Reticulodermis lithogalla gen. nov. and sp. nov. of oak gall wasp from Mexico (Hymenoptera, Cynipidae)

Abstract

A new genus of oak gall wasp, Reticulodermis Pujade-Villar, Cuesta-Porta & Melika gen. nov. and a new species R. lithogalla García-Martiñón & Pujade-Villar sp. nov. are described from Mexico. Reticulodermis is known only from the asexual generation that induces galls on leaves of Quercus crassipes Humb. & Bonpl. (section Lobatae). We provide the diagnosis, distribution and biological data on the new species. An identification key to the genera of oak gall wasps inducing galls on the section Lobatae is given.
