Abstract
One new species of flower bug, Scoloposcelis koreanus Jung & Yamada, sp. nov., that inhabits shiitake mushroom farms, is described from Gangwon-do Province, South Korea. Diagnosis, description and biological notes of the new species are presented, along with a key to the species of Scolopocelis from the Palaearctic Region. Scoloposcelis Fieber, 1864 is a small genus in the tribe Scolopini (Hemiptera: Heteroptera: Anthocoridae). As other flower bugs that prey on small arthropods, their predaceous habits of Scoloposcelis have attracted the attention of researchers who work in forest-ecosystems (Lattin 1999), especially as the predators of bark beetles and other tiny arthropods that occur under or between the barks of conifers or deciduous trees (cf.,Carayon 1954a, 1956; Mura-leedharan & Ananthakrishnan 1974; Pericart 1996; Yamada & Hirowatari 2005). The genus is characterized by the body being elongated, flattened, and parallel-sided, the femur usually spinulate on the ventral surface, and the ura-denia having an ampulla, a unique glandular opening on the male abdominal sternum IV (Carayon 1954b).
