Molecular and morphological approaches redefine the limits among polymorphic species in the Neotropical longhorn beetle genus, Myzomorphus Sallé (Coleoptera: Cerambycidae: Prioninae).

Myzomorphus Sallé is a charismatic genus of prionine longhorn beetles (Cerambycidae) composed of nine species. Myzomorphus species are found from Costa Rica to southern Brazil, but only two species have wide distributions across this range: M. scutellatus Sallé from Costa Rica to northern Brazil, and M.

Synopsis of the genus Pseudocriopsis (Insecta: Coleoptera: Cerambycidae).

A synopsis of the flat-faced longhorned beetle genus Pseudocriopsis Melzer, 1931 is presented. Pseudocriopsis abare sp. nov.

Checklist of the Lamiinae (Coleoptera, Cerambycidae) of the Taxonomic Collections Center of the Federal University of Minas Gerais (Brazil).

The Taxonomic Collections Center of the Federal University of Minas Gerais (CCT-UFMG) has 223,653 insects catalogued, of which about 6,500 are beetles (Coleoptera). Most insects in the collection are from the southeastern region of Brazil. The collection also includes specimens from other regions and from other countries.

New species of Chaetonerius Hendel (Diptera: Neriidae) and key for identification of the Neriidae of Tanzania.

Chaetonerius Hendel is the only native genus of Neriidae from the African continent, with 21 species described. Although widely distributed across the Afrotropical region, the species of Chaetonerius are still poorly known and recent efforts are being devoted to clarify the taxonomy of the family and discover its diversity. Here, we describe a new neriid species from Tanzania, Chaetonerius stichodactylus sp.

Molecular phylogenetic assessment of the tribal classification of Lamiinae (Coleoptera: Cerambycidae).

Lamiinae is the most diverse subfamily of longhorned beetles, with about 20,000 described species classified into 80 tribes. Most of the tribes of Lamiinae were proposed during the 19th century and the suprageneric classification of the subfamily has never been assessed under phylogenetic criteria. In this study, we present the first tribal-level phylogeny of Lamiinae, inferred from 130 terminals (representing 46 tribes, prioritizing generic type species of the tribes) and fragments of two mitochondrial and three nuclear markers (cox1, rrnL, Wg, CPS and LSU; 5,024 aligned positions in total).

A new species of Chaetonerius Hendel (Diptera: Neriidae) from Northeast Madagascar.

A new species of Ethiopian Neriidae, Chaetonerius serratus sp. n., is described from Madagascar.

A new species of Colobothea Lepeletier & Audinet-Serville, 1825 (Coleoptera: Cerambycidae: Lamiinae) from Ecuador.

Colobotheini is a tribe of Lamiinae (Cerambycidae) which includes 189 species classified into 12 genera (Monné, 2016). This tribe is characterized by a trapezoidal frons, contiguous antennal tubercles, prothorax without lateral spines, elytra elongate with lateral carina, metatarsomere I elongate and tarsal claws divaricate (Galileo & Martins, 2006). Colobothea Lepeletier & Audinet-Serville, 1825 is the largest genus of Colobotheini, with 119 valid species distributed from Mexico to Southern South America, except Chile and latitudes below 35°S.

Revision of the genus Ateralphus Restello, Iannuzzi & Marinoni, 2001 (Coleoptera: Cerambycidae: Lamiinae).

A revision of the genus Ateralphus Restello, Iannuzzi & Marinoni, 2001, based on the detailed study of the morphology of the type-species and on the external morphology and terminalia of the others species is presented. The genus and species are redescribed and three new species are described. The genus is composed of nine species: A.
