Paramerina mauretanica

Author: Fittkau, 1962

Diagnosis (Material in coll. ZSM; in part after Fittkau, 1962a)
Exuviae 3.9-4.4mm long (n=4).
Colour: Light brown, thorax slightly darker; abdominal segments nearly as light as the conjunctives; (II)III-VI with dark crescent-shaped marks, in some specimens the crescent-tips reach the anterior segmental margin.
Cephalothorax: Thoracic horn 250-290µm long (n=5), with rounded basal tubercle; ThR 4.5-6.4 (n=5). Horn at most basally weakly pigmented; atrium dark to nearly black, neck light brown. Plastron plate only as wide as, or a little wider than its neck, 5x5-7x7µm; 0.11-0.16 maximum width rim; length 0.018-0.02x horn length (n=4). Maximum diameter rim 40-57µm (n=4). Atrium of thoracic horn thin-walled, 0.58-0.72x as wide as the horn lumen (n=5) (025h.jpg), joined to the plastron plate by a short straight neck. Thorax granulate. Thorax comb well-developed, composed of strong, more or less parallel-sided teeth.
Abdomen: Tergite I with a median mark. Segment VII transversely rectangular. Four lateral taeniae on segment VII. Anterior lateral taenia of segment VII at 0.3-0.34 of length segment VII (n=5), distance between first and second lateral taenia equal to distance between third and fourth. Anterior lateral taenia of segment VIII at 0.27-0.37 of length segment VIII (n=5).
Anal segment: Anal lobes without a thickened lateral edge. Anal lobes toothed externally only. Anal lobe ratio 2.5-3.1 (n=5). Insertion of anterior anal taenia not beyond 0.45 lobe length. Insertion of anterior anal taenia at 0.38-0.42 of lobe length (n=5).
