Remarks. Described as ‘ arcticus ’ by Murray (1907a; 1913) in both references there is a confusion between the species described as ‘ arcticus ’ and ‘ antarcticus ’. Murray (1907a) reported a single egg, similar to Macrobiotus hastatus that was smaller but with fewer and thicker rods (i.e. comparing with Acutuncus antarcticus egg description) from the Cape Colony. Later Murray (1913) indicated a “supposed egg of this species…” from Uganda (not Cape Colony) and “an animal like the adult of the species…” from Kikuyu. This species confusion and other limited information means the ‘African’ Hypsibius arcticus should be considered questionable and requiring verification.
