Melikaiella bicolor n. sp.
sexgen

Hosts: Quercus acherdophylla, crassipes, laurina, crassifolia, rugosa [the authors state that all hosts are members of section Lobatae (as is true of all the members of new genus Melikaiella), but Quercus rugosa is not in Lobatae. This may be a mistake?]

Gall. (Fig. 7). Plurilocular. Distal part composed of strongly swollen young branches (20-30 x 30-40 mm). More or less circular or oval in cross-section; larval chambers (3x1.7 mm) are nested perpendicularly to the longitudinal axis of the branch, occupying radially the entire space of the gall in cross-section. Green, easily cuttable; brown after the adults emerged and hard interiorly; the external epidermis and the tissue between larval chambers are easy to cut. Surface smooth, verrucose where the leaf petioles are inserted.

Range: Mexigo (Hidalgo and Tlaxcala)

Biology: Galls develop in May and mature in June. Adults start to emerge in June. In August many parasitoids of Eulophidae, Eurytomidae, Eupelmidae Pteromalidae and Ormyridae (Chalcidoidea), and several Synergus (Cynipidae) inquilines were obtained.
