Abstract: Through a combination of morphological and DNA data, a new scolopendrid centipede from southern and southwestern China was revealed: O. tricarinatus sp. nov. The species belong to the politus group but has three sharp tergal keels. Validation of phylogenetic status was performed through molecular analysis of the cytochrome c oxidase subunit I (COI), 16S rRNA, and 28S rRNA sequences from 16 Otostigmus species. Otostigmus tricarinatus sp. nov. was found to be two populations and varied in the number of spines on the ultimate prefemur, the sutures on a sternite, and a pore-free median longitudinal strip in the pore field. The Yunnan-Guizhou plateau population of O. tricarinatus sp. nov. was sister to the clade O. politus politus + O. politus yunnanensis + Guangxi population of O. tricarinatus sp. nov. with strong support from both BI (bayesian inference) and ML (maximum likelihood) analyses (PP = 1, BS = 97%).

The complete mitochondrial genome sequence of Scolopendra mutilans L. Koch, 1878 (Scolopendromorpha, Scolopendridae), with a comparative analysis of other centipede genomes https://zookeys.pensoft.net/article/47820/ ZooKeys 925: 73-88

Abstract: Scolopendra mutilans L. Koch, 1878 is an important Chinese animal with thousands of years of medicinal history. However, the genomic information of this species is limited, which hinders its further application. Here, the complete mitochondrial genome (mitogenome) of S. mutilans was sequenced and assembled by next-generation sequencing. The genome is 15,011 bp in length, consisting of 13 protein-coding genes (PCGs), 14 tRNA genes, and two rRNA genes. Most PCGs start with the ATN initiation codon, and all PCGs have the conventional stop codons TAA and TAG. The S. mutilans mitogenome revealed nine simple sequence repeats (SSRs), and an obviously lower GC content compared with other seven centipede mitogenomes previously sequenced. After analysis of homologous regions between the eight centipede mitogenomes, the S. mutilans mitogenome further showed clear genomic rearrangements. The phylogenetic analysis of eight centipedes using 13 conserved PCG genes was finally performed. The phylogenetic reconstructions showed Scutigeromorpha as a separate group, and Scolopendromorpha in a sister-group relationship with Lithobiomorpha and Geophilomorpha. Collectively, the S. mutilans mitogenome provided new genomic resources, which will improve its medicinal research and applications in the future.

On the taxonomic position of the enigmatic genus Tonkinodentus Schileyko, 1992 (Chilopoda, Scolopendromorpha): the first molecular data https://zookeys.pensoft.net/article/33635/ ZooKeys 840: 133-155

DOI: 10.3897/zookeys.840.33635

Authors: Arkady A. Schileyko, Evgeniya N. Solovyeva

Abstract: The taxonomic position of the monotypic Vietnamese genus Tonkinodentus Schileyko, 1992 (for T. lestes Schileyko, 1992) has been considered in the light of the first obtained molecular data. Both molecular (28S rRNA) and morphological data support the position of this extraordinary eye-less genus within the family Scolopendridae Leach, 1814, a sighted clade, and thus suggests the polyphyly of blind scolopendromorphs. The species diagnosis has been amended and color images of T. lestes provided for the first time.

A taxonomic review of the centipede genus Scolopendra Linnaeus, 1758 (Scolopendromorpha, Scolopendridae) in mainland Southeast Asia, with description of a new species from Laos https://zookeys.pensoft.net/article/7950/ ZooKeys 590: 1-124

DOI: 10.3897/zookeys.590.7950

Authors: Warut Siriwut, Gregory Edgecombe, Chirasak Sutcharit, Piyoros Tongkerd, Somsak Panha

Abstract: The centipede genus Scolopendra in mainland Southeast Asia is reviewed taxonomically based on morphological characters, informed by a molecular phylogenetic analysis using sequences from three mitochondrial and nuclear genes (COI, 16S rRNA and 28S rRNA). Eight nominal species of Scolopendra, namely S. morsitans Linnaeus, 1758, S. subspinipes Leach, 1816, S. dehaani Brandt, 1840, S. multidens Newport, 1844, S. calcarata Porat, 1876, S. japonica Koch, 1878, S. pinguis Pocock, 1891, and S. dawydoffi Kronmüller, 2012, are redescribed together with some revision of type materials. Geographical variation in each species has been compiled with reference to samples that span their distribution ranges in Southeast Asia and some parts of neighbouring areas such as East Asia, the Indian Ocean, and Africa. Comparative study of traditional taxonomic characters from external morphology provides further information to distinguish some closely related species. Scolopendra cataracta Siriwut, Edgecombe & Panha, sp. n., is described from the southern part of Laos, with additional records in Thailand and Vietnam. The phylogenetic framework for Southeast Asian Scolopendra recognizes S. calcarata + S. pinguis, S. morsitans, and a S. subspinipes group that unites the other six species as the main clades. Within the S. subspinipes group, two monophyletic groups can be distinguished by having either slender or short, thick ultimate leg prefemora and different numbers of apical spines on the coxopleuron. Scolopendra arborea Lewis, 1982, is placed in subjective synonymy with S. dehaani. A survey of external morphology of the genital segments confirms its potential for improving species identification in Scolopendra. Some observations on biology and behaviour are recorded based on field surveys in this area.
