VALVIFER
(pl., valvifers) The basal plates of the ovipositor (see also gonocoxa, first valvifer, and second valvifer).
VENATION
The complete system of veins of a wing, which in the chalcidoid forewing usually consists of a submarginal vein, marginal vein, postmarginal vein, and stigmal vein.
VENTRAL / VENTRAD
At or toward the bottom or lower surface of the body or structure (below). [drawing]
VENTRAL FRAME OF PHALLOBASE
The thickened, longitudinal, ventromedial cuticular margins of the phallobase if the phallobase is not continuous ventrally but has a median longitudinal opening.
VENTRAL PLAQUE
Carina or flange along the ventral edge of the scape, which often has a region of pores or other sensory patch. [drawing]
VENTRAL PROCESS
Paired papillae or tubercle-like structures on the ventral surface of the phallobase lateral to the ventral ridge at or near the base of the intervolsellar process. [photo]
VENTRAL RIDGE
Median cuticular thickening of the ventral surface of the phallobase that may be continued posteriorly as the intervolsellar process between the volsellae. [photo]
VENTRO-
Prefix meaning toward the bottom or lower surface of a structure, e.g. ventrolateral. [drawing]
VERTEX
Region on top of the head that is behind the anterior ocellus and between the eyes (see also temple). [drawing][photo][photo]
VERTEXAL SULCUS
Transverse groove on the top of the head that extends from the eye just anterior or posterior of the posterior ocellus; sometimes called the occipital sulcus (see also ocellar-ocular groove). [photo][photo][photo]
VOLSELLA
(pl., volsellae) Posteromedially differentiated lobe of the phallobase that usually has one or more curved spines apically (see also digitus). [drawing][photo]
VOLSELLAR SETA
Seta that originates from near the apex of the volsella basal to the digitus of the genitalia of some chalcid males. [drawing][photo]
