Odontocepheus piramidalis   sp. n.

Measurements. - Length: 591-632 µm, width: 275-330 µm.

Prodorsum: Rostral setae arising on tubercles, directed backwards. Lamellae gradually widened anteriorly, with a concave cuspis, their surface foveolate. All setae thick and squamose (Fig. 77). In the interlamellar region a characteristic chitinous formation (Fig. 76) present, like that of the genus Berlesezetes   Mahunka, 1980. Sensillus (Fig. 78) directed outwards and backwards, its peduncle geniculate. Tutorium (Fig. 80) well developed, with long and strong spines, arranged in a longitudinal row.

Notogaster: Median, unpaired notogastral condyles present, it is well chitinized, much darker than the rest of the surface. All notogastral setae very long and strong, setae p are longer than the distance between them. Surface of these setae squamose or finely roughened. Surface of notogaster alveolate.

Coxisternal region: Epimeral setal formula: 3 —1—3— 3. Setae 1b, 3b, 4a and 4b very long and strong, directed forwards, or inwards, all strong, similar to notogastral setae. Setae 1a, 1c, 2a minute, setae 3c and 4c slightly dilate, their surface also squamose. Surface of epimeral region with tubercles or with pustules (Fig. 79).

Anogenital region: Surface of genital and anal plates irregularly foveolate, genital and aggenital setae setiform, adanal setae phylliform or similar to notogastral setae.

Legs: Setae p and u on tarsi of all legs long, with dilate end. Setae of genu II as shown in Fig. 81.

Type-material: Holotype (1200-HO-87): Tunisia, No. 49. About 2 km NW from Maktar, 3 April, 1977. Berlese- and Tardigrada-samples from barren sites on border of town: litter from base of Pinus pinsapo   and a pulvinate Composite plant. Leg. S. Mahunka. 2 paratypes: from the same sample. Holotype and 1 paratype (1200-PO-87) deposited in the HNHM, 1 paratype in MHNG.

Remarks: See in the remarks of the following new species.
