ABSTRACT The insect order Hemiptera, one of the best-studied insect lineages with respect to bacterial symbioses, still contains major branches that lack comprehensive characterization of associated bacterial symbionts. The Pyrrhocoroidea (Largidae [220 species] and Pyrrhocoridae [∼300 species]) is a clade of the hemipteran infraorder Pentatomomorpha. Studies on bacterial symbionts of this group have focused on members of Pyrrhocoridae, but recent examination of species of two genera of… 
Characterization of a novel Pantoea symbiont allows inference of a pattern of convergent genome reduction in bacteria associated with Pentatomidae.
TLDR
A novel Pantoea species was characterized from the gut of pentatomid Acrosternum arabicum, and shown to be highly abundant in a specific portion of the gut and necessary for the host development, highlighting a convergent pattern of genome reduction in symbionts ofpentatomids.
Deep Instability in the Phylogenetic Backbone of Heteroptera is Only Partly Overcome by Transcriptome-Based Phylogenomics
TLDR
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.
Genomic Comparison of Insect Gut Symbionts from Divergent Burkholderia Subclades
TLDR
A “symbiotic island” in the genome of stink bug-associated Burkholderia is suggested, with all previously reported symbiosis factors are shared and that 282 genes are specifically conserved in the five stink bug symbionts, over one-third of which have unknown function.
Phylogenomic analysis suggests Coreidae and Alydidae (Hemiptera: Heteroptera) are not monophyletic
TLDR
The utility of phylogenomic approaches in generating robust hypotheses for taxa with long‐standing phylogenetic problems and the importance of a robust phylogeny for evolutionary hypothesis testing are demonstrated and novel insights may come from such approaches.
Cladogenesis and Genomic Streamlining in Extracellular Endosymbionts of Tropical Stink Bugs
TLDR
This study completely sequenced the genomes of the uncultivable bacterial symbionts of four neotropical stink bugs of the Edessa genus and proposed the candidate name “Candidatus Pantoea edessiphila” for the species of these symbiontes with strain designations according to their host species.
Revisiting habitat and lifestyle transitions in Heteroptera (Insecta: Hemiptera): insights from a combined morphological and molecular phylogeny
TLDR
The results indicate that aquatic and semi‐aquatic true bugs invaded these habitats three times independently from terrestrial habitats in contrast to a recent hypothesis, and suggest that the most recent common ancestor of Heteroptera was predacious.
Geographic Variation of Bacterial Communities Associated with Cotton Fleahopper, Pseudatomoscelis seriatus1
TLDR
Characterization of the P. seriatus bacterial microbiota showed it was distinct from other well-characterized hemipteran herbivores, and whether variation in microbiota corresponds with variation in traits relevant to pest control warrants further investigation.
The importance of environmentally-acquired bacterial symbionts for the squash bug (Anasa tristis), a significant agricultural pest
TLDR
It is demonstrated that complete understanding of the squash bug and Anasa tristis requires consideration of their association with bacterial symbionts in the family Burkholderiaceae, which are closely related to Caballeronia spp.
The Importance of Environmentally Acquired Bacterial Symbionts for the Squash Bug (Anasa tristis), a Significant Agricultural Pest
TLDR
It is demonstrated that complete understanding of the squash bug and Anasa tristis requires consideration of their association with bacterial symbionts in the family Burkholderiaceae, and that the association can significantly increase survival and decrease development time.
Angiosperm to Gymnosperm host‐plant switch entails shifts in microbiota of the Welwitschia bug, Probergrothius angolensis (Distant, 1902)
TLDR
A dynamic gut microbiota may provide a means for insect adaptation to new host plants in new environments when food plants are extremely divergent, as well as indicating potential host‐specialized nutritional roles.

Symbiosis and Insect Diversification: an Ancient Symbiont of Sap-Feeding Insects from the Bacterial Phylum Bacteroidetes
TLDR
It is shown that the large group of related insects including cicadas, leafhoppers, treehopper, spittlebugs, and planthoppers host a distinct clade of bacterial symbionts, belonging to the phylum Bacteroidetes.
Evolutionary transition in symbiotic syndromes enabled diversification of phytophagous insects on an imbalanced diet
TLDR
The change in symbiotic syndromes and the acquisition of the pyrrhocorid core microbiota followed the evolution of their preferred host plants (Malvales), suggesting that the symbionts facilitated their hosts’ adaptation to this imbalanced nutritional resource and enabled the subsequent diversification in a competition-poor ecological niche.
An ancient but promiscuous host–symbiont association between Burkholderia gut symbionts and their heteropteran hosts
TLDR
Molecular phylogenetic analysis showed that the gut symbionts of the lygaeoid and coreoid stinkbugs belong to a β-proteobacterial clade together with Burkholderia isolates from soil environments and Burk holderia species that induce plant galls, indicating host–symbiont promiscuity among these stinkbugs.
Burkholderia of Plant-Beneficial Group are Symbiotically Associated with Bordered Plant Bugs (Heteroptera: Pyrrhocoroidea: Largidae)
TLDR
It is demonstrated that the largid species are consistently associated with the “plant-associated beneficial and environmental (PBE)” group of Burkholderia, which are phylogenetically distinct from the SBE group, and that they maintain symbiosis through the environmental acquisition of the bacteria.
Geographical and ecological stability of the symbiotic mid‐gut microbiota in European firebugs, Pyrrhocoris apterus (Hemiptera, Pyrrhocoridae)
TLDR
It is suggested that the firebug mid‐gut microbiota constitutes a functionally important and possibly coevolved symbiotic community.

TLDR
The results indicate that the aquatic and semi‐aquatic true bugs evolved under environmental conditions of high air temperature and humidity in an evolutionary scenario similar to that of the aquatic holometabolans.
Evolution of symbiotic organs and endosymbionts in lygaeid stinkbugs
TLDR
The evolution of bacteriomes and endosymbionts in the Heteroptera is discussed, most members of which are associated with gut symbiotic bacteria.
Diversity of bacterial endosymbionts and bacteria-host co-evolution in Gondwanan relict moss bugs (Hemiptera: Coleorrhyncha: Peloridiidae).
TLDR
The first molecular identification of the bacteriome-associated, obligate endosymbiont in a Gondwanan relict insect taxon, the moss bugs (Hemiptera: Coleorrhyncha: Peloridiidae), which represents one of the oldest lineages within the Hemiptera.
Actinobacteria as essential symbionts in firebugs and cotton stainers (Hemiptera, Pyrrhocoridae).
TLDR
Fitness of symbiont-deprived bugs could be completely restored by re-infection with the original microbiota, while reciprocal cross-infections of microbial communities across both pyrrhocorid species only partially rescued fitness, demonstrating a high degree of host-symbiont specificity.
Comparative mitogenomic analysis of the superfamily Pentatomoidea (Insecta: Hemiptera: Heteroptera) and phylogenetic implications
TLDR
This comparative mitogenomic analysis sheds light on the architecture and evolution of mitogenomes in the superfamily Pentatomoidea and shows thatMitogenomes can be effectively used to resolve phylogenetic relationships of pentatomomorphan insects at various taxonomic levels.
