Studies in the New World tribe Anisoscelini Laporte, 1832 (Heteroptera: Coreidae: Coreinae): updated distributions, nomenclatural changes, and keys to the genera of the tribe and the species of Anisoscelis Latreille, 1829 and Bitta Osuna, 1984.

Ninety new country records are recorded for 44 species of Anisoscelini Laporte, 1832 (Heteroptera: Coreidae: Coreinae). Informal distributional records are recognized and included, and updated distributions are provided for all accounted species. The following new synonymy is proposed: Malvana Stl, 1865 (= Belonomus Uhler, 1869, n.

A new species of Champion, with taxonomic notes on other species of the genus (Hemiptera, Heteroptera, Reduviidae, Chryxinae).

from Paraguay is described, taxonomical notes on Gil-Santana, Costa & Marques, 2007 and Champion, 1899 are provided; the latter species is recorded from French Guiana for the first time; a redescription of the genus Champion, 1899 and an updated key for the genera and species of Chryxinae are presented.

Description of the new genus Tarsobaenus and three new species from Costa Rica (Coleoptera: Cleridae: Clerinae: Hydnocerini).

The new genus Tarsobaenus and three new speciesTarsobaenus letourneauae, T. piper and T. hansoniare described from Costa Rica.

Redescription of the holotype of Bostrichoclerus bicornus Van Dyke, 1938, a rare species of the New World Tillinae Fauna (Coleoptera: Cleridae), with some taxonomic notes.

Bostrichoclerus bicornus Van Dyke is known from southwest United States and northwest Mexico. To date, only two specimens have been captured: the holotype, collected on Isla Angel de la Guarda, in the Gulf of California, Mexico, and a second individual collected in San Bernardino County, California, United States. The original description of B.

Mitochondrial phylogenomics of Hemiptera reveals adaptive innovations driving the diversification of true bugs.

Hemiptera, the largest non-holometabolous order of insects, represents approximately 7% of metazoan diversity. With extraordinary life histories and highly specialized morphological adaptations, hemipterans have exploited diverse habitats and food sources through approximately 300 Myr of evolution. To elucidate the phylogeny and evolutionary history of Hemiptera, we carried out the most comprehensive mitogenomics analysis on the richest taxon sampling to date covering all the suborders and infraorders, including 34 newly sequenced and 94 published mitogenomes.

A checklist of the New World species of Tillinae (Coleoptera: Cleridae), with an illustrated key to genera and new country records.

This checklist presents the distribution of the checkered beetle subfamily Tillinae (Coleoptera: Cleridae) in the New World. Information for 164 species and 2 subspecies from 11 genera is included. The data are based on an extensive survey of material collected throughout the Americas, descriptions of new species, a number of revisionary works, data from museum specimens, as well as unpublished checklists.

Nomenclatural notes on some checkered beetle (Coleoptera: Cleridae) types of the Natural History Museum, London (BMNH).

Lectotypes were designated (and holotypes and paralectotypes recognized) for 44 species of Hydnocerinae, including the type species for Isolemidia, Parmius, Paupris, Allelidea, Blaesiopthalmus and Lemidia, four species of Enoclerus (Clerinae), and 14 species of Cymatodera (Tillinae). Annotations include comments on additional type material, new type locality, previous (type series) locality, and questionable or mysterious types. Phyllobaenus pallipes (Gorham) and P.
