Abstract
|
A recent phylogenetic study based on DNA sequence data (COI + 18S rDNA) together with basic morphological characteristics demonstrated the presence of four novel lineages within the widely distributed South African velvet worm species Peripatopsis moseleyi sensu lato (Onychophora, Peripatopsidae). In the present study the morphological variation within P. moseleyi (Wood-Mason, 1879) is quantified and the novel species delineated and described. A total of 31 new specimens were collected from the Amathole Mountains in the Eastern Cape while a further 12 specimens were collected from Mount Currie Nature Reserve, KwaZulu-Natal, South Africa. These samples together with selected specimens from the DNA study material were subjected to scanning electron microscopy (SEM) to investigate the presence of diagnostic morphological characters that could potentially be utilized in the delineation of the four novel lineages. The species diagnosis of P. moseleyi (Wood-Mason, 1879) is elucidated and amended since the original type description is inadequate and could apply to several Peripatopsis taxa. A neotype for P. moseleyi is designated because the syntypes appear lost. Four new species of Peripatopsis Pocock, 1894 are described; viz. Peripatopsis birgeri sp. nov., P. hamerae sp. nov., P. janni sp. nov., and P. storchi sp. nov.
