nothing iso... as far as I know. I would just call them the

  non-centrosymmetric primitive orthorhombic   super-group

(or simply the  "primitive orthorhombics"  if you are in the
 biomacro business and can neglect the centric ones)

or, after consulting the "Tables", the

  primitive   sub-group   of the
  orthorhombic hemihedral-holoaxial   crystal class
