Species of the genus Acanthosoma Curtis, 1824 (Hemiptera: Heteroptera: Acanthosomatidae) occurring in Taiwan are reviewed. Twelve species are recognized, treated, and keyed. Four species (A. atayal sp. nov., A. axicia sp. nov., A. fallax sp. nov. and A. pugnax sp. nov.) and one subspecies (A. haemorrhoidale formosanum subsp. nov.) are described as...

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.

The Indomalayan species of the genus Alphocoris Germar, 1839 (Hemiptera: Heteroptera: Scutelleridae: Odontotarsinae: Odontotarsini) are revised. Three species, A. caudatus Rédei, Tsai & Jindra, sp. nov. (India: Maharashtra), A. naso Rédei & Tsai, sp. nov. (India: Goa), and A. asper Rédei, Tsai & Jindra, sp. nov. (India: Goa and Maharashtra), are recognized. The type material of A. lixoides Germar, 1839 (type locality: Senegal) is documented; previous records of this species from India and Pakistan are considered as based on misidentifications, the species is restricted to the Afrotropical Region.

The genus Tmetopis Kiritshenko, 1947 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae) and its type species T. chinensis Kiritshenko, 1947, distributed in central and southern China, are redescribed and illustrated. The genus is recognized as the probable sister group of Prionaca Dallas, 1851. The following new subjective synonymies and new combinations are proposed: Tmetopis chinensis Kiritshenko, 1947 = Prionaca hunanensis Lin & Zhang, 1989, syn. nov. = P. jiangxiensis Lin & Zhang, 1989, syn. nov. = P. hubeiensis Zhang, Lin & Zhao, 1990, syn. nov.; Prionaca sikkimensis (Mathew, 1969), comb. nov. (transferred from Degonetus Distant, 1902). Tmetopis (currently in Halyini) and Prionaca (currently in Pentatomini) are both transferred into the tribe Degonetini; the diagnostic characters and relationships of both genera and of the tribe are discussed.
