Studied type specimens.

Guyana • 1 ♀, holotype of Microdon flavipennis Curran; Bartica; 5 Apr. 1901; C.W. Johnson leg.; MCZ. Label 1: "Bartica, BG / IV-5-1901"; label 2: "Collection / C.W.

Curran"; label 4 (red): "TYPE / Microdon / flavipennis / Curran"; label 5 (red): "Type / 7657"; label 6: "Jan.-July 2003 / MCZ Image / database"; label 7: " MCZ-ENT / 00007657".

Diagnosis.

Body length: female 17 mm. The alula is largely bare and cell br is largely bare posteriad of the vena spuria. These characters separate P. flavipennis from P. niger and P. pompiloides, two other species with a contrasting wing pattern. However, P. flavipennis is most similar to morph SUR-17b of P. normalis, from which it differs by the more extensive yellow in the wing and the different position of the dark cloud in the wing, as described in the key. Theoretically, P. flavipennis might be yet another colour form of P. normalis . However, with only the type specimen available and DNA data lacking, it seems better to be conservative with regard to the specific status of P. flavipennis .

Distribution.

Only known from the type specimen from Guyana.
