Abstract

Anomala hamuliphalla (Myanmar: Kachin State, Laos), A. macrorhynchos (China: Yunnan) and A. malivirens (Vietnam) spp. nov. are described. Anomala graminea Ohaus, 1905 is allocated into the genus Tonkinilla gen. nov. The following new synonyms are established: Choumala Kobayashi, 2008 = Anomala Samouelle, 1819; Choumala choui Kobayashi, 2008 = Anomala phalaena Ohaus, 1915. Anomala perplexa diana Zhang et Lin, 2008 is raised to a full species. The limits of the species group of Anomala dalmanni are discussed and a key for identification is given.

Diagnoses of new taxa. Anomala hamuliphalla sp. nov. is unique in the shape of the left paramere extended into a hook, and in the bifurcate distal tip of the basal plate of the aedeagus with the rami divergent.

Anomala macrorhynchos sp. nov. is similar to A. millestriga and A. punctatissima, but can be distinguished in the shape of the parameres.

Anomala malivirens sp. nov. is similar to A. diana, but differs in the shorter parameres with more rounded apices in profile.

Tonkinilla gen. nov. (type species: Anomala graminea Ohaus, 1905) is similar to Mimela in the presence of the prosternal process, but the latter is compressed anteroposteriorly instead of laterally. The new genus can be further distinguished from the known genera by the peculiar pilosity, exposed labrum, loss of the elytral epipleura and the shape of the aedeagus.
