Diagnosis. Species of Trioserica are identified by the following combination of characters: a tridentate anterior tibia (which distinguishes them from closely related Microserica and Tetraserica ), a distinctly carinate hypomeron, light, the pale color of body surface with numerous, more or less large dark spots, and the general morphology of the genitalia. The antenna is composed of ten antennomeres, the club has in male four antennomeres and is short, in female it has three antennomeres. Male genitalia have a shortened right paramere, which is inserted at the apex of the phallobase, and the dorsolaterally inserted left paramere, which is much longer than the right one.
