“…The monophyletic Grylloidea was confirmed and the relationships within this superfamily were present as Mogoplistidae + (Trigonidiidae + (Phalangopsidae + Gryllidae)). This finding corroborates the generally accepted classification schemes [ 15 ] as well as mostly recent studies [ 8 , 17 , 18 , 39 , 40 , 76 ]. The monophyly of the superfamily Gryllotalpoidea, however, was rejected in the present study.…”

Owing to limited molecular data, the phylogenetic position of the family Gryllotalpidae is still controversial in the infraorder Gryllidea. Mitochondrial genome (mitogenome) plays a crucial role in reconstructing phylogenetic relationships and revealing the molecular evolution of insects. However, only four mitogenomes have been reported in Gryllotalpidae to date. Herein, we obtained the first mitogenomes of Gryllotalpa henana Cai & Niu, 1998 and the Chinese G. orientalis Burmeister, 1838, made a detailed comparison of all mitogenomes available in Gryllotalpidae and reconstructed the phylogeny of Gryllidea based on mitogenomes using Bayesian inference (BI) and maximum likelihood (ML) methods. The results show that the complete mitogenome sequences of G. henana (15,504 bp) and G. orientalis (15,497 bp) are conserved, both exhibiting the double-stranded circular structure, typical gene content and the ancestral insect gene arrangement. The complete mitogenome of G.henana exhibits the lowest average AT content ever detected in Gryllotalpidae, and even Gryllidea. The gene nad2 of both species has atypical initiation codon GTG. All tRNAs exhibit typical clover-leaf structure, except for trnS1 lacking the dihydrouridine (DHU) arm. A potential stem–loop structure, containing a (T)n(TC)2(T)n sequence, is detected in the control region of all gryllotalpids investigated and is likely related to the replication initiation of the minority strand. The phylogenetic analyses recover the six families of Gryllidea as Gryllotalpidae + (Myrmecophilidae + (Mogoplistidae + (Trigonidiidae + (Phalangopsidae + Gryllidae)))), similar to the trees based on transcriptomic and mitogenomic data. However, the trees are slightly different from the multilocus phylogenies, which show the sister-group relationship of Gryllotalpidae and Myrmecophilidae. The contradictions between mitogenomic and multilocus trees are briefly discussed.

“…The cluster containing Ornebius has shown variations in previous phylogenetic inferences according to the method applied ( Ma et al, 2019 ; Yang et al, 2021 ; Yu et al, 2022 ). However, our analysis strongly supported the clustering of O. fuscicercis and O. bimaculatus , with O. kanetataki as their sister group.…”

“…The inversion observed in C. rogenhoferi and M. japonica was also found in both Endecous species, confirming the position of the Phalangopsidae as a Type II ( Ma and Li, 2018 ). Additionally, we added S. punctatus of the Sclerogryllinae subfamily to this group ( Yu et al, 2022 ). Type II has been proposed to occur in the Gryllinae species, although it might be a feature of the Gryllidae family ( Yang et al, 2016 ).…”

Mitochondrial genomes have provided significant insights into the evolution of several insects. A typical mitogenome contains 37 genes, and variations in gene order can indicate evolutionary relationships between species. In this study, we have assembled the first complete mitogenomes of Endecous chape and E. onthophagus and analyzed the phylogenetic implications for the Gryllidea infraorder. We performed DNA extractions and genome sequencing for both Endecous species. Subsequently, we searched for raw data in the Sequence Read Archive (SRA) in NCBI. Using the SRA data, we assembled the partial mitogenome of Dianemobius nigrofasciatus and annotated the protein-coding genes (PCGs) for nine species. Phylogenomic relationships were reconstructed using Maximum Likelihood (ML) and Bayesian Inference (BI), utilizing the PCGs from 49 Gryllidea species. The mitogenome lengths of E. chape and E. onthophagus are 16,266 bp and 16,023 bp, respectively, while D. nigrofasciatus has a length of 15,359 bp. Our results indicate that species within the infraorder exhibit four types of gene order arrangements that align with their phylogenetic relationships. Both phylogenomic trees displayed strong support, and the ML corroborated with the literature. Gryllidea species have significantly contributed to various fields, and studying their mitogenomes can provide valuable insights into this infraorder evolution.

We report five new Myanmar amber specimens attributable to “Mole Cricket” †Pherodactylus rectanguli n. comb., hitherto regarded as a Mole Cricket (Orthoptera: Grylloptalpidae). The new material includes two adult males, two adult females, and one nymph. The specimens are redescribed, and additional new characters are provided for their delimitation and corresponding species identification. We carry out a comparison between these new specimens with other taxa of mole crickets from Myanmar amber and extant true crickets. The result indicates that some species merely represent different nymphal development stages or adults of †Pherodactylus rectanguli n. comb., however, they were misidentified as different species. We also treated genera †Tresdigitus n. syn. and †Chunxiania n. syn. as synonyms of genus †Pherodactylus Poinar, Su & Brown, 2020, and treat †Tresdigitus gracilis Jiang, Xu, Jarzembowski & Xiao, 2022 n. syn. and †Chunxiania fania n. syn. as synonyms of †Pherodactylus rectanguli n. comb. †Burmagryllotalpa longa is valid, because its shape of the pronotum curved without lateral carinae. The morphological convergences and specializations of subterranean dwelling species are discussed. The robust fore tibia and long apical spurs of †P. micromorphus, †P. rectanguli n. comb. and †B. longa are insufficient evidence for an assignment to the family Gryllotalpidae. Instead, we suggest place them into the subfamily Gryllinae (Gryllidae), tribe Sclerogryllini, and group them into their own subtribe Pherodactylina n. subtr.. A key to the identification of recent and fossil Sclerogryllini is also provided. Their taxonomy and morphology are discussed.
