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., cerci) 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. [drawing]
