Loxaulus championi Medianero & Nieves-Aldrey sp. nov. (Figs. 1, 2 & 5A–D)

Etymology. Named after George Champion (1851–1926) English entomologist, collector of the first cynipid galls from Panama.

Gall (Fig. 5C–D). Elongated slight swellings of twigs (Fig. 5C). The gall surface rough, of the same colour as the bark. The swellings have at least two times the diameter of a normal stem. Larval chambers are arranged longitudinally in rows under the surface of the bark (Fig. 5D). The galled stems are barely recognizable before the emergence of the adults.

Distribution. Loxaulus championi was found between 2400 and 2700 m a.s.l. at Volcan Baru, Chiriqui, Panama.

Biology. Only the asexual generation is known, inducing galls on Quercus bumelioides Liebm. (section Quercus). The galls are found between July and December during the rain season in Panama.
