Endogeophilus ichnusae gen. et sp. nov. (Chilopoda: Geophilidae sensu stricto) is described based on three specimens from two localities in south-western Sardinia, examined by light and scanning electron microscopy. The new centipede resembles the rare Ibero-Pyrenean genus Galliophilus Ribaut & Brolemann, 1927 in some features, especially in the forcipular segment, and the temperate European species Geophilus electricus (Linnaeus, 1758) in other features, especially in the ultimate leg-bearing segment. However, the true affinities of E. ichnusae gen. et sp. nov. are uncertain, because the new species departs significantly from the majority of geophilids for the higher number of legs (91–107 pairs in the specimens examined), the slender trunk segments (the sternites being longer than wide), the relatively stout legs (the tarsus being only about twice as long as wide) and the very short setae (≤ 15 mm) scattered on the body surface. All these features are probably derived and suggest adaptation to a more strictly endogeic habit than other geophilids.
