A New Genus and Species of Orsillinae (Heteroptera: Lygaeoidea: Lygaeidae) from Argentina

Abstract

The new genus and species Cuyonysius flavidus, n. gen. and n. sp. (Hemiptera: Heteroptera: Lygaeidae: Orsillinae), described from San Juan Province, Argentina, is tentatively placed in the orsilline tribe Metrargini, based on the lack of a dorsal lobe on the conjunctiva, punctures along the claval suture, and the punctate buccula. Color digital images of the adult male and female, the pygophore, parameres, and aedeagus are provided to help distinguish this new metrargine from closely related taxa. A color habitus image and new distribution records are given for Balionysius maculatus Ashlock.
