Phalangopsidae crickets from Espiritu Santo Island, Vanuatu (Insecta, Orthoptera, Grylloidea)

The long-legged crickets (Grylloidea, Phalangopsidae Blanchard, 1845) collected during the SANTO 2006 Global Biodiversity Survey are studied. Three genera (four species) are represented in the material at hand: three troglobitic species (Megacris lipsae n. gen., n. sp., Parendacustes sp. 1, Parendacustes sp. 2) and one epigean species (Brevizacla molisae n. sp.) widespread in Santo rainforests. The species are defined by their morphology and male and female genitalia, and their habitats documented. These taxa are briefly compared to New Caledonian Phalangopsidae.
