On the South American species of the genus Meridiosignum (Crustacea: Isopoda: Asellota: Paramunnidae)
Meridiosignum undulatum n. sp. and M. disparitergum n. sp. are described from off the Río de la Plata estuary. These two new species are easily distinguished from other members of the genus Meridiosignum in having the lateral margins of pereonites 2 and 3 bilobed (the concavity is much more pronounc...
