Fig. 1 – Sampling locations overlaying summer precipitation
across Spain, with gradient from dry Mediterranean to wet Atlantic.
Ovals encompass the two allopatric regions (Granada and Jaen forM. escalerai and northern Cantabria for M. crypticus ). The
rectangle encompasses the sympatric region (La Rioja and the
Mediterranean climatic zone at the south of Cantabria). Insert shows the
sympatric region with locally sympatric (red) versus locally allopatric
(blue and orange) locations. Black star on the sympatric location at the
E side of the main map in Catalunya denotes a swarming site and was
excluded from the analysis.
