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 , pit-reticulate in all other species; labrum somewhat shiny, interspaces pit-reticulate; scutum: interspaces almost smooth. Metasoma: interspaces pit-reticulate.
