Halyomorpha halys (Stål, 1855)

There has been considerable confusion surrounding the systematics of this species. First, Distant (1880a, 1893e) considered this taxon to be a junior synonym of Halyomorpha picus (Fabricius). Later, it was determined that this species was different from H. picus, but various authors used either H. brevis (Walker) or H. remota (Walker) as the proper name. Josifov & Kerzher (1978) determined that there was only one species of Halyomorpha occurring in Japan, Korea, and eastern China, and that H. halys (Stål) actually had priority. The record of Halyomorpha picus from Egypt (Gadalla, 2004) probably is based on misidentified H. halys.
