Based on a study of the characters used to define it, the genus Euphoriopsis Casey is placed in synonymy with Euphoria Burmeister. Euphoria punicea Janson is placed in synonymy with Euphoria steinheili Janson. Morphological characters supporting the synonymies, and the species' distributions and biological data are reviewed.

A new species of Culcua Walker (Diptera: Stratiomyidae), C. lingafelteri Woodley, new species, is described from northern Vietnam. It is diagnosed relative to other species using the recent revision of the genus by Rozkošný and Kozánek (2007). This is the first species of Culcua reported from Vietnam.

The tribe Krisnini (Hemiptera: Cicadellidae) is presently known in the New World from three species from Puerto Rico and one species from Dominican Amber, all described in the Old World genus Krisna Baker. The three species from Puerto Rico are being placed in Lipokrisna, new genus, with Krisna insularis Oman as the type species, becoming Lipokrisna insularis (Oman), new combination. The other species in this genus are L. montana (Caldwell) and L. aesta (DeLong) both new combinations. The one species from Dominican amber is placed in the Genus Archiokrisna, new genus, with Krisna garciamarquezi Dietrich as the type species, becoming Archiokrisna garciamarquezi (Dietrich), new combination. The genus, Neokrisna, new genus, is described for six new species from the Dominican Republic, with Neokrisna oncora, new species, as the type species. The other new species in the genus are N. breva, N. decliva, N. libera, N. longula, and N. stena. A key to the species of Neokrisna is included. The three genera are compared with each other and the old World genus Krisna.

The genus Haroldiataenius Chalumeau, 1981 (Aphodiinae: Eupariini) from southern United States, Mexico, and Central America is revised and nine species are recognized. The subgeneric name Sayloria Chalumeau, 1981 is synonymized with Haroldiataenius (sensu stricto) and Ataenius sabinoi Cartwright, 1974 is synonymized with A. lucanus Horn, 1871. Five species are transferred to Haroldiataenius from the genus Ataenius Harold creating the following new combinations: H. convexus (Robinson), H. griffini (Cartwright), H. lucanus (Horn), H. saramari (Cartwright), and H. semipilosus (Van Dyke). One new species,Haroldiataenius buvexus is described from Texas, USA. A key to species of Haroldiataenius is included and pertinent morphological details are illustrated.

Surveys during the summer of 2004 and August 2009 on Prince of Wales Island, Alaska, USA resulted in collection of 1064 adult spiders representing 84 species. Barcoding of spiders collected in 2009 resulted in DNA barcode data for 212 specimens representing 63 species. DNA barcode data were then used to facilitate the identification of otherwise unidentifiable juvenile and female specimens as well as to investigate phylogenetically four lineages with large branch lengths between specimens. Using morphological and DNA barcode identifications provided a more complete list of identified specimens than was possible using morphological data alone.

We provide an illustrated list of species belonging to the genus Symmachia Hübner, [1819] (Lepidoptera: Riodinidae: Symmachiini) collected during an expedition conducted between September 10-21, 2011 in the northern part of the Parque Nacional da Serra do Divisor, Acre, Brazil, a remote region of Amazon rainforest. A total of 46 individuals were collected belonging to 15 species. For all recorded species, drawings of male genitalia and behavioral information are provided to support future studies on the taxonomy of the group. A new species, Symmachia divisora Dolibaina and Leite, sp. nov., is described, and a revised status for Symmachia hetaerina hesione Stichel, 1910, stat. rev., is proposed.

The species of the "modestus" group of the genus Psalidognathus Gray (Cerambycidae: Prioninae) (currently with four species and three subspecies), which are recognized mainly by the antennomeres without apical spines, are studied. Psalidognathus thomsoni Lameere, 1885 is revalidated as a species distinct from P. modestus Fries, 1833. Psalidognathus erythrocerus reichei Quentin and Villiers, 1983 and P. erythrocerus pubescens Quentin and Villiers, 1983 are considered as different species from P. erythrocerus Reiche, 1840. Psalidognathus colombianus Demelt, 1989 and Psalidognathus modestus chocoensis Salazar, 2005 are synonymized with P. modestus, syn. nov. Psalidognathus rufescens, although belonging to “friendii” group, is redescribed and some remarks are added. Species redescribed: P. erythrocerus; P. modestus; P. reichei; P. rufescens; P. onorei Quentin and Villiers, 1983; and P. thomsoni. Psalidognathus cerberus sp. nov. is described from Colombia and Ecuador. A provisional key is provided to males of species of "modestus" group.
