1. Habitus
   Body white/colourless. Eyes absent in 18% of specimens mounted in Hoyer’s medium.

2. Cuticle
   Entire cuticle covered with small (0.4–1.1 µm) and large (1.9–2.5 µm) round or oval pores. Pores arranged in 9-10 poorly defined transverse bands. Pores on the dorsal cuticle arranged more densely than on the ventral cuticle. A single large pore (2.1-2.9 µm) present on external side of legs I-III. A ring of pores around the mouth opening absent. Cuticle without granulation, except for legs which are all covered with fine and regular granulation (better developed on legs IV) visible only in larger specimens.

3. Buccal apparatus
   Mouth antero-ventral. Ten peribuccal papulae present. Bucco-pharyngeal apparatus of the Minibiotus type. Oral cavity armature absent or not visible under PCM. Buccal tube with a poorly visible ventral lamina and with an anterior and a posterior bend (both visible in lateral view only). Buccal tube walls thickened just below the stylet supports insertion point. Pharyngeal apophyses triangular, very near to the first macroplacoid. Three granular macroplacoids and a minute microplacoid present in the pharyngeal bulb. All macroplacoids of similar but not identical sizes, the macroplacoid length sequence: 2<1<3. Septulum absent.

4. Legs and claws
   All legs with fine granulation. Claws of the Macrobiotus type. Primary branches of claws with thin, but obvious accessory points detaching at the apogee of the primary branch curve. Smooth lunules present on all legs, distinctly larger under external and posterior claws. Bars and other cuticular thickenings on legs absent.

5. Eggs
   White/transparent, laid freely, spherical, without areolation. Processes in the shape of short, smooth, slightly flexible cones. Processes distributed on the surface of the egg close one to another but never in contact. Surface between processes smooth under PCM.

6. Remarks
   None.
