On Odontiomorpha Jacoby, 1900 with description of two new species (Coleoptera: Chrysomelidae)

摘要

A redescription of Odon-tiomorpha minuta Jacoby, 1900 (Natal) and a description of O. capensis sp. nov. (Cape Province) and O. cuprina sp. nov. (Cape Province) are provided; the position of the genus Odontiomor-pha Jacoby, 1900 is briefly discussed and its relationship to Odontionopa Chevrolat, 1836 is pointed out. Describing the new genus Odontiomorpha, for the new species 0. minuta, Jacoby (1900) arranged it in a group, namely Odontionopinae (following Chapuis 1874 and Lefevre 1885), which includedthe African genera Odontionopa Chevrolat, 1836, Obelistes Lefevre, 1885 and Phascus Lefevre, 1884. Odontiomorpha was later considered by Selman (1965,1972) in the tribe Golaspoidini due to the "pygidium grooved medially", together with the genus Platycorynus Chevrolat, 1836. The description of two new species of Odontiomorpha gives me the opportunity to reconsider the position of this genus.
