Pyropteron maroccanum ( Kallies, 1999)

13 exuviae– 9 males, 4 females ( Morocco, High Atlas Mts , 1996–2001) Length and width: 11.5–15 × 2.5–3.5 mm (average: 13.4 × 2.85 mm). FIG. 2. Morphology of Pyropteron maroccanum a. Dorsal view of frons, b. Lateral view of frons, c. Labrum and vicinity, d. Ventral abdominal end (male). Scale bar– 0.2 mm .

Area of head projection blade short and fairly sharply rounded in dorsal view, its length is slightly shorter than half of its width. Frontal setae situated prior to level of lateral angles of frons in dorsal view. Depressions of frons wrinkled, fairly deep and frons central ridge strong (Fig. 2a). Plate of head projection blade not curved in lateral view. Dark margin narrow. Frons rises gently from its projection blade in lateral view. Lateral depression on head relatively narrow, elongated and caudoventrally concave (Fig. 2b). Distance between clypeal setae C1 2 approximately 2.5 to 3 × greater than distance between C1 2 and Cl 1. Labrum truncate for a greater distance and with straight or slightly convex sides (Fig. 2c). Cremaster relatively round at end, anal suture distinctly shorter than cremaster in male, approximately equal in length to anal suture in female. Spines on the 10th abdominal segment robust, trian- gular, sharply pointed, their setae short (Fig. 2d). Spines of basal row on the 2nd abdominal segment absent. Spines of caudal row approximately 2 × smaller than those of basal row on the 3rd abdominal segment. The 4th abdominal segment bears 10–11 slender spines of basal row between setae D1.

Diagnosis. The pupae of Pyropteron maroccanum and P. hispanicum are very similar. Spines on the 10th abdominal segment of P. maroccanum are triangular, sharply pointed.

Biology. The host plant is an unidentified species of Rumex similar to R. acetosa L. ( Kallies 1999).

Distribution. Morocco, High and Middle Atlas Mts., collected at elevations between 1650–2700 m ( Kallies 1999).
