Abstract

Abstract:
Zethus stangei 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.

Resumen:
Se describe a Zethus stangei Porter, especie nueva, de Costa Rica, cuyas características más notables la colocan en su propio grupo, siendo ellas las grandes y abultadas mandíbulas y el clípeo achicado del macho, la tibia intermedia con un solo espolón apical, y el segundo esternito con un lóbulo medio-apical. Al principio se le consideraba como perteneciente a Zethus magretti Zavattari pero estudios más recientes del tipo de esta especie demuestran que es un miembro del grupo coeruleopennis.
