Scolopendropsis duplicata

Scolopendropsis duplicata, is a scolopendromorph centipede discovered in central Brazil in 2008 by Museum scientists.

There are over 700 species of scolopendromorph centipedes and until 2008, all known species had either 21 or 23 trunk segments. This feature is so conserved that it is used to classify these centipedes into families.

Scolopendropsis duplicata, is the first known instance of 

  • segmentation numbers of 39 or 43 almost double those of related species
  • a scolopendromorph having variable segment numbers (either 39 or 43) within a population

Species detail

Length
segmentation

  • 39-segmented individuals ranging from 31-74 mm. 
  • 43-segmented individuals from 53-78 mm.
Growth

All scolopendromorph centipedes have epimorphic development, hatching from the egg with the adult trunk segment number.

Lifecycle

Scolopendromorph centipedes all have maternal care, the mother brooding the eggs and early hatchling instars by wrapping her body around them, but embryos or hatchlings have not been collected yet for this species.

Ventral view of the head of Scolopendropsis duplicata, showing the maxillipede coxosternum. Taxonomically important characters for identifying Scolopendropsis include the shape of the tooth plates and the arrangement of sutures on the coxosternum. This specimen is the holotype, deposited in the Museu Nacional, Universidade do Rio de Janeiro.
