Background Spiders comprise a hyperdiverse lineage of predators with venom systems, yet the origin of functionally novel spider venom glands remains unclear. Previous studies have hypothesized that spider venom glands originated from salivary glands or evolved from silk-producing glands present in early chelicerates. However, there is insufficient molecular evidence to indicate similarity among them. Here, we provide comparative analyses of genome and transcriptome data from various lineages of spiders and other arthropods to advance our understanding of spider venom gland evolution. Results We generated a chromosome-level genome assembly of a model spider species, the common house spider (Parasteatoda tepidariorum). Module preservation, GO semantic similarity, and differentially upregulated gene similarity analyses demonstrated a lower similarity in gene expressions between the venom glands and salivary glands compared to the silk glands, which questions the validity of the salivary gland origin hypothesis but unexpectedly prefers to support the ancestral silk gland origin hypothesis. The conserved core network in the venom and silk glands was mainly correlated with transcription regulation, protein modification, transport, and signal transduction pathways. At the genetic level, we found that many genes in the venom gland-specific transcription modules show positive selection and upregulated expressions, suggesting that genetic variation plays an important role in the evolution of venom glands. Conclusions This research implies the unique origin and evolutionary path of spider venom glands and provides a basis for understanding the diverse molecular characteristics of venom systems.

Sea–land transition caused by marine incursion and regression is hypothesized to be a major driving force in terrestrial biodiversity, providing opportunities for marine ancestors to colonize terrestrial habitats and driving vicariant speciation in distinct geographical regions. Here, we test this hypothesis in East Asia using amphipods of the Morinoia japonica complex. We constructed a dataset from 269 individuals covering all known ranges of this species complex. Phylogenetic and biogeographic analyses revealed that sea–land transition during the Miocene drove the coastal ancestor to invade terrestrial habitats in East Asia and subsequently split into eight biogeographic lineages in eastern China, Korea, Japan and some Pacific islands. Stepping-stone dispersal resulted in a relatively wide distribution of M. japonica, and long-term geographical isolation led to the diversification of the M. japonica complex. Species delimitation analysis suggests that this complex contains eight species. We describe the geographical group from eastern China as a new species, Morinoia aosen sp. nov., based on genetic and morphological comparisons with other geographical groups. Type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS) in Beijing, China.

Cenozoic tectonic evolution in the Tethyan region has greatly changed the landforms and environment of Eurasia, driving the evolution of animals and greatly affecting the diversity patterns of Eurasian animals. By combining the latest Tethyan paleogeographic models and some recently published Eurasian zoological studies, we systematically summarize how tectonic evolution in the Tethyan region has influenced the evolution and diversity patterns of Eurasian animals. The convergence of continental plates, closure of Tethys Sea, and Tethyan sea-level changes have directly affected the composition and spatial distribution of Eurasian animal diversity. The topographic and environmental changes caused by Tethyan tectonics have determined regional animal diversity in Eurasia by influencing animal origin, dispersal, preservation, diversification, and extinction. The ecological transformations resulted in the emergence of new habitats and niches, which promoted animal adaptive evolution, specialization, speciation, and expansion. We highlight that the Cenozoic tectonic evolution of the Tethyan region has been responsible for much of the alteration in Eurasian animal distribution and has been an essential force in shaping organic evolution. Furthermore, we generalize a general pattern that Tethyan geological events are linked with Eurasian animal evolution and diversity dynamics.特提斯海区域新生代以来的构造演化极大地改变了欧亚地区的地貌和环境,推动了欧亚地区的动物演化,并深刻影响了欧亚地区的动物多样性格局。该文通过结合最新的特提斯海区域古地理模型,对近期发表的一系列欧亚地区动物学研究进行系统回顾和总结,详细论述了特提斯海区域新生代以来的构造演化是如何影响欧亚地区动物的演化及多样性格局的:大陆板块的汇聚、特提斯海的闭合以及特提斯海区域海平面变化直接影响了欧亚地区的动物多样性组成和空间分布;海陆变迁引起的区域地理和环境变化,对当地动物的起源、扩散、存留、多样化和灭绝产生了一系列影响,进而决定了欧亚动物的区域多样性格局;生态环境的变化导致了新栖息地和新生态位的出现,促进了欧亚动物的适应性进化、特化、物种形成和扩张。我们强调了特提斯海区域新生代构造演化是欧亚动物分布变化的主要原因,也是驱动欧亚动物演化的重要力量。此外,我们提出了特提斯地质事件与欧亚动物演化和多样性动态相关的一般模式。.

Volcano-tectonic processes have been viewed as primary drivers in the formation of present-day diversity. Volcanos associated with mountain uplifts drive allopatric speciation through vicariance and may impact the surrounding areas like species pump or species attractor. However, the application of these hypotheses to aquatic fauna has rarely been tested explicitly. We tested these hypotheses in the Changbai Mountains (Mts), which are one of the most typical, active volcanic ranges in Northeast (NE) Asia with a long and turbulent geological history. The Gammarus nekkensis species complex of amphipod crustaceans, widely distributed throughout NE Asia with poor dispersal abilities and a long evolutionary history, is a suitable model for testing hypotheses of species pump or species attractor. Phylogenetic and ancestral range reconstructions demonstrated that the studied amphipod originated from the Changbai Mts ~27 Ma and diverged into eastern (Clade I) and western (Clade II) clades, which corresponds well with the initial volcanic eruption of the Changbai Mts in the Late Oligocene. The subsequent diversifications of subclades CI-3, CII-1a and CII-2a were probably driven by second and third eruptions of the Changbai Mts during the Miocene. In particular, the Changbai lineages had spread to the Russian Far East multiple times since the Early Miocene, and widely colonized the region during the Pleistocene. Our discoveries suggest that the ancient volcanos of the Changbai Mts act as species pumps in NE Asia, resulted in burst of diversification around the Changbai Mts and subsequent dispersals into adjacent regions.

Genetics ,Ecology, Evolution, Behavior and Systematics - Abstract
What happens when organisms actively modify their environment? Clarifying the role of construction behavior on a macroevolutionary scale is crucial to interpreting phenotypic evolution. Spiders, an extremely successful group of animals exhibiting a wide variety of functional, morphological, and behavioral diversity, are ideal candidates to test whether animal behaviors are related to their phenotypic evolution. Herein, we reconstructed the phylogenomic relationships of 303 spiders covering 105 families with 99 newly developed molecular markers that universally apply across Araneae, and explicitly tested the potential link between construction behavior and somatic evolution based on extensive morphological data from 3,342 extant species and 682 fossil species. Our dated molecular phylogeny provides the backbone for analyses, revealing the behavioral and ecological processes behind these spiders’ morphological adaptations. Evolutionary model analyses showed the artifacts constructed by spiders, especially the suspending webs, expand the spider’s ability to inhabit different habitats. These artifacts have more substantial impacts on their somatic traits than habitats and promote different trajectories of morphological evolution. Specifically, for spiders, silk-lined burrowing produced larger bodies, relatively shorter legs, and longer patellae, while web-building produced smaller bodies, relatively longer legs, and shorter patellae, and hunting promoted an intermediate morphological size. Molecular convergence analysis showed that genes related to morphogenesis or response to stimulus and stress are enriched in spiders with construction behavior. Our study demonstrated that the construction behavior of an animal plays a crucial role in determining the direction and intensity of the selection pressure imposed on it and provides strong evidence that construction behaviors are associated with phenotypic evolution on macroevolutionary timescales.

The Cenozoic Indian-Eurasian collision and uplift of the Himalayan-Tibetan Plateau (HTP) are among the most important geological events in the world. They have affected the diversification of regional biota of many taxonomic groups on and around the HTP. However, the exact timing and model of the collision and uplift events and speciation on and around the HTP are still in debate. The Himalayas group of Scytodes spitting spiders (Araneae: Scytodidae) are distributed at high elevations of the HTP and northern Indochina. Here, we reconstruct a dated molecular phylogeny for pan-Himalayan Scytodes spiders, including the Himalayas group, with full geographical sampling of the species from the HTP and Indochina. We test a hypothesis to explain that the rich montane biodiversity of the region is uplift-driven diversification-that orogeny drives rapid in situ speciation of the resident Scytodes lineages. Our findings revealed that the separation of the Himalayas clade from the Myanmar clade took place during the middle Oligocene, reflecting the final collision of India with Eurasia. The deep divergences among three clades (the Himalayas, the Myanmar and the Indochina clades) occurred from the middle Eocene to the middle Oligocene, corresponding to two early uplift events of the HTP. The evolutionary split between the Himalayas + Myanmar and Indochina clades were simultaneous with the rapid lateral extrusion of Indochina by the initial Himalayan uplift around the Eocene. This study highlights the importance of the diversification of dispersal-limited, high-elevation invertebrates as independent lines of evidence to reflect key tectonic events in the Himalayan-Indochina region, supporting the stepwise model for the Indian-Eurasian collision and uplift of HTP.

Although widely thought to be aggressive, solitary, and potentially cannibalistic, some spider species have evolved group-living behaviors. The distinct transition provides the framework to uncover group-living evolution. Here, we conducted a comparative transcriptomic study and examined patterns of molecular evolution in two independently evolved group-living spiders and twelve solitary species. We report that positively selected genes among group-living spider lineages are significantly enriched in nutrient metabolism and autophagy pathways. We also show that nutrient-related genes of group-living spiders convergently experience amino acid substitutions and accelerated relative evolutionary rates. These results indicate adaptive convergence of nutrient metabolism that may ensure energy supply in group-living spiders. The decelerated evolutionary rate of autophagy-related genes in group-living lineages is consistent with an increased constraint on energy homeostasis as would be required in a group-living environment. Together, the results show that energy metabolic pathways play an important role in the transition to group-living in spiders.大部分蜘蛛有攻击性,捕食同类和其他生物,营独居生活。少数营群居生活的蜘蛛,是解析生物从独居到社会性群居的重要材料。该研究基于比较转录组学,分析了2种群居蜘蛛和12种独居蜘蛛的进化模式,发现群居蜘蛛营养代谢和自噬通路基因受到正选择,与营养相关基因发生氨基酸替换和进化速率升高;发现群居蜘蛛自噬基因进化速率降低,与能量稳态的约束力增加吻合。研究结果揭示了能量代谢通路在蜘蛛从独居到社会性群居转变中的作用。.

Despite 250 years of taxonomic classification and over 1.2 million species already catalogued, known species diversity is only a small part of true species diversity on Earth, and thus, the known species are only the tip of iceberg. Here, we investigated the genus Pholcus Walckenaer, 1805 of the family Pholcidae C. L. Koch, 1850 in the Changbai Mountains, Northeast China, which provides an excellent case of high species diversity. Previously, only 14 endemic Pholcus spiders, all belonging to the P. phungiformes species group, and two introduced species P. manueli Gertsch, 1937 and P. zichyi Kulczynski, 1901 from the P. crypticolens species group, have been recorded from this area. Our study confirmed 11 new species of the P. phungiformes species group based on morphology and three methods of molecular species delimitation: P. gaizhou Yao & Li, sp. nov., P. guanshui Yao & Li, sp. nov., P. jiguanshan Yao & Li, sp. nov., P. longxigu Yao & Li, sp. nov., P. luoquanbei Yao & Li, sp. nov., P. shenshi Yao & Li, sp. nov., P. tianmenshan Yao & Li, sp. nov., P. wangjiang Yao & Li, sp. nov., P. xingqi Yao & Li, sp. nov., P. yaoshan Yao & Li, sp. nov., and P. yuhuangshan Yao & Li, sp. nov. This study brings the fauna of the P. phungiformes species group from the Changbai Mountains to 25 species, approximately two times more than previously known, which could indicate that species diversity in the area is underestimated for all arthropod fauna.

Spiders are the most abundant venomous predators in the world. Previous research related to spider venom has mostly relied on transcriptomes and proteomes, with only a few high-quality genomes available. This is far from consistent with the species diversity of spiders. In this study, we constructed a high-quality chromosome-level genome assembly of Hylyphantes graminicola, which contained 13 chromosomes, with a genome length of 931.68 Mb and scaffold N50 of 77.07 Mb. Integrating genome, transcriptome, and proteome profiling, we identified a total of 59 coding genes among nine toxin gene families. Among them, Group 7 allergen (ALL7) protein was reported in spider venom for the first time. Its coding genes had a predicted signal peptide and maintained high expression levels in the venom, suggesting that ALL7 plays an important role in venom and maybe is a type of newly discovered venom toxin in the spider. By implementing comparative genomics, we found a similar gene number of main toxin gene families in spiders and the scorpion genome with conservative evolutionary rates, indicating that these toxin genes could be an ancient (~400 million years) and a conserved "basic toolkit" for spiders and scorpions to perform primary defence functions. Obtaining high-quality chromosome-level genomes from spiders not only facilitates venom research and toxin resource application, but also can improve comparative genomic analysis in other important traits, like the evolution of silk or behaviour.

A new genus, Promolotragen. nov., including two new species, P. hponkanrazisp. nov. (♂♀) and P. shankhaungsp. nov. (♂), is described from Myanmar. The new genus is similar to Molotra Ubick & Griswold, 2011 but can be distinguished by the completely fused bulb and cymbium, the presence of a receptacle, the absence of grooves connecting either the anterior or posterior pairs of spiracles, and the incised labium of both sexes.

Biological migrations between India and Southeast (SE) Asia provide an ideal system for exploring the effects of geology and climate on species ranges. Geologists have confirmed that the direct collision between India and Eurasia occurred in the Early Eocene, but most migrations occurred between the Indian subcontinent and SE Asia rather than the former and the southern margin of Eurasia. To explain this seemingly paradoxical disconnect between the routes of plate movement and biological migration, we studied the evolutionary history of the tropical spider family Ochyroceratidae based on 101 globally distributed species. We infer a robust dated phylogeny using both transcriptomic data and a data set of classical markers and relate these to biogeographic and climatic analyses. Our results indicate that the monophyly of Ochyroceratidae is strongly supported, and the divergence times suggest a Cretaceous Gondwanan origin of the family. Reconstructed biogeographic histories support a dispersal event from the Indian subcontinent to islands of SE Asia 55–38 Ma. Climatic analyses and the fossil record reveal that ochyroceratids are characterized by a high degree of tropical niche conservatism, and that the ancestor of the Indian and SE Asian clades originated in very warm, wet environments. Early Eocene tropical, perhumid climates in India, and SE Asia may have facilitated ochyroceratid migration, whereas the dry or seasonal climate extending from the eastern coast of China to Central Asia may have acted as a barrier, preventing dispersal. Our analyses suggest that climate plays a more important role than geology in biological migration from the Indian subcontinent to SE Asia, providing new insights into the Indian–Asian biogeographic link.
