Pyropteron hispanicum ( Kallies, 1999)

18 exuviae– 12 males, 6 females ( Spain, Prov. Almeria, 1700 m, 1993–1999)

Length and width: 11.5–15.5 × 2–3 mm (average:13.5 × 2.65 mm)

Plate of head projection blade wide and rounded in front. Frons depressions distinctly wrinkled, frontally fre- quently ended by a transverse mound. Frontal depressions large and elongated. Frontal setae situated prior to level of lateral angles of frons in dorsal view (Fig. 1a). Head projection blade not distinctly curved in lateral view, dark margin narrow. Frons rises at a slight angle from projection blade. Lateral depression on head wide and rounded ventro-caudally ventrocaudally (Fig. 1b). Distance between clypeal setae Cl 2 approximately 2.5 × greater than distance of C1 2 from Cl 1. Mandibles wide, elongated, labrum large truncated at end and with straight sides (Fig. 1c). Cremaster long, relatively roundly pointed at end, anal suture distinctly shorter than cremaster in male. In female cremaster approximately equal in length to anal suture. Spines on the 10th abdominal segment relatively robust, semicircular, their setae short (Fig. 1d). 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 hispanicum and P. maroccanum are very similar. Spines on the 10th abdominal segment more rounded, semicircular in Pyropteron hispanicum . In P. maroccanum , the spines are sharply pointed, triangular.

Biology. Host plants– Rumex spp., Rumex tingitanus L., Rumex scutatus L.

Distribution. Spain, Portugal and southern France ( Laštůvka & Laštůvka 2001; Corley, 2005).
