Procystiphora
Procystiphora is a genus of gall midges (Cecidomyiidae) that induce galls in bamboo culms and branchlets. The genus is notable for possessing an inverted ovipositor—the first documented case in Diptera—where the ovipositor is dorsoventrally reversed relative to the typical orientation. Species have been described from Japan and China, where they develop within galls on Sasa and Phyllostachys bamboos respectively.
