Type series

  1. Habitus
    Body white/colourless (after preparation). Eyes present (also after preparation).

  2. Cuticle
    Cuticle
    smooth, but with two transverse rows of gibbosities in the caudo-dorsal part of the body (configuration II:2-2). In some individuals gibbosities are well defined whereas in others weakly developed and therefore difficult to identify. Legs without gibbosities.

  3. Buccal apparatus
    Mouth antero-ventral. Peribuccal lamellae and papulae absent. Bucco-pharyngeal apparatus of the Isohypsibius type. Oral cavity armature absent or not visible under PCM. Buccal tube without the ventral lamina and with a single delicate posterior bend (visible in lateral view only). Two rod-shaped macroplacoids in the pharyngeal bulb present. The first macroplacoid with a central constriction,  second with a subtle posterior constriction; macroplacoid length sequence: 2<1. Microplacoid and septulum absent.

  4. Legs and claws
    Claws of the Ramajendas type with extremely elongated and flexible primary branches of external claws. Primary branches of claws with thin, but well visible accessory points ending at the highest point of the primary branch. Smooth lunules present on all legs, but distinctly larger under external claws. A long thin transverse (sometimes sinusoidal in shape) cuticular bar is present under internal and external claws I-III. Additionally, a short thick longitudinal (often with irregular edges) bar is present near internal claws I-III.

  5. Eggs
    Eggs (3-7) smooth, deposited in exuvium.

  6. Remarks
    None.
