Bicyrtes viduatus is a species of sand wasp in the family Bembicidae.

[1] It is found in Central America.

[1] It is characterized by a pale yellow coloration, while lacking the thoracic "smiley face" pattern present on Bicyrtes capnopterus and Bicyrtes ventralis, the other two species in Bicyrtes having a yellow coloration.

Additionally, the submarginal cell is clouded, while the wings remain largely clear.
