          Californidorus Robbins and Weiner, 1978
Placed in the Longidoridae by original authors but later transferred to Nordiidae by Jairajpuri (1982).  One feature that distinguishes Californidorus from the Longidoridae is that there is not an offset constriction between the anterior and enlarged poserior portion of the esophagus (Robbins, 1985)..
