Genus Soronia Erichson, 1843

Soronia Erichson 1843: 277 . Type species: Silpha grisea Linnaeus, 1758 .

Platipidia Broun 1893: 1075 . Type species: Platipidia asperella Broun, 1893 .

Diagnosis. Medium sized, body more or less flat; pronotal and elytral margins widely expanded, pronotal surface with depressions and weak tubercles; elytra very feebly costate and its surface with irregular striped markings; epipleuron slightly wider than antennal club and moderately elevated laterally; antennal grooves strongly convergent posteriorly; mentum pentagonal with small process in center of anterior margin; tarsi simple, scarcely dilated. This genus is rather similar to Lobiopa Erichson, 1843 , but it can be distinguished from it by: eyes with setae; antennal grooves strongly convergent posteriorly; mentum transverse; elytra and pronotum costate and pronotum with depression.
