Geophilus richardi

provided by wikipedia EN

Geophilus richardi is a species of soil centipede in the family Geophilidae found in France, Italy,[1] and the Ionian Islands. Females of this species have 33 pairs of legs; males have 29 or 31.[2] This species is one of only two in the family Geophilidae to include centipedes with as few as 29 leg pairs.[2][3] This species grows up to 10 millimeters long, has no carpophagus pit or pore-fields, and has a gradually tapering, curved pretarsus of the second maxillae.[4] G. richardi lacks typical ventral pores between 2–4mm. The sternites instead bear a small number of pores between 0.5–1mm that differ from micropores, which are unbounded by a cuticular ring. These are possibly the remnants of typical ventral pores, their smaller size being a byproduct of overall miniaturization.[5]
