Classification Myriapods are classified into four classes: Chilopoda, Pauropoda, Diplopoda, and Symphila. The reproduction process is as follows: the male releases a structure called spermatophore, in which his sperm is contained. In summary, most species of PAU and SYM are small-sized, soil-dwelling and blind, while most of CHI and DIP are eyed.Next
Finally, the matrices were trimmed using MARE v 0.
Twenty-one outgroups were also included: eight chelicerates Liphistius malayanus, Centruroides vittatus, Damon diadema, Archegozetes longisetosus, Araneus diadematus, Egaenus convexus, Euscorpius sicanus, and Nymphon gracile , two onychophorans Peripatopsis capensis and Peripatoides novaezealandiae , and 11 pancrustaceans Daphnia pulex, Folsomia candida, Drosophila melanogaster, Eubranchipus grubii, Triops cancriformis, Nebalia bipes, Anaspides tasmaniae, Hemidiaptomus amblyodon, Tisbe furcata, Vargula hilgendorfii, and Xibalbanus tulumensis.Next

Members of this group include stone centipedes, tropical centipedes, soil centipedes, and house centipedes. The core controversy is the position of Pauropoda; that is, whether it should be grouped with Symphyla or Diplopoda as a sister group.Next
Though symphylans SYM most often are true soil-dwellers, they can live in many different habitats: in leaf litter, in the upper humus layer, and in pure soil, both in upper layers and in the mineral subsoil.
The majority of the components of the rhabdomeric phototransduction pathway are responsible for conferring light sensitivity to photoreceptors from the retinas of cephalopods ; ; , including Gq protein, r-opsins, and transient receptor potential protein.

Introduction Myriapoda is a diverse group of terrestrial arthropods with more than 16,000 extant species including millipedes and centipedes, which are familiar with our daily life.
As for the relationships among the four myriapod classes: Symphyla SYM , Chilopoda CHI , Diplopoda DIP , and Pauropoda PAU , we found a sister group relationship of CHI+DIP, and another sister group relationship of PAU+SYM. The tritobrain collects information from the different appendages that the animal has, either the legs or the mouth appendages.Next
It is particularly worth mentioning that the taxon sampling of the PAU class in this study was represented by two species Pauropus huxleyi and Acopauropus ornatus , instead of just one specie in previous studies which may increase the risk of mispositioning PAU in quartet topology.
Myriapods can have anywhere from fewer than ten to nearly 200 pairs of appendages; they range in size from nearly microscopic to 30 cm in length. However, the interrelationships among the four classes are still controversial.Next
When comparing the results from the two phylogenomic matrices, we found that all testing results of matrix OCC100 were consistent with and covered by that of matrix OCC90.
We compared the LIT genes co-identified between DIP and CHI, and PAU and SYM according to the visual pathways in which the genes participated and. All the analyses recovered Myriapoda as the monophyletic sister group of Pancrustacea with high support. The Chilopoda includes the true centipedes, like the one shown at the top left of this page.
The results showed that almost all hypotheses derived from Dignatha were rejected with high probability.
