Remarks (summarised from literature). Live specimens are reddish in colour and measure between 0.9 and 1 mm. The caudal body end is provided with an annulated tail. The proboscis has a total length of ~42 μm, with proboscis hooks measuring 22–23 μm and tongues measuring ~20 μm. The hooks consist of a straight proximal part, ~12 μm long and bearing a small denticle, followed by a branched, distal part, consisting of three finger-like spines (10–11 μm long). Proboscis sidepieces were not reported. The copulatory apparatus consists of an ovoid copulatory bulb into which a pair of seminal vesicles enter proximally. The bulb contains a 27-µm-long cirrus armed with fine spines. The cirrus is cylindrical proximally and distally ends in a spherical region.
