Neuroterus elvisi Medianero & Nieves-Aldrey sp. n. (Figs. 1, 2 & 7C-F)

Gall (Figs. 8F-H). Small, irregular swellings of the leaves, with smooth and bare surface. Polythalamous, developing in petiole and midrib and engulfing leaf lamina. The galls are light green when fresh but dark green when mature and brown when old. Diameter 10 to 18 mm. Galls are relatively common on Quercus bumelioides at the Volcán Barú site. The gall most closely resembles that of Neuroterus junctor from Mexico.

Distribution. N. elvisi was found at 1,800 m above sea level at Volcán Barú, Chiriquí Province, Panama.

Etymology. Named after Elvis Segundo for his help in field work and oak gall wasps samplings in the mountains of Panama.

Biology. Sexual generation. Galls formed in the leaves of Q. bumelioides mature in May and insects emerge soon thereafter in the same month.
