Bocchus is a genus of wasps belonging to the family Charopidae. The genus was described by American entomologist William Harris Ashmead in 1892.




Taxonomy


Ashmead described the genus in 1893. It was originally a monotypic genus, with the only member (the current type species) being B. flavicollis.




Description


Ashmead's original text (the type description) reads as follows:

Head large, broad, shaped much as in Dryinus, but the vertex not impressed, the occiput very slightly concave; eyes large oval, prominent; ocelli small, close together in a triangle. Antennae 10-jointed, subfiliform, very slightly thickened toward tips, inserted Just above the clypeus, the scape longer than the first flagellar joint.
Maxillary palpi 4-jointed.
Mandibles 3-dentate, nearly equal, the inner tooth a little the smallest.
Thorax not much lengthened, much narrowed anteriorly and truncate posteriorly, the angles of the truncature rounded; the pronotum is almost as long as the mesonotum but much narrower, a little wider anteriorly than at base, only about half the width of the very broad head; mesonotum wider than long, with furrows; scutellum semicircular with a transverse furrow all across the base; metathorax much shorter than high, abruptly truncate.
Front wings with a lanceolate stigma, two basal cells, and an open marginal cell, the radius being long and curved.
Abdomen globose, distinctly petiolate, the petiole blender, cylindrical, as long as the hind coxae.

Legs as in Dryinus, the anterior tarsi chelate, the fourth Joint not much larger than the third.




Distribution


The genus has a cosmopolitan distribution.
