Host and locality– Holotype male, Rock and Pillar Range, CO, New Zealand, August 2001, from Hemideina maori ( Orthoptera : Anostostomatidae ) by Ian Jamieson, (ZQZ 101002 ­1). Deposited in the New Zealand Arthropod Collection (NZAC), Landcare Research, Private Bag 92170, Auckland, New Zealand. Paratypes, same data as holotype, 4 adult females, 6 larval females. Paratypes, St. Mary’s Range, CO, New Zealand, 11 February 2002, by Ian Jamieson, 4 adult females (ZQZ2002­1, ZQZ 2002­2, ZQZ 2002­3, ZQZ 2002­4). A fully developed male is inside female # ZQZ 2002­4.

Etymology– The genus Wetapolipus is named for the common name of the host insect, the New Zealand weta, and for part of the family name, Podapolipidae . Wetapolipus jamiesoni is named for the collector and specialist in weta ecology, Ian Jamieson.
