However, crickets, the third largest group of this order, have notably smaller genomes than grasshoppers or katydids. The evolutionary drivers behind these differences in genome size (GS) remain largely uncharted. In our study involving 56 cricket species, we assessed GS using flow cytometry and assembled 43 novel mitochondrial genomes for phylogenetic analysis. Model fitting indicated that GS generally conformed to an Ornstein-Uhlenbeck adaptive evolutionary model, displaying a 5.1-fold range of variation in GS, from 0.82 pg in <i>Myrmecophilus quadrispina</i> Perkins to 4.68 pg in <i>Ornebius formosanus</i> Shiraki. Remarkably, despite such variations, no significant trends in genome contraction or expansion were detected, suggesting an adaptive stabilisation. We found strong evidence that expansions of repeat elements, particularly transposable elements (TEs), are key drivers of the large GS in crickets. Across the 56 cricket species analysed, TE content exhibited substantial variability, spanning from a mere 3.63% to a pronounced 31.22%. Clades exhibiting significant GS or TE variations, such as mole crickets (Gryllotalpidae), ant-loving crickets (Myrmecophilidae) and scaly crickets (Mogoplistidae), are often observed at basal phylogenetic nodes and exhibit distinct ecological niches and morphological divergences. This implies that cricket genomes undergo early mutations and stabilise throughout evolution. Our findings shed light on common patterns and uncover lineage-specific differences in content and evolution of TEs in crickets. We anticipate that our study will provide a foundation for future comparative research on the insect TE repertoire.</p>","PeriodicalId":22126,"journal":{"name":"Systematic Entomology","volume":null,"pages":null},"PeriodicalIF":4.7,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140071095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the internal parts of the genitalia of a male fossil cricket from Cretaceous amber, †<i>Picogryllus carentonensis</i> Josse &amp; Desutter-Grandcolas (Oecanthidae, Podoscirtinae), together with other key morphological characters (i.e., metanotal structures and tibial spurs), were reconstructed for the first time by 3D microtomography.

Divergence time estimates were thus refined and the patterns of transformation for key morphological structures contrasted through the analysis of phylogenetic morphological partitions. Our results show that Oecanthidae date back to the Upper Jurassic (Oxfordian, around 162 Ma) and attest to the presence of the Podoscirtinae in Western Europe during the Lower Cretaceous.

In recent years, the advent of next-generation sequencing has significantly reduced the challenges of obtaining considerable genetic information from historical museum specimens. Crickets in the Australian tribe Eurepini Robillard are a good example of a taxon in which such museomic data have particularly strong potential to advance systematic knowledge, because comprehensive sampling requires decades of work over a very wide area. The tribe currently comprises 64 described species in five genera. Previous studies conflict in the generic relationships inferred for this tribe, all of which are poorly resolved, being based on limited data and sampling. In addition, there has so far been no systematic research for this tribe with extensive taxon sampling, and therefore, the consequence for genus boundaries remains to be investigated. To investigate phylogenetic relationships within Eurepini, we first applied the genome skimming approach to obtain molecular data from a comprehensive sample of Eurepini museum specimens. Of the 69 specimens sampled representing 61 described species, mainly including holotype specimens, we obtained 50 complete and 11 partially complete mitogenomes. Three nuclear genes (H3, 18S, and 28S) were also partially recovered for nearly all of these specimens. Phylogenetic analyses performed with mitogenomes plus three nuclear genes using maximum likelihood and Bayesian inference generated well-supported and highly congruent topologies. Eurepini was strongly recovered monophyletic with eight well-defined groups. These groups are used to revise the systematics of the tribe based on a combination of molecular phylogenetics and morphology.

The maximum likelihood (ML) and Bayesian inference (BI) analyses strongly support the monophyletic clade including Cicadellinae and Phereurininae.

The earliest divergence during the Cretaceous gave rise to Oriental and New World lineages, the latter of which subsequently dispersed into the Old World and gave rise to the diverse endemic fauna of Madagascar. The Oriental lineage shows high diversity and endemism in tropical Asia and the Pacific, with striking distributional discontinuities in Wallacea.

We investigate the evolutionary history of Haloveliinae using large-scale phylogenomic datasets and a set of novel redefined morphological characters based on 24 ingroup taxa representing all recognized genera. Our phylogenetic results based on the novel datasets definitively indicate that the freshwater genus <i>Strongylovelia</i> Esaki as currently defined is paraphyletic and supports the establishment of a new genus: <i>Metavelia</i> gen. nov., including three congeneric species: <i>Metavelia patiooni</i> comb. nov.

This time coincides with the period of high global sea levels in the Late Cretaceous. During this period, the marine incursions caused by the massive sea level rise flooded the continental margins, especially in Southeast Asia, where ancestral Haloveliinae were probably distributed.
