About Exosoma lusitanicum (Linnaeus, 1767)
Exosoma lusitanicum, first described by Linnaeus in 1767, reaches a body length of 6–8 millimetres, or 0.24–0.31 inches. These small beetles have elongated, oval, hairless bodies. Their pronotum is convex, wider than it is long, and marked with very fine punctures. Their elytra are tight-fitting and also finely punctured. The basic colour of both the pronotum and elytra is a shiny red-orange, while the head, antennae, legs, and abdomen are all black. This species is similar in appearance to Exosoma theryi. It is a quite common species, distributed across France, Italy, Spain, Portugal, North Africa (including Morocco, Algeria, and Tunisia), and the Near East. These beetles live in warm, dry areas, and can be found both in lowland plains and at elevations up to 1000 metres.
