Weston Opitz Kansas Wesleyan University Department of Biology 100 East Claflin Salina, Kansas 67401 Abstract: The subfamily El)iphloeinaeisdefined to include fourteen genera asfollows: Epiphloeus Spinola; Pilosirus, new genus; Plocanlocera Spinola; Ioritoclerus, new genus; Arenaria, new genus; Ichriea Laporte; Diaprorrieces, new genus; Pyticeroides Icuwert; Ellipotonla Spinola; Iiatarrty~~rus,new genus; Megatracliys, new genus; Mador~iellaPic; Hapsidopteris, new genus; and Teutonia, new genus. The following type-species are described: Pilosirus brur~oi,new species; Areriaria chiapas, new species; Diaprorrieces aclydis, new species; KatarriyuruspaxilLt~s, new species; Megatrcrcl~yspar~icnlrrs, new species; Hupsidopteris diastertus, new species; and Teutoriia rloua, new species.
