Generic diagnosis (after Moravec 2013). Rhabdochonidae . Medium sized nematodes. Pseudolabia rudimentary. Vestibule dilated to form well-defined funnel- or barrel-shaped prostom supported by longitudinal thickenings projecting anteriorly as teeth, variable in number. Deirids simple or bifurcate. Lateral alae present or absent. Oesophagus divided into anterior muscular portion and posterior glandular portion.

Males: many pre-cloacal and five to seven post-cloacal pairs of papillae; no caudal alae; spicules unequal and dissimilar; gubernaculum absent; tail conical, its tip rounded or with sharp point, rarely with several minute digital processes.

Females: amphidelphic; vulva about mid-body, tail tip rounded or with sharp point, sometimes with many spines, spikes or small mucronate points; eggs elliptical, embryonated, their shells smooth, filamented or with swellings (“formations”). Parasitic in intestine of fresh-water fishes.
