“…All three conclusions have been partially revealed in previous molecular reconstructions of arthropod or pancrustacean phylogenies 45 , 51 , 52 , but the consequences have never been discussed in detail. It is remarkable that our tree, based on a partial 18S rRNA gene alone (1.7 kb), shows almost the same topology as that of Regier et al .…”

For the first time, the phylogenetic relationships between representatives of all 10 copepod orders have been investigated using 28S and 18S rRNA, Histone H3 protein and COI mtDNA. The monophyly of Copepoda (including Platycopioida Fosshagen, 1985) is demonstrated for the first time using molecular data. Maxillopoda is rejected, as it is a polyphyletic group. The monophyly of the major subgroups of Copepoda, including Progymnoplea Lang, 1948 (=Platycopioida); Neocopepoda Huys and Boxshall, 1991; Gymnoplea Giesbrecht, 1892 (=Calanoida Sars, 1903); and Podoplea Giesbrecht, 1892, are supported in this study. Seven copepod orders are monophyletic, including Platycopioida, Calanoida, Misophrioida Gurney, 1933; Monstrilloida Sars, 1901; Siphonostomatoida Burmeister, 1834; Gelyelloida Huys, 1988; and Mormonilloida Boxshall, 1979. Misophrioida (=Propodoplea Lang, 1948) is the most basal Podoplean order. The order Cyclopoida Burmeister, 1835, is paraphyletic and now encompasses Poecilostomatoida Thorell, 1859, as a sister to the family Schminkepinellidae Martinez Arbizu, 2006. Within Harpacticoida Sars, 1903, both sections, Polyarthra Lang, 1948, and Oligoarthra Lang, 1948, are monophyletic, but not sister groups. The order Canuelloida is proposed while maintaining the order Harpacticoida s. str. (Oligoarthra). Cyclopoida, Harpacticoida and Cyclopinidae are redefined, while Canuelloida ordo. nov., Smirnovipinidae fam. nov. and Cyclopicinidae fam. nov are proposed as new taxa.

“…Pancrustacea (Hexapoda plus Crustacea) hypothesis is supported here, and, for the first time, the position of Tantulocarida is demonstrated to be a sister-group (outside not inside) to Thecostraca (as compared to the discussion of Petrunina et al . 52 ).…”

“…More recently, the enigmatic parasitic Tantulocarida were added within Thecostraca based on analysis of a single ribosomal gene (Petrunina et al, 2014), however, other relationships within Pancrustacea differed significantly from those outlined herein. In light of the paucity of data other than ribosomal genes, we remain ambivalent about including Tantulocarida.…”

Fossil age data and molecular sequences are increasingly combined to establish a timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically disparate animal phylum, have received substantial attention, particularly with regard to questions such as the timing of habitat shifts (e.g., terrestrialisation), genome evolution (e.g., gene family duplication and functional evolution), origins of novel characters and behaviours (e.g., wings and flight, venom, silk), biogeography, rate of diversification (e.g., Cambrian explosion, insect coevolution with angiosperms, evolution of crab body plans), and the evolution of arthropod microbiomes. We present herein a series of rigorously vetted calibration fossils for arthropod evolutionary history, taking into account recently published guidelines for best practice in fossil calibration. These are restricted to Palaeozoic and Mesozoic fossils, no deeper than ordinal taxonomic level, nonetheless resulting in 79 fossil calibrations for 101 clades. This work is especially timely owing to the rapid growth of molecular sequence data and the fact that many included fossils have been described within the last five years. This contribution provides a resource for systematists and other biologists interested in deep-time questions in arthropod evolution.

“…Stygobitic tantulocarids have been described parasitizing harpacticoid copepods in anchialine caves of the Canary Islands (Boxshall & Huys, 1989;). Recent molecular phylogenetic investigations have suggested a close relation between tantulocarids and the subclass Thecostraca, and that Tantulocarida might in fact belong within this subclass as a sister group to Cirripedia (barnacles, Petrunina et al, 2014). However, the precise phylogenetic position of Tantulocarida still awaits further investigation (Petrunina et al, 2014).…”

Abstract:Anchialine caves contain haline bodies of water with underground connections to the ocean and limited exposure to open air. Despite being found on islands and peninsular coastlines around the world, the isolation of anchialine systems has facilitated the evolution of high levels of endemism among their inhabitants. The unique characteristics of anchialine caves and of their predominantly crustacean biodiversity nominate them as particularly interesting study subjects for evolutionary biology. However, there is presently a distinct scarcity of modern molecular methods being employed in the study of anchialine cave ecosystems. The use of current and emerging molecular techniques, e.g., next-generation sequencing (NGS), bestows an exceptional opportunity to answer a variety of long-standing questions pertaining to the realms of speciation, biogeography, population genetics, and evolution, as well as the emergence of extraordinary morphological and physiological adaptations to these unique environments. The integration of NGS methodologies with traditional taxonomic and ecological methods will help elucidate the unique characteristics and evolutionary history of anchialine cave fauna, and thus the significance of their conservation in face of current and future anthropogenic threats. Here we review previous contributions to our understanding of anchialine biodiversity and evolution, and discuss the potential of "speleogenomic" methods for future research in these threatened systems.
