Diversification of the phytophagous lineages of true bugs (Insecta: Hemiptera: Heteroptera) shortly after that of the flowering plants

Cladistics, Journal Year: 2022, Volume and Issue: 38(4), P. 403 - 428

Published: March 29, 2022

More than 95% of phytophagous true bug (Hemiptera: Heteroptera) species belong to four superfamilies: Miroidea (Cimicomorpha), Pentatomoidea, Coreoidea, and Lygaeoidea (all Pentatomomorpha). These iconic groups highly diverse, overwhelmingly insects include several economically prominent agricultural silvicultural pest species, though their evolutionary history has not yet been well resolved. In particular, superfamily- family-level phylogenetic relationships these lineages have remained controversial, the divergence times some crucial nodes for bugs hitherto little known, which hampers a better understanding processes patterns insects. present study, we used 150 concatenated nuclear mitochondrial protein-coding genes rRNA infer within Terheteroptera (Cimicomorpha + Pentatomomorpha) estimated times. Our results support monophyly Cimicomorpha, Pentatomomorpha, Miroidea, Pyrrhocoroidea, Lygaeoidea. The across are largely congruent at deep analyses based on different datasets tree-reconstructing methods with just few exceptions. Estimated ancestral state reconstructions feeding habit indicate that explosively radiated in Early Cretaceous-shortly after angiosperm radiation-with subsequent diversification most speciose clades (Mirinae, Pentatomidae, Coreinae, Rhyparochromidae) Late Cretaceous.

The Neotropical family Phloeidae includes three species within two genera, Phloea Lepeletier and Serville, 1825 Phloeophana Kirkaldy, 1908, distributed in South America. Due to their large size notable morphological features, such as cryptic colouration, extreme body flattening lateral expansions around the body, these insects became known bark bugs. These characteristics also make them easily recognisable; nonetheless, correct identification of is still tricky, even more so for nymphs. In this work, we clarify identity species, present new diagnoses family, both genera all provide an updated key adults nymphs species. We describe illustrate chromatic variation subquadrata Spinola, 1837, high-resolution photos important diagnostic characters are provided. Literature information synthesised updated, exhaustive synonymic list provided including nomenclatural corrections: Phloeocoris paradoxus Burmeister, 1835 removed from synonymy with longirostris (Spinola, 1837) considered a junior synonym corticata (Drury, 1773); Phlaea paradoxa Signoret, 1863 longirostris.

The SSU nuclear rDNA (encoding 18S ribosomal RNA) is one of the most frequently sequenced genes in molecular analysis insects. Molecular apomorphies secondary and tertiary structures several rRNA length-variable regions (LVRs) located within V2, V4, V7 hypervariable can be good indicators for recovering monophyletic groups some heteropteran families. Among LVRs that have been analysed, LVR L V4 region longest crucial such assessments. We analysed sequences 45 species from family Cydnidae, including all 6 subfamilies (Amaurocorinae, Amnestinae, Cephalocteinae, Cydninae, Garsauriinae, Sehirinae) three pentatomoid families (Parastrachiidae, Thaumastellidae, Thyreocoridae), which often included broadly defined Cydnidae family.

The SSU nrDNA, a small subunit of the nuclear ribosomal DNA (coding 18S rRNA), is one most frequently sequenced genes in molecular studies Hexapoda. In insects, including true bugs (Hemiptera: Heteroptera), only its primary structures (i.e., aligned sequences) are predominantly used phylogenetic reconstructions. It known that RNA secondary alignment procedure essential for improving accuracy and robustness tree reconstruction. Moreover, local plasticity rRNAs might impact their tertiary corresponding functions. To determine systematic position Thaumastellidae within superfamily Pentatomoidea, and-for first time among all Hexapoda-tertiary twelve pentatomoid families were compared analysed. Results indicate shapes length-variable regions (LVRs) rRNA phylogenetically highly informative.

Protective Geometry and Reproductive Anatomy as Candidate Determinants of Clutch Size Variation in Pentatomid Bugs

The American Naturalist, Journal Year: 2023, Volume and Issue: 202(4), P. E104 - E120

Published: May 17, 2023

AbstractMany animals lay their eggs in clusters. Eggs on the periphery of clusters can be at higher risk mortality. We asked whether most commonly occurring clutch sizes pentatomid bugs could result from geometrical arrangements that maximize proportion cluster's interior. Although common do not correspond with geometric optimality, stink tend to shapes protect increasing proportions offspring as increase. also considered ovariole number, an aspect reproductive anatomy may a fixed trait across many pentatomids, explain observed distributions sizes. The species multiples number. However, there are same number ovarioles clutches widely varying size, among which overrepresented. In bugs, appears more important than egg mass geometry determining size uniformity. addition, our analysis demonstrates groups little variation nonetheless broad range and
