Diagnosis.
Amegilla viridicingulata
is a distinctive species with orange-brown scutal pubescence, tergal hair bands with green iridescence and orange hair on the hind legs in both sexes. Females have a hind tibial scopa without a dark streak and T5 with a broad area of scattered white hair above the fimbria (Fig.
36
). Males have pale hair across the sterna, particularly S3, 4 and a distinctive S7 (Fig.
49
).

Coloration
.
Pale yellow marks on labrum, mandibles, scape, clypeus, paraocular and supraclypeal areas, inverted T-shape on clypeus; f2 red-brown ventrally, remainder of flagellum brown ventrally.
Pubescence
.
Head: labrum white, light ginger intermixed with black hair on clypeus, paraocular areas, frons, near ocelli and on vertex, gena white, light ginger towards vertex. Thorax: scutum ginger intermixed with black hair; pleura ginger with few black hairs under wing base, white ventrally; thoracic sterna light ginger; propodeum laterally ginger with few black hairs. Legs: forefemur posteriorly with long white hair, outer surface of tibia and tarsus light ginger, inner surface of tarsus brown; mid legs black, except light ginger hair on apex of femur and on outer surface of tibia and basitarsus and a narrow line of light ginger hairs on posterior proximal part of femur; hind legs black, except ginger hair on apex of femur, posterior rim of the outer surface of tibia and basal part of basitarsus, a white tuft on the apex of tibia; basitibial streak absent. Metasoma: apical hair bands on T1-T4 light orange-brown with clear green iridescence; T5 laterally white, fimbria brown, medial patch well developed, centrally white, laterally greyish-white and narrowing, medial streak overlapping fimbria (Fig.
36
); S3, S4 dark with posterolateral patches of white hair; S5 dark.
Punctation
.
Head: clypeus with close, medium, deep punctures, 0.1-1.0 puncture widths apart; labrum somewhat shiny, with close, small, shallow punctures, 0.3-1.0 puncture widths apart. Thorax: scutum shiny, with close punctures 0.1-0.7 puncture widths apart. Metasoma: T1-T5 with close to open punctures, 0.5-2.0 puncture widths apart.
Male

Length 11 mm; forewing length 8 mm.
Structure.
Head: shortest distance between eyes 0.7

x
OOD. Wings: length of marginal cell equal to distance from apex of marginal cell to wing tip; length of vein M of hind wing 1.6
x
length second abscissa of M+Cu; length of jugal lobe about 0.3
x
length of vannal lobe. Metasoma: apicomedial emargination of S5 wide and shallow; S7 with very wide medial ridge, resulting in a flattened apex with no apical projection, very small weakly pigmented areas and an inverted T-shaped brush, weak and broadened towards the apex (Fig.
49
); S8 apical emargination deep.
Pubescence
.
Head: labrum white; clypeus and paraocular areas predominantly black, remaining areas with scattered black hair on frons, near ocelli and on vertex; gena white, ginger towards vertex. Thorax: scutum ginger intermixed with black hair; pleura light brown with green iridescence; propodeum laterally ginger. Legs: forefemur posteriorly with long white greyish hair, outer surface of tibia and tarsus pale brown, inner surface of tarsus brown; mid legs dark, except pale brown hair on the apex of femur,
posteriorly
proximally on femur and on outer surface of tibia and basitarsus; hind legs black, except light ginger hair on apex of femur and outer surface of tibia, light ginger patch on base of basitarsus, white tuft on apex of tibia. Metasoma: apical hair bands on T1-T5 light orange-brown with green iridescence; T6 with a row of pale ginger hair on apical margin, remaining hair black when viewed from behind, brown when viewed from the side; T7 black; S2-S5 greyish white.
Punctation
.
Head: clypeus punctures 0.5-2.0 puncture widths apart; labrum: medium, shallow punctures 0.8-2.5 puncture widths apart. Thorax: scutum shiny, close to open, medium, shallow punctures, 0.2-2.5 puncture widths apart. Metasoma: T1-T5 somewhat shiny, with close to open, fine, shallow punctures, 1.0-2.0 puncture widths apart.
Variation.
Some males had white metasomal hair bands with blue reflections, making them difficult to recognise before dissection.
