Morphologically, P. (P.…
