A new species of centipede, Lithobius (Monotarsobius) blascoi n. sp. (Chilopoda, Lithobiomorpha) from Spain

Resum

The new species, from an arid area in the neighbourhood of Pina de Ebro, Zaragoza, is fully described and shows characters typical of centipedes from arid habitats. Despite having 22-23 antennal articles and rarely as many as 25 on one side, reasons are given for referring L. blascoi to Monotarsobius which has about 20 antennal arlicles, rather than to Sigibius in which these articles are more numerous. A similar species from Spain, Lithobius (Monotarsobius) osellai Matic, can be distinguished from L. blascoi by a number of characters.
