Hydropionea is a genus of moths of the family Crambidae. The 13 described species are distributed in Central and South America. The genus was formerly treated in Spilomelinae, but it is now placed in Glaphyriinae. The larvae are found to feed on Capparis uniflora (Capparaceae), which fits with the general feeding habit of the subfamily Glaphyriinae of feeding on Brassicales.
