is quite rare on Livingston Island and only found in a few samples from Byers Peninsula. The largest population was observed between small stones in a seepage area near Limnopolar Lake, continuously moistened by flowing water. It was also observed on James Ross Island (Van de Vijver & Kopalová, unpubl. results).
