Revision of the Myodochini (Hemiptera : Lygaeidae : Rhyparochrominae) of the Australian region

Abstract

The following new genera and species are described: Exopamerana, gen. nov. (type-species E. misimensis, sp. nov.); Henicorthaea, gen. nov. (type-species H. yeoi, sp. nov.); Horridipamera, gen. nov. (type-species Plociomerus nietneri Dohrn, 1860), H. cantrelli, sp. nov., H. robusta, sp. nov.; Myodorthaea, gen. nov. (type-species M. monteithi, sp. nov.); Pachybrachius robustus, sp. nov.; Pamerana fulvomaculata, sp. nov.; Pamerapa, gen. nov. (type-species Pamera thoracica Distant, 1901), P. pilosa, sp. nov.; Pamerarma, gen. nov. (type-species Orthaea ventralis China, 19301, P. necventralis, sp. nov.; Paraeucosmetus, gen. nov. (type-species Rhyparochromus pallicornis Dallas, 1852), P. leaorum, sp. nov., P. novaeguineae, sp. nov., P. pacificus, sp. nov., P. papuaguineae, sp. nov., P. perkinsi, sp. nov., P. woodwardi, sp. nov.; Pseudopachybrachius, gen. nov. (type-species Rhyparochromus gutta Dallas, 1852); Paromius australis, sp. nov.; Stigmatonorum minutum, sp. nov.; Woodwardocoris, gen. nov. (type-species W. queenskzndicus, sp. nov.). The following new synonymies are made: Remaudiereana Hoberlandt, 1954 with Pachybrachius Hahn, 1826; Pachybrachius palauensis Barber, 1958 with Pachybrachius inornatus (Walker, 1872); Paromius pallidus (Montrouzier, 1865) with Paromius gracilis (Rambur, 1839). In addition to those noted above, the following new combinations are made (the most recent generic placement in parentheses): Pamera insignis Distant, 1901 (Pachybrachius) to Paraeucosmetus, P. murrhea Distant, 1901 (Pachybrachius) to Pamerapa, P. sobrina Distant, 1901 (Remaudiereana) to Pachybrachius, Rhyparochromus cincticornis Walker, 1872 (Pachybrachius) to Paraeucosmetus, R. inornatus Walker, 1872 (Remaudiereana) to Pachybrachius. In addition to the previously described genera and species noted above, the following are redescribed: Altomarus Distant, 1903, A. greeni Distant, 1903; Pachybrachius Hahn, 1826, P. puberulus (China, 1930); Pamerana Distant, 1909, P. nigritula (Walker, 1872); Paromius Fieber, 1860; Stigmatonotum Lindberg, 1927, S. cephalotes (Kiritshenko, 1931); Suffenus Distant, 1904, S. fusconervosus (Motshulsky, 1863). The genera and species of the Myodochini of the Australian region are keyed and the taxonomically important structures discussed. Dorsal views of the body and line drawings of genitalia and other structures of systematic importance are presented.
