This crustacean is known from Pacific Mexico, the Gulf of California, and Nicaragua.
In adult females, the body is oval and distinctly longer than wide.
It parasitizes the gills of four mud shrimp species: Upogebia dawsoni, Upogebia spinigera, Upogebia macginitieorum and Pomatogebia rugosa.
In adult females, the head is slightly wider in front than behind, deeply embedded in the first thoracic segment, and has eyes.
In adult females, the lower abdomen has many ridges, and its appendages are two-branched and lance-shaped, with small marginal tubercles.
