Revision of the genus Tibraca Stål (Heteroptera, Pentatomidae, Pentatominae)

Abstract

The genus Tibraca Stål, 1860 is revised, and some taxonomic changes are introduced. The following species are considered to belong in this genus: Tibraca limbaliventris Stål, 1860, T. similima Barber, 1941, and T. exigua sp.n. (from Argentina). Three other species, formerly placed in Tibraca, are considered respectively: T. obscurata Bergroth, 1914, incertae sedis; Mecocephala fusca (Haglund, 1868), comb.n.; Ogmocoris hypomelas (Burmeister, 1835). The genus Ogmocoris Mayr, 1864 is reinstated
