We present the first formal record of the twig-girdler Psyllotoxus griseocinctus Thomson, 1868 (Cerambycidae: Lamiinae: Onciderini) attacking the rose, Rosa sp. (Rosaceae) in Southern Brazil. We provide photographs of the damage P. griseocinctus causes to the plant, as well as morphological descriptions of the immature stages and molecular diagnostic tools to identify this species. Additionally, we provide a modelled map with the known and potential distribution of P. griseocinctus and new host records for three plant species: the common walnut tree, Juglans regia L. (Juglandaceae); the cambucá tree, Plinia edulis (Vell.) Sobral (Myrtaceae); and the cherry tree, Prunus cf. serrulata Lindl. (Rosaceae).
我们首次正式记录到枝小蠹科 Psyllotoxus griseocinctus Thomson, 1868（鞘翅目：叶甲科：象甲亚科）在巴西南部攻击玫瑰，Rosa sp.（蔷薇科）。我们提供了 P. griseocinctus 对植物造成的损害的照片，以及未成熟阶段的形态描述和用于鉴定该物种的分子诊断工具。此外，我们还提供了一张建模地图，显示了 P. griseocinctus 的已知和潜在分布范围，以及三种植物的新寄主记录：普通核桃树，Juglans regia L.（胡桃科）；坎布卡树，Plinia edulis（Vell.）Sobral（桃金娘科）；和樱桃树，Prunus cf. serrulata Lindl.（蔷薇科）。
