TAXA MENTIONED AS OCCURRING

IN NEIGHBOURING ISLANDS

AND NOT OBSERVED IN SANTO

Some species are lacking in our samples and might occur in Espiritu Santo: the Phisidini Biproctis anatomensis Jin, 1992 , described after five specimens collected in Aneityum (south of the archipelago); Segestidea leefmansi (Willemse, 1940) is mentioned in Orthoptera species files ( Eades & Otte 2009) from Vanuatu, but this type locality data is erroneous, the holotype of S. leefmansi is from Papua New Guinea, New Hanover, Lavongai; Paragryllacris combusta (Gerstaecker, 1860) is mentioned from Vanuatu by Karny (1930a, 1937).
