First Record of the Genus Stirocorsia (Orussidae: Hymenoptera) from Korea

Abstract

The family Orussidae is a unique parasitoid group belonging to the suborder Symphyta. Members of Orussidae are rare and only a species, Orussus coreanus Takeuchi have been previously recorded from Korea. In this study, we report another species, Stirocorsia tosensis (Tosawa and Sugihara, 1934), for the first time from Korea. The adult characteristics of the species with illustrations and a species key to the Korean Orussidae are provided.

New records of Orussus minutus Middlekauff, 1983 (Hymenoptera: Orussidae) represent a significant western range expansion

“…Additionally, new species continue to be described, even in heavily collected areas such as California (e.g., Vilhelmsen 2005, Blank et al 2010, Vilhelmsen et al 2014). Several species are known only from one or a few localities and specimens and the known ranges of many species continue to expand as new specimens are collected (Ahnlund and Ronquist 2001, Vilhelmsen and Smith 2002, Pesarini and Turrisi 2003, Pesarini and Turrisi 2006, Choi and Suh 2011). …”
