Among these, a recent field survey uncovered several striking specimens featuring alternately long and short legs on each diplosegment, a morphological trait previously unseen in the family Paradoxosomatidae or any other diplopods, except for the genus Pandirodesmus Silvestri, 1932 (family Chelodesmidae). Using mitochondrial (COI , 16S ) and nuclear (28S ) genetic data, alongside detailed morphological analysis in order to confirm their status, we reconstructed phylogenetic trees of dragon millipedes through maximum likelihood and Bayesian inference. The phylogenetic trees strongly support the monophyly of all dragon millipedes, as well as of each nominal dragon millipede genus. The results also revealed the new specimens forming a distinctly separate clade that is closely related to Spinaxytes . Based on these findings, we establish a new monotypic genus of dragon millipedes to accommodate a new species, Alternaxytes bipectinata gen. nov., sp. nov., within the tribe Orthomorphini of the family Paradoxosomatidae. Morphologically, Alternaxytes gen. nov. is characterised by unique gonopodal features and heteropodous legs, suggesting a case example of convergent evolution within Diplopoda.

Among its members, the Neotropical laeta group is particularly notable, as it includes the largest spiders of the genus, such as Loxosceles laeta (Nicolet). In this paper, I describe a new species belonging to this group, Loxosceles galianoa , sp. nov., from male and female specimens collected in the dry Argentinean north-west. The new species is the southernmost native member of the laeta group, and its phylogenetic placement is confirmed by a novel phylogenetic analysis based on molecular data and a taxon sampling including members of all Loxosceles species groups. The morphology of the endogyne of the new species prompted me to survey and characterise the morphological diversity of the female genitalia in Loxosceles . I review the homologies of the parts of the female genitalia in this genus. I argue that an enlarged uterus externus with a narrowed opening is synapomorphic for the laeta species group, whereas in the lineage containing the rufescens and gaucho groups the uterus externus may be sclerotised and bear numerous deep transversal ridges. I here hypothesise that Loxosceles is an example of a clade where female genital morphology is more diverse and has accumulated more morphological novelties than that of males. The geographic origin of the medically significant Loxosceles laeta is briefly discussed. Although this species is commonly referred as the 'Chilean recluse spider', I here argue that this species most likely originated in Peru and has been introduced to other South American countries by human action. The type material of Loxosceles accepta Chamberlin, 1920 is examined and illustrated. Loxosceles gaucho Gertsch, 1967 is newly recorded from Argentina and Paraguay.

A recent taxonomic revision of the East Asian endemic subtribe Cristariina within Unionidae has revealed its division into seven genera. As an important part of East Asia, China harbours an exceptionally diverse and highly unique fauna of freshwater mussels. However, a comprehensive understanding of species diversity and phylogenetic relationships of Cristariina remains elusive due to inadequate sampling in previous studies, particularly in China. Here, we conducted comprehensive taxonomic and mitogenomic phylogenetic analyses of Cristariina based on extensive sampling across 17 provinces in China. The COI sequences of Cristariina in GenBank were thoroughly examined, and combined with the sequences obtained from this study, a total of 33 monophyletic groups were identified. By integrating molecular data and morphological characteristics, we describe a new genus and species: Acudonta baitiaoensis gen. nov., sp. nov. , as well as a newly recorded species for China (Cristaria truncata ). Additionally, we confirm that the nominal species Anemina euscaphys syn. nov. , Anemina fluminea syn. nov. and Anemina globosula syn. nov. are junior synonyms of Anemina arcaeformis through integrative taxonomy. Mitogenomic phylogeny establishes the following robust phylogenetic framework at the generic level within Cristariina: ((((Sinanodonta + Acudonta gen. nov. ) + (Beringiana + Pletholophus )) + ((Anemina + Buldowskia ) + Amuranodonta )) + Cristaria ). Besides Sinanodonta and Cristaria , the distribution of other genera of Cristariina in China exhibits distinct faunal regions of endemism.

They are found in two main types of habitats, i.e. puna, pampas and subantarctic grasslands, and Valdivian forests and Chilean matorral, from sea level to nearly 5000m above sea level. We propose a phylogenetic hypothesis of the infratribe based on molecular data obtained by target enrichment (TE) of 621 nuclear loci, totalling 248,373 base pairs, from 53 species of this infratribe and 12 outgroups. Our analysis confirms that Neosatyriti is monophyletic with full support. Based on these results, we propose eight new combinations and two status reinstatements. Molecular data are congruent with morphological characters except for Homoeonympha which appears to be paraphyletic, thus almost all the genera described originally by L. Herrera, K. Hayward and W. Heimlich in the Twentieth century based only on morphological characters are confirmed as valid, except for Haywardella that is synonymised with Pampasatyrus . Neosatyriti diverged from other Pronophilina some 23Ma and split into two major lineages some 20Ma. Our reconstructions do not indicate a single area of origin, rather a multisource origin, but they suggest the Neosatyriti originated in the lowlands, and that their ancestral plants were non-bambusoid grasses. Major divergence of the infratribe started some 12-11Ma when it split into the 'Neomaenas clade' (9 genera), the 'Pampasatyrus clade' (4 genera) and the 'Neosatyrus clade' (5 genera). The next main radiation took place some 7-5Ma with the switch to bamboo host plants and the colonisation of Valdivian forests. The final dispersal of the tribe was associated with the colonisation of Mata Atlantica some 6-5Ma, and high Andean puna in Peru in the Early Pleistocene.

Morphologically, this new species resembles D. vancouverensis and D. gelatinosus in shell size, shape, auricle size and sculpture. However, D. thermus sp. nov. can be distinguished from its congeneric species (including 9 extant and 12 fossil species) by its unequal auricles (the anterior one being larger than the posterior), inwardly recurved anterior auricle of the left valve and a large byssal notch angle of ~90°. Comparisons of genetic sequences from three mitochondrial and three nuclear gene fragments supported the placement of the new species in the genus Delectopecten . Further phylogenetic analyses using these gene markers support that Delectopecten is monophyletic and positioned as an early diverging clade of the family Pectinidae. Additionally, the mitogenome of D. thermus sp. nov. was assembled and annotated, a first for its genus - revealing significant divergences in gene order compared to other pectinids. The 16S rRNA amplicon analysis of the gill tissue indicated that this vent-dwelling scallop does not exhibit symbiosis with chemosynthetic bacteria. A key to all known species of Delectopecten is provided to aid the identification of species in this understudied genus.

In this study, we performed a morphological and molecular analysis (mtCOI-5P , 16S rRNA and 28SD2 rRNA ) of Perinereis specimens from intertidal marine and brackish European localities, mostly focusing on the Mediterranean Sea and the Canary Islands. Two major phylogenetic clades with at least 18 divergent (COI , 19.8; 6.4-28.5%) and completely sorted lineages were uncovered based on original data, 13 of which occurred exclusively in the Mediterranean Sea, a further 5 of which are unique to Italian brackish waters. An additional morphologically similar lineage, corresponding to P. oliveirae , coexisting with the single NE Atlantic lineage of the complex, was also retrieved as an ingroup. Careful morphological inspection, combined with the deep divergence between the two major molecular clades and the perfect match of each clade to the specific paragnath and chaetal types, highlighted the existence of two distinct groups of European Perinereis species: Clade A, which shows features matching historical descriptions of P. cultrifera , and Clade B corresponding to an overlooked morphotype described as P. rullieri . Although paragnaths show a similar pattern in the two clades, their sizes are considerably smaller in P. rullieri and the chaetae are characterised by coarse serration at the base of the spiniger blades and long falciger blades, as opposed to the lightly serrated blades and short falcigers in P. cultrifera . Further overlooked morphological features mainly based on thickness, direction and length of paragnaths, as well as the expansion of posteriormost dorsal ligules were also revealed within each major clade, which together with geographic and environmental boundaries allowed for the differentiation of most of these lineages without molecular data. Thirteen new species are here formally described, eight belonging to Clade A: P. caesarea sp. nov., P. faulwetterae sp. nov., P. houbinae sp. nov., P. maleniae sp. nov., P. miquellai sp. nov., P. muscoi sp. nov., P. nieri sp. nov. and P. twobae sp. nov.; and five belonging to Clade B: P. castellii sp. nov., P. juno sp. nov., P. jupiter sp. nov., P. minerva sp. nov. and P. tibicena sp. nov.

Several morphologically based taxonomic studies have been undertaken on some of these genera recently, but their classification, diversity and species delineations have not been evaluated using an integrative taxonomic approach. In the present study, we combine morphological characters and mitochondrial DNA data to assess the taxonomic status of taxa in this group. Different methods of molecular species delimitation, especially distance-based ones, generally provide strong support for taxon concepts derived from morphological characteristics, demonstrating that these are well able to delineate natural species and assess taxonomic diversity in this group of weevils. Exceptions are that molecular analyses indicate Siraton internatus (Pascoe) to be more closely related to Demyrsus than to S. roei (Boheman), rendering Siraton a paraphyletic taxon, and a genetically distinct but morphologically cryptic species of Miltotranes to occur south of Cairns. A key to all genera and species of the Tranes group is presented.
