The Chironomidae (Diptera), or non-biting midges, of Illinois have been untreated since the early 20th century, and the high level of taxonomic flux in the family necessitates an update, particularly for a group with importance as bio-indicators of freshwater ecosystem health. Herein, 181 species of Chironomidae in 76 genera are recorded from the s...

We describe a new Eocene fossil assassin bug, Aphelicophontes danjuddi gen. et sp. nov. (Reduviidae: Harpactorinae), from the Green River Formation of Colorado. The specimens informing this description are extraordinarily preserved, particularly in the external and internal structures of the adult male genitalia. We discuss implications of the new...

It is no secret that fossilization can be a fickle process, being strongly influenced by a number of abiotic (e.g., habitat, oxygen level, isolation from other organisms, deposition, land disturbance, type of fossilization) and biotic (e.g., skeletal type, size of organism, life stage, population size) factors (e.g., Zherikhin, 2002). It also is a...

The fossil heteropteran Miocoris fagi Cockerell, 1927 stat. rev. is redescribed and transferred from Reduviidae to the nominate tribe in Nabidae. The fossil Nabidae are surveyed and enumerated. One taxon, Sinanabis brevipes Zhang, 1986 stat. rev., is removed from Nabidae and is considered incertae familiae.

Knowledge of the biodiversity of a region can have wide-ranging implications for other disciplines and enterprises, including public health, agriculture and pest management, and conservation. However, in order to properly assess a region’s biodiversity, an accurate and up-to-date taxonomy is needed.While description of new taxa plays a sizeable rol...

The purpose of this note is to review the usage of the generic names Parsialus Stål, 1863 and Homalosphodrus Stål, 1867 (type species: Parsialus depressus Stål, 1863) for a genus of harpactorine assassin bugs from the Oriental Region, the latter apparently being an unnecessary replacement name proposed for the former. Although Parsialus Stål, 1863...

Herein are erected several new taxa and taxonomic changes based on a study of the Old World genera of Peiratinae: Sphodrembas gen. nov. is erected for a single new species, Sphodrembas fumipennis sp. nov. from Kenya and Tanzania. Ectomocoris caccabatus sp. nov. is newly described and represents the first record of the genus from the Korean Peninsul...

Heteroptera is a diverse suborder of insects that includes many plant pests, human disease vectors, and nuisance pests, but also beneficial insects. Previous analyses have supported recognition of seven monophyletic infraorders. A clade comprising Leptopodomorpha, Pentatomomorpha, and Cimicomorpha is also well-accepted, but relationships among the...

Alabama is one of the most speciose states in the United States, yet many common groups of organisms, including assassin bugs (Hemiptera: Heteroptera: Reduviidae), have yet to be fully documented. The purpose of this manuscript is to identify all known assassin bug species occurring in the state using literature records and specimens from natural h...

Additionally, the phymatine species currently known from...

The purpose of this note is to review the usage of the generic names Cutocoris Stål, 1859 and Cydnocoris Stål, 1866 (type species: Myocoris gilvus Burmeister, 1838) for a genus of harpactorine assassin bugs from the Oriental Region, the latter being an unnecessary replacement name proposed for the former. Although Cutocoris Stål, 1859 has been used...

Hemipteroid insects (Paraneoptera), with over 10% of all known insect diversity, are a major component of terrestrial and aquatic ecosystems. Previous phylogenetic analyses have not consistently resolved the relationships among major hemipteroid lineages. We provide maximum likelihood-based phylogenomic analyses of a taxonomically comprehensive dat...

Rasahus castaneus Coscarón, 1983 is reported for the first time from Fre...

The purpose of the present notice is to identify and clarify a case of mistaken homonymy surrounding the name Argolis, pertaining to Lepidoptera, Hemiptera, and Coleoptera. It is here demonstrated that “Argolis” (Boisduval 1836: 2) is an incorrect original spelling of Ergolis Boisduval, 1836 (Lepidoptera: Nymphalidae); therefore, Argolis Stål, 1861...

Assassin bugs (Reduvioidea) are one of the most diverse (>7,000 spp.) lineages of predatory animals and have evolved an astounding diversity of raptorial leg modifications for handling prey. The evolution of these modifications is not well understood due to the lack of a robust phylogeny, especially at deeper nodes. We here utilize refined data fro...

The monotypic genus Horciniella Miller, 1958 is considered a junior synonym of Archilestidium Breddin, 1900 (new synonymy), resulting in the following taxonomic change for its type species: Archilestidium variabile (Miller, 1958) (new combination). The evidence supporting this conclusion and the new composition of the genus are discussed at length....
