Definitions For Glossary Terms

EFFACED
See obsolete
ELONGATE
Much longer than broad (compare with oblong).
EMARGINATE
A margin with a notch or inwardly curved or angled 'cut out' portion (compare with truncate).
EMPODIUM
See arolium
ENTIRE
See percurrent
ENTIRE LINEA CALVA
A linea calva in which the bare band is continuous to the posterior margin of the wing, without any setae on the dorsal surface at some point within the band or across the posterior end of the band; by definition an entire linea calva is also an open linea calva, but not a closed linea calva or an interrupted linea calva.

EPICNEMIAL CARINA
A ridge or carina that is sometimes present anteriorly on the mesepisternum behind the procoxa, and which may continue under the coxae (see acetabular carina) to the discrimen, which delimits an epicnemium between itself and the procoxa and a mesosternal shelf between itself and the mesocoxae.

EPICNEMIUM
Term often used for an anteroventrally differentiated portion of the mesepisternum that lies under the procoxa and behind and below the prepectus, though rarely used for the ventral portion of the prepectus between the ventral surfaces of the prothorax and mesothorax. In either sense the epicnemium is not homologous with the epicnemium of sawflies (Symphyta) and is an analogous region to similar looking regions in other Apocrita. [photo]
EPIMERAL SCLERITE
See mesotrochantinal plate
EPIPYGIUM
Last tergite of the metasoma; used either as a synonym of syntergum or, in Torymidae, for a more or less separated and sclerotized, partly setose, often flap-like sclerite posterior to the eighth metasomal tergum in most females. [drawing]
EPISTOMAL MARGIN
See clypeal margin
EPISTOMAL SULCUS
When visible, sulcus that differentiates the clypeus from the rest of the lower face; sometimes used only for the mostly horizontal portion of the sulcus between the anterior tentorial pits (see also clypeogenal sulcus). [drawing]
ERECT
Upright, or projecting straight out from a structure (compare with adpressed and decumbent).
EXODONT MANDIBLE
Mandible in which the teeth are curved outward and the mandibles do not overlap when closed.
EXSERTED OVIPOSITOR
An ovipositor that projects distinctly beyond the apex of the last metasomal tergum. [photo][photo]
EYE
The paired organs of sight on the head that is composed of a large number of facets, sometimes referred to as the compound eye in contrast to the simple eye or ocellus. [drawing]
EYE MARGIN
One of four margins of a compound eye, the upper or dorsal margin, lower or ventral margin, inner or anterior margin, and outer or posterior margin; sometimes called the orbit. [drawing]
