Gonionota hydrogramma is a moth in the Depressariidae family. It was described by Edward Meyrick in 1912. It is found in Colombia.
The wingspan is 21-22 mm. The forewings are brown, with irregular pale transverse striae and with the posterior two-thirds of the costal edge rosy slightly tipped with white cilia, with a small oblique rosy mark at two-fifths and another mixed with white at four-fifths. The first discal stigma is blackish, the plical minute and blackish, rather beyond it, the second discal is represented by a minute transverse linear white mark and there is a dark brown dorsal streak from one-third to near the tornus, attenuated posteriorly, edged above with rosy-pinkish suffusion. There is also some indistinct blackish irroration towards the termen, tending to form subterminal and terminal series of spots. The hindwings are dark grey.
