Second and later instars of M. sexta do not produce silk, and their spinneret and accessory labial glands (=Lyonet's glands), structures thought to be key players in silk production in other lepidopterans, are highly reduced. To our knowledge, mouthparts and labial gland morphology of the silk-producing first instar have never been described. In this study, we compared the mouthpart morphology and transcriptome profile of first and later instars of M. sexta to determine whether the loss of silk production correlates with changes in the structure of the spinneret and the labial glands, and with changes in expression of silk-related genes. We found that the first instar, unlike later instars, has a typical, silk-producing spinneret with a tube-like spigot and well developed Lyonet's glands. Moreover, three known silk protein genes are highly expressed in the first instar but exhibit little to no expression in the embryo or later instars. Thus, the changes in morphology and gene expression presented here, coinciding with changes in larval behavior from silk production to saliva spreading, further our understanding of the developmental processes underlying this transition in this model organism.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"3 1","pages":"1 - 11"},"PeriodicalIF":3.4,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/isd/ixz007","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49262220","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}

Yet, beyond broad generalities, bio- and phylogeographical patterns, and the temporal scale of diversification in the region are poorly resolved. Using one mitochondrial and one nuclear marker, we analyze intraspecific diversity patterns in a flightless, litter-inhabiting rove beetle Dasycerus carolinensis Horn. Our goals were to reconstruct the phylogeographical history of this species, producing a dated intraspecific phylogeny, and to examine previous hypotheses of possible cryptic divergence across populations of the species. Samples derive from a mix of old-growth fragments and secondary growth forests, and we also ask whether old-growth remnants host a larger proportion of genetic diversity in the species. We recover a strong primary subdivision among major lineages across the French Broad River basin (dated to ∼5.8 MYBP), and a secondary subdivision among western populations dating to ∼4.5 MYBP. Most interpopulation uncorrected divergences exceed 5%, strongly suggesting cryptic differentiation. Old-growth populations do not show greater genetic diversity than secondary-growth populations, indicating that most populations have persisted through recent anthropogenic disturbance.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"3 1","pages":"1 - 12"},"PeriodicalIF":3.4,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/isd/ixz022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43382375","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}

Previous analyses have supported recognition of seven monophyletic infraorders. A clade comprising Leptopodomorpha, Pentatomomorpha, and Cimicomorpha is also well-accepted, but relationships among the early-diverging lineages, including the aquatic infraorders (Nepomorpha and Gerromorpha), have remained poorly resolved and controversial. Phylogenomic analyses of 2,159 gene alignments derived from Illumina sequencing of transcriptomes were employed to explore the stability of relationships among major heteropteran lineages. These analyses included maximum likelihood analyses of amino acid and nucleotide sequences, as well as multi-species coalescent analysis and quartet sampling. All analyses favored a sister position of the Nepomorpha to the remaining Heteroptera. The placement of the Nepomorpha and other ambiguously supported nodes, including some within the Pentatomomorpha were explored with quartet sampling. Results of quartet sampling revealed only a slight majority of quartets supported the placement of the Nepomorpha, and some varying alternate topologies were supported within the Pentatomomorpha. These results highlight the instability of deep nodes that divide aquatic and other early-diverging lineages within the Heteroptera, suggesting that some relationships remain difficult to resolve even with large amounts of data. In addition, despite the large amount of transcriptome data analyzed, quartet sampling revealed considerable underlying conflict for some nodes, even where bootstrap support is high, emphasizing the importance of considering multiple clade support values when analyzing phylogenomic datasets.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":"3 1","pages":"1 - 14"},"PeriodicalIF":3.4,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/isd/ixz020","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41925843","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}

Recent phylogenetic analyses of the tribe have yielded conflicting results, and some have suggested a close relationship of the monobasic New Caledonian genus CompsulyxHolloway, 1979 to the Neotropical ones, despite being found on opposite sides of the Pacific Ocean. Here, we investigate relationships within the tribe using full mitochondrial genomes, mainly derived from dry-pinned museum collections material. Mitogenomic data were obtained for 19 species representing nine of the 10 Ambulycini genera. Phylogenetic trees are in agreement with a tropical Asian origin for the tribe. Furthermore, results indicate that the Neotropical genus Adhemarius Oiticica Filho, 1939 is paraphyletic and support the notion that OrectaRothschild & Jordan 1903 and TrogolegnumRothschild & Jordan, 1903 may need to be synonymized. Finally, in our analysis the Neotropical genera do not collectively form a monophyletic group, due to a clade comprising the New Caledonian genus Compsulyx and the African genus BatocnemaRothschild & Jordan, 1903 being placed as sister to the Neotropical genus ProtambulyxRothschild & Jordan, 1903. This finding implies a complex biogeographic history and suggests the evolution of the tribe involved at least two long-distance dispersal events.","PeriodicalId":48498,"journal":{"name":"Insect Systematics and Diversity","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/isd/ixz025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46913508","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}

Species diagnostics and morphological character evaluations are based on examinations of all physical specimens and virtual analyses of 3D surface models generated from micro-CT data. Additionally, we applied virtual dissections for detailed examinations of cephalic structures to establish terminology based on homology for the first time in Discothyrea.

All of the three types can be found in jumping insect legs, whereas only one type is present in grasping legs.

Two decades into the current century, the specialized biological knowledge of the history and pattern of evolution has been revolutionized by genome-scale sequencing technologies, and cryptic variation within and among species is quantifiable even with a few genetic markers. The application of statistical phylogenetic models of nucleotide and amino acid substitution to sequence data has enabled revised interpretations of morphological identities—be they population-level generalizations, such as species diagnoses, or the definition and homology of specific anatomical entities—and evolutionary transformation across the tree of life (e.g., insect genitalia, ancestral morphology of Polyneoptera). These models are also being adapted for phylogenetic analysis of morphological data, allowing explicit incorporation of fossil terminals and their stratigraphic information. In this special collection of research in Insect Systematics & Diversity (ISD), we present six papers on the topic of Current Techniques in Morphology .These papers span an arc from integrated methods of phenotype observation and visualization to methods and background for phylogenetic modeling of morphological characters.
