New species of Hambletonia Compere (Hymenoptera: Encyrtidae) in Dominican amber

Abstract

The present paper describes a new species of encyrtid wasp, Hambletonia dominicana sp. nov. (Hymenoptera: Encyrtidae) from Dominican amber. Diagnostic characters include long antennae that are almost twice the length of the head, the absence of long, coarse, flattened setae on the dorsal apical margin of the pedicel, and an elliptical club subequal in length to that of the funicle. This first described fossil species of Hambletonia provides views of new and possible unique morphological features of encyrtid wasps that existed in the Neotropics during the mid-Tertiary.
