Two new species of Phratora Chevrolat from China (Coleoptera : Chrysomelidae : Chrysomelinae)

摘要

Phratora daccordii Ge and Wang new species and P. jinchuanensis Ge and Wang new species from Sichuan province, south-west China (Chrysomelidae: Chrysomelinae) are described. The distinctive characters of these new species in relation to others are discussed. Phratora daccordi resembles P. moha Daccordi most closely but is distinguished by the morphology of the antennae, the shape of lateral margins of pronotum, median lobe and spermatheca. Phratora jinchuanensis is allied to P. vulgitissima (Linnaeus), differing in the marginal bead along the pronotal base, median lobe morphology and bristles of the antennae. Illustrations of the habitus of P. daccordi, and median lobes and spermathecae of the new species are included. Type specimens are deposited in the Zoological Museum, Institute of Zoology, Chinese Academy of Sciences, China.
