Abstract: | ABSTRACT Six new species of Orasema are described. Four species are placed into a newly recognised lasallei species group: Orasema lasallei sp. nov. (Costa Rica, Honduras, Mexico, Nicaragua), O. janzeni sp. nov. (Costa Rica), O. peckorum sp. nov. (Brazil) and O. vasquezi sp. nov. (Colombia). One species is placed in the wayqecha group, Orasema masneri sp. nov. (Ecuador). One other species is currently unplaced to species group, O. longinoi sp. nov. (Costa Rica). Orasema lasallei was taken from a nest of Pheidole vorax (Fabr.) and an undescribed species near O. longinoi from a nest of Pheidole dossena Wilson (Myrmicinae). The morphology of the digitate labrum is discussed with respect to other Eucharitidae. |
