ZooBank: urn:lsid:zoobank.org:act:266F54B4-1F85-4EBF-A136-E17DA01AA560

TYPE SPECIES: Paracolletes subpunctatus Rayment, 1935 .

DIAGNOSIS: This genus is superficially similar to Leioproctus s.str., in that they both have finely ciliate inner metatibial spurs in females. However, the scape is short, not reaching the median ocellus and the pterostigma is short, shorter than half as long as the costal portion of the marginal cells.

ETYMOLOGY: The new genus-group name honors Ken Walker, one of Australia’s foremost authorities on bees, combining his surname with the Latin noun apis (meaning, “bee”). The gender of the name is feminine.
