This is an unsightly pouch gall that develops on the underside of the leaf blade as a concavity filled with erineum and on the upper side as a rounded outpocketing with irregular puckered domes. The pouch is greenish, becoming blackish, and the erineum turns brownish at maturity. The galls are variable in size and are frequently coalesced and crowded, giving a lumpy appearance to the leaf blade. Eriophyes sandorici has been found only on santol of the mahogany family Meliaceae, a tropical tree with edible fruit from the lndomalayan region and Mauritius.
