This paper presents a description of a new monotypic genus of the family Anthroleucosomatidae – Cornogonopus pavicevici gen. nov., sp. nov. – from a cave in eastern Serbia. This new genus is the tenth of the “Bulgarosoma” complex of genera. The new species is illustrated with micrographs, SEM photographs, drawings, as well as in situ photographs. Further, an identification key to all 10 genera of this complex is provided and the structure of the posterior and anterior gonopods is briefly discussed. The geographical distribution of all genera is presented, with a distribution map attached.

Sibiriulus mikhaljovae sp. nov. is described from the Altai Province, southwestern Siberia, Russia. This new species differs from its congeners mainly by the presence of a longitudinal crest inside the apical fovea of the gonopod mesomere. Brief descriptive remarks concerning several previously described Sibiriulus species allow for the definition of the genus to be supplemented and refined. All eight currently known species of Sibiriulus are keyed.

During the present study, DNA sequence data, gross morphology and scanning electron microscopy (SEM) were used to examine cryptic species boundaries in the velvet worm, Peripatopsis clavigera species complex, from the southern Cape Afrotemperate forest belt in South Africa. Sequence data were generated for the mitochondrial COI and the nuclear 18S rRNA loci and phylogenetically analysed using both a Bayesian inference and a maximum-likelihood approach. Both the COI data and the combined DNA sequence topology (COI+18S) revealed the presence of five clades within the Peripatopsis clavigera species complex, and revealed that specimens from Tulbagh were distantly related and represented a sixth clade. The evolutionary distinction of the five clades was corroborated to varying degrees by the four species-delimitation methods (ABGD, PTP, GMYC and STACEY); however, both the gross morphological data and the SEM provided limited diagnostic differences between the five clades. Furthermore, the COI haplotype network and phylogeographic analyses provided evidence of genetic isolation between lineages that are currently syntopic. The distribution of genealogically exclusive and widespread maternal lineages was atypical among velvet worms and did not reflect the general trend of genetic and geographical isolation. Instead, lineages exhibited admixture among localities, a result most likely due to fluctuations in climatic conditions affecting the southern Cape Afrotemperate forest during the Pliocene–Pleistocene period as evident from our divergence time estimations. Four novel, narrow-range endemic species – P. ferox, sp. nov., P. mellaria, sp. nov., P. edenensis, sp. nov. and P. mira, sp. nov. – are described within the P. clavigera species complex, whereas the Tulbagh specimens are described as P. tulbaghensis, sp. nov. Collectively, these results demonstrate that Peripatopsis likely contains several undescribed species.

The genus Scolopendra Linnaeus, 1758 currently comprises 13 valid species in Mexico. One of the species, Scolopendra aztecorum Verhoeff, 1934 has been considered a potential synonym of S. viridis Say, 1821, S. polymorpha Wood, 1861, or Arthrorhabdus pygmaeus (Pocock, 1895). To shed light on its true status, five of the six syntype specimens were examined, redescribed and illustrated for the first time. Scolopendra aztecorum is diagnosable from all other Mexican species and remains in the genus Scolopendra as a valid species.
