Nearctic Stichopogon species with white-banded abdomens are reviewed. Stichopogon venturiensis, new species, is described from the Pacific coast in Santa Barbara, Ventura, and Los Angeles counties, California. A lectotype is designated for Stichopogon trifasciatus (Say), and Stichopogon salinus (Melander) from the eastern margin of the Great Basin is synonymized with S. trifasciatus (new synonymy). An identification key to the three Nearctic species of Stichopogon with white-banded abdomens is presented.

During 2003–2006, a general aphid survey was conducted in the Great Smoky Mountains National Park in the American states of Tennessee and North Carolina. The project was undertaken within the context of the All Taxa Biodiversity Inventory and funded by Discover Life in America. In all, 121 aphid species were documented. When present, attendant ants were also collected and identified, as were the aphid host plants. The aphids, their attendant ants, and host plants are listed here. In addition, a checklist of the plants of the park and a catalog of the aphids of North America were cross-referenced to create a list of aphids not actually found but likely present in the Great Smoky Mountains National Park, increasing the number to 206. Finally, we used Chao1 statistical techniques to estimate the total number of aphid species based on our sampling to date. These produced estimates of 201–214 species.

During a study of Lecithoceridae of Papua New Guinea, an undescribed species of Torodrora, Torodrora wauensis Park, new species, was discovered. The new species is described, and illustrations of the adult, labial palpus, hind tibia, wing venation, and male and female genitalia are provided. The new species is compared with Torodrora meyi Park from the Philippine Islands, to which it is closely allied.

Five new species of Acordulecera Say are described from the southwestern United States: Acordulecera sonoita, A. grisselli, and A. whittelli from southern Arizona, and A. algodones and A. kimseyi from southern California. These are the first records for the family Pergidae from Arizona and California. A key is given for the currently recognized North American and Mexican species.

Eriotremex magnificus, n. sp., from Malaysia is described and illustrated. Current information, including some new distributional records, is given for the other 12 species currently placed in the genus, and a revised key to species is provided.

Pseudodineura kasatochi Smith, n. sp., is described from Kasatochi Island, Alaska. This is the first record of a species of Pseudodineura from Alaska. The specimen was collected prior to a volcanic eruption in August 2008 that nearly destroyed all life on the island. It is separated from other Palearctic and Nearctic species of the genus.

Monoctenus sanchezi Smith, n. sp., is described. It was found damaging Juniperus flaccida Schlechtendal (Cupressaceae) in San Luis Potosí, Mexico. This is the second Mexican species of the genus. A review of Monoctenus from southwestern United States, Mexico, and Central America is presented, with M. sadadus Smith a new country record for the United States and new records of the genus for Utah and as far south as Guatemala.

Type specimens or the type series of 27 North American Herpetogramma species names were located, mostly in European museums, verified, and dissected. Acharana descripta (Warren) is designated as a new synonym of Herpetogramma phaeopteralis (Guenée). Fifteen lectotypes and 14 paralectotypes are designated where it was deemed necessary to fix and stabilize the current concept of the name. A checklist and a key to nine North American species are provided with photographs of the adults.

The recently established genus Rajburicoris Carpintero and Dellapé, 2008 is recorded from India for the first time based on a new species, R. keralanus Yamada, collected from Kerala State. This new species feeds on Liothrips karnyi, which infests black pepper leaves and forms leaf-curl galls. It differs from R. stysi Carpintero and Dellapé, 2008 by the labium reaching middle of mesosternum, the ostiolar peritreme weakly curving anteriorly before strongly recurving posteriorly at apex, and the omphalus basally widened and gradually more slender apicad. Biological information of the new species is provided. The genus is redefined based on the following autapomorphies: 1) pygophore with an irregular, small parameroid along left edge; 2) paramere strongly curved, very long, basally widened, and gradually narrowed toward apex; and 3) omphalus extremely long and circularly curved.
