Pyropteron aistleitneri (Špatenka, 1992)  

( Figs 17 View FIGURES 11–18 , 19 View FIGURES 19–26 , 129–131 View FIGURES 120–134 )

Synansphecia aistleitneri Špatenka 1992   : Alexanor. Revue des lépidoptéristes français, 17 (7): 436, 437 Fig. 5 View FIGURES 3–10 , 445 Figs 14–15 View FIGURES 11–18 . Holotype: ♀, Spain, Prov. Granada, Sierra de Guillimona (ZSM).

This and the following species are close related. Despite the small difference in the DNA barcodes of an average less than 2%, both species seem well separated by external appearance and local distribution. Although both species utilize the same hostplant, they are limited to different altitudes. In the Sierra Nevada, P. aistleitneri   occurs in direct proximity (6 km) to P. kautzi   , but it remains limited to a much lower altitude (pers. observations Lingenhöle, Pühringer).

Diagnosis. In P. aistleitneri   , the body is black with white markings, labial palps dorsally and ventrally densely suffused with white; especially frons, pericephalic scales and fore coxa laterally white; tegula caudally white; a white lateral spot on the meso-thorax below the forewing; a white lateral patch on mid- and hind tibia; abdominal tergites 2, 4 and 6 with white narrow caudal margins. In P. kautzi   , the body, including labial palps, frons, lateral part of meso-thorax and entire fore coxa, is dark bronze-brown; pericephalic scales, tegula caudally and a lateral patch of mid- and hind tibia ochre-yellow; caudal margins of abdominal tergites 2, 4 and 6 yellowish. One specimen of P. aistleitneri   from Sierra Nevada (2200 m) has the usually white markings pale yellow as P. kautzi   , but is otherwise typical. Its location is just 6 km (airline distance) from the nearest P. kautzi   -biotope (2870 m).

Variability. One specimen of P. aistleitneri   from the Sierra Nevada (2200 m) has the usually white markings pale yellow as in P. kautzi   , but is otherwise typical. Its location is just 6 km from the nearest P. kautzi   habitat (2870 m).

Barcodes. Despite the considerable external differences, this species differs from its sister, P. kautzi   , by only 2.0% in the barcode. A very homogenous species with intraspecific barcode differences of less than 0.2%.

Biology and habitat. The host plants are perennial Erodium spp.   such as the closely related E. cheilanthifolium Boissier   , E. glandulosum Cavanilles   and E. saxatile Paul   ( Geraniaceae   ) ( Pühringer & Pöll 2004a, pers. observation Laštůvka; Manceñido in litt. 2015). The latter is concluded from the sole occurence of E. saxatile   (= E. valentinum (Lange) Greuter & Burdet   ) in Sierra de Maria and Sra de Espuña, where P. aistleitneri   has been detected recently (pers. observation Pühringer & Pöll). The species occurs in dry and stony places on mountain slopes and in the summit areas of mountain ranges in altitudes of 1350–2200 m. It seems confined to lime stone or dolomite, whereas P. kautzi   lives on crystalline floor.

Distribution. Endemic to mountain ranges of northern, central and southern Spain ( Laštůvka & Laštůvka 1995, 2001, Pühringer & Pöll 2004 a, González-Estébanez & Manceñido-González 2012, pers. observation Pühringer & Pöll 2018).
