Mecistocephalus lifuensis is a species of soil centipede in the Mecistocephalidae family.[1] This species was first described in 1898 by zoologist Reginald Innes Pocock based on type material found on is Lifou Island in New Caledonia, a French overseas territory in Melanesia.[2][3] This centipede is notable for featuring 51 pairs of legs rather than the 49 leg pairs usually observed in the genus Mecistocephalus.[4][5]
Description
[edit]This species has 51 pairs of legs and can reach 41 mm in length.[6] The body is yellow, but the head is a medium reddish shade of brown. Each sternite but the last features a groove down the middle. This groove is Y-shaped on the anterior segments. The last sternite is broad at the base, shaped like a triangle pointed toward the posterior end.[2] The ultimate legs are slender.[6]
Phylogeny
[edit]A phylogenetic analysis of the family Mecistocephalidae based on morphology places M. lifuensis in a clade nested among other species in the genus Mecistocephalus with 49 leg pairs in a phylogenetic tree. This analysis also indicates that the ancestor of this species had 49 leg pairs. Thus, this species evolved from this ancestor through a process that added two leg-bearing segments and two leg pairs.[1]
Distribution
[edit]The species is found in the Loyalty Islands Province of New Caledonia.[1][6]
