A New Species of Discothyrea Roger from Mauritius and a New Species of Proceratium Roger from Madagascar (Hymenoptera: Formicidae)

摘要

The worker of Discothyrea berlita sp. nov. from Mauritius is described. This is the first record of the genus from Mauritius. D. berlita is known from a single locality, Le Pouce, a small sanctuary of native ants on an island overrun with invasive ant species. Proceratium avium is recollected at Le Pouce and is the senior synonym of Proceratium avioide de Andrade (syn. nov.). The practice of manually removing alien plants from native forest plots in Mauritius is not advised for the Le Pouce forest patch because this practice facilitates the establishment of invasive ants, which eliminate native ants. Proceratium google sp. nov. is described from Madagascar.
