Abstract: : A complete second-instar male larva of Nula sis gen. et sp.n., belonging to the cockroach family Blattulidae Vishniakova, 1982 is described from the Early Cenomanian amber of Sisteron in France. It reveals detailed and complete 3D morphology, with important presence of the central, 3rd ocellus, reduced in most adults and in all living cockroaches and termites, but present in some mantises. The modern distribution of unspecialized sensorial system of sensilla chaetica is also notable.
