Syncosmetus reticulatus Miyatake, 1985 ( Figs 7 , 139–141 , 142B, 143B , 145 )

Diagnosis and comments

The species differs from Syn. japonicus by the more parallel-sided body ( Figs 139–141 ) and less marked keels on elytra. No males were examined, so it was not possible to evaluate whether some of the distinct characters of the male genitalia of Syn. japonicus are restricted to the species or diagnostic of the genus.
