Chamaesphecia borreyi Le Cerf, 1922: Études de Lépidoptérologie Comparée, 19 (1): 133. Lectotype: ♂, Moroccoeast, Chabat-el-Hamma (MNHN). Pyropteron atlantissensu Kallies, 1999(in part); nec Schwingenschuss, 1935, misidentification. This species is an endemic of the Atlas Mts in Morocco. It was revised by Kallies (1999)who also figured the male and female genitalia. It was thought to be confined to the Middle Atlas mountain range with larvae feeding in the roots of Limonium. Similar populations feeding in Armeriaand common at high altitudes of the High Atlas Mts were considered P. atlantis(compare Kallies 1999). Surprisingly, however, our barcode analysis and field observations have revealed that the populations associated with Armeriaalso belong to P. borreyi, while P. atlantisis confined to feeding on Helianthemum.
Diagnosis. P. borreyiis similar to several medium sized, dark brownish-grey to black coloured species of the genus, namely P. atlantis, P. maroccanaand P. erodiiphagafrom North Africa, and P. hispanica, P. koschwitziand P. kautzifrom south-western Europe. P. atlantisdiffers clearly by the glossy black (not dark grey to black) body, the pure white (not partly yellowish) markings, the deep black (not whitish mottled) abdomen. The remaining species differ by the more brownish base colour, the presence of a white patch between antenna and ocellus in male (present in males of P. maroccanaand P. hispanica). One specimen ( Fig. 99) from Mischliffen, Middle Atlas Mts, has the inner margins of the tegulae and the dorsal stripe of the abdomen white, very similar to P. atlantis, but the abdominal sternites are densely mottled with white (black in P. atlantis). Variability. This species shows a considerable degree of variability. Populations from higher altitude and feeding in Armeriashow somewhat smaller transparent areas of the forewings, wider discal spots and appear grey rather than brownish. Barcodes.Despite the small range inhabited by this species, sequence analysis shows some heterogeneity among P. borreyi, also reflected in the morphology, including the size of the transparent areas of the forewing. This is perhaps due to the wide range of habitats and hostplants, ranging from open, stony and bushy terrain with Armeriaas well as forest openings with Limoniumand Armeriain the Middle Atlas Mts to alpine meadows with exclusively Armeriain the High Atlas Mts. The maximal intraspecific sequence differences are at 1.5%, suggesting that all specimens examined are conspecific.
Biology and habitat. P. borreyiis an oligophagous species, whose larvae live in the root of various species of Limoniumand Armeria(Plumbaginaceae). It inhabits humid subalpine and alpine meadows between 1600 and 2900m, and often occurs together with the previous species.
