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.

Larvae of thirty one species of antlions (Neuroptera: Myrmeleontidae) belonging to eleven genera live in the protection of cave mouths or large rock overhangs in Australia. New taxa proposed here include the following three new genera: Australeon, Newleon, Speleon. The following twelve new species are described: Froggattisca kakadu; Froggattisca rennerensis; Newleon fragilis; Speleon cavernicolus; Speleon pilliga; Speleon yallingup; Stenoleon xanthopsis; Xantholeon cavernicolus; Xantholeon kakadu; Xantholeon newi; Xantholeon pallens; Xantholeon pentlandensis. Two cave species are transferred into a new genus becoming new combinations: Australeon illustris (Gerstaecker), Australeon manselli (New and Matsura). The small non-cave species previously placed in Stenoleon Tillyard are transferred to Bandidus Navás, becoming B. gradostriatus (New), B. copleyensis (New), B. grandithecus (New), and B. navasi (New), new combinations. All known species of six genera (Stenoleon Tillyard, Xantholeon Tillyard, Eophanes Banks and three new genera) are known only in cave mouths. Also, species of Heoclisis Navás, Froggattisca Esben Petersen, Glenoleon Banks, Heoclisis Navás and Myrmeleon Linnaeus contain species living in cave mouths. Two main types of caves are found in Australia; those with loose organic material and those with loose inorganic material. The cave habitat is divided into four zones and several subzones. Many species are restricted to one zone or another but species of Stenoleon may overlap zones. Discussions of the species and some of their biological requirements are provided. One new parasite record is given, an undetermined species of Echthrobacella Girault (Hymenoptera: Encyrtidae) reared from the larvae of Speleon yallingup Miller and Stange. Diagnoses or descriptions are given for all of these cave species including distributional data. Keys to the cave mouth inhabiting antlions of Australia (adults and larvae) are provided including a revised key to the Xantholeon Tillyard.

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 genus Gromphas Brullé (Coleoptera: Scarabaeidae) comprises four species, of which G. aeruginosa (Perty) and G. amazonica Bates are known to occur in Peru. This paper presents a revised description of Gromphas as well as illustrated diagnoses and distributional and ecological data on the Peruvian species.

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.

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.

Based on two “uni-ocellate” females, the world’s first introductions of the milliped order Stemmiulida are recorded from Florida, United States (US). One individual was collected in 1976 in Gainesville, Alachua County (Co.)., in northcentral peninsular Florida, and the other was taken in 1991 some 408 km (255 mi) to the south-southeast in Pompano Beach, Broward Co. The absence of further individuals and additional samples suggests that the introductions did not result in viable populations, and stemmiulidans are not presently established in the state; the Gainesville site was reinvestigated in 2012 without finding additional specimens. New records from Mexico include the first from Chiapas, Oaxaca, Tabasco, Yucatan, San Luis Potosí, and Tamaulipas states, with the northernmost ordinal locality now becoming Rancho del Cielo, northwest of Gómez Farias, in the last. A northward range expansion of about 460 km (288 mi) from the previous limit, Xalapa, Veracruz, the site lies a mere 40 km (25 mi) south of the Tropic of Cancer and only some 320 km (200 mi) south of the Rio Grande and the US border at McAllen, Hidalgo Co., Texas. Indigenous Stemmiulida are not expected in the forested Rio Grande Valley of southernmost Texas, but their occurrence in the adjoining Mexican state renders such a discovery more plausible than before.

The known distribution of a rarely collected omethid, Omethes marginatus LeConte (Coleoptera), includes Arkansas, Connecticut, District of Columbia, Indiana, Maryland, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia. Collection and ecological notes on recent collections in Arkansas, Indiana, and Virginia are presented.

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.
