Proamytta (Proamytta) insularis ( Chopard, 1958)

Griffini 1906: Amytta occidentalis Karsch, 1890

Chopard 1958; Xiphidiopsis insularis Chopard, 1958

Chopard (1958) described the new species Xiphidiopsis insularis from Roca Infante Dom Henrique in Príncipe (one male, three females). It was transferred by Beier (1966) into the "rather poorly defined genus" ( Naskrecki 2008b) Proamytta . This placement was confirmed by Naskrecki (2008b) who studied also the types. We include here provisionally the specimens identified with some doubts as Amytta occidentalis by Griffini (1906). These animals (one male and two females) were collected at exactly the same locality as Chopard's specimens and do not differ in any body dimensions (length of body, hind legs, tegmina, ovipositor). Griffini's specimens and the species were not mentioned by Chopard (1958) when describing his new Meconematine species. Griffini's material was also not studied in the revisions of Beier (1965) and Naskrecki (2008b). So the identity of Griffini's specimens has to be re-checked, but in our opinion is very likely that they belong to P. insularis .
