“…Total genomic DNA was extracted using the DNeasy® Blood & Tissue kit (QIAGEN). Partial sequences of the 16S ribosomal ribonucleic acid (16S rRNA) were amplified, purified, Sanger sequenced and finally checked, assembled and edited as in Tanduo et al (2021aTanduo et al ( , 2021b. They were compared with reference sequences from the NCBI nucleotide database both by using BLASTn (Morgulis et al, 2008) and by calculating the genetic P-distances between our samples and the sequences of the two species already deposited.…”

The genus Lysmata Risso, 1816 includes five species in the Mediterranean Sea, namely two well-known species with an Atlantic–Mediterranean distribution, L. seticaudata (Risso, 1816) and L. nilita Dohrn & Holthuis, 1950, and three additional species only known from single records. These are L. kempi Chace, 1997 and L. vittata (Stimpson, 1860), alien species native to the Indo-Pacific region, and L. olavoi Fransen, 1991, a poorly known species originally described from the Azores (Atlantic Ocean) and only reported three decades ago from the eastern parts of the basin. Based on an integrative taxonomic approach, we report the first finding of an ovigerous female of L. olavoi from Italy (Gulf of Naples, Tyrrhenian Sea) and the entire western Mediterranean, thus confirming the presence of this species in the basin and filling a wide gap in its published distribution. It is possible that this taxon was present in the Mediterranean for centuries but went overlooked or undetected due to cryptic habits, occupancy of still unexplored habitats, or misidentification with the highly similar L. seticaudata. Results of phylogenetic analyses confirm the exclusion of L. olavoi by the major lysmatid groups and underline the necessity of multilocus approaches to disentangle its correct phylogenetic position. As the species is still surrounded by a number of unsolved ecological and phylogenetic questions, further field and laboratory work is required to shed light on them.

“…The colonies of Arthropoma cecilii (the only species of this genus known from the Mediterranean) reported from the Tyrrhenian Sea by Chimenz Gusso et al (2014) possibly belong to a different species, as suggested by Min et al (2017). Another example is Bugula neritina consisting of three cryptogenic species only recognizable through molecular analyses (Fehlauer-Ale et al, 2014), two of which presumably occur in the Mediterranean (Tanduo et al, 2021).…”

This paper is an update on the Mediterranean bryozoan diversity since the annotated check-list of Rosso & Di Martino (2016), following the publication of numerous new papers describing new taxa and new species, and adding new records of non-indigenous species. Of the 32 new species described, some replace records of cosmopolitan or widespread species, while some others are the result of the dismantling of species complexes. New records include mainly species and genera previously known from the near Atlantic and subordinately from the Pacific. In addition to replacements, removal of species/genera is also linked to formalized synonymies. These changes also reflect on the composition and representation of families. The updated bryozoan fauna consists of 587 species, 220 genera and 99 families. The different order proportions remain largely unchanged with cheilostomatids (c. 77%) dominating over cyclostomatids (c. 13%) and ctenostomatids (c. 10%). Ten families account for about half of the total species diversity. The new available information is the result of the investigation of habitats and localities previously overlooked, the examination of museum historical collections, as well as a more routinely use of Scanning Electron Microscopy with increasing support from molecular sequencing. Updated biodiversity check-lists represent a unique, simple tool to monitor biodiversity in agreement with the Kunming-Montreal Global Biodiversity Framework adopted by the United Nations.

“…Amplification was performed with an initial denaturation at 95 • C (5 min), followed by 39 cycles of denaturation at 95 • C (1 min), annealing at 47 • C (1 min), extension at 72 • C (1 min), with a final extension at 72 • C (5 min). The PCR products were purified and Sanger sequenced as in Tanduo et al [22]. The chromatograms for each sequence obtained were checked, assembled, edited using BioEdit version 7.0.0, and compared with reference sequences from the NCBI nucleotide (NT) database using the Basic Local Alignment Search Tool (BLAST; www.ncbi.nih.gov/BLAST/, accessed on 1 December 2021) [23].…”

Natural products and their synthetic analogs and derivatives are a traditional source of bioactive molecules with potential development as drug candidates. In this context, Marine Natural Products (MNPs) represent a rich reservoir of diverse molecular skeletons with potential pharmacological activity that, so far, has been mostly explored in cancer and infectious diseases. Starting from the development of a novel bioassay-guided screening platform for immunomodulatory compounds from an in-house MNPs library, we report the identification of the alkaloid lepadin A as a new model compound for immune-based anticancer activity with characteristics that suggest a possible mechanism as Immunogenic Cell Death inducer. The work describes the molecular-based bioprospecting in the Gulf of Naples together with the bioassay-guided fractionation, the chemical characterization of the alkaloid, and the biological activity in mouse dendritic cells (D1).
