Head with three cephalic vesicles, each filled with symbiotic bacteria, the lateral vesicles are not fused. Dorsal mammilliform cuticular sculpture. The caudal ala has a small incision.

All leg sense organs are present, fourth leg sense organs are straight with a diminutive flagellum. Seven pairs of star-shaped unicellular epidermal glands with small cytoplasm rays; one pair belonging to the cephalic region, three pairs in the first trunk segment and one pair in the other trunk segments.

The holotypic female is in simplex stage, 120 µm long and 76 µm wide between leg pairs II and III (Fig. 6). Body ovoid with an anterior head which appears separated from the rest of the body by a furrow (Fig. 7A; SEM of

). Anteriorly the head is slightly curved with a complete halechiniscid set of 11 cephalic appendages and three cephalic vesicles, one frontal and two lateral, each filled with associated symbiotic bacteria. Two apparently unfused lateral vesicles surround the protruding mouth area, the buccal tube and the stylets. The frontal vesicle is also filled with symbiotic bacteria and is placed anteriorly around the median cirrus.

The 19 µm internal cirrus consists of a strong scapus with a composite flagellum divided into proximal and distal sections, each of the three parts are of comparable length. The 13 µm external cirrus is comprises a minor scapus and a simple flagellum. The 24 µm lateral cirrus shares its cirrophorus with the primary clavae (Fig. 6). From the cirrophorus the lateral cirrus continues in a strong scapus and a long undivided thread-like flagellum. All cephalic cirri are free and not imbedded in the small frontal ala (Figs 6 and 7B). An incision is located in the middle of the robust and short (25 µm long) primary clava; it extends from the joint cirrophorus in which a “van der Land’s organ” is clearly visible. The secondary buccal clavae are lying ventrally between the three cephalic vesicles and the mouth cone. Each secondary clava is located separately on each side of the mouth cone.</paragraph>

The anus is covered with two overlapping folds and a caudal minor fold giving it a characteristic wave-like appearance. The gonopore is located on a large ovoid papilla surrounded by a rosette of six myoepithelial cells typical of arthrotardigrades. The distance between gonopore and anus is 12 µm. The reproductive system consists of an ovary with a large ovum and six smaller oocytes. The two lateral cuticular seminal receptacles are visible at the level between leg pair III and IV, each consists of a large spheroid vesicle located dorsolaterally and an S-shaped genital duct, which ends in a ventro-caudal opening. The spheroid vesicle is filled with mature spermatozoa.</paragraph>

A short dorsal spur is present only on the internal claws whereas calcars are present in all claws. Strong hook-shaped peduncles are seen at the bases of the external digits in all leg pairs. The hook of the peduncle is partly located in the tarsus. Claw glands in each coxa contain visible claws for the next cuticle stage.

A total of seven pairs of unicellular epidermal glands are observed; one of the cephalic pairs is located anterio-dorsally close to the base of the median cirrus, the two other cephalic pairs form a row of four epidermal glands very close to or in the first trunk segment. The pairs in the three other trunk segments are located dorso-laterally. Usually the unicellular glands are highly refractive, but in moulting animals, as the
