TY - GEN A1 - Porter, Charles C. T1 - A remarkable new species of Zethus Fabricius (Hymenoptera, Vespidae, Eumeninae) from Costa Rica T2 - Insecta mundi : a journal of world insect systematics N2 - Porter, new species, is described from Costa Rica. It forms a species group of its own, unique in its grotesquely enlarged male mandibles and reduced clypeus, single mid tibial spur, and in having a medio-apical bulge on the second sternite. It was previously identified as Z. magretti Zavattari but reexamination of the type of this species shows that it actually belongs to the coeruleopennis species group.
