A
Antennae	sensory organs consisting of the scape, pedicel and flagellum	Labelled antenna (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
Apterous	without wings
Areolet	a small inclosed area on the forewing	Labelled forewing (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
B
Brachypterous	partly winged
C
Carinae	ridges
Cosmopolitan	occurring throughout, generally in reference to world-wide occurrence
E
Ectoparasite	species whose larvae develop externally on the host
Endoparasite	species whose larvae develop internally in the host
Epicnemial carina	a carina (ridge) that is sometimes present anteriorly on the mesopleuron	Labelled lateral view of body (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984).
F
Face	part of the head below the antennal sockets and includes the clypeus	Labelled head (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
Flagellum	segments of the antennae excluding the pedicel and scape. Segments are numbered from the most proximal (which is 1)	Labelled antenna (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
Frons	part of the head above the antennal sockets of an insect's head, usually has an ocellus	Labelled lateral view of body (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984).
G
Glymma	pit-like structure on T1
I
Instar	a stage of a developing larva
M
Macropterous	fully winged
Malar space	space between bottom of the eye and mandible, sometimes with a groove	Labelled head (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
Mesopleuron	laterally, the middle segment of the mesosoma; containing the middle leg	Labelled lateral view of body (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984).
Mesoscutum	dorsally, the middle segment of the mesosoma	Labelled lateral view of body (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984).
Mesosoma	the combined thorax and propodeum. In most Hymenoptera the first abdominal segment (propodeum) is fused to the reduced metathorax	Labelled dorsal habitus (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
Metasoma	the abdomen less the propodeum (corresponds to the gaster of some authors)	Labelled dorsal habitus (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
N
Notauli	a pair of grooves arising from the front margin of the mesoscutum and extending posteriorly

Pedicel	the second segment of the antennae	Labelled antenna (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
Propodeum	the first abdominal segment in Hymenoptera. It is fused with the thorax to form the mesosoma. It is often subdivided by carinae into a number of areae	Labelled dorsal mesosoma (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)

T
T1	Tergite number 1
Tergite	tergites are hardened plates on the dorsal surface, for example on the metasoma. Numbered T1, T2, T3 etc	Labelled dorsal habitus (figures modified with permission from Noyes & Valentine 1989; and Gauld 1984)
