Taxonomic and nomenclatural reassessment of the Iberian Peninsula's , Dufour, 1820 and L. Koch in Rosenhauer, 1856 (Chilopoda, Scolopendromorpha, Scolopendridae).

The taxonomic identities of the two largely neglected Linnaeus, 1758 species from continental Spain, Dufour, 1820 and L. Koch in Rosenhauer, 1856, are examined in this paper. After efforts in locating both species' type series in eight European institutions, the specimens are considered to be lost. Consequently, the identifications of both taxa were approximated by collating their descriptions with the morphology of all other sympatric Scolopendromorpha. Then, compatible topotypes for both species were collected, and among these a neotype for each taxon were selected and compared with the type series of their respective closest relatives. Finally, both and are proposed to be conspecific with Lucas, 1846. Therefore, the name is here established as (senior) and of , is declared as , and (junior) is reallocated to . Moreover, the specimens making up the type series of are also indicated and redescribed, the genitalia are illustrated for the first time, and its specific epithet is briefly reviewed, remaining unaltered in respect of its original spelling.
