Previously recorded material: Loew’s holotype was collected by Wahlberg at “ N‘Gami ” According to
Brink (1955)
Wahlberg arrived at Ngami in April 1855 and was there until June when he moved further north. He returned for a few weeks in November of the same year.
As
vulpes appears to be active in late summer it is quite probable that his specimen was caught between April and June.
Oldroyd (1974)
records the species from Livingstone in Zambia. Remarks: A female collected near Vanzylsrus together with Prev (Orthoptera: Acrididae).
