Hydropionea is a genus of moths of the family Crambidae.

The 13 described species are distributed in Central and South America.

[2] The genus was formerly treated in Spilomelinae,[2] but it is now placed in Glaphyriinae.

[3] The larvae are found to feed on Capparis uniflora (Capparaceae),[4] which fits with the general feeding habit of the subfamily Glaphyriinae of feeding on Brassicales.
