“…A mitogenomic analysis recently challenged the placement of the order Coronatae, such as Periphylla , within Scyphozoa ( Kayal et al, 2013 ; but see Kayal et al, 2017 ) and the new family Drymonematidae was created based on morphological, molecular, and life history data ( Bayha & Dawson, 2010 ; Bayha et al, 2010 ). Studies employing molecular and/or morphological data have revealed novel species in multiple scyphozoan genera, including the moon jellyfish Aurelia ( Dawson & Jacobs, 2001 ; Schroth et al, 2002 ; Dawson, 2003 ), the genus Drymonema ( Bayha & Dawson, 2010 ), the upside down jellyfish Cassiopea ( Holland et al, 2004 ), and the lion’s mane jellyfish Cyanea ( Dawson, 2005 ; Kolbasova et al, 2015 ). Many of these studies have uncovered unrecognized jellyfish invasions and clarified evolutionary relationships in the group (from order to species level) vital to understanding their ecological and economic impacts, and elucidating the evolution of traits that permit these impacts.…”

BackgroundSpecies of the scyphozoan family Pelagiidae (e.g., Pelagia noctiluca, Chrysaora quinquecirrha) are well-known for impacting fisheries, aquaculture, and tourism, especially for the painful sting they can inflict on swimmers. However, historical taxonomic uncertainty at the genus (e.g., new genus Mawia) and species levels hinders progress in studying their biology and evolutionary adaptations that make them nuisance species, as well as ability to understand and/or mitigate their ecological and economic impacts.MethodsWe collected nuclear (28S rDNA) and mitochondrial (cytochrome c oxidase I and 16S rDNA) sequence data from individuals of all four pelagiid genera, including 11 of 13 currently recognized species of Chrysaora. To examine species boundaries in the U.S. Atlantic sea nettle Chrysaora quinquecirrha, specimens were included from its entire range along the U.S. Atlantic and Gulf of Mexico coasts, with representatives also examined morphologically (macromorphology and cnidome).ResultsPhylogenetic analyses show that the genus Chrysaora is paraphyletic with respect to other pelagiid genera. In combined analyses, Mawia, sampled from the coast of Senegal, is most closely related to Sanderia malayensis, and Pelagia forms a close relationship to a clade of Pacific Chrysaora species (Chrysaora achlyos, Chrysaora colorata, Chrysaora fuscescens, and Chrysaora melanaster). Chrysaora quinquecirrha is polyphyletic, with one clade from the U.S. coastal Atlantic and another in U.S. Atlantic estuaries and Gulf of Mexico. These genetic differences are reflected in morphology, e.g., tentacle and lappet number, oral arm length, and nematocyst dimensions. Caribbean sea nettles (Jamaica and Panama) are genetically similar to the U.S. Atlantic estuaries and Gulf of Mexico clade of Chrysaora quinquecirrha.DiscussionOur phylogenetic hypothesis for Pelagiidae contradicts current generic definitions, revealing major disagreements between DNA-based and morphology-based phylogenies. A paraphyletic Chrysaora raises systematic questions at the genus level for Pelagiidae; accepting the validity of the recently erected genus Mawia, as well as past genera, will require the creation of additional pelagiid genera. Historical review of the species-delineating genetic and morphological differences indicates that Chrysaora quinquecirrha Desor 1848 applies to the U.S. Coastal Atlantic Chrysaora species (U.S. Atlantic sea nettle), while the name C. chesapeakei Papenfuss 1936 applies to the U.S. Atlantic estuarine and Gulf of Mexico Chrysaora species (Atlantic bay nettle). We provide a detailed redescription, with designation of a neotype for Chrysaora chesapeakei, and clarify the description of Chrysaora quinquecirrha. Since Caribbean Chrysaora are genetically similar to Chrysaora chesapeakei, we provisionally term them Chrysaora c.f. chesapeakei. The presence of Mawia benovici off the coast of Western Africa provides a potential source region for jellyfish introduced into the Adriatic Sea in 2013.

“…Other possibilities exist: authors may be bringing different expertise, sharing logistical or other costs generated by taxonomic research, and other plausible explanations. However, when 27 authors describe only seven species in seven years (Bayha & Dawson, 2010; Galil et al ., 2010; Nishikawa et al ., 2014; Piraino et al ., 2014; Kolbasova et al ., 2015; Scorrano et al ., 2016; Bayha et al ., 2017), aspects of the International Code of Zoological Nomenclature are being neglected – notably Recommendation 50A – which gains significance in light of bibliometric analyses. If ‘only … some of the authors … are directly responsible for the [species description, those] author(s) … should be identified explicitly’ while ‘co-authors of the whole work who have not had such direct responsibility for the name should not automatically be included as authors of the name’ (ICZN, 1999).…”

Describing species has been a formal, intellectually rich and influential applied and basic area of study for many of the past 260 years. While formally described eukaryotic diversity still falls short of estimated eukaryotic species diversity by many hundreds of thousands of species, some recent accounts have suggested a growing number of taxonomists are within reach of describing all extant species. We present a case study that illustrates, to the contrary, a recent ‘taxonomic impediment’ in part attributable to derogation of taxonomy as a scientific discipline: contemporary practice has re-interpreted taxonomy largely as an endeavour in enumerating species. We argue that challenges lie in (1) a poor understanding of taxonomy's epistemology; (2) excessive displacement of interest toward ecological or molecular studies; (3) over-interpretation of the contributions of multiple authors describing a species; and (4) perspectives that are strongly influenced by well-known taxa. The historical and recent literature on scyphozoans reveal ghosts of taxonomy's past that persist in the present, but suggest also that a renaissance enabled by integrative taxonomy is possible in the (near) future.

ANIMALSThe purpose of a biobank is to accumulate collections that adequately reflect the multidimensional structure of biodiversity (BD), making it possible to explore its various manifestations. An analysis of the scientific status of zoological collections was carried out [1], and it was shown that the collections perform the function of a research sample in BD studies. Their main characteristics are their representativeness, which is further detailed by their informational value, reliability, systemic character, scope, structure, etc.The studies in the "Animals" section are aimed at analyzing key aspects of BD on the basis of an integrated approach combining phylogenomic and phylo-ABSTRACT The "Noah's Ark" project, afoot at M.V. Lomonosov Moscow State University since 2015 and aimed at studying biodiversity, is the largest ongoing Russian project in life sciences. During its implementation, several hundred new species have been described; a comprehensive genetic and biochemical characterization of these species, as well as that of the pre-existing specimens in Moscow University's collections, has been performed. A consolidated IT system intended to house the knowledge generated by the project has been developed. Here, we summarize the investigations around the Moscow University classical biocollections which have taken place within the framework of the project and discuss future promise and the outlook for these collections.
