摘要
A new two-pored Amphisbaena is described from Formosa and Corrientes provinces of Argentina. The new species has a faint autotomy annulus (with a fracture plane) and two cicatricial precloacal pores separated medially by a pair of nonpored segments: It differs from Amphisbaena dubia, which has a pair of pores on adjacent segments and a fracture plane on the tail, and from Amphisbaena darwini heterozonata, which differs in pore number, coloration, and shape of the autotomy annulus.
