Malleusocoris, a new South American genus of Myodochini (Hemiptera, Rhyparochromidae) with modified antennae, along with some new synonymies and new combinations for misplaced taxa

Abstract

The new monotypic genus Malleusocoris is described to accommodate the new species M. minimussp. nov. from Argentina and Brazil. Its relationship with other genera of the tribe Myodochini (Hemiptera: Rhyparochromidae) is discussed. Moreover, the taxonomic allocation of Ptochiomera chilensis Spinola, 1852 and Plociomera annulicollis Berg, 1894 are discussed. Ptochiomera chilensis Spinola, 1852 is considered a junior synonym of Bergidia polychroma (Spinola, 1852) (Ozophorini); and Plociomera annulicollis Berg, 1894 is transferred to the genus Neopamera Harrington, 1980.
