Amiserica Nomura, 1974: 81 (type species by monotypy: Amiserica rufidula Nomura, 1974); Ahrens 2004 b: 126, 2007c: 11.
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).
Among Amiserica, we may distinguish the following species groups:
1 Apex of metatibia moderately deeply concavely truncate...................................................... 2
- Apex of metatibia deeply and sharply truncate. (Himalaya)......................... Amiserica costulata (Frey) group
2 Dorsal surface of body sparsely setose or nearly glabrous...................................................... 3
- Dorsal surface of body densely and erectly setose............................................................ 7
3 Dorsal surface of body sparsely setose and generally multi-coloured. (NE India, Indochina)................................................................................................ Amiserica insperata (Brenske) group
- Dorsal surface of body apart from minute setae in punctures and a few very single longer setae on sides of elytra glabrous and generally unicoloured.................................................................................. 4
4 Body surface dull. Each paramere with a membraneous sacculus at apex. Antennal club in male with 3 or 4 antennomeres. Antenna composed by 10 antennomeres. Metafemur with serrated line adjacent to anterior margin. (E-Asia).................................................................................... Amiserica rufidula (Nomura) group
- Body surface shiny. Parameres without a membraneous sacculus at apex. Antennal club in male with 3 antennomeres. Antenna composed by 9 antennomeres............................................................................ 5
5 Metafemur without serrated line adjacent to anterior margin. Posterior margins of metafemur serrated.................. 6
- Metafemur with serrated line adjacent to anterior margin. Posterior margins of metafemur smooth, not serrated........................................................................................... Amiserica gulinqin group
6 Phallobase with a narrow apical dorsomedian process. Parameres asymmetric and strongly bilobate. (China)......................................................................................... Amiserica guizhouensis group
- Phallobase without a narrow apical dorsomedian process. Parameres symmetric and simple, not bilobate. (China)..................................................................................... Amiserica venxianensis group
7 Parameres and phallobase strongly asymmetric. (China)................................... Amiserica jizuensis group
- Parameres and phallobase symmetric. (Himalaya)................................ Amiserica argentata (Frey) group
