Geophilus easoni

Geophilus easoni is a species of soil centipede in the family Geophilidae. [2] [3] It is found throughout Britain and Ireland, [3] and through western France to at least to the foothills of the Pyrenees [4] and to Galicia and northern Portugal. [5] It was distinguished from G. carpophagus only in 2001, and most pre-2001 records from the British Isles probably refer to G. easoni. [3] It's typically shorter than G. carpophagus (up to 40 mm), with fewer leg pairs (between 47 and 51), uniform tan/chestnut coloring, and a greater size and number of coxal pores, as well as a darkly pigmented mid-piece of the labrum which bears blunt teeth. [1] Specimens in north-western Iberia typically have a wider range of leg pairs (between 47 and 55) and are larger (up to 55 mm). [5] It nests on the ground surface under stones and dead wood. [6]
