New distribution records and plant associations for Crophius scabrosus (Uhler, 1904) (Hemiptera: Lygaeoidea: Oxycarenidae)

[摘要] Previous distribution records and plant associations are reviewed for the little-known oxycarenid Crophius scabrosus (Uhler, 1904). Based on fieldwork in the western United States, Kansas and Wyoming are reported as new state records. Adults were found on diverse plants in Nebraska, including juniper (Juniperus; Cupressaceae), pine (Pinus; Pinaceae), and composites (Compositae = Asteraceae); they were common in crowns of bunchgrasses (Poaceae), especially Panicum virgatum and Schizachyrium scoparium. Despite extensive fieldwork, nymphs were not found; a mating pair was observed on P. virgatum. Host plants—those supporting nymphal development— remain unknown, but composites such as species of Artemisia are suggested as potential hosts.
