Glossary of terms
Abdomen = that part of the body posterior to thorax. The abdomen is strongly transversely segmented. The upperside, comprised of tergites, is often completely covered by the elytra but the last visible tergite, the pygidium, may protrude. The visible ventral segments are called abdominal ventrites. (Figs 1 and 2).
Abdominal ventrites = visible ventral segments of the abdomen. In Cetoniinae seven abdominal ventrites are visible on the underside with the first ventrite almost completely concealed by the hind coxae (Fig. 2).
Acute = sharply angled, at less than 90 degrees.
Alutaceous = covered with minute cracks like human skin.
Antenna (pl., antennae) = paired multi-segmented sense organ, arising from anterior margin of eye (Fig. 1). In Cetoniinae, the antennae are 10 segmented, segments 2-7 are small and segments 8-10 are strongly laterally lobed and folded together as a club.
Antennal club = the swollen end of the antenna formed by the greatly enlarged segments 8-10 (Fig. 1).
Anterior = at the front (Example Fig. 2).
Anterior angle = angle made between lateral and anterior edges or margins of any structure (Example Fig. 2).
Apex, apical (pl. apices) = the tip or end of any structure, away from the base.
Apico-lateral = region at junction of lateral and apical regions (Fig. 2B).

Attenuate, attenuated = gradually tapering apically.
Base, basal = the nearest part of any structure to the main body. In beetles, the base of the body is junction of the pronotum and scutellum or elytra. Therefore the elytral base is the part nearest the pronotum and the pronotal base is the part nearest the elytra.

Cuticle = the thick outer layer of the insect body.

Disc = the middle part of any large expansive structure, for example pronotum, elytron. Excludes the margins (Example Fig 2).
Dorsal = the upper surface of any structure.
Elytron (pl. elytra) = The elytra are located posterior to the pronotum and are the largest visible sclerites on the upperside (Fig. 1). They are modified fore wings and cover the abdomen and the hind wings. In Cetoniinae they are not raised when the beetle is flying.
Emargination = cut-out piece of an edge or margin.
Epipleuron (pl. epipleura) = the lateral edge of the elytron bent back on itself, defined dorsally by a prominent edge.
Excavated = with a hollowed out region.
Femur (pl. femora) = the third segment of the leg, located between the trochanter and the tibia (Fig. 2).
Frons = portion of the head situated between the eyes and posterior to the clypeus (Fig. 1).
Galea (pl. galeae) = outer lobe of the maxilla; used in the function of eating (Fig. 1).
Glabrous = smooth and hairless.
Genus (pl., genera) = a rank in taxonomy denoting a group of species considered to be more closely related to each other than to other species. The genus name must be in italics and with a capital first letter and is part of the name of a species eg Eupoecila australasiae.
Head = anterior part of the body, which contains most of the sensory organs (Fig. 1).
Humerus, humeral (pl. humeri) = the basal swelling of the elytron (Fig. 2B) which covers the attachment of the wing.
Impunctate = without punctures.
Lamellate = like plates, in reference to the antennal club segments of Cetoniinae (Fig. 1).
= oblong and tapering to end; spear-shaped.
Mandible = one of two opposed teeth in the mouth, not usually visible in Cetoniinae.
Margin = the area at the edge of any structure.
Mesepimeron = a lateral sclerite of the mesothorax (Fig. 2), visible on the ventral surface.
Mesoventrite = the median ventral sclerite of the mesothorax, formerly known as the mesosternum (Lawrence 1999).
Mesoventrite process = anterior swelling or projection of the mesoventrite between the mid legs (Fig. 1 and Fig. 2).
Mesothorax = the second or middle thoracic segment, bearing the mid legs and elytra (Fig. 1).
Metathorax = the third or posterior thoracic segment, bearing the hind legs and functional wings (Fig. 1).
Metaventrite = the median ventral sclerite of the metathorax, formerly known as the metasternum (Lawrence 1999) (Fig. 1 and Fig. 2).
Microtrichiae = minute cuticular hairs.
Mucronate = describing a process with concave sides narrowing to an acute tip (Examples Figs. 1B and 2).
Notch = narrow indentation of an edge or margin (Example Fig. 3C).
Obtuse = shallowly angled, with apical angle greater than 90 degrees (Fig. 1).
Posterio-lateral = behind and to the side.
Posterior angle = angle made between the lateral and posterior edges or margins of a structure.
Process = an extension of a surface, of a margin, or of an appendage..
Pronotum = large dorsal sclerite located between the head and the elytra, the dorsal part of the prothorax.
Prothorax = the first or anterior thoracic segment, bearing the front legs, but no wings (Fig. 1).
Pubescence = covering of setae..
Puncture = small pit in cuticular surface, often with a seta. .
