Lamellocepheus personatus ( Berlese, 1910)

Description ( Figures 1-4 )

Length: 280-290 µm, width: 160-164 µm (n =2).

Prodorsum with coarsely granulated cerotegument. Rostrum incised in the middle. Rostral, lamellar and interlamellar setae short and smooth. Lamellae long, straight, originate in front of the bothridia and without translamella. Sensilli leaf-shaped, barbed, about 30 µm in length. Bothridium opening anteriorly.

Dorsosejugal suture slightly protruding in the middle. Ten pairs of short and smooth marginal notogastral setae present. Two pairs of them c 2 and la arising on small tubercles. In the anterior middle region of the notogaster, a wide depression present. Notogastral cuticle covered by coarsely granulated cerotegument.

Epimeral setal formula: 3-1-3-2. On both sides of the genital plates with longitudinal ridges. Genital and anal plates are approximately the same length and width (35 µm) and the distance between them is 14 µm. Five pairs of genital, one pair of aggenital, two pairs of anal and two pairs of adanal setae present. Lyrifissures iad situated paraanally. All legs monodactylous.
