Stenoderus suturalis, commonly known as the stinking longicorn, is a species of longhorn beetle found in southern parts of Australia, including Western Australia. Growing to about 20 mm, the legs, head and thorax are glossy black. The elytra is a coloured orange.
When threatened, the stinking longicorn will release a stinking fluid from glands near the eyes, located laterally near the mandibular articulations.
