Over the years with an interest in the more formal study of myriapods, especially centipedes, I have also accumulated a few items of what we might call "trivia" - prints, pictures etc. The two items here come into that category and I know there are many more like them around and they are offered as light relief for Bulletin readers. I know little about The Penny Magazine but it clearly represents a cheap, presumably weekly, publication dedicated to that great Victorian aim of "self improvement". This issue comprises eight pages with items as varied as "Essays on the lives of Remarkable Painters No.XXXI: Andrea del Sarto", "The English and Irish Ordnance Surveys" and "The Hareem of Ibrahim Pasha". I have abridged the item on Centipedes and Millipedes from the original three pages. "The Rabbit and the Centipede" comes from a children's book of 1907. I am not sure that it sheds any particular new light on myriapod locomotory mechanisms.

This study aimed to classified some species of Chilopoda which is the first record in Iraq. The samples collected from April 2018 to March 2019, in some areas of central of Iraq, which are: Baghdad, Anbar, Babylon, Diyala and Qadisiyah. We found nine species from 183 numbers of samples. The species we recorded for a first time in Iraq are: Scolopendra amazonica, S. afer, Cormocephalus nigrificatus, Cryptops anomalans, Geophilus flavus, Haplophilus souletinus, Lithobius microps, Lamyctes emarginatus and Scutigera coleoptrata. The species were supported by photos, then the samples where stored in Iraq Natural History Research center and Museum.

Abstract: A study on centipedes living on beaches within and around Port-Cros National Park was conducted during the spring of 2019, using hand-collection along transects. One hundred and twenty chilopods (108 of them being Geophilomorpha) were collected, including the halophilous species Henia bicarinata (Dignathodontidae), Geophilus fucorum and Tuoba poseidonis (Geophilidae). The halophilic character of H. bicarinata and G. fucorum was confirmed on the seashore of continental France while T. poseidonis was considered strictly halophilic. Pachymerium ferrugineum (Geophilidae) was considered only halotolerant, in the way it is not restricted to the coastline area. The dominant sediments were observed to have a moderate influence on the presence of halophilous and halobiontic geophilomorphs, with gravel sediments having a more favourable effect. In addition, microhabitats provided by pebbles are of significant importance for halophilic species while the presence of stranded Posidonia seems useful for these species. The availability of driftwood is favourable only when it gives a limited contact with the substrate or the stranded Posidonia layer. Lastly, the impact of human frequentation was very significant regarding halophilic species; all these species were found to be absent where human activity was high. The presence or absence of halophilic centipedes well shows the conservation state of the shore for species living in this habitat. An experimental easy monitoring with identification sheets is given to determine the conservation state of beaches in South-Eastern France.

Résumé: Une étude sur les Chilopodes des plages dans et autour du Parc national de Port-Cros a été réalisée au printemps 2019, à l’aide de récoltes manuelles dans des transects. Cent-vingt chilopodes (108 de ceux-ci étant des Geophilomorpha) ont été collectés, incluant les espèces halophiles Henia bicarinata (Dignathodontidae), Geophilus fucorum et Tuoba poseidonis (Geophilidae). Le caractère halophile d’H. bicarinata et de G. fucorum est confirmé sur le littoral français, tandis que T. poseidonis est considéré comme strictement halophile (= halobie). Pachymerium ferrugineum (Geophilidae) est seulement considéré comme halotolérant, dans le sens où il n’est pas restreint aux milieux salés littoraux en France. Les sédiments dominants ont une influence modérée sur la présence des halophiles et halobiontes, avec les sédiments graveleux ayant un effet plus favorable. En complément, les micro-habitats fournis par les galets sont d’importance significative pour eux ; quant aux posidonies échouées, elles semblent utiles. La disponibilité de bois échoués est considérée comme favorable uniquement quand ils sont en contact étroit avec le substrat ou la couche de posidonies échouées. Enfin, l’impact de la fréquentation humaine est très significatif sur les espèces halophiles : toutes ces espèces sont absentes quand la fréquentation humaine est élevée. La présence ou absence des chilopodes halophiles est un bon indicateur de l’état de conservation des plages pour les espèces d’Arthropodes inféodées à cet habitat. Un suivi expérimental simplifié avec des fiches d’identification est donné pour déterminer l’état de conservation des plages dans le sudest de la France.

Une campagne d’échantillonnage des invertébrés a été menée dans les réseaux souterrains de la ville de Paris et de la banlieue proche. Le présent travail présente les résultats obtenus concernant les myriapodes (chilopodes et diplopodes) issus de ces récoltes. Six espèces de chilopodes (Classe Chilopoda) et neuf espèces de diplopodes (Classe Diplopoda) ont pu être identifiées. Parmi ces dernières, certaines espèces sont nouvelles pour les départements des Yvelines, des Hauts-de-Seine et de la Seine-Saint-Denis. Ces résultats contribuent à l'enrichissement des inventaires et atlas des myriapodes de France (project INAMYFRA).

The P450 family (CYP genes) of arthropods encodes diverse enzymes involved in the metabolism of foreign compounds and in essential endocrine or ecophysiological functions. The P450 sequences (CYPome) from 40 arthropod species were manually curated, including 31 complete CYPomes, and a maximum likelihood phylogeny of nearly 3000 sequences is presented. Arthropod CYPomes are assembled from members of six CYP clans of variable size, the CYP2, CYP3, CYP4 and mitochondrial clans, as well as the CYP20 and CYP16 clans that are not found in Neoptera. CYPome sizes vary from two dozen genes in some parasitic species to over 200 in species as diverse as collembolans or ticks. CYPomes are comprised of few CYP families with many genes and many CYP families with few genes, and this distribution is the result of dynamic birth and death processes. Lineage-specific expansions or blooms are found throughout the phylogeny and often result in genomic clusters that appear to form a reservoir of catalytic diversity maintained as heritable units. Among the many P450s with physiological functions, six CYP families are involved in ecdysteroid metabolism. However, five so-called Halloween genes are not universally represented and do not constitute the unique pathway of ecdysteroid biosynthesis. The diversity of arthropod CYPomes has only partially been uncovered to date and many P450s with physiological functions regulating the synthesis and degradation of endogenous signal molecules (including ecdysteroids) and semiochemicals (including pheromones and defense chemicals) remain to be discovered. Sequence diversity of arthropod P450s is extreme, and P450 sequences lacking the universally conserved Cys ligand to the heme have evolved several times. A better understanding of P450 evolution is needed to discern the relative contributions of stochastic processes and adaptive processes in shaping the size and diversity of CYPomes.

No end to debates on relationships among the four major myriapod subgroups0 aFour myriapod relatives but who are sisters No end to debates on c04/11/2020 a1-150 v203 a

Background: Phylogenetic relationships among the myriapod subgroups Chilopoda, Diplopoda, Symphyla and Pauropoda are still not robustly resolved. The first phylogenomic study covering all subgroups resolved phylogenetic relationships congruently to morphological evidence but is in conflict with most previously published phylogenetic trees based on diverse molecular data. Outgroup choice and long-branch attraction effects were stated as possible explanations for these incongruencies. In this study, we addressed these issues by extending the myriapod and outgroup taxon sampling using transcriptome data.

Results: We generated new transcriptome data of 42 panarthropod species, including all four myriapod subgroups and additional outgroup taxa. Our taxon sampling was complemented by published transcriptome and genome data resulting in a supermatrix covering 59 species. We compiled two data sets, the first with a full coverage of genes per species (292 single-copy protein-coding genes), the second with a less stringent coverage (988 genes). We inferred phylogenetic relationships among myriapods using different data types, tree inference, and quartet computation approaches. Our results unambiguously support monophyletic Mandibulata and Myriapoda. Our analyses clearly showed that there is strong signal for a single unrooted topology, but a sensitivity of the position of the internal root on the choice of outgroups. However, we observe strong evidence for a clade Pauropoda+Symphyla, as well as for a clade Chilopoda+Diplopoda.

Conclusions: Our best quartet topology is incongruent with current morphological phylogenies which were supported in another phylogenomic study. AU tests and quartet mapping reject the quartet topology congruent to trees inferred with morphological characters. Moreover, quartet mapping shows that confounding signal present in the data set is sufficient to explain the weak signal for the quartet topology derived from morphological characters. Although outgroup choice affects results, our study could narrow possible trees to derivatives of a single quartet topology. For highly disputed relationships, we propose to apply a series of tests (AU and quartet mapping), since results of such tests allow to narrow down possible relationships and to rule out confounding signal.

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.

A common terminology for the external morphological characters of centipedes (Chilopoda) is proposed. Terms are selected from the alternatives used in the English literature, preferring those most frequently used or those that have been introduced explicitly. A total of 330 terms are defined and illustrated, and another ca. 500 alternatives are listed.
