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.

Figures

FIGURE 4. Schematic representation of Harpagonchinae and Spilipherinae genera. The drawings aim to show head with buccal cavity and amphideal fovea and cuticle ornamentation (general pattern). For Harpagonchus, Harpagonchoides and Acantholaimus the copulatory apparatus is also presented. In all drawings the right side is the dorsal side of the nematode.
