Pachymerinus

Pachymerinus is a genus of centipedes in the family Geophilidae. It was described by Italian entomologist Filippo Silvestri in 1905.^[2] Centipedes in this genus feature elongate heads, elongate forcipules with denticles, scattered coxal pores, and few sternal pores, if any; the intermediate part of the labrum is narrow and has no denticles. These centipedes range from about 3 cm to 8 cm in length, have 47 to 81 pairs of legs, and are found in Chile and southeast Australia.^[3] The Australian species Pachymerinus froggatti is notable for its relatively small size, measuring only 28 mm in length.^[4] The larger Chilean species P. porteri measures 46 mm in length but can have as few as 47 leg pairs (47 to 49 in males, 47 to 51 in females),^[5][6] the minimum number recorded in this genus. The Chilean species P. pluripes measures only 32 mm in length but can have 79 or 81 leg pairs,^[5][6] the maximum number recorded in this genus. The Chilean species P. canaliculatus is known from a female specimen with 75 leg pairs and is notable for its large size, measuring 75 mm in length.^[5][6]
