Remarks.

Chen (1934) proposed this species based on two specimens from ZMHB with a reddish brown pronotum and elytra with eleven black spots including the obscure spot near the apex. Searching the ZMHB collection, I could not find any specimen matching the original description. However, the original description of G. subgeminata , with an illustration of the habitus, allowed its identification without any doubt.
