A New Species of Eurygaster and Notes on Some Little Known Species of Turkish Pentatomidae (Hemiptera: Heteroptera)

The species belonging to the genus Eurygaster Laporte are veryimportant from the economic point of view in Turkey. Eurygasterintegriceps Puton is one of the most harmful insects to wheat andbarley, but in addition it also attacks rye, oat and other graminaceousplants. In Turkey it causes extensive damage especially in the easternsouth provinces, the amount of injury caused varying from year toyear and from place to place. In epidemic years the total amount ofthe losses in some areas can reach up to 9o% if no control measuresare used. Eurygaster maura (L.) and Eurygaster austriaca (Schrk.),found especially in Western Anatolia, cause damage approaching only20% if no control measures are used, because their egg parasites arevery active in this part of the country. A good knowledge of thisgenus is therefore very important to Turkish entomologists and agriculturists.While working at the University of Aegea, Izmir-Turkey,I paid speciaL attention to these insects and collected many specimenswhenever time was available. Amongst my material I find one newspecies which is described below
