Diachasma alloeum (Muesebeck, 1956)
Additional comments, can be found under the Diachasma page.
The ovipositor is distinctly longer than the body in Diachasma alloeum, and about equal in length to the body in the other two species of Diachasma. However, this character needs to be more critically examined because of potential allometry problems associated with hosts (and resulting parasitoids) that vary considerably in size.
This species superficially resembles Diachasmimorpha mellea, but the two can be readily distinguished by differences in the clypeus, which is short (broadly exposing the labrum) in D. alloeum.
