Acanthosomatidae, Dinidordae, Pentatomidae, Scutelleridae, Thaumastellidae, and Urostylididae were monophyletic (under ML and MP), and also Plataspidae and Thyreocoridae (under ML). Tessaratomidae and Cydnidae were non-monophyletic under both methods. Our results were compared to the phylogenetic hypotheses proposed for Pentatomoidea. The analysis of the data available on the GenBank allowed us to affirm that many problems mentioned previously remain unsolved, even though the sampling of terminals has increased. In summary, the efforts in the last two decades to better understand the relationships within the Pentatomoidea have been insufficient to propose robust advances in phylogenetic hypothesis for the group. We discuss topics we understand are paramount to upcoming developments1) better taxon sample; 2) collection management; 3) increased markers; and 4) morphology and anatomical ontology.Based on the examination of types and additional specimens, the following new synonymies and revalidation are proposed in the genus Brontostoma Kirkaldy, 1904 (Hemiptera Heteroptera Reduviidae Ectrichodiinae) Brontostoma discus (Burmeister, 1835) = Brontostoma nanus Carpintero, 1980, syn. nov.; and Brontostoma haematodes (Blanchard, 1846), sp. reval. = Brontostoma discus nigricans Carpintero, 1980, syn. nov. The previous synonym of Brontostoma venusta (Walker, 1873) with B. discus is confirmed. Brontostoma discus is recorded from French Guiana for the first time. Brontostoma cicheroi Carpintero, 1980 is very similar to B. discus, but because its holotype was not available for study no taxonomic conclusion could be achieved.Tagalis graziae sp. nov., is described from a specimen collected in Risaralda, Colombia, in an area considered part of the Chocó biogeographic region. Among the species of Tagalis with a large and nearly horizontal posteromedial process of the pygophore, T. graziae sp. nov. can be recognized by its coloration pattern, in particular by having the profemur with a basal and apical dark brown band, the apex of the meso and metafemur with an apical narrow dark brown band, and the supracoxal lobes dark brown. Digital images of external morphological characters and of the genitalia are provided. An updated key to the species of Tagalis is presented to facilitate the identification of the new species.Four new species of the Neotropical harpactorine genus Heza Amyot Audinet-Serville are newly described Heza graziae sp. nov. from Ecuador, Heza nebrias sp. nov. from Peru and Brazil, Heza phthinica sp. nov. from Brazil and Peru, and Heza viridipes sp. nov. from Bolivia. Two new country records for two other species are also reported Heza aurantia Maldonado, 1976 from Ecuador and Heza ventralis Stål, 1872 from Brazil.A new species of Cosmoclopius Stål, 1866, C. joceliae sp. nov. is described based on specimens collected in northern Argentina. This new species is recognized by the vertical and truncate median process of pygophore, and the short-recurved spine on the apex of the dorsal phallothecal sclerite; and other features such as the dorsally black head, pronotum, and femora, and the thoracic sterna black with median pale markings; some females show lighter posterior pronotal lobe and femora with more conspicuous dark and pale bands. Digital images of the adult male and female and male genitalia are provided, as well as a comparison with the species of the genus are given.Based on specimens of Zelurus ochripennis (Stål, 1854) collected in the entrance zone of a small terrestrial cave, some biological, ecological, morphological and cytogenetic data, as well, as the general morphology of their nymphs are presented for the first time. A short taxonomic summary of the species is also provided.Two new species of Tingidae are described from Panama Acanthotingis deltoides sp. nov. and Stephanitis joceliae sp. nov. Descriptions and diagnosis for both Acanthotingis Monte and Stephanitis Stål are provided, and a key is given for the separation of the two known species of Acanthotingis. This is the first record of both genera from Panama. A checklist of all Neotropical species of both genera is presented.Hypsipyrgias joseliae sp. n. (Heteroptera Tingidae Tinginae) from New Guinea is described, illustrated and compared with its two relatives, namely H. telamonides Kirkaldy, 1908 from Australia, and H. euphues Drake and Ruhoff, 1962 from Lord Howe Island. Key to species of the genus Hypsipyrgias is also provided. Two genera very closely related to Hypsipyrgias Kirkaldy, 1908, namely Hypsotingis Drake, 1960 and Diplocysta Horváth, 1925 are re-diagnosed. Diplocysta globuliformis Hacker, 1928, D. papuana Drake, 1960, D. rustica, Drake, 1960 and D. thaleia Drake and Ruhoff, 1965 are transferred from Diplocysta to Hypsotingis.The new genus Graziaphylus is described to include two new species, Graziaphylus joceliae and G. nigripes. This new taxon is part of a large suite of Heteroptera from Australia known to feed on species of Eremophila (Scrophulariaceae), including other members of the Miridae as well as the Tingidae. The appearance of Graziaphylus spp. is similar to that of Xiphoidellus Weirauch and Schuh from Australia, and to Chlamydatus Fieber from the Northern Hemisphere (among other genera), but with scalelike setae, and elongate pulvilli adnate over most of the claw length, and the distinctive structure of the male genitalia.The new Neotropical hyaliodine Colimacoris joceliae Kim Jung, sp. nov., is described from Panama. Morphological information, including a description and diagnosis of the new species is presented with photographs. A key for the identification of the species of Colimacoris is also provided.A second species of the previously monotypic plant bug genus Campyloneura, C. joceliae sp. nov. is described based on specimens from Nkolbisson, Cameroon. A key, differential diagnoses, digital habitus images, illustrations of male and female genitalic structures, and scanning micrographs of diagnostic morphological structures are provided for the new species and C. virgula (Herrich-Schaeffer, 1835).In this paper, we present new data on the genus Macrosaldula Leston Southwood, 1964 based on material held in the collections of the National Museum (Prague, Czech Republic) and the Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia). Macrosaldula graziae sp. nov., from South Uzbekistan and Tajikistan, is described. Among the Central Asian species of the genus, it is close to M. tadzhika (Kiritshenko, 1912) by the presence of long erect setae on the body dorsum, but the latter species differs in the smaller body size, the presence of light spots on the corium, and in the structure of the male genitalia. In extremely dark specimens of M. jakowleffi (Reuter, 1891), the hemelytra are opaque, with short erect setae. Siberian M. rivularia (J. Sahlberg, 1878), M. simulans Cobben, 1985 and the Far Eastern M. koreana (Kiritshenko, 1912) and M. violacea Cobben, 1985 are distinguished from the new species by the short pubescence on the dorsum. Manogepix We provide new distributional data for M. clavalis Cobben, 1985 (Georgia), M.
