Type series

  1. Habitus
    Body pale yellow, eyes present in all live and mounted animals.

  2. Cuticle
    Smooth, without sculpture or gibbosities.

  3. Buccal apparatus
    Bucco-pharyngeal apparatus of the Macrobiotus type, with ventral lamina and ten peribuccal lamellae. Oral cavity armature absent or not visible under PCM. Pharyngeal bulb spherical with two rod-shaped macroplacoids. Microplacoid absent. Macroplacoid length sequence 2<1. The first macroplacoid with a central constriction and with central and subterminal projections. The second macroplacoid with a subterminal constriction and projection.

  4. Legs and claws
    Claws of the Dactylobiotus type, with very short basal portions, similar in size and shape on all legs. Primary branches of claws with well developed accessory points. Lunules absent, but a robust semilunar cuticular connection between external and internal claws is present. Claws on the first three pairs of legs almost identical in length but on hind legs evidently longer.

  5. Eggs
    Spherical or slightly oval, white, laid freely. Ornamented, without areolation, with 41–46 processes on the circumference. Processes in the shape of short and wide cones (base diameter is greater than a half of the height). The majority of processes have a single sharp tip, however, some processes are bifurcated. The processes are smooth, but the surface between them is covered with a very delicate reticulation that connects the processes.

  6. Remarks
    None.
