Molecular data have been suggesting the existence of a complex cryptic species within taxon Perinereis cultrifera , which has not fully explored yet. In this study, we performed morphological and molecular analysis (mtCOI-5P 16S rRNA 28SD2 ) specimens from intertidal marine brackish European localities, mostly focusing on Mediterranean Sea Canary Islands. Two major phylogenetic clades with at least 18 divergent (COI 19.8; 6.4-28.5%) completely sorted lineages were uncovered based original data, 13 occurred exclusively in Sea, further 5 are unique to Italian waters. An additional morphologically similar lineage, corresponding P. oliveirae coexisting single NE Atlantic lineage complex, was also retrieved as an ingroup. Careful inspection, combined deep divergence between two perfect match each clade specific paragnath chaetal types, highlighted distinct groups species: Clade A, shows features matching historical descriptions B overlooked morphotype described rullieri . Although paragnaths show pattern clades, their sizes considerably smaller chaetae characterised by coarse serration base spiniger blades long falciger blades, opposed lightly serrated short falcigers Further mainly thickness, direction length paragnaths, well expansion posteriormost dorsal ligules revealed clade, together geographic environmental boundaries allowed for differentiation most these without data.

Past molecular studies using mtDNA sequences and alloenzymes signalled the existence of at least two cryptic species within Hediste diversicolor morphotype, in European coasts. However, to this day, no new descriptions have been made. In study, we identified five completely sorted lineages a multi-locus approach, including mitochondrial DNA cytochrome oxidase I gene (COI-5P) nuclear markers ITS2 rRNA 28S rRNA. The data were complemented with morphometric measurements examined through multivariate statistical analysis incorporation dissimilarities. Apart from Baltic Sea, where three occur sympatry, comprises four deeply divergent allopatric rest Europe. They group populations NE Atlantic part Western Mediterranean Sea; Tyrrhenian Adriatic Ionian and, lastly, Caspian, Black northern Aegean Seas. lineage Sea revealed low genetic distances compared one lacked enough specimens for analysis, preventing further conclusions about its independent status.

Two sympatric present showed evidence possible hybridization significant PCA variation them. remaining formally described as species, namely pontii sp. nov.

Finally, neotype is defined H. diversicolor, whose usage restricted lineage. http://www.zoobank.org/urn:lsid:zoobank.org:pub:948C73FC-B07F-40A3-B8FA-03B60DE2089D

Annelid biodiversity studies in the Red Sea are limited and integrative taxonomy is needed to accurately improve reference libraries region. As part of bioblitz effort Saudi Arabia assess invertebrate northern Gulf Aqaba, Perinereis specimens from intertidal marine lagoon-like rocky environments were selected for an independent assessment, given known taxonomic ambiguities this genus. This study used approach, combining molecular with morphological geographic data. Our results demonstrate that found mainly Aqaba not only morphologically different other five similar Group I species reported region, but phylogenetic analysis using available COI sequences GenBank revealed operational units, suggesting undescribed species, P. kaustiana sp. nov. The new genetically close shares a paragnath pattern Indo-Pacific distributed helleri , particular Area III Areas VII–VIII. Therefore, we suggest it may belong same complex. However, differs latter shorter length postero-dorsal tentacular cirri, median parapodia much longer dorsal Tentacular posteriormost wider greatly expanded ligules.

Morphologically similar species are often overlooked but molecular techniques have been effective in signalling potential hidden diversity, boosting the documentation of unique evolutionary lineages and ecological diversity. Platynereis dumerilii massiliensis part a recognised complex, where differences reproductive biology mainly highlighted to date. Analyses DNA sequence data (COI, 16S rDNA D2 region 28S rDNA) populations apparent morphotype P. obtained from broader sampling area along European marine waters, including Azores Webbnesia islands (Madeira Canaries), provided compelling evidence for existence at least 10 divergent lineages. Complementing genetic data, morphological observations better represented revealed two major groups with distinctive paragnath patterns.

Abstract Eumida sanguinea is a recognized polychaete species complex which, in previous studies, has been reported to have additional undescribed diversity. We detected nine lineages by analysing DNA sequence data (mitochondrial: COI, 16S rRNA and nuclear loci: ITS region 28S rRNA) of E. morphotype populations from broader sampling effort European marine waters. Traditional morphological features failed provide consistent differences or unique characters that could be used distinguish these species. However, complementing with morphometrics, geographic range, colour pigmentation patterns, we revealed five new Two derived the previously signalled S21 GB22, which are here named as schanderi sp. nov. fenwicki nov., respectively. Three other based on newly discovered lineages, namely fauchaldi langenecki pleijeli From six remaining, three represented fewer than two well-preserved specimens, prevented further comprehensive analysis. The last were only distinct when using mitochondrial markers. Integrative taxonomy essential elucidate evolutionary phenomena eventually allow informed use complexes exhibiting stasis biomonitoring ecological studies.
