New World crakes are intriguing, poorly known birds with cursorial cryptic habits; they belong to two unrelated tribes: Laterallini and Pardirallini. Recent genetic studies contributed to the phylogenetic knowledge of these tribes, but a complete phylogenetic reconstruction is still missing. Here, we present the most taxonomically complete dated gene‐based phylogeny of New World crakes, with an emphasis on the Laterallini, including for the first time sequences of Coturnicops notatus, Laterallus levraudi, L. jamaicensis tuerosi and L. xenopterus. We used multilocus (mtDNA + nucDNA) phylogenetic analyses and interpreted our results in light of the natural history of the group. Our novel results show that: (1) L. xenopterus is sister to L. leucopyrrhus; (2) L. j. tuerosi is sister to L. spilonota; (3) C. notatus is sister to the clade that groups the remaining New World black crakes (L. jamaicensis, L. j. tuerosi, L. rogersi, L. spilonota and L. spilopterus); and (4) L. levraudi and L. melanophaius conform a recently diverged clade. Thus, our results indicate polyphyly in this group, particularly for Laterallus and, for the first time, for Coturnicops. We show that some discrepancies with previous studies stem from misidentified samples or sequences of L. leucopyrrhus and Anurolimnas fasciatus. Finally, we provide new preliminary insights into species limits of some taxa, specifically for L. levraudi, L. melanophaius and L. j. tuerosi. Our results set the stage for integrative taxonomic assessments at the generic level in the Laterallini by incorporating phylogenetic (gene‐based) and natural history data.

We reviewed the systematics of Lycodon striatus (Shaw, 1802), including all available name‐bearing types of its synonyms after evaluating phylogeographic (genetics), morphological (morphometry, meristic, and hemipenes), osteological and distribution evidence. Lycodon striatus sensu lato is widely distributed throughout South and Central Asia and mimics elapids. Based on phylogenetic analyses of mitochondrial DNA, we demonstrate that populations from (i) eastern and central Peninsular India plus Sri Lanka and (ii) south‐western parts of Central Asia form two different clades representing two distinct species: L. striatus sensu stricto and L. bicolor comb. nov. respectively. These two clades are sisters to L. deccanensis (in the case of L. striatus) and L. jara (in the case of L. bicolor) and together form two main sister radiations. Although the external morphological variability is high in both species, the genetic variability is higher only in L. striatus but not distinct enough to represent more than one species if using the phylogenetic or biological species concept. The phylogeny of the L. aulicus group hints at Sri Lankan L. striatus, likely having evolved in continental Asia through a probable overland dispersal across the Bay of Bengal (present Palk Strait) into Sri Lanka. This dispersal may have been facilitated by low sea levels during the Pleistocene glaciations when Sri Lanka was connected to mainland India. After considering genetic divergence (with a p‐distance of 1.8%–2.1% in the mitochondrial cytochrome b gene) and morphological evidence, we synonymize the Sri Lankan subspecies, L. s. sinhaleyus Deraniyagala, 1955, with L. striatus sensu stricto. The eastern and central Indian L. striatus (i.e. L. striatus sensu stricto) is morphologically distinct and deeply divergent genetically compared to Tajik and Pakistani L. bicolor with a p‐distance of 13.6% in cytochrome b gene (mtDNA). Interestingly, L. bicolor is conspecific (p‐distance 1.4%) with L. mackinnoni, a western Himalayan endemic, and it reveals intraspecific clinal variation.
在评估了系统地理学（遗传学）、形态学（形态计量学、分生组织学和半萜类）、骨学和分布证据后，我们回顾了条纹石齿龙的系统学（Shaw，1802），包括其同义词的所有可用名称类型。条纹狼牙广泛分布于南亚和中亚，模仿狼牙。基于线粒体DNA的系统发育分析，我们证明来自（i）印度半岛东部和中部加斯里兰卡和（ii）中亚西南部的种群形成了两个不同的分支，代表了两个截然不同的物种：条纹L.striatus senso stricto和双色梳L.bicolor comb。11月。这两个分支是D.deccanensis（在L.stritus的情况下）和L.jara（在L.bicolor的情况中）的姐妹，并共同形成两个主要的姐妹辐射。尽管两个物种的外部形态变异性都很高，但遗传变异性仅在条纹乳杆菌中较高，但如果使用系统发育或生物物种概念，则不足以代表多个物种。L.aulicus群的系统发育提示斯里兰卡L.striatus，可能是通过孟加拉湾（现在的帕尔克海峡）到斯里兰卡的陆上传播在亚洲大陆进化而来的。当斯里兰卡与印度大陆相连时，更新世冰川作用期间的低海平面可能促进了这种扩散。在考虑了遗传差异（线粒体细胞色素b基因的p距离为1.8%-2.1%）和形态学证据后，我们将斯里兰卡亚种L.s.sinhaleyus Deraniyagala，1955与L.striatus senso stricto同义。印度东部和中部的条纹乳杆菌（即狭义条纹乳杆菌）在形态上是不同的，与塔吉克和巴基斯坦的双色乳杆菌相比，在细胞色素b基因（mtDNA）中的p距离为13.6%。有趣的是，双色L.bicolor与喜马拉雅西部特有的L.mackinnoni是同种的（p‐distance 1.4%），它揭示了种内的临床变异。

For too long and with ever‐increasing ferocity during the past decades of an exponentially growing human world population, humankind has been waging a genuine war against nature, of which we ourselves are nevertheless also a part. We are plundering the unique biological treasure, the diversity of species, without which the ecosystems we rely on for our food, our water and so much more would not function. At present, we are already in the midst of a massive decline of populations and species, with a significantly higher extinction rate than the long‐term average. Driven essentially by habitat loss and degradation, direct exploitation through legal and illegal hunting and fishing as well as pesticides and pollution, within decades, 1 million species out of a total of 8 million could go extinct. Alongside climate change, this dramatic decay of biodiversity, that involves also the subsequent loss of ecosystem services, here termed ‘the end of evolution’, is another and by no means lesser threat to humanity. We can still take countermeasures, but we must transform our economy and change our way of living. As most successful strategy the protection of up to 30% of Earth's surface by 2030 was suggested, ideally based on the implementation of a consistent framework of global ecosystems, as it was agreed on by the December 2022 United Nations Conference of Parties (COP15) Montreal meeting for the Conservation on Biological Diversity.

The muscid genera Alluaudinella Giglio‐Tos, 1895, Aethiopomyia Malloch, 1921 and Ochromusca Malloch, 1927 form a monophyletic group supported by immature and adult morphology and a highly specialised snail‐feeding strategy of immature stages. In contrast to the undoubted monophyly of the Alluaudinella‐Aethiopomyia‐Ochromusca clade, previous studies have provided contradictory hypotheses of the subfamiliar position within the Muscidae, and these three genera have been placed in the subfamily Muscinae, Dichaetomyiinae, Phaoniinae and Reinwardtiinae. The systematic position of Alluaudinella, as a representative of Alluaudinella, Aethiopomyia and Ochromusca group, is revised by means of larval morphology, biology and molecular data. Light microscopy (LM), confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM) are used to study the egg and all larval instars of Alluaudinella flavicornis (Macquart, 1855) and a multilocus Sanger sequencing (mS‐seq) approach to examine position within Muscidae. Results are inconsistent with the traditional, morphology‐based concept of the Alluaudinella‐Aethiopomyia‐Ochromusca clade as closely related to Dichaetomyia Malloch, 1921, and the phylogenetic analysis revealed no support for inclusion within subfamily Phaoniinae. Larval morphology in Alluaudinella differs significantly from that of Dichaetomyia (and other Phaoniinae), but resembles that of genera nested in Reinwardtiinae. Based on molecular data and larval morphology a transfer of Alluaudinella, Aethiopomyia and Ochromusca to the subfamily Reinwardtiinae is proposed.

Public databases such as the NCBI's GenBank have been used as repositories for genomic studies for more than 30 years. In this time, our understanding of the natural world, and especially the genomic world, has expanded vastly, and the size of these databases represent this genomic revolution. Databases like GenBank now help populate many molecular studies, supplementing a researcher's newly gathered data with publicly available sequences. Despite this, older sequence records, particularly those from understudied taxa, are frequently not updated in line with this burgeoning understanding, and this means that analyses that leverage this public data – from BLAST through to phylogenetic analyses – cannot do so with the full force of its collective understanding. This is particularly true for environmental DNA (eDNA) records, where older sequence records may identify sequences only to the phylum level, limiting their use in many studies. Here, with a case study of tardigrade 18S sequences, the family identities of 630 sequences, previously only identified to the phylum level, were established using 501 family, genus and species level 18S sequences, effectively doubling the depth and taxonomic resolution of tardigrade 18S sequences in GenBank.

The Iberian Peninsula and south‐western France have been postulated as centres of diversification of a wide variety of endemic earthworm species and genera within the Lumbricidae family. However, the phylogenetic position and identity of some of these endemisms is still uncertain and their phylogeographic patterns totally unknown. In the present study, phylogenetic analyses were carried out with the molecular markers COI, 16S, 28S, ND1 and 12S to clarify the phylogenetic position of the Iberian endemism Iberoscolex in the lumbricid tree. In addition, phylogeographic patterns of three of its species (I. albolineatus, I. carpetanus and I. gerardoi) were studied based on the COI marker and compared with patterns of species showing similar distributions within Castellodrilus (C. ibericus and C. chitae), another Iberian endemism. Phylogenetic trees recovered all species of the genus Iberoscolex (with the exception of I. pseudorroseus) within a clade differentiated from Eiseniona where some authors had placed Iberoscolex species before. Moreover, they were clustered with some species (including the type) of Orodrilus, an Iberian‐French endemism also sequenced for this study. Owing to the priority of Orodrilus, Iberoscolex should be considered a junior synonym, with all of the species formerly included within it assigned to a redefined Orodrilus. Strong population structure was observed for Iberoscolex and Castellodrilus species under study, together with a pattern of isolation by distance; however, these genera showed different patterns of genetic variability: the Castellodrilus species under study exhibit lower genetic diversity, with fewer haplotypes per population than the Iberoscolex species.

Three species of mussels collected from fresh‐ and low salinity (10 psu or lower) brackish‐water environments in southern Thailand, Singapore, northern Borneo and south Sulawesi formed a new, well‐supported and distinct mytilid clade based on molecular phylogeny. All are small (< 30 mm) species with either radially ribbed or smooth shells. Internally, the upper edges of the ascending lamellae of the outer and inner demibranchs are, respectively, fused to the mantle lobes and visceral mass. A new genus Parabrachidontes is proposed to accommodate the three species. Of the species in the new genus, one is described as new (Parabrachidontes amnicus sp. n.), and the other two poorly known species (P. leucostictus and P. cochinensis) are re‐described. The Parabrachidontes clade is closely related to Mytella, Perna and Arcuatula. Together, they formed a well‐supported clade, most members of which have ctenidial edges attached to the mantle and/or visceral mass. These genera are clearly distinct phylogenetically from two other mytilid clades containing brackish‐ and fresh‐water species with ctenidia free of the mantle: one comprising the genera Limnoperna and Sinomytilus (together constituting the Limnoperninae), and the other Xenostrobus and Vignadula (forming the Xenostrobinae). We therefore suggest the existence of at least three lineages of mytilids living in rivers and estuaries of East Asia and Australasia.

The Asian pitviper genus Ovophis is a group of venomous snakes widely distributed in mid to high elevation mountains in Asia, and presently five species are recognised. However, its systematics, species diversity and species distribution boundaries remain poorly understood. We reconstructed the phylogenetic relationships and explored species diversity of Chinese Ovophis based on two mitochondrial fragments (Cyt b and ND4) and four nuclear genes (BACH1, c‐mos, Rag1, NT3) and also conducted a morphological comparison between focal species. Our results indicated that the species diversity had been underestimated within Ovophis and we described a population from southern Yunnan, China, as a new taxon, naming it as Ovophis malhotrae sp. nov. Based on more extensive sampling, we redefined the distribution of O. monticola and O. makazayazaya in China. Divergence date estimation suggested that Ovophis originated at about 16.79 Ma in the middle Miocene.
