“…The high genetic distances between the species of Sphaeromimus suggest an early speciation event, as previously suggested by Wesener et al (2010Wesener et al ( , 2014. The COI gene probably lost its resolution due to the accumulation of reverse substitutions over time.…”

“…Until 2005 only known from a single specimen, Sphaeromimus was thought to be based on a mislabeled Indian specimen (Jeekel 1999), but then two new species and many specimens were described from SE Madagascar (Wesener & Sierwald 2005). Morphological (Wesener & VandenSpiegel 2009) and molecular (Wesener et al 2010) studies suggest that Sphaeromimus is more closely related to the Indian genus Arthrosphaera Pocock, 1895 than to the other genera in Madagascar. Seven additional species were described integratively in 2014, including the first gigantic species of the genus, reaching the size of a ping-pong ball .…”

“…Madagascar is host to some of the most spectacular millipedes: different genera of large-bodied pitchblack/bloodred so called "Fire-Millipedes" of the order Spirobolida (Wesener et al 2009a(Wesener et al , 2009b(Wesener et al , 2011, as well as the world's largest giant pill-millipedes, order Sphaerotheriida (see Wesener & Wägele 2008;Wesener 2009), showing island gigantism. All giant pill-millipedes of Madagascar belong to the family Arthrosphaeridae, otherwise only found in India (Wesener & VandenSpiegel 2009;Wesener et al 2010) and are an example of the interesting biogeographical history of the Malagasy fauna. All species of the family are characterized by unique stridulation organs present in both sexes (see also Wesener 2014c), the male harp and the female washboard.…”

Abstract. The species-rich giant pill-millipedes (Sphaerotheriida) often represent a microendemic component of Madagascar's mega-invertebrate fauna. Of the chirping genus Sphaeromimus de Saussure & Zehntner, 1902, ten species have been described. Here, we describe two new species of Sphaeromimus integratively, combining light microscopy, scanning electron microscopy, DNA barcoding and micro-CT technology for the first time in a taxonomic description of a giant pillmillipede. S. kalambatritra sp. nov. and S. midongy sp. nov. are the first giant pill-millipedes collected and described from the mountainous rainforests of Kalambatritra and Midongy. Both species show island gigantism compared to their congeners. Our analysis of the mitochondrial COI gene shows that the two species are related to one another with a moderate genetic distance (9.4%), while they are more closely related to an undetermined specimen from the forest of Vevembe (6.3% and 8.4%). They stand in a basal position with S. ivohibe S. musicus (de Saussure & Zehntner, 1897). The four aforementioned species share a high number of stridulation ribs on the male harp. Our micro-CT analysis provides a look into the head of S. kalambatritra sp. nov. and shows that non-destructive CT methods are a useful tool for studying the inner morphology of giant pill-millipedes.

The subphylum Myriapoda included four extant classes (Chilopoda, Symphyla, Diplopoda, and Pauropoda). Due to the limitation of taxon sampling, the phylogenetic relationships within Myriapoda remained contentious, especially for Diplopoda. Herein, we determined the complete mitochondrial genome of Polydesmus sp. GZCS‐2019 (Myriapoda: Polydesmida) and the mitochondrial genomes are circular molecules of 15,036 bp, with all genes encoded on + strand. The A+T content is 66.1%, making the chain asymmetric, and exhibits negative AT‐skew (−0.236). Several genes rearrangements were detected and we propose a new rearrangement model: “TD (N\R) L + C” based on the genome‐scale duplication + (non‐random/random) loss + recombination. Phylogenetic analyses demonstrated that Chilopoda and Symphyla both were monophyletic group, whereas Pauropoda was embedded in Diplopoda to form the Dignatha. Divergence time showed the first split of Myriapoda occurred between the Chilopoda and other classes (Wenlock period of Silurian). We combine phylogenetic analysis, divergence time, and gene arrangement to yield valuable insights into the evolutionary history and classification relationship of Myriapoda and these results support a monophyletic Progoneata and the relationship (Chilopoda + (Symphyla + (Diplopoda + Pauropoda))) within myriapod. Our results help to better explain the gene rearrangement events of the invertebrate mitogenome and lay the foundation for further phylogenetic study of Myriapoda.
