A New Species of Macrothemis From Central America with Notes on the Distinction Between Brechmorhoga and Macrothemis (Odonata: Libellulidae)

Thomas W. Donnelly


Macrothemis aurimaculata, a new species from Guatemala and Costa Rica, is closely related to M. inequiunguis (Calvert), but differs in abdominal color pattern, shape of superior appendage and posterior hamule of the male, and color of the frons. The two species differ from other Macrothemis in the shorter tooth of the tarsal claw. The most constant distinction between Macrothemis and Brechmorhoga is the narrowed discoidal field in the front wing in Macrothemis.
