Genus Harpagonchoides, Platonova & Potin, 1972

The genus Harpagonchoides (Figure 4) was established by Platonova & Potin (1972), who described H. crassus and initially established the family Harpagonchidae within Chromadorida . Lorenzen (1994) re-examined type specimens and lowered the rank of Harpagonchidae to the level of subfamily within Chromadoridae, particularly based on a single testis of males. All nematodes of this genus were collected from subantarctic and antarctic polychaete worms, between parapodia of Hemipodus digitifera Knox, 1960 (Glyceridae) .

Diagnosis (modified from Decraemer & Smol 2006 and Tchesunov 2014): Cuticle homogenous without lateral differentiation. Amphideal fovea unknown. Buccal cavity armed with three motile mandibles with hooks. Pharynx posteriorly terminated with a bulb. No preclocal supplementary organs.

Number of valid species: 1.
