Type
.
Apis zonata
Linnaeus, 1758 (original designation).
Diagnosis.
Length 10-14 mm; most species with blue, green, white, or occasionally orange, metallic hair bands on metasomal terga; pale paraocular markings present in both sexes; maxiliary palpus with 6 segments; S5 of male apicomedially broadly to narrowly emarginate; S6 of male with lateral depressions on apical third, sometimes with a median protuberance, tuft of black hair apicomedially.
Description.
The following description refers to the Australian species of
Zonamegilla
(see
Brooks 1988
for a full description of the subgenus).
Female. Structure.
Head: wider than long; inner orbits diverging above; f3-9 about equal in length.
Coloration
.
Integument black, except yellow or pale yellow marks on labrum, mandibles, clypeus, scape, paraocular and supraclypeal area (marks are ivory in
Amegilla pulchra
).
Pubescence
.
Head: gena with white hairs. Legs: forecoxa and femur posteriorly light ginger in
Amegilla paeninsulae
, white in all other species, hair of anterior face of femur and tibia white or ginger; mid and hind legs dark or black, but lighter coloured on apex of femur, on outer surface of tibia and on base of basitarsus. Metasoma: apical hair bands on T1-T4; parts not covered by hair bands dark brown or black in
A. alpha
, black in all other species.
Punctation
.
Head: clypeus somewhat shiny, close to dense punctation, interspaces pit-reticulate; labrum interspaces almost smooth in
Amegilla murrayensis
and
Amegilla adelaidae
, reticulate in other species. Thorax: scutum with small, shallow punctures; interspaces almost smooth. Metasoma: T1-T5 somewhat shiny, with fine, shallow punctures, interspaces pit-reticulate.
Male. Structure.
Head: wider than long; inner orbits diverging above; f3-10 about equal in length. Metasoma: apicomedial margin of T7 bilobed.
Coloration
.
Integument black, except yellow or pale yellow marks on labrum, mandibles, clypeus, scape, paraocular and supraclypeal area (marks are ivory in
Amegilla pulchra
).
Pubescence
.
Head: gena with white hair. Thorax: sterna pale orange in
Amegilla paeninsulae
, white in all other species. Legs: forefemur posteriorly with long, light coloured hairs; coxa greyish white in
Amegilla paeninsulae
, white in all other species; mid and hind legs: dark or black, with lighter coloured hairs on apex of femur, outer surface of tibia and basitarsus. Metasoma: apical hair bands on T1-T5; parts not covered by hair bands dark brown in
Amegilla walkeri
, black in all other species. S6 dark except in
Amegilla paeninsulae
,
Amegilla thorogoodi
and
Amegilla cingulata
.
Punctation
.
Head: clypeus dull, with open shallow punctures, interspaces rough pit-reticulate in
Amegilla karlba
