Examined specimen data from collection labels in Megachile (Austrochile) taxonomic revision

The species in the subgenus Austrochile Michener, 1965 (genus
Megachile) construct brood cells from resin that are stuck individually to
twigs or in clusters on the bark of trees. We therefore propose ‘resin pot
bees’ as common name for the bees in this subgenus. The species are
revised and redescribed, and 71 additional species are described. The
following names were synonymized:  Chalicodoma (Austrochile)
subferox Meade-Waldo, 1915 syn. nov. = Megachile (Austrochile) kirbyana
Cockerell, 1906 comb. nov.; Chalicodoma (Austrochile) recisa Cockerell,
1913 syn. nov., Chalicodoma (Austrochile) simpliciformis Cockerell, 1918
syn. nov., Chalicodoma (Austrochile) kirbiella Rayment, 1953 syn. nov. =
Megachile (Austrochile) modesta Smith, 1892 comb. nov.; Chalicodoma
(Austrochile) subremotula Rayment, 1934 syn. nov., Chalicodoma
(Austrochile) portlandiana Rayment, 1953 syn. nov. = Megachile
(Austrochile) rottnestensis Rayment, 1934 comb. nov.; Chalicodoma
(Austrochile) sexmaculata Smith, 1868 syn. nov. = Megachile (Rozenapis)
ignita Smith, 1853. All descriptions are accompanied by high resolution
diagnostic images and distribution maps. Data on flower visitation and
phenology are given. Dichotomous keys to both sexes of the species are
provided and interactive keys to the species will be available on the
LUCID website.
