Pison marginatum is a wasp of the family Crabronidae.

It is found in Australia, South East Asia and many of the islands of the Pacific Ocean.

The species has a primarily black head and body, with occasional red tinge to the legs of some specimens.

[1] It can be distinguished from Pison spinolae due to the lack of long erect hairs.

[1] Pison morosum is found throughout Australia, Indonesia, Malaysia, the Philippines, Micronesia, Melanesia and Polynesia, as far north as Hawaii.
