Genus Psallus sensu lato

Type species: Lygaeus sanguineus Fabricius, 1794, a synonym of Cimex haematodes Gmelin, 1790 (subsequent designation by Reuter, 1888: 412).

Remarks. Species of Psallus are usually 2.9−5.5 mm in length, with oval or elongate body and various coloration from yellow, or orange, or red, pale or dark brown, or black, sometimes variously spotted or mottled, and rarely tinged with green (Fig. 1). This is one of the largest genera in tribe Phylini, members of which are grouped into eight different subgenera. The species are distributed in temperate or cold temperate regions of the Northern Hemisphere. Recently, twenty six species of Psallus are revised from the Korean Peninsula including new species and first reports (Duwal et al., 2012). Herein, we would like to add descriptions of additional species from the Korean Peninsula; Psallus (Calopsallus) injensis Duwal sp. nov., P. (Halopasllus) taehwana Duwal sp. nov., P. (Phylidea) yongdaeri Duwal sp. nov.
