Definitions For Glossary Terms
- BASAL / BASE
- 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. [photo]
- 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
