Scopalina ruetzleri has a relatively wide morphological variation in habit and spicules' shape and size, which raises suspicions of it being a species complex. The examination of a comprehensive collection of previously identified S. ruetzleri specimens enabled us to reassess intraspecific variation through an integrative approach, which included genetics, phylogenetics, statistical, and morphological data. Additional material of Scopalina erubescens and Scopalina hispida from the Western Atlantic were included in the analyses. From the previous intraspecific variation of S. ruetzleri we discovered a cryptic species, Scopalina brasiliana sp. nov., differing subtly in spiculation, as in the proportion of styles and styloids. Both species are highly supported by phylogenetic analyses with COX1, 16S, ITS2, and 28S rDNA sequences. A second cryptic species from Bermuda was also revealed, but only with available ITS2 data; it remains undescribed. Scopalina ruetzleri and S. brasiliana sp. nov. were found in sympatry across a large sector of the Tropical Southwest Atlantic Province, with the new species being currently the only Scopalina occurring in areas further south, in the Warm Temperate Southwestern Atlantic Province. Scopalina ruetzleri was also sympatric with S. hispida in the Tropical Northwestern Atlantic Province, in which the latter appears to be restricted, while S. ruetzleri seems capable of advancing southwards, through the provinces of the Northern Brazilian Shelf and the Southwest Tropical Atlantic. Thus, the continuous distribution of S. ruetzleri from the Gulf of Mexico and the Caribbean to the Brazilian areas seems unaffected by freshwater and sediments carried by the Amazon River, with records of the species at the mouth of this river, at 55 m depth. The southern region of Patagonia hosts no Scopalina species yet, while the Magellanic Province houses three, S. erubescens and Scopalina bunkeri, both from the Malvinas/Falkland Islands, with the former also described here from the Magellan Strait (South Patagonia), and Scopalina cribrosa from Northwest Patagonia. Given the apparent regionalization and sympatry of Scopalina species, many of which have been described in recent years, we advocate for a widespread revision of all other lineages through integrative approaches whenever possible in order to solve taxonomic conflicts, reveal cryptic species, and highlight biogeographic boundaries of these relict heteroscleromorph sponges.

Despite significant advances in the deep-level phylogenetics of jumping spiders, many shallow-level relationships remain poorly understood, as exemplified by the widespread Southeast Asian genus Lechia Żabka, 1985. The phylogenetic placement of this genus is uncertain, compounded by the lack of a formal male description for its type species, Lechia squamata Żabka, 1985. In this study, we present the first formal description of the male of L. squamata, improving the morphological diagnosis of this genus and leading to the proposal of two new synonyms: Phintelloides manipur Caleb, 2020, syn. nov. and P. scandens Deeleman-Reinhold, Addink & Miller, 2024, syn. nov. To clarify the phylogenetic placement of Lechia, we reconstructed phylogenies using both phylogenomic (ultraconserved elements, UCE) and Sanger datasets. The UCE phylogeny provided well-supported backbone relationships, while the Sanger dataset maximized the taxonomic coverage of Lechia and related genera by integrating COI and 28S sequences extracted in silico from the UCE data with available GenBank sequences. Both phylogenetic and comparative morphological evidence strongly support the placement of Lechia within the tribe Chrysillini, closely related to the genera Phintelloides Kanesharatnam & Benjamin, 2019 and Proszynskia Kanesharatnam & Benjamin, 2019. Furthermore, our analyses validate the placement of Heliophanoides and Nandicius within Chrysillini, corroborating previous morphology-based classifications.

We reassessed the identity of Ostrea subucula and the validity of Booneostrea Harry, 1985 using an integrative approach that combined shell morphology, anatomy and multilocus phylogenetic data. Phylogenetic analyses reveal two deeply divergent, reciprocally monophyletic lineages. The Western Indian Ocean lineage corresponds to O. subucula sensu stricto and ranges from Rodrigues to Yemen and Oman. By contrast, the northern Arabian-Persian Gulf lineage represents a distinct species, here described as Ostrea sorosubucula sp. nov. Despite substantial genetic divergence, morphological differences are subtle, mainly in the adductor muscle scar. Re-examination of historical material reveals that the type concept of Booneostrea is based on misidentified or now-untraceable shells. Ostrea subucula and Ostrea setoensis Habe, 1958 are morphologically and genetically distinct, and O. subucula does not conform to the shell features historically used to define Booneostrea. We conclude that Booneostrea cannot be applied in a taxonomically consistent and meaningful way and should be treated as a nomen dubium. By resolving this long-standing confusion and documenting an endemic Gulf lineage, this study significantly contributes to stabilising generic concepts in Ostreinae and demonstrates the power of integrating molecular and morphological evidence in oyster systematics.

The Myzostomida are an enigmatic clade of marine annelids that live as obligate symbionts on or inside their predominantly echinoderm hosts. Species of myzostomid have diverse morphologies and lifestyles, ranging from cyst and gall forming, to parasitic host eating, and free-living ectocommensalism. Largely described from shallow tropical waters, there is currently limited information on myzostomids from the deep sea. Here we describe, using integrated morphological and molecular data, the first genus and two species of myzostomid from the abyssal seafloor, found living ectocommensally on porcellanasterid starfish from 3490 to 4362 m deep in the central and North Pacific Ocean. Molecular phylogenetic analyses using both nuclear (18S rRNA, H3) and mitochondrial (COI, 16S rRNA) markers recovered Myrmekimyzostomumgen. nov. as monophyletic, and the sole commensal genus in a clade of parasitic species associated with asteroids and ophiuroids. Trait-mapping across the phylogeny suggests the ancestral myzostomid form likely lived ectocommensally on stalked crinoids, with parasitism emerging multiple times in their evolutionary history. These new taxa underline the substantial ecological and evolutionary novelty that can be found in the deep sea.

This is especially evident in environments where sampling is difficult, such as the deep-sea. Specimens belonging to the subfamily Gymnonereidinae were collected from various deep-water habitats in Brazil. Initial morphological analysis divided them into two morphotypes belonging to the genera Micronereides and Ceratocephale. However, species delimitation using the COI genetic marker revealed the presence of seven distinct species, suggesting the existence of cryptic species complexes within each morphotype, where species are morphologically indistinguishable. Three species recovered in the analyses belong to the genus Micronereides and are morphologically indistinguishable from the type species Micronereides capensis, previously reported in Brazilian deep waters. The lack of molecular data on the type M. capensis hampers the description of these new species. We, therefore, suggest the existence of the Micronereides capensis cryptic complex. Similarly, the Ceratocephale cryptica cryptic complex encompasses the remaining four species identified in this study. Among them, only Ceratocephale cryptica sp. nov. is formally described here. This study provides strong support for the validity of the genus Micronereides, which was questioned in previous studies. Cryptic speciation processes are further discussed, comparing evolutionary divergence rates of the different genetic markers used for phylogenetic inference. These results highlight the challenges of deep-sea species delimitation, calling for revised biodiversity assessments and more complete genetic databases, especially including type species sequences, and at the same time reinforcing the critical role of integrative taxonomy in revealing cryptic diversity.

However, when character conflicts arise, such as discrepancies between shell morphology and molecular data, relying solely on prior assumptions about the systematic significance of characters and taxa can lead to erroneous conclusions. This is because inductive reasoning, unlike deduction, produces probabilistic rather than definitive conclusions. The uncertainty inherent in induction stems from the incompleteness of our observations; thus, using a partial or selective dataset increases the likelihood of error. To address this issue, we conducted a case study using the genus Cathaica. First, we reconstructed molecular phylogenies based on all available published datasets. Next, we performed discrete and continuous character optimisations to identify apomorphic characters. Finally, we explored the correlation between molecular distances and shell morphological distances. Our character optimisation revealed that shell characters are highly variable and often discordant with molecular data, whereas discrete genital characters exhibit stronger congruence with phylogenetic relationships. Notably, molecular distances were not significantly correlated with shell landmark Euclidean distances, underscoring the mismatch between genetic and shell-based evidence. Based on these findings, we propose that C. zhangcunxiangi, C. wangjiaxunae and C. sculptilis are synonyms of C. fasciola, and C. mengi is a synonym of C. pyrrhozona.
