Peru — Lake Lavandera in Andes, 5140 m a.s.l. recorded as Halacarus processifer based on single protonymph ( Walter 1919a). Bartsch (2018) commented that Halacarus processifer (this was mentioned as Lobohalacarus processifer by Viets 1939b, Bartsch 2009) is species with vague descriptions but expected to belong to Lo. weberi .

Remarks: Lobohalacarus weberi is one of the most frequently recorded freshwater halacarid species. It was reported in subterranean and groundwater-fed surface waters, amongst sand, gravel and mosses. It also inhabits slightly saline (0.5–5 ‰) coastal sedi ments ( Bartsch 2014). Records are from the sea level to altitudes of 5140 m.
