Description of a new desert-ant belonging to the Cataglyphis cursor group (Hymenoptera: Formicidae) from the Iberian Peninsula
The species of the Cataglyphis cursor group in Western Europe are reviewed, with particular attention paid to material from the Iberian Peninsula. Cataglyphis cursor (Fonscolombe, 1846) is found east of the Rhône River. Cataglyphis piliscapa (Forel, 1901) is relegated to the area from northeastern S...

| Sumario: | The species of the Cataglyphis cursor group in Western Europe are reviewed, with particular attention paid to material from the Iberian Peninsula. Cataglyphis cursor (Fonscolombe, 1846) is found east of the Rhône River. Cataglyphis piliscapa (Forel, 1901) is relegated to the area from northeastern Spain (Catalonia) to the Rhône River. The remaining Iberian material studied (largely originating from central Spain) belongs to a new endemic species, Cataglyphis mater sp. nov. García, Cuesta-Segura, Espadaler, Vila & Menchetti, which differs morphologically, genetically, ethologically, and geographically from the former. Morphometric analyses that include the removal of allometric variance, a principal components analysis, linear discriminant analysis and Ward cluster analysis, DNA barcoding and the
morphology of the genitalia have been used in order to establish the status of the central Iberian populations as new species. Diagnosis of the new species, with respect to C. cursor and C. piliscapa, includes an almost hairless cephalic underside and a larger head in workers, as well as very characteristic external genitalia in males. This new species is especially abundant on the northern plateau of Spain, appearing sporadically in other areas of the peninsula, showing an allopatric distribution with respect to the other species in the C. cursor group. In total, it has been collected in 125 localities across fourteen provinces, at an elevational range of 610 to 1922 m a.s.l . It was extensively found in sympatry with Cataglyphis iberica (Emery, 1906), another species with similar ecological requirements but belonging to the C. albicans group. With C. mater sp. nov., 11 Cataglyphis Foerster, 1850 species are known to occur in the Iberian Peninsula, being all but one (C. piliscapa), Iberian endemic. |
