A global phylogeny of butterflies reveals their evolutionary history, ancestral hosts and biogeographic origins.

Butterflies are a diverse and charismatic insect group that are thought to have evolved with plants and dispersed throughout the world in response to key geological events. However, these hypotheses have not been extensively tested because a comprehensive phylogenetic framework and datasets for butterfly larval hosts and global distributions are lacking. We sequenced 391 genes from nearly 2,300 butterfly species, sampled from 90 countries and 28 specimen collections, to reconstruct a new phylogenomic tree of butterflies representing 92% of all genera.

A high-throughput multispectral imaging system for museum specimens.

We present an economical imaging system with integrated hardware and software to capture multispectral images of Lepidoptera with high efficiency. This method facilitates the comparison of colors and shapes among species at fine and broad taxonomic scales and may be adapted for other insect orders with greater three-dimensionality. Our system can image both the dorsal and ventral sides of pinned specimens.

Phanoceroides Hinton, 1939: description of new species, morphology of larvae, and revised taxonomic position of the genus (Coleoptera: Elmidae) based on molecular evidence.

The monotypic genus Phanoceroides was initially classified within the subfamily Elminae, based solely on the distribution and type of pubescence on the body surface. Although a close relationship with Larainae was suggested (Hinton 1939, Maier 2013), its taxonomic position and phylogeny remained unresolved. Based on newly collected material, we describe here P.

Hexanchorus bifurcatus sp. nov., a new tepui riffle beetle (Coleoptera: Elmidae: Larainae) from Tafelberg, Suriname.

Here we present the first published record of a laraine elmid from Suriname, which represents a new species - Hexanchorus bifurcatus sp. nov. Specimens were collected from the summit of Tafelberg, a table mountain near the Wilhelmina Range of Suriname.

Review of the Lutrochidae (Coleoptera) of the Guianas and Lesser Antilles, with description of four new species.

The species of Lutrochidae from the Guianas, and the Lesser Antilles are reviewed, including the first reports of the family from Guyana, Suriname, and Grenada. Four species are described as new: Lutrochus funkae n. sp.

A revision of the Larainae (Coleoptera, Elmidae) of Venezuela, with description of nine new species.

The species of the riffle beetle subfamily Larainae occurring in Venezuela are revised. Examination of 756 specimens yielded 22 species in nine genera occurring throughout the country. Seven species are newly recorded from the country: Phanoceroides sp.

A revision of the Lutrochidae (Coleoptera) of Venezuela, with description of six new species.

The species of Lutrochidae occurring in Venezuela are revised. The only previously recorded species, Lutrochus acuminatus Grouvelle, is redescribed and a lectotype is designated. Lutrochus vestitus Sharp, is recorded from Venezuela and French Guiana for the first time.

Hypsilara royi gen. n. and sp. n. (Coleoptera, Elmidae, Larainae) from Southern Venezuela, with a revised key to Larainae of the Western Hemisphere.

Here we describe a new genus, for a new species of riffle beetle, Hypsilara royigen.n. and sp.
