“…These phylogenetic results will have immense impact on our understanding of eutrichophoran morphology. For example, the resultant topology suggests open trichobothrium associated with the trichome (Gao et al., 2017; Hemala et al., 2020; Kment et al., 2019) as a synapomorphy of Eutrichophora, subsequently lost in Coreoidea (except for the Hyocephalidae) and in some Lygaeoidea lineages.…”

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

“…Larvae (n = 461) were collected during field investigations and taken to the insect laboratory of Nanjing Forestry University. The highly ossified head capsules of the larvae were removed, cleaned, and fixed on a strip of adhesive tape (Gao et al 2017). The head capsule width (HCW) and head capsule length (HCL) of each larva were measured under a Zeiss Discovery V20 stereomicroscope (Fig.…”

Cinnamomum camphora (L.) J. Presl. (Laurales: Lauraceae) is widely cultivated as an important landscape tree species in many urban areas in South China, especially in Shanghai City. Pagiophloeus tsushimanus Morimoto has become a destructive insect pest of C. camphora plantations in Shanghai, but the biological and ecological traits of this pest remain largely unknown. In this study, we investigated the damage and life history and determined the larval instar of P. tsushimanus. The results indicated that P. tsushimanus is a monophagous weevil pest, and C. camphora is the unique host tree species. C. camphora plantations in all administrative districts of Shanghai have been seriously damaged by P. tsushimanus. Adults often aggregate for feeding on the tender bark of twigs and occasionally on newly emerged buds. After experiencing damage, the twigs shrink and crack and the buds will shrink. Adults tend to repeatedly mate and oviposit, and all females lay single eggs at a time. Eggs will be covered with a mixture of secretions and wood chips by female adults. Larvae (1st–2nd instar) feed on the phloem, while 3rd–5th instar can bore into the phloem and the cambium. Massive tunnels, including three shapes (inverted “L”, inverted “T”, and inverted “Z”), were observed in the trunk of each tree, and resulted in swelling of the outer bark. P. tsushimanus has one life cycle per year in Shanghai. Both adults and larvae (3rd–5th instar) overwinter from early November to early April. Adults overwinter in grooves on the underside of branches or at branch nodes, and larvae overwinter in tunnels. Five larval instars of P. tsushimanus were determined according to Dyar's and Crosby's rules. The biological traits and life history of P. tsushimanus have been identified and can provide guidance in terms of pest control and plantation management.

“…Photomicrographs were done with Keyence VHX 5000 digital microscope, and Kern Optics OZL 466 stereoscopic microscope mounted with Kern Optics OCD 832 (5 MPix) microscope camera. Morphological terminology was adapted from Malipatil and Blackett (2013) (general morphology), Kment and Vilímová (2010) (metathoracic scent efferent apparatus), Slater (1977) (mesothoracic wing), Slater and Hurlbutt (1957) (metathoracic wing), and Gao et al (2017) (abdominal trichobothria). Genitalia were dissected and macerated as described in Kóbor (2019a).…”

The geocorine (Hemiptera: Heteroptera: Lygaeoidea: Geocoridae) true bug genus Umbrageocoris Kóbor, 2019 is redefined based on new morphological information from newly acquired specimens. Two new species are described: U. booneisp. nov. from continental Indomalaya and U. malipatilisp. nov. from Australia; two new combinations are proposed: U. elegantulus (Distant, 1904), comb. nov., and U. woodwardi (Malipatil, 1994), comb. nov. (both transferred from Geocoris Fallén, 1814). Keys, diagnoses, and distribution data to the discussed species are provided. Hypotheses on the origin of Umbrageocoris and its relationship to other geocorine genera in the region are formulated. New country records: U. elegantulus (Papua New Guinea), U. maai maai (Thailand, Laos) and U. woodwardi (Papua New Guinea).
