Interpretive Summary: Seed bugs represent a relatively large worldwide group of bugs that feed on seeds still attached to plants or those that have fallen to the ground. Most seed bugs are of little economic importance, although some may become nuisance pests when large numbers are attracted to light and often invade homes. One other group of seed bugs, often called false chinch bugs, however, may become of importance when large populations move from wild hosts to agricultural crops. The new genus and species described in this publication is related to the false chinch bugs. Dorsal images of the adult male and female and other pertinent structures are provided to help distinguish this bug from closely related species and its relationship with other false chinch bugs is discussed. This paper will be of interest to taxonomists studying biodiversity and to crop specialists, especially those working in seed production.

Technical 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 genital capsule, 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.
