3. Heteronybelinia sp. C ( Fig. 10 )

Material examined: plerocercoid from Sufflamen fraenatus (Latreille, 1804) , New Caledonia, MNHN JNC 3034.

Scolex length 1440, pars bothrialis 770, pars vaginalis 680, bulbs elongate, bulb length 375, velum 125, metabasal hooks on antibothrial surface: length 17–19, base 8; on bothrial surface: length 25, base 18; basal armature heteromorphous.

Remarks

This specimen clearly belongs to Heteronybelinia as the hooks differ markedly in shape on the bothrial versus the antibothrial surfaces of the tentacle. Hook sizes are closest to H. eureia (Dollfus, 1960) , but the specimen differs from this species in the number of hooks per half spiral and by the fact that in this specimen the bulbs are entirely posterior to the pars bothrialis while in H. eureia , they do not extend beyond the pars bothrialis. Therefore, this specimen cannot be accommodated within any known species of Heteronybelinia .
