  1. Habitus
    Body colour transparent/white, eyes present in 70% of specimens mounted in Hoyer's medium.

  2. Cuticle
    Except for all legs, where well visible granulation is present, cuticle is smooth, i.e. without gibbosities, papillae, pores, spines or sculpturing.

  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 composed of two posterior bands of teeth (similar on dorsal and ventral side). The first/anterior band of teeth is absent or not visible under PCM. The second band of teeth comprising small granules arranged in a few irregular rows that run around the oral cavity wall (PCM), is positioned at the rear of the oral cavity, between the ring fold and the third band of teeth. The third band of teeth is positioned just before the buccal tube opening and composed of large transverse ridges (PCM). In this band, three ventral and three dorsal teeth are present (two lateral and one median). The median tooth is sometimes divided into a few smaller teeth. Pharyngeal bulb spherical, with triangular apophyses and three rod-shaped macroplacoids. Macroplacoid length sequence 2<1<3. The first macroplacoid without constrictions but distinctly narrower anteriorly. The second macroplacoid of a uniform width and without constrictions. The third macroplacoid with a sub-terminal constriction. Microplacoid absent.

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

  5. Eggs
    Laid freely, white, spherical and ornamented. Processes in the shape of blunt or slightly sharpened cones. Labyrinthine layer between process walls is visible under PCM as a clear reticular pattern. Eggs shell areolated with a single ring of ten areolae around each process. Internal surface of areolae smooth and without pores.

  6. Remarks
    None.
