Revision of the Phthia generic complex with a description of four new genera (Hemiptera: Heteroptera: Coreidae: Coreinae: Leptoscelini).

The Neotropical genus Phthia Stål, 1862 in its current wide concept is revised and divided into five genera: Phthia s. str., Phthiacnemia gen. nov., Phthiadema gen. nov., Phthiarella gen. nov., and Rhytidophthia gen. nov. The following nine new combinations (all from Phthia) are proposed: Phthiacnemia picta (Drury, 1770), comb. nov.; Phthiadema cyanea (Signoret, 1862), comb. nov., Ph. ornata (Stål, 1865), comb. nov., and Ph. smaragdina (Walker, 1871), comb. nov.; Phthiarella affinis (Distant, 1901), comb. nov., Ph. decorata (Stål, 1865), comb. nov., Ph. femorata (Breddin, 1901), comb. nov., and Ph. sponsa (Breddin, 1901), comb. nov.; and Rhytidophthia splendida (Valdés, 1910), comb. nov.
