The study of the spider-wasps collected during the exploration of the Espiritu Santo Island (Vanuatu) led to the descriptions of a new genus in the tribe Ageniellini, Melanagenia n. gen., and two new endemic species Melanagenia penaoru n. gen., n. sp. and Anoplius santo n. sp. Priocnemis corynodes Vachal, 1907 is transferred to the genus Melanagenia n. gen.; and a lectotype is designated for Pompilus inquirendus Vachal, 1907. Some new data (synonymies and distribution) about Anoplius opulentus (Smith, 1860), a species widely distributed in the South Pacific Region, are also provided.
