Etymology

The genus name Wallaceaphytis is derived from the family name of Alfred Russel Wallace, and the generic name Aphytis , to which it is related. Other genera within the subfamily Aphelininae , to which Wallaceaphytis belongs, include Neophytis , Paraphytis and Punkaphytis . The genus is described in honour of Wallace, co-discoverer with Charles Darwin of the theory of evolution by natural selection. Wallace’ s collections and observations on the fauna and flora during his extensive travels in South East Asia, including the island of Borneo, led to his formulation of the theory. The genus and species are described on the exact date of the centenary of his death.

The specific epithet kikiae is based on, and in honour of, “Kiki”, the second author’ s mother, Mrs Christian Duke.
