N= 3 specimens: 1 female, 1 male, 1 juvenile occurrence: ANDEEP-SYSTCO; 2,891 m bsl. Fig. 6; Supplementary Table 1.3

Short description

Large tardigrades (205–294 µm, n=2) of elongated body, with coelomocytes and other spherical cells. Secondary clavae have clearly visible ventral side shape as in original description (Fig. 6G, G 2). On the dorsal side the median cirrus is placed between the secondary clavae (Fig. 6F). Claws without heteromorphy. Accessory spines only on the internal claws of leg IV (Fig. 6H). Juvenile (205 µm) with internal claws and sometimes with external claws developing inside the femur (Fig. 6I). The female has a gonopore and seminal receptacles.

Remarks

C. tenellus is recognisable by the secondary clavae shape and median cirrus position. All representatives have accessory spines on each leg IV internal claw (Renaud-Mornant, 1974).
