Anthia fornasinii is a striking member of the subfamily Anthiinae, a group of large, fast‑moving predatory ground beetles known for their bold defensive chemistry. First described by Bertoloni in 1845, this species is native to Central and East Africa, where it roams open, arid landscapes in search of prey. Its body is heavily sculpted, with a characteristic ribbed abdomen noted by keepers and sellers alike, giving it a rugged, armoured appearance that suits its active, combative lifestyle.
 
Like other Anthia species, A. fornasinii is a formidable hunter, feeding on a wide range of invertebrates and relying on speed, strong mandibles, and a potent chemical spray to subdue threats. When disturbed, it can eject a jet of formic acid—a highly effective deterrent against predators and a behaviour that has made the genus famous among entomologists and hobbyists. Its size, typically around 5–6 cm in legspan, combined with its glossy black body and ribbed texture, makes it one of the more visually distinctive Anthia species encountered in the hobby.
 
In captivity, Anthia fornasinii is valued for its bold presence and energetic behaviour, though it requires warm, dry conditions that mimic its natural habitat. Its solitary, territorial nature means it must be housed individually, but when provided with space, structure, and a varied insect diet, it becomes a hardy and fascinating display species. The combination of its African origins, unique morphology, and dramatic defensive abilities makes A. fornasinii a standout beetle for enthusiasts seeking something both charismatic and scientifically intriguing
