Peripatoides

Peripatoides is a genus of velvet worms in the Peripatopsidae family. These animals are nocturnal hunters that spit glue to trap their prey. In New Zealand species of Peripatoides have 14, 15 or 16 pairs of legs.[1] Female Peripatoides produce eggs that are fertilized internally and babies develop inside their mother until large enough to be born, in batches of 4-6, as colourless miniatures of the parents.[1]

Species

The genus contains the following species:[2]

The ovoviviparous (live-bearing) taxon with 15 pairs of legs from New Zealand, Peripatoides novaezealandiae (Hutton 1876), is a species complex of at least five reproductively isolated taxa described in 1998.[3] These new species (Peripatoides aurorbis, Peripatoides kawekaensis, Peripatoides morgani and Peripatoides sympatrica Trewick, 1998) have no morphological characters that distinguish them although they are genetically differentiated.[4][3] Peripatoides novaezealandiae (Hutton, 1876), and the cryptic species are considered nomina dubia by Oliveira et al., 2012 because type locations were identified not holotype specimens. There is debate about whether a species name should be recognized if a whole dead specimen is not held in a museum.[5][6]

In 2014 the New Zealand Department of Conservation also recognized:[7]

  • Peripatoides novaezealandiae (Hutton, 1876)
  • Peripatoides aurorbis Trewick, 1998
  • Peripatoides morgani Trewick, 1998
  • Peripatoides sympatrica Trewick, 1998
