Gene Selection and Evolutionary Modeling Affect Phylogenomic Inference of Neuropterida Based on Transcriptome Data
International journal of molecular sciences, 2019Co-Authors: Yuyu Wang, Ding Yang, Xingyue Liu, Xiaofan Zhou, Liming Wang, Antonis RokasAbstract:Neuropterida is a super order of Holometabola that consists of the orders Megaloptera (dobsonflies, fishflies, and alderflies), Neuroptera (lacewings) and Raphidioptera (snakeflies). Several proposed higher-level relationships within Neuropterida, such as the relationships between the orders or between the families, have been extensively debated. To further understand the evolutionary history of Neuropterida, we conducted phylogenomic analyses of all 13 published transcriptomes of the neuropterid species, as well as of a new transcriptome of the fishfly species Ctenochauliodes similis of Liu and Yang, 2006 (Megaloptera: Corydalidae: Chauliodinae) that we sequenced. Our phylogenomic data matrix contained 1392 ortholog genes from 22 holometabolan species representing six families from Neuroptera, two families from Raphidioptera, and two families from Megaloptera as the ingroup taxa, and nine orders of Holometabola as outgroups. Phylogenetic reconstruction was performed using both concatenation and coalescent-based approaches under a site-homogeneous model as well as under a site-heterogeneous model. Surprisingly, analyses using the site-homogeneous model strongly supported a paraphyletic Neuroptera, with Coniopterygidae assigned as the sister group of all other Neuropterida. In contrast, analyses using the site-heterogeneous model recovered Neuroptera as monophyletic. The monophyly of Neuroptera was also recovered in concatenation and coalescent-based analyses using genes with stronger phylogenetic signals [i.e., higher average bootstrap support (ABS) values and higher relative tree certainty including all conflicting bipartitions (RTCA) values] under the site-homogeneous model. The present study illustrated how both data selection and model selection influence phylogenomic analyses of large-scale data matrices comprehensively.

RESEARCH ARTICLE Wing Base Structural Data Support the Sister Relationship of Megaloptera and
2016Co-Authors: Neuroptera Neuropterida, Chenjing Zhao, Xingyue Liu, Ding YangAbstract:The phylogenetic status and the monophyly of the holometabolous insect order Megaloptera has been an often disputed and long unresolved problem. The present study attempts to infer phylogenetic relationships among three orders, Megaloptera, Neuroptera, and Raphidioptera, within the superorder Neuropterida, based on wing base structure. Cladistic analyses were carried out based on morphological data from both the fore- and hindwing base. A sister relationship between Megaloptera and Neuroptera was recovered, and the monophyly of Megaloptera was corroborated. The division of the order Megaloptera, the traditional higher classification, into Corydalidae (Corydalinae + Chauliodinae) and Sialidae, was also supported by our wing base data analyses

Homology of the genital sclerites of Megaloptera (Insecta: Neuropterida) and their phylogenetic relevance
Systematic Entomology, 2015Co-Authors: Xingyue Liu, Ding Yang, Horst Aspöck, Ulrike AspöckAbstract:The genitalia of Megaloptera are crucial for taxonomic identification and represent a significant component of characters for phylogenetic interpretation of this order. However, several complex genital structures, especially those related to segments 9 and 11 in Megaloptera, have yet to be subjected to a comprehensive survey of homology. The terminology for genital sclerites has been variously and even incorrectly used by different authors, a fact which could lead to much confusion about character evolution. In this paper, we first present a comprehensive morphological comparison of the sclerites of male and female genital segments in 23 Megalopteran genera representing all major lineages of Corydalinae, Chauliodinae and Sialidae. Accordingly, we then provide new interpretations on the homology of the genital sclerites which often appear to be considerably different among Megaloptera. Based on our new and revised homology assessments, we conclude that: (i) the small to medium-sized sclerite beneath the ectoprocts in males of Sialidae represents the fused gonocoxites 11; (ii) the male gonocoxites 11 in Corydalidae are largely reduced and are sometimes retained as a small sclerite beneath the anus; (iii) the predominant sternite-like sclerite of the female abdominal segment 8 represents the fused gonocoxites 8; and (iv) a pair of sclerites amalgamated with the lateral arms of male gonocoxites 10 in Chauliodinae is the gonocoxites 9. Furthermore, based on our genital homology assessments, we reconstruct an intergeneric phylogeny including all genera of Megaloptera using genital characters in a parsimonious analysis to test their phylogenetic relevance. The phylogeny herein recovered is largely congruent with the results from several previous studies, thus underlying the significant phylogenetic relevance of the Megalopteran genital sclerites. The present work provides new insights into the evolution of insect genitalia.

A new fishfly species (Megaloptera: Corydalidae: Chauliodinae) from Eocene Baltic amber
Palaeoentomology, 2020Co-Authors: Xingyue Liu, Jörg AnsorgeAbstract:The fossil record of Megaloptera (Insecta: Holometabola: Neuropterida) is very limited. Both Megalopteran families, i.e., Corydalidae and Sialidae, have been found in the Eocene Baltic amber, comprising two named species in one genus of Corydalidae (Chauliodinae) and four named species in two genera of Sialidae. Here we report a new species of Chauliodinae from the Baltic amber, namely Nigronia prussia sp. nov.. The new species possesses a spotted hind wing with broad band-like marking, a well-developed stem of hind wing MA subdistally with a short crossvein to MP, a single straight RP branch separated between 1ra-rp and 2ra-rp in hind wing, and the hind wing A3 with anterior branch proximally touching A2. A tentative placement of the new species in Nigronia Banks, 1908, which is an extant genus endemic to eastern North America, is discussed in detail. Our finding provides new evidence indicating that the fishflies related to the extant species from eastern North America had occurred in Europe during the Early Tertiary.

First development and characterization of 27 novel microsatellite markers in the dobsonfly Neoneuromus ignobilis (Megaloptera: Corydalidae) at genome-scale level
Applied Entomology and Zoology, 2020Co-Authors: Aili Lin, Wei Shujun, Li-jun Cao, Xingyue LiuAbstract:The dobsonfly species Neoneuromus ignobilis Navas (Megaloptera: Corydalidae) is endemic to but widely distributed from eastern and southeastern Asia, being an important insect indicator for freshwater biomonitoring. At present, there is no report on the development of microsatellites of Megaloptera. Here, we developed 27 novel microsatellite markers of N. ignobilis from 850,920 candidate microsatellites with the stringent screening criteria considering the amplification success rate, the presence or absence of stutter peaks, the peak intensity, the polymorphism of the loci, the heterozygosity, and the number of alleles. The allele number of 27 microsatellite markers ranges from 3 to 12 with an average value of 6.19 per locus. The observed heterozygosity (HO) and expected heterozygosity (HE) revealed a range from 0.000 to 0.947 and 0.000 to 0.842, respectively. We constructed three panels (MP panel, most polymorphic; SS panel, most stringent strategy; ALL panel, total 27 microsatellite markers) and compared the analyses on population genetic diversity and structure. The result showed that the MP panel can significantly improve the analyses of individual assignment and genetic diversity. Accordingly, we advocate selecting the most polymorphic microsatellite marker for analyzing population genetics based on microsatellite data. The present work represents the first study on the microsatellite development of Megaloptera.

First record of Chironomidae larvae (Insecta, Diptera) as prey of Temnocephala (Platyhelminthes, Temnocephalidae), an ectosymbiont on Corydalidae larvae (Megaloptera).
Revista Brasileira De Entomologia, 2012Co-Authors: Susana Trivinho-strixino, Fabio Laurindo Da Silva, Francisco Valente-netoAbstract:First record of Chironomidae larvae (Insecta, Diptera) as prey of Temnocephala (Platyhelminthes, Temnocephalidae), an ectosymbiont on Corydalidae larvae (Megaloptera). We registered first time Temnocephala Blanchard, ectosymbiont on Corydalidae, as a predator of Chironomidae larvae. We examined 28 Corydalidae larvae (Corydalus and Protochauliodes) under stereomicroscopic in search for Temnocephala and Chironomidae larvae attached on it. We found 24 temnocephalan attached on five Megalopteran larvae body. Furthermore, eight Temnocephala exhibited chironomid larvae in their gut contents, interaction unknown previously. Gut content analysis revealed the most abundant taxon was Corynoneura, and also larvae of Larsia, Rheotanytarsus and Tanytarsus were recorded as well. This study included Corydalus and Protochauliodes as new hosts of Temnocephala, which might be important for their dispersion and population dynamic.
