During the past decade, the ca 120 species of small, colourful tropical Asian freshwater fishes previously referred to the cyprinid genus Puntius have been shown to consist of multiple morphologically distinct evolutionary lineages that resolve as monophyletic groups in molecular studies. Many of these clades have been allocated to new genera such as Dawkinsia, Desmopuntius, Haludaria, Oliotius, Pethia, Puntigrus, Sahyadria, Striuntius and Waikhomia. Others have been assigned to existing but previously poorly delineated genera such as Barbodes and Systomus, while some 40 species remain in Puntius. The divergent morphology of several species retained in Puntius suggests, however, that the systematics of this group requires further attention. Here, based on a phylogeny incorporating newly generated data from the mitochondrial cytochrome b (cytb), mitochondrial cytochrome c oxidase subunit 1 (cox1), nuclear recombination activating protein 1 (rag1), and interphotoreceptor retinoid‐binding protein (irbp) gene markers, we investigate the interrelationships of the species of Puntius in Sri Lanka in the wider context of their Indian and Southeast Asian congeners. We identify three well‐supported monophyletic groups that warrant recognition as new genera: Rohanella (type species Puntius titteya), Plesiopuntius (type species Gnathopogon bimaculatus) and Bhava (type species Puntius vittatus). The first of these is endemic to rainforest streams in Sri Lanka's perhumid southwestern wet zone, whereas the latter two are widely distributed in both Sri Lanka and southern India, including the Western Ghats. Our study highlights the presence of distinct evolutionary lineages among several widespread species.

The genus Saguinus comprises three principal clades that diverged in the Middle to Late Miocene. Their taxa are ecologically differentiated and allopatrically distributed. These clades were recently recognized as different genera, Saguinus, Tamarinus and Oedipomidas. In Tamarinus, the phylogenetic relationships among species/subspecies are poorly understood. Thus, in this study we present a comprehensive dated genomic phylogeny based on double digest restriction associated DNA for all known species and subspecies of Tamarinus. We also tested whether that Tamarinus imperator and Tamarinus subgrisescens are different species, as morphology‐based taxonomy, phenotypical divergences and mitochondrial genes recognized them as two different species. Additionally, we reconstructed time‐calibrated phylogenetics tree hypotheses of all extant species and subspecies of the genera Saguinus, Tamarinus and Oedipomidas. Our analysis robustly supported the phylogenetic hypothesis of all species/subspecies of the genus Tamarinus; strongly supported a divergence between the three clades, Saguinus, Oedipomidas and Tamarinus; and provided support for T. imperator and T. subgrisescens as distinct species. Therefore, we reiterate and ratify the division of Saguinus into three genera, supporting the taxonomic proposal for these genera.

Patterns of larval food plant use and immature stage morphology help clarify Neotropical butterfly species diversity, and, in many cases, lineages identified with molecular data are corroborated by morphology and ecology of immature stages. Here, we investigate cryptic species in Adelpha butterflies (Nymphalidae), a group known for challenging adult wing similarity coupled with mimicry, and for its remarkably wide larval food plant breadth. We focus on the Adelpha serpa‐group and in particular Adelpha serpa celerio, whose immatures have been documented feeding on 11 plant families. Our analyses of A. serpa, and among serpa‐group species across the Neotropics, revealed evidence of cryptic species, but the pattern within A. serpa celerio showed relatively weak mtDNA and morphological differences, and no differentiation in food plant use. We conclude that A. serpa should be revised and recognize A. serpa to include the nominate subspecies and recognize A. celerio (revised status) as a geographically widespread species and a larval food plant generalist that contains A. c. celerio (revised status), A. c. duiliae (revised status) and A. c. diadochus (revised status). Four additional species within the serpa‐group show strong evidence of harbouring allopatric cryptic species, and further research should be done to clarify their species limits.

Cryptic diversity is frequent among lizards from the Neotropical region. In particular, geckos belonging to the genus Homonota exhibit high levels of phenotypic and ecological conservatism. Homonota uruguayensis is endemic to rocky outcrops in the Uruguayan Savanna, and a previous study based on mitochondrial DNA (mtDNA) revealed a highly divergent clade in an isolated population. In this study, we used a set of two mitochondrial (Cytb and 12S) and six autosomal (DMLX, MXRA, PRLR, SNCAIP, H19B and H30B) genetic markers to evaluate the taxonomic status of different populations of H. uruguayensis. We then used morphological data to further check the favoured coalescent model of species delimitation. A careful re‐evaluation of meristic and continuous morphological traits within the H. uruguayensis complex indicated that the new species can be morphologically distinguished. The species tree confirmed the deep divergence times associated with the new species previously reported for mtDNA and indicated congruence among independent gene trees. Overall, the results clearly support the recognition of a new species, based on deep genetic divergence and morphological differentiation. While the full geographic range of the new species has not been thoroughly characterized, the localized endemism in a patch of rocky outcrops surrounded by intense silviculture activity strongly suggest that the new species should be considered to be under some degree of threat.

Single‐locus molecular delimitation plays a key role in meeting the need to expedite the exploration and description of the species on our planet. Multiple methods have been developed to aid data interpretation over the past 20 years, but species delimitation remains difficult due to their varying performance. In this study, we examine the accuracy of five widely used delimitation methods (i.e. BIN, ABGD, ASAP, GMYC and mPTP) in analysing 63 empirical data sets that included 1850 mitochondrial COI sequences derived from eriophyoid mites assigned to 456 morphospecies. Our results establish that all five methods resolve approximately 90% of morphospecies. We investigated some factors which might affect the species delimitation results, that is taxonomic rank, number of haplotypes per species, mean number of host plants per species, and geographical distance among sampling sites. We found complex interactions between these factors which affected delimitation effectiveness. An increase in haplotype number negatively affected delimitation accuracy, while increased geographical distance improved delimitation accuracy. BIN was influenced by the number of host plants per species as cryptic speciation linked to host plant usage might be prevalent in eriophyoid mites, while ABGD was not significantly impacted by other factors. Our results highlight multiple factors that affect molecular species delimitation and underline the value of employing multiple analytical approaches to aid species delimitation.

The aim of the study was to clarify the phylogenetic relationships among Northern European Ancistrocerus and comparison of the applicability of evolutionarily neutral and non‐neutral markers for reconstruction of phylogeny. We used a 19,400 bp long dataset that included parts of mitochondrial DNA, nuclear rDNA operon, and 10 nuclear protein‐coding genes. Application of molecular barcoding and species delimitation algorithms unveiled a presence of cryptic species, A. balticus sp. n., in the trap‐nesting wasp communities of the centre of Europe. We assessed the morphological, biological, and ecological differences of it from the sibling A. trifasciatus and updated the regional identification key. Phylogeny reconstruction using the neutral and the presumably non‐neutral markers resulted in different tree topologies. Evolutionary congruence of the rDNA operon with the other markers was relatively low. Evolutionary rate of the mitochondrial genes was 7–8 times as high as that of the exons of the nuclear genes, therefore, the mitochondrial markers overshadowed the nuclear ones in the phylogeny reconstructions. We assumed that at the speciation level, we might consider two different patterns of phylogeny: one based on evolutionary time and neutral changes, and the other based on adaptive evolutionary pathways under directional selection pressures. We assessed the effect of directional selection on the nuclear protein‐coding genes, applying the Spearman's rank correlation between pairwise phylogenetic distances among species, estimated using exons, and these distances, estimated using introns. One of these markers demonstrated a lack of positive correlation, implying a variable directional selection pressure on the coded protein.

With 175 described genera and 1556 described species, Family Cercopidae is currently divided into two subfamilies: the paraphyletic Cercopinae and the monophyletic Ischnorhininae. This study, with emphasis on the family Cercopidae, is in line with the extensive work of Cryan and Svenson which is the first phylogenetic study testing the monophyly of this family and higher‐level relationships within Cercopoidea. This study includes more representative taxa from Old World regions. The results of the phylogenetic analysis based on DNA nucleotide sequence data (18S rDNA, 28S rDNA, histone 3, and cytochrome oxidase I) show that Cercopidae is not monophyletic. Three major lineages are recovered: (1) the lineage Microsargane Fowler, 1897 + Hemitriecphora Lallemand, 1949 which is the sister group to Aphrophoridae + Epipygidae, (2) most of the Old World Cercopidae appear as a monophyletic lineage that can be subdivided into two clades, and (3) the monophyletic New World Ischnorhininae, which is separated from the rest of Cercopidae and basal to the two other lineages. It is proposed that Microsargane and Hemitriecphora should be removed from Cercopidae and placed within Aphrophoridae, and only the monophyletic Old World lineage should be kept as Cercopidae sensu stricto. The two subfamilies Cercopinae and Cosmoscartinae, corresponding respectively to the monophyletic lineage groups 2 and 3, should be kept with minimal changes on the tribal level, and the subfamily Ischnorhininae should be raised to family level Ischnorhinidae stat. nov.

Diestramimini is one of the two tribes of Aemodogryllinae and is mainly distributed in southern China and Southeast Asia. The intergeneric phylogenetic relationship and historical biogeography of this tribe remain unclear. Here, we present the first phylogenetic and biogeographical analyses of Diestramimini based on three mitochondrial (COI, 12S rRNA and 16S rRNA) and two nuclear (18S rRNA and 28S rRNA) gene fragments. The molecular phylogenetic inference strongly supports the monophyly of Diestramimini and recovers the sister‐group relationship between Diestramima + Tamdaotettix and Arboramima + Gigantettix. A new genus, Bidiestramima Zhu & Shi gen. n., is established and recovered as sister to all the remaining genera of Diestramimini. Moreover, a new species Bidiestramima hekouensis Zhu & Shi gen. et sp. n. is described. Mimadiestra is recovered as paraphyletic, and thus, we propose two new combinations based on the combination of morphological and molecular evidence: Bidiestramima dicha comb. n. and Tamdaotettix (Laotettix) gracilus comb. n. Divergence time estimation and reconstruction of ancestral areas indicate that Diestramimini in China may have originated from Southern Yunnan and Guangxi during the mid‐Oligocene and had two separate evolutionary routes. The diversification of Diestramimini has been driven by several dispersal and vicariance events since the Miocene, linked to the uplift of the Himalaya–Tibetan Plateau, the formation of the monsoon and climate fluctuations.

Muricidae is one of the most species‐rich and morphologically diverse families in Gastropoda, with a worldwide distribution. The classification of Muricidae has traditionally been based on shell and radular characteristics; however, the phylogenetic relationships within the family are debated due to morphological convergence and plasticity. In this study, to explore the phylogenetic relationships of Muricidae, we sequenced 11 muricid mitochondrial (mt) genomes and compared them with 13 previously reported complete muricid mt genomes. All muricid mt genomes shared the same gene arrangement and exhibited conserved genome size and nucleotide composition. Three‐nucleotide deletions in atp8 and nad4, and three‐nucleotide insertions in nad2 were detected in Rapaninae. Both maximum likelihood and Bayesian inference analyses supported the monophyly of each subfamily studied (Ocenebrinae, Muricinae, Rapaninae and Ergalataxinae). Ergalataxinae was recovered as the sister taxon of Rapaninae, refuting the traditional morphology‐based placement of Ergalataxinae within Rapaninae. In Rapaninae, Indothais was confirmed to be monophyletic and determined to be a valid genus. Similarly, Drupina was determined to be an independent genus rather than a subgenus of Drupa. Purpura was recovered as a paraphyletic group, with Purpura panama being sister to Reishia + Rapana + Indothais and clustering with Purpura bufo.

The classification of Muricidae has traditionally been based on shell and radular characteristics; however, the phylogenetic relationships within the family are debated due to morphological convergence and plasticity. In this study, to explore the phylogenetic relationships of Muricidae, we sequenced 11 muricid mitochondrial (mt) genomes and compared them with 13 previously reported complete muricid mt genomes. All muricid mt genomes shared the same gene arrangement and exhibited conserved genome size and nucleotide composition.
