A taxonomic revision of Neoserica (sensu lato): the species groups N. lubrica, N. obscura, and N. silvestris (Coleoptera, Scarabaeidae, Sericini)

Abstract

The species of the Neoserica lubrica Brenske, 1898, N. obscura (Blanchard, 1850) and N. silvestris Brenske, 1902 species groups are revised. The study resulted in the following new synonymies and combinations: Neoserica obscura (Blanchard, 1850) = Microserica roeri Frey, 1972, syn. n., = Maladera chinensis (Arrow, 1946), syn. n.; Neoserica hainana (Brenske, 1898), comb. n., and Neoserica minor (Arrow, 1946), comb. n. The known species are redescribed. The following nine new species are described from China: N. allobscura Ahrens, Fabrizi & Liu, sp. n., N. dongjiafenensis Ahrens, Fabrizi & Liu, sp. n., N. fugongensis Ahrens, Fabrizi & Liu, sp. n., N. mantillerii Ahrens, Fabrizi & Liu, sp. n., N. menglunensis Ahrens, Fabrizi & Liu, sp. n., N. pseudosilvestris Ahrens, Fabrizi & Liu, sp. n., N. sakoliana Ahrens, Fabrizi & Liu, sp. n., N. shuyongi Ahrens, Fabrizi & Liu, sp. n., and N. tahianensis Ahrens, Fabrizi & Liu, sp. n. A key to the Sericini genera with multilamellate antenna, species groups of Neoserica of mainland Asia, and species of the species groups examined here are provided. Maps of the species distribution are provided, habitus and male genitalia are illustrated.
