Definitions For Glossary Terms



CALCAR
Term used for a curved, bifurcate or otherwise modified tibial spur of the front leg, which together with a strigil forms an antennal cleaning organ. [photo]
CALLAR FURROW
In Eupelmidae, a transverse furrow along the anterolateral margin of the propodeum anterior to each spiracle. [photo]
CALLAR REGION
In female Eupelmidae, paired regions of the propodeum lateral to the plical furrows or the region lateral to each spiracle if there are no plical furrows and the callar regions and plical region are not differentiated. [photo]
CALLUS
The area of the propodeum lateral to each spiracle or postspiracular sulcus, which is often convex and at least partly setose. [drawing][photo]
CAMPANULATE
Bell-shaped.
CAPITATE
Knob-like or button-like.
CAPITATE PEG SENSILLUM
Mushroom-shaped sensory structure on the flagellum, particularly the clava; sometimes called the sensilla ampullacea.
CARDO
(pl., cardines) Basal section of the maxilla, by which the maxilla is attached to the head capsule. [drawing] [photo][drawing]
CARINA
A ridge or small keel on a sclerite.
CAUDAD
Toward the posterior or rear end.
CEPHALAD
Toward the anterior or front (head) end.
CERCAL BRISTLES
Term sometimes used for the long setae on the cercus. [photo]
CERCAL PLATE
Term sometimes used for the type of cercus that looks like a flat disc from which several long setae project. [photo]
CERCUS
(pl., cerciadv., cercal) Paired sensory structures on the last or second last metasomal tergite; the cercus is sometimes a setose finger-like projection that articulates with the tergum, but more often it looks like a low tubercle or plate-like structure that bears several long setae (see cercal plate); sometimes called the pygostylus. [drawing] [photo][drawing]
CHEEK
Side of the head between the base of the mandible and lower margin of the eye, consisting partly of the lower face and partly of the gena.
CHELATE STRUCTURE    See digitus
CHITINIZED RIDGE    See ventral ridge
CLAVA
Apically differentiated region of the flagellum usually composed of 1-3 segments, rarely 4 segments, and exceptionally (Rotoitidae) 6 segments; the claval segments usually are larger in size and/or partly to completely fused; often called the club. [drawing]
CLAVAL SEGMENTS
One to six apical segments of the antennal flagellum that form a differentiated region, the clava. [drawing]
CLAVATE ANTENNA
An antenna that looks more or less club-like because the segments of the flagellum are widened distinctly toward the apex.
CLOSED LINEA CALVA
A linea calva that is entirely or substantially enclosed posteriorly by a line or lines of setae on the dorsal surface of the wing (see also open linea calva and interrupted linea calva). [drawing]
CLUB    See clava
CLYPEAL MARGIN
Ventral or lower margin of the clypeus that forms all or part of the median portion of the mouth margin on the front of the head. [drawing][photo]
CLYPEOGENAL SULCUS
Term sometimes used for the lateral, more or less vertical portion of the epistomal sulcus below each anterior tentorial pit. [drawing]
CLYPEUS
Median region of the head above the mouth that is often distinguished from the rest of the lower face by a difference in sculpture, but whose exact boundaries sometimes are indicated by the epistomal sulcus. [drawing][photo]
COLLAR
Subhorizontal surface of the pronotum that is posterior to the neck. [drawing][photo][photo]
COLLUM    See neck
COMPLETE NOTAULUS
Notaulus that extends posteriorly to the transscutal articulation. [drawing]
COMPOUND EYE    See eye
CORDATE/CORDIFORM
Triangular with the corners of the base rounded.
CORONAL SUTURE
In Mymaridae, median groove or a pair of grooves on the back of the head extending from the vertexal sulcus and converging toward the occipital foramen. [photo]
COSTAL CELL
The membranous region of the forewing anterior to the submarginal vein, measured from the basal constriction that delimits the apex of the humeral plate of the wing to the point at which the submarginal vein touches the leading edge of the wing. [drawing]
COSTULA
(pl., costulae) Transverse ridge on the propodeum near its middle. [drawing][photo][photo]
COXA
(pl., coxae) The basal segment of a leg, which articulates with the thorax basally and the trochanter apically. [drawing][photo]
COXAL FORAMEN
Openings in the body wall of the thorax to which the coxae are articulated. [photo]
CRANIUM
The head capsule.
CU1    See first branch of cubital vein (cu1) setal line
CU2    See second branch of cubital vein (cu2) setal line
CUBITAL FOLD
Longitudinal, convex fold near the posterior margin of the forewing that is directed from near the base of the submarginal vein to or partly to the apical margin of the wing, and which often has a line of setae (see cubital setal line) that forms the posterior margin of the basal cell and sometimes closes the speculum or linea calva posteriorly; sometimes called the cubital vein if pigmented. [drawing]
CUBITAL SETAL LINE
Row of setae on the dorsal surface of the forewing near its posterior margin, which is directed longitudinally from near the base of the submarginal vein to or partly to the apical margin of the wing (see also cubital fold and subcubital setal line); in Trichogrammatidae termed CU2 or second branch of cubital vein.
