Prokius lisethiae Medianero & Nieves-Aldrey n. sp.

Host plant. Quercus bumelioides Liebm (Fagaceae, Quercus section Quercus).

Gall (Figs. 6D-E). Galls have a spherical to lenticular shape with a smooth surface. They grow on the edge of the leaf blade, deforming the new leaf, measuring 5 × 2 mm. Galls typically grow in close clusters of 2–20 galls per leaf. The galls are reddish green when fresh and brown when mature. Galls are relatively abundant around Volcán Barú in Panama.

Distribution. Prokius lisethiae was found to 3,000 m a.s.l. at Volcán Barú, Chiriqui, Panama.

Biology. Only the sexual generation is known. Young galls are present in January during the dry season, growing on new leaves. The adult insects emerge from mature galls in late January and February.
