Chromosomes of four rare and localized Caribbean Prioninae (Coleoptera: Cerambycidae) species were analysed. All have 26, XY karyotypes. Those of Solenoptera canaliculata (Solenopterini) from Guadeloupe nearby islands Les Saintes and Marie-Galante and S. quadrilineata from Martinique look similar. They have a single pair of sub-metacentric autosomes. The karyotype of S. touroulti from St. Lucia has three sub-metacentric pairs. It appears closer to that of Hovorodon maxillosum (Mallodontini) from Marie-Galante which has ten sub-metacentric pairs. The CO1 gene sequence, taking two European species Aegosoma scabricorne (Prioninae: Aegosomatini) and Ergates faber (Prioninae: Ergatini) as external groups was analysed in S. canaliculata and S. quadrilineata. In spite of their karyotype similarity, their CO1 genes differ by a strong accumulation of mutations. Thus, either chromosomal or genetic data confirm the species status of the three closely related Solenoptera species. Ten different CO1 haplotypes are found among the 21 specimens of S. canaliculata studied from les Saintes and Marie-Galante. Both different haplotypes were found in each island and identical haplotypes were found in different islands. Hence, the gene flow was not interrupted. Biogeographical parameters favor the hypothesis that repeated passages between islands were made possible by floating trunks, principally from Les Saintes to Marie-Galante.

We present new southeastern United States distributional records for Stictoleptura canadensis (Olivier, 1795), Leptura subhamata Randall, 1838 (Coleoptera: Cerambycidae: Lepturinae), and Heterosternuta cocheconis (Fall, 1917) (Coleoptera: Dytiscidae: Hydroporinae) which extend the southernmost limits of the known distributions for these species. We present new state records for these species.

Thirty five Western Hemisphere species of Glaresidae (Coleoptera) are recognized. Descriptions of new species, redescriptions of those previously described, keys to groups and species, and illustrations of pertinent morphological characters are presented. Nineteen newly described species are Glaresis australis, G. bajaensis, G. bautista, G. caenulenta, G. california, G. costaricensis, G. costata, G. falli, G. dentata, G. donaldi, G. imitator, G. limbata, G. montenegro, G. paramendica, G. sabulosa, G. tumida, G. warneri, G. yanegai, and G. zacateca. Glaresis cartwrighti Gordon is recognized as a junior synonym of G. inducta Horn.

A revision of the genus Acentroptera Guérin-Méneville, 1844 (Coleoptera: Chrysomelidae: Cassidinae)
(2014)
The species of the genus Acentroptera Guérin-Méneville, 1844 are revised. Thirteen species are treated as valid and are illustrated. A neotype is designated for A. tessellata Baly. Acentroptera maculata Pic from Brazil and A. rubronotata Pic from Brazil are treated as incertae sedis. Acentroptera bita n. sp. and A. lineata n. sp. both from Panama are described as new. A key to the 13 treated species is presented. Five species appear to be associated with bromeliads (Bromeliaceae).

Four species of mole crickets (Orthoptera: Gryllotalpidae) are known from the West Indies: Neocurtilla hexadactyla (Perty), Scapteriscus abbreviatus Scudder, S. didactylus (Latreille), and S. imitatus Nickle and Castner. All are adventive (not native). We document their distributions in West Indian islands/countries by use of records from the literature and examination of specimens. Scapteriscus abbreviatus has been suggested to have arrived in, and been transported about the West Indies in ship ballast (immigration). Based on records of arrival in various parts of the West Indies and the species’ inability to fly, this suggestion seems reasonable. Scapteriscus imitatus pparently was released in Puerto Rico as a result of mistaken identification (introduction – arriving with assistance from humans – although inadvertent), and has not expanded its range in the West Indies. Although the principal mode of dispersal for the other two species also has been suggested to be ship ballast, we present an alternative based on flight which would seem at least equally as plausible. We suggest that S. didactylus could have dispersed by flight from South America through the Lesser Antilles; likewise N. hexadactyla probably from the Yucatan Peninsula to Cuba, and from South America northward through the Lesser Antilles, in at least some localities assisted by wind. Our zoogeographical alternative, if correct, means that the natural range expansions of these latter two species began very long ago and without human assistance – they were not introduced recently to the West Indies.

Cupido comyntas (Godart), the eastern tailed-blue, is a legume-feeding caterpillar native to North America. One of its three subspecies, Cupido comyntas comyntas (Godart), is distributed over the eastern half of the United States and southeastern Canada. This subspecies was recorded for the first time feeding on cultivated soybean. Caterpillars fed upon soybean at various developmental stages, ranging from seedlings to podded plants, in several fields within a 5-km radius in Brookings County, South Dakota, from July 1 – 25, 2013. Feeding was confined to leaves, and no pod damage was observed. The caterpillars occurred at relatively low densities that were unlikely to have affected yield of soybean crops. An early maturity soybean line, H007Y12, had a lower incidence of C. comyntas comyntas caterpillars than a relatively later maturity line, H19Y11. Butterflies of C. comyntas comyntas were observed feeding from soybean flowers on multiple dates in July and early August. As the geographic distribution of C. comyntas comyntas considerably overlaps the area where soybean is grown, entomologists should watch for and document any additional infestation of soybean by these caterpillars.

A new species of the genus Onychopygia Beier, 1962 Orthoptera: Tettigoniidae: Pseudophyllinae) from the northern slopes of Los Cuchumatanes Mountains, Huehuetenango, Guatemala is described and illustrated. The morphological differences and peculiarities between O. panamensis Beier, 1962 and O. brachyptera n. sp. are discussed. The finding of this new taxon extends considerably into entral America our previous knowledge on the distribution of the Eucocconotini tribe. Finally we provide a revised taxonomic key to the Eucocconotini tribe.

New Species of Phyllophaga Harris (Coleoptera: Scarabaeidae: Melolonthinae) from northeastern Mexico
(2014)
Three new species of Phyllophaga are described from northeastern Mexico: P. (s.str.) gramma n. sp. from grasslands near Monterrey city, state of Nuevo Leon; P. (s.str.) jeanmathieui n. sp. from mixed forests of Sierra Chipinque, Nuevo Leon; and P. (Listrochelus) pinophilus n. sp. from pine-oak forests of mountains in Nuevo Leon and Coahuila. Illustrations of diagnostic structures and comments about the relations of each species are provided.

The external morphology of the thorax and abdomen of four species of Neotropical Hesperiidae, belonging to different tribes, are described and illustrated. The morphological characters traditionally used in the classification of the family are reviewed and new information is added with emphasis on the characters usually neglected in the classification and identification of Hesperiidae and Lepidoptera. The use of these characters, along with those commonly used in literature for the identification and taxonomy of the family, is discussed, aiming to contribute to comparative studies of morphology and taxonomy of this group.

Five species of the aphid genus Sipha Passerini (Hemiptera: Aphididae) are reported in North America and are reviewed herein. Of these species, three are adventive species and include: Sipha elegans del Guercio, Sipha glyceriae (Kaltenbach), and Sipha maydis Passerini. Sipha maydis was discovered in California in 2007 and now has been found in Georgia. The genus also includes two native species: Sipha agropyronensis (Gillette) and Sipha flava (Forbes). Sipha maydis can be distinguished easily from all the other species in the genus that occur in North America because it is black. All the species except S. agropyronensis have been implicated in damage to crop plants. A key to the apterae and alatae of Sipha found in North America is included.
