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.

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.
