Type series

  1. Habitus
    Body light yellow in living specimens and transparent after fixation in Hoyer's medium. Eyes present.

  2. Cuticle
    Except for well visible granulation present on all legs, cuticle is smooth, i.e. without gibbosities, papillae, spines or sculpturing but with well visible round and oval pores (0.5-1.0 µm in diameter), scattered randomly over the entire body (not arranged in bands or other patterns).

  3. Buccal apparatus
    Mouth antero-ventral. Bucco-pharyngeal apparatus of the Macrobiotus type, with the ventral lamina and ten peribuccal lamellae. The oral cavity armature with three bands of teeth (all visible only in SEM; under PCM only dorsal teeth of the third band are detectable). The first band of teeth are extremely small cones situated at the anterior portion of the oral cavity, just behind the base of the peribuccal lamellae. The second band of teeth are slightly larger cones, and positioned at the rear of the oral cavity, between the ring fold and the third band of teeth, which are two small, lateral teeth in the shape of granules, positioned at the rear, dorsal side of the oral cavity, just before the buccal tube opening. Ventral teeth of the third band absent or not visible in PCM.

  4. Legs and claws
    All legs with well visible granulation. Claws large, of the ariekammensis type. Primary branches with distinct accessory points. Lunules under claws on legs I-III smooth and distinctly dentate on legs IV. Thin cuticular bars under claws I-III present. Other cuticular structures on legs absent.

  5. Eggs
    Laid freely, very light yellow, spherical and ornamented. Processes in the shape of truncated cones without discs. In the apical parts of some processes from one to a few septa are visible in a mid-section. Surface between processes smooth, without areolation, pores or wrinkles.

  6. Remarks
    None.
