Abstract
Glaciologists have suggested that because of the extent of the ice sheets during the last glacial maximum (LGM) in Antarctica no terrestrial species could have survived these harsh conditions. However, substantial evidence suggests that some invertebrate species did indeed survive the LGM. We hypothesize that S. lindsayae survived the LGM in Antarctica through hypothetical refugia, areas that remained ice-free during the LGM. These are coastal areas characterized by high elevation, which would have remained ice-free during the LGM and would not have been inundated under episodes of elevated sea levels.
