03DC87BEE11BFFB7FF7FFB9C9AEDF4D9.taxon	diagnosis	Diagnosis. Roughly, currently Amiserica comprises species with an antennal club composed of three lamellae (both sexes), with a metafemur which has a serrated line adjacent to the anterior margin, and with a serrated line beside the dorsal margin of metatibia (at least in basal half).	en	Ahrens, Dirk, Liu, Wangang, Pham, Phu Van, Fabrizi, Silvia (2021): An overview on the genus Amiserica Nomura, 1974 (Coleoptera: Scarabaeidae: Melolonthinae: Sericini).

03DC87BEE11AFFB5FF7FFF009AECF2D7.taxon	discussion	Remarks. After the revision of extensive material of the genus Maladera Mulsant & Rey, 1871 from China (Fabrizi et al. 2021), we could recognize Amiserica loi Kobayashi, 1991 (based on the original description and without the need of examination of the type material) as representative of the subgenus Eumaladera Nomura, 1967: Maladera (Eumaladera) loi (Kobayashi, 1991), new combination. This species is excluded from Amiserica based on its characteristic genital morphology (Kobayashi 1991: Fig. 7 a – c). The species group assignment of the other included species is rather complicated. Amiserica shizumui Kobayashi, 1980 (see Ahrens 2002) and Amiserica babai Kobayashi, 1988 lack the membraneous sacs of parameres. However, in the first species, the metatibia also possesses a long serrated line beside the dorsal margin and a serrated line close to the anterior margin of metafemur while the anterior margin is robustly margined. Possibly both species represent isolated lineages. We had no material available for Amiserica babai.	en	Ahrens, Dirk, Liu, Wangang, Pham, Phu Van, Fabrizi, Silvia (2021): An overview on the genus Amiserica Nomura, 1974 (Coleoptera: Scarabaeidae: Melolonthinae: Sericini).

03DC87BEE115FFBFFF7FFCF09C66F085.taxon	discussion	Remarks. Given on the vast variation of genital and antennal morhology represented in the species examined here, we came to the conclusions, that the doubtful Lasioserica Brenske, 1896 species, Lasioserica antennalis Nomura, 1974, is in fact supposedly closely related to Amiserica rufidula Nomura, 1974, in contrast to the other Lasioserica species including its type, Lasioserica nobilis (Brenske, 1894) (see material examined in Ahrens 2002). Interestingly, the state of a 4 - lamellate antennal club is common in more species, that the condition of the type species, A. rufidula, having a 3 - lamellate club. Consequently, we consider the former to be a member of Amiserica: Amiserica antennalis (Nomura, 1974), new combination.	en	Ahrens, Dirk, Liu, Wangang, Pham, Phu Van, Fabrizi, Silvia (2021): An overview on the genus Amiserica Nomura, 1974 (Coleoptera: Scarabaeidae: Melolonthinae: Sericini).

Amiserica fengyangensis Ahrens, Fabrizi & Liu, new species differs from A. incisa, with which A. fengyangensis shares the subparallel left paramere by the short and curved narrowed portion of left phallobasal dorsolateral apical process, which is much less than half as long as the process itself. The subparallel left paramere distinguishes both species from the similar A. funiushanica Ahrens, Fabrizi & Liu, new species.	en	Ahrens, Dirk, Liu, Wangang, Pham, Phu Van, Fabrizi, Silvia (2021): An overview on the genus Amiserica Nomura, 1974 (Coleoptera: Scarabaeidae: Melolonthinae: Sericini).
