Proarna grisea (Fabricius, 1775)

[ Tettigonia] grisea Fabricius 1775: 678 .

Type locality. America.

Remarks. Berg (1879) stated that he had a specimen from Jujuy that corresponded well to the existing description. Delétang (1919) lists Argentina within the distribution of P. grisea but provides no specific location data. He also stated that he had not seen any specimens. The distribution for the species includes the West Indies, Guyana, Northern Peru, Ecuador and Venzuela (Metcalf 1963a; Sanborn 2007a) so it appears the species is distributed in the northwestern portion of the continent. The reference to P. grisea by Berg (1879) probably concerns P. insignis which is similar in general appearance to P. grisea and is common in the cloud forests of the northwesten portion of Argentina. We remove the species until additional specimens collected in Argentina confirm the presence of the species in the country.
