Abstract

There are four species of Gymnetron in China recorded to date including G. miyoshii Miyoshi, 1922, G. villosipenne Roelofs, 1875, G. auliense Reitter, 1907 and G. vittipenne Marseul, 1876, of which the last two are new country records. The pre-imaginal stages including eggs, mature larvae and pupae of G. miyoshii, G. auliense and G. vittipenne are described and illustrated. In addition, their diagnostic characters (larvae and pupae) are discussed and differentiated, and notes on some of their biological parameters are provided. Potential ecological impacts between Gymnetron weevils and their host Veronica spp. also are provided.
