ANTENNA
(pl. Antennae) Pair of segmented appendage on the head which are mostly sensory in function. They are composed of a basal scape, pedicel and flagellum
ABDOMEN
The hindmost of the three main body regions of an insect. In some Hymenoptera including Eulophidae, the first abdominal segment is nearly fused with the thorax and the rest of the abdominal segments form an apparent abdomen which is referred to as “metasoma” or “gaster”
APPENDAGE
Any body parts such as the leg, antennae, maxillary palp etc articulated or attached to the body through a joint
ANTENNAL SENSILLUM
Sensory structures found in the funicle segments of the antenna or clava
APICAL SPICULLA
Needle-like spine sometimes from the tip of the clava also referred to as terminal spine
CLAVA
Distinct grouping of the apical flagellar segments of the antennae. Usually composed of 1-3 segments, rarely in 4 or 6 segmented in some Hymenoptera; they are usually are larger in size and/or partly to completely fused; They are also referred to as the club.
COMPOUND EYE
The paired organs of vision seen in the head, composed of large numbers of optical units or facets collectively referred to as compound eye
COXA
(Pl. Coxae) The basal segment of a leg which articulates with the thorax basally and the trochanter apically
CUBITAL VEIN
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 speculumor linea calva posteriorly; sometimes called the cubital vein if pigmented.
ENDOPARASITOID
An insect that lives within the body of another species and ultimately kills it.
EYE
See Compound eye
FEMUR
The third segment of leg from base, between trochanter and tibia, generally the largest segment.
FLAGELLUM
The segments of the antennae beyond pedicel are collectively referred to as flagellum. Flagellum which consists of individual funicle segments basally and distally grouped and clubbed segments called clava.
FORE WING
The anterior pair of wings articulated to the thorax in an insect
FORE OCELLUS
Unpaired, anterior, single, lenslike, photosensitive structure on top of the head. The hind ocelli and the fore ocellus together are placed as an ocellar triangle
FRONTAL GROOVE
Transverse groove on the face below the anterior ocellus that is above and not connected to the scrobal sulcus or interantennal area
FUNICLE
The flagellar segments between the anellus and clava are collectively called as funicle
FUNICULAR SEGMENTS
Individual segments of the funicle are called ad Funicular segments. F1 refers to the basal segment and F2 refers to the distal segment
GASTER
The metasoma, or the part of the abdomen in Apocritan Hymenoptera posterior to the waist.
HIND OCELLI
Paired, posterior, lenslike, photosensitive structure on top of the head. The hind ocelli and the fore ocellus together are placed as an ocellar triangle
HIND WING
The posterior pair of wings articulated to the thorax in an insect
MALAR SULCUS
Groove or line between the lower margins of compound eye and the margin of the mouth at the base of mandible.
MARGINAL SETAE
Fringe of setae arising along the margins of the fore and hind wing
MANDIBLES
A pair of mouthpart appendages lying anterior to the maxilla and used by insects for chewing
MEDIAN OCELLI
See Fore ocellus
MESOSCUTUM
Region of the mesonotum anterior to the transscutal articulation and scutellar-axillar complex
MESOSOMA
The middle part of apocritan wasps, consisting of thorax fused to the anterior parts of the abdomen (propodeum), anterior to the waist or petiole.
METASOMA
See Gaster. The last part of apocritan wasps, consisting of grouped posterior segments of the abdomen, posterior to the waist or petiole.
MIDLOBE OF MESOSCUTUM
Median or middle region of the mesoscutum that is differentiated from paired lateral lobes when notauli are visible
NOTUM
The dorsal or upper sclerite of a segment in the thorax
NOTAULUS
(pl. Notauli) Converging furrows on the anterior part of the mesonotum of small insects, as observed in Hymenopterans
OCELLI
Small lenslike, photosensitive structure seen on top of the head
OCCIPITAL SUTURE
See Vertexal suture
OVIPOSITOR
The egg laying appendage of female insects
PETIOLE
A narrow attachment base of the structure. In Hymenoptera it refers to the narrow segment connecting the propodeum and the gaster.
SCAPE
The first or basal-most segment of the antenna, which articulates with the head by the radicle.
SCLERITE
A hard, tanned, external plate bounded by sutures
SCUTELLUM
The posterior section of the notum
SCUTUM
The middle part of the notum
SETOSE
Hairy
STERNITE
A ventral sclerite
STIGMAL VEIN
Portion of the forewing vein complex that projects into the wing membrane from the apex of the marginal vein; measured from the point at which the stigmal vein and postmarginal vein unite, apically to where the vein appears to end.
SUBMARGINAL VEIN
Basal-most portion of the forewing vein complex that occurs behind the costal cell; measured from the constriction that delimits the humeral plate to the point at which the vein touches the leading edge of the wing apically.
TERGA
A dorsal sclerite.
VERTEX
Region on top of the head that is behind the anterior ocellus and between the eyes.
VERTEXAL SUTURE
Transverse groove on the top of the head that extends from the eye just anterior or posterior of the posterior ocellus; sometimes called the occipital sulcus.
