Melanomaladera Miyake & Yamaya, 2001 : 38, new synonymy ( type species Melanomaladera yunnana Miyake & Yamaya, 2001 by original designation). Remarks. The genitalia of Melanomaladera yunnana Miyake & Yamaya, 2001 is very similar to that of A. medvedevi Nikolajev, 1982 . The black and shiny body, the bordered base of the pronotum, and a dorsal or lateral apophysis of the phallobase are diagnostic characteristics of the species of Archeohomaloplia . The number of antennal segments in the type species; Archeohomaloplia potanini Nikolajev, 1982 ; varies between nine and ten. Since Melanomaladera have all the diagnostic characters of Archeohomaloplia , it should be regarded as a junior synonym of the latter.
