Definitions For Glossary Terms

BASAL / BASE
(adv., basally) The point closest to the body, at to toward the base of an appendage; synonymous with proximal. [drawing][drawing]
BASAL CELL
Basal region of the forewing that is enclosed anteriorly by the submarginal vein, posteriorly by the cubital fold or cubital setal line, if present, and depending on the setal pattern either the basal fold or basal setal line or linea calva apically. [drawing]
BASAL FOLD
Convex fold in the forewing, sometimes with a line of setae (see basal setal line), that is directed posterobasally from the parastigma and which forms the apex of the basal cell; sometimes called the basal vein if pigmented. [drawing]
BASAL SETAL LINE
Row of setae on the upper surface of the forewing that is directed posterobasally from the parastigma and that forms the apex of the basal cell (see basal fold). [drawing][drawing]
BASAL VEIN    See basal fold
BASITARSAL COMB
A row of flattened setae on the basitarsus that along with the calcar forms part of an antennal cleaning organ; in most chalcids the basitarsal comb consists of a longitudinal row of obliquely directed setae along the ventral margin of the basitarsus, though in some chalcids the row is very short and obliquely angled.

BASITARSAL NOTCH
A ventral emargination of the basitarsus of the front leg of most chalcids that have a curved foretibial spur, along which is aligned the basitarsal comb, and which together form the strigil. [photo]
BASITARSUS
Basal (first) segment of the tarsus. [drawing]
BASO-
Prefix meaning toward the base (part closest to the body) of an appendage, or region or margin of a sclerite closest to the transverse midline of the body, e.g. basolateral.
BIFID    See bifurcate
BIFURCATE
Partly divided into two parts (cleft, forked).
BRANCHED ANTENNA    See pectinate antenna
BROKEN SUBMARGINAL VEIN
A submarginal vein that appears to be 'broken' because the base of the parastigma narrows and is separated slightly from the rest of the submarginal vein. [drawing]
BUCCAL CAVITY    See mouth cavity
