Generic diagnosis (after Margolis 1977). Cystidicolidae . Relatively large worms, tapering at both ends, cuticle transversely striated. Mouth dorso-ventrally elongated, surrounded by four submedian labia (two subdorsal and two subventral) and two narrow lateral pseudolabia; bilobed structure (sublabium), with thickened free margin, attached by its base to inner surface of each labium; pseudolabia continuous on inner margin with lateral anterior extensions of buccal cavity wall; these extensions terminating in two-pronged horn-like projections, prongs lying on either side of corresponding pseudolabium.of each projection. Four submedian cephalic papillae and two lateral amphids. Buccal cavity with thick cuticularized walls, sigmoid, longer than broad. Oesophagus divided into short anterior muscular and long posterior glandular portions. Nerve ring and excretory pore at level of muscular oesophagus. Caudal end of male spirally coiled, tip rounded, caudal alae present. Four pairs pre-cloacal and six pairs post-cloacal pedunculated papillae. Several longitudinal rows of pre-cloacal cuticular elevations. Spicules grossly unequal and dissimilar. Gubernaculum absent. Female tail with rounded tip. Amphidelphic. Vulva equatorial. Fully developed eggs thick shelled, with polar plugs and filaments at both poles, containing larvae when deposited.

Caballeronema wardlei , the type species, is known from two fish species in the Canadian Pacific.
