Description

Diagnosis. Claws of the Isohypsibius type (Fig. 2 E); double claws of the same leg slightly different in shape and size; rigid buccal tube without ventral lamina but with a dorsal and a ventral apophysis for the insertion of the stylet muscles in shape of long, continuous ridges tailing off caudally and almost reaching the level of the stylet supports (Fig. 2 A, B, C); anterior portion of both apophyses with caudal processes pointing backwards and sideways (Fig. 2 C). At about a quarter the length of the ridged apophyses is an incision and septum (Fig. 2 A, B). Six peribuccal lobes present; peribuccal lamellae absent; structures in the form of peribuccal papulae present (Fig. 2 D), but this should be confirmed. Stylet furcae typically shaped, i. e. the basal portion of the two caudal branches are enlarged with thickened, swollen, and rounded apices (Fig. 2 B); pharyngeal bulb with apophyses and placoids (Fig. 2 C). Lunules present in the monotypic species (Fig. 2 E). Smooth eggs laid in the exuvium.
