Ankitokazoa bezanozanoi n. gen. n. sp. from the Olenekian (Lower Triassic) of Betsiaka (Ankitokazo Basin, Ambilobe district, northern Madagascar) is described as an annelid polychaete of the family Amphinomidae Savigny in Lamarck, 1818 on the basis of a single specimen. A taxonomic identification of the material examined is proposed thanks to the preservation of some soft parts: the eversible proboscis, the parapodia and, especially, the structure here interpreted as the caruncle, a nuchal sensory organ typical of the amphinomid polychaetes. The new taxon is compared with the other fossil polychaetes up to date described as representatives of the order Amphinomida Lamarck, 1818.
