First record of Orsillus depressus (Hemiptera: Lygaeidae: Orsillinae) from the New World and Southern Hemisphere

Abstract

The lygaeoid Orsillus depressus Dallas feeds on seeds of several species, mainly cypress. Since the end of the last century, it has extended its range from its native area in the Mediterranean Basin towards northeastern Europe and it is considered an invasive species. In the present work, the presence of O. depressus is reported for the first time from the New World and Southern Hemisphere. Host plants and distribution from central-southern Argentina are given. In addition, morphological characters that allow their identification are provided.
