Mecistocephalus is a genus of centipedes in the family Mecistocephalidae. It was described by British entomologist George Newport in 1843.[1][2]
Description

Centipedes in this genus range from 2 cm to 10 cm in length and usually have 45 to 51 pairs of legs, but some have more, up to as many as 101 leg pairs.[3] Most species in this genus have 49 pairs of legs (e.g., Mecistocephalus punctifrons and M. pallidus),[4] but other species have 51 pairs (e.g., M. sechellarum and M. lifuensis), 47 pairs (e.g., M. angusticeps and M. tahitiensis), or 45 pairs (e.g., M. nannocornis and M. spissus).[5][6]

Intraspecific variation in the number of leg-bearing segments within each sex has been recorded among the species with the greatest number of legs in this genus: M. diversisternus, which has 57 or 59 leg pairs, M. japonicus, which has 63 or 65 leg pairs, and M. microporus, which has odd numbers of leg pairs ranging from 93 to 101, the maximum number in the family Mecistocephalidae.[7][3]
Distribution

Centipedes in this genus occur mainly in tropical and subtropical regions of south and east Asia, with some also found in temperate areas and in the Americas.[3]
