Forty-five new state records for 41 species of bark and ambrosia beetles (Curculionidae: Scolytinae) are given from the following USA states: Alabama, Arkansas, Colorado, Georgia, Kansas, Mississippi, Missouri, North Carolina, Oklahoma, Tennessee, Texas, and Utah. The identification of Hylastes exilis Chapuis and Hylastes tenuis Eichhoff is discussed, and differences between the species are noted and illustrated.

A total of 256 species of 103 genera of ichneumon wasps (Hymenoptera: Ichneumonidae) was collected in Cabañeros National Park (Central Spain), mainly by Malaise and Moericke traps. Fifty-two species and fifteen genera are reported from the Iberian Peninsula for the first time. The genus Macromalon Townes and Townes, hitherto only known from Nearctic and Oriental regions, is reported from the Palaearctic region for the first time. As a result of the study the Iberian fauna of the fifteen Ichneumonidae subfamilies is increased by 10%. Habitat, phenology and collected material for the new records are also provided.

Ctenipocoris schadei (De Carlo, 1940) is recorded from Brazil for the first time, based on a specimen from southwest Paraná. Notes are presented, regarding size, color pattern and morphology of the tarsal claws.

The invasive leafhopper Balclutha rubrostriata (Melichar) was found in abundance in Bexar County, Texas. An arthropod diversity study along highway right-of-way in September and October, 2008 identified B. rubrostriata as the single most abundant species. This is the first peerreviewed published record of this invasive species in the mainland United States. Other records of this species in the U.S. are discussed. Diagnostic characters of the adults are provided and illustrated, and the nymph is described and illustrated for the first time. Genomic DNA was extracted from one adult and one nymph specimen, and the mitochondrial COI gene was sequenced for each and yielded identical sequences, thus confirming the association of the nymph and adult. Sequences are deposited in GenBank for future use in diagnostic or other studies.

Multichotomous identification keys are provided to the black fly larvae and pupae of New Jersey and neighboring states. Control of black flies is targeted at the aquatic immature stages, making proper identification of larvae and pupae vital for suppression purposes. The key includes 40 species known from NJ and an additional 24 species from surrounding states. A species confirmation table is also included to increase identification accuracy. Diagnostic images of simuliid pupae and larvae are also provided.

Based on recent collections, the checklist of the stoneflies of West Virginia is updated to include 140 species. Four state records, 154 county records and 16 drainage basin records are added to the plecopteran fauna of the state. Range extensions are noted for Perlesta lagoi Stark, P. shubata Stark, P. puttmanni Kondratieff and Kirchner and Neoperla robisoni Poulton and Stewart. Distributions of the new records in seven major drainage basins of West Virginia are presented.

A new Rhopalopsole species belonging to the vietnamica Group, R. yajunae, is described from China. Its relationships with congeners are discussed.

Two new species of the genus Penthetria Meigen from Yunnan are described: Penthetria medialis sp. nov. and Penthetria zhongdianensis sp. nov. A key to the species of the genus from Yunnan, China, is presented for the first time.

Since palatable butterflies are more dependent on evasive flight to escape from predators, they should be more restricted in their flight-related morphology than unpalatable ones. We compared: the ratios between the (1) length of head plus thorax and the length of abdomen (A/B), (2) length of the tip of the head to wing base and the length of the wing base to end of the abdomen (C/D), (3) the variances of A/B and C/D, (4) the proportion between the thoracic and the body weight, and (5) the flight speed between palatable and unpalatable butterflies. A/B and thoracic/body weight were higher for palatable species, indicating higher body symmetry and muscular mass. However, flight speed did not differ. Unexpectedly, the variance of A/B was higher for palatable species while that of C/D did not differ. Therefore, corporal allometric measurements of Neotropical butterflies are good predictors of palatability, though not of flight speed.

The genus Ressia Sinev is recorded for the first time in China. Ressia auriculata sp. nov. is described, and Ressia quercidentella Sinev, 1988 is newly recorded for the Chinese fauna. Images of both adults and genitalia of the two species are provided.

The two species of Stylolidia that are found in Thailand are discussed, including one new species S. khaoensis. A key to the three known species of the genus is also included.

The syntypes of Siphonophora fragariae var. Immaculata Riley were rediscovered in the aphid collection of the United States of America National Museum of Natural History. The name (S. fragariae Immaculata) previously being largely lost and forgotten, we here establish it as the senior synonym of Macrosiphum euphorbiae (Thomas). Reversal of precedence can be validated, however, and we establish S. fragariae Immaculata as a nomen oblitum and M. euphorbiae a nomen protectum with respect to each other. In uncovering the original description of the Riley species, we also found a description of Aphis rapae var. laevigata Riley. We have not found A. rapae laevigata anywhere else in the literature nor have we found any type specimens. Based on Riley's succinct description and host plant identity, we consider it a nomen dubium synonym of Myzus persicae (Sulzer). Because the short articles publishing the two aphid names have been missing from taxonomists' libraries, they are transcribed in their entirety.

Belonuchus godmani is redescribed based on the revision of 87 specimens, including the type specimens, from México, Guatemala, Costa Rica and Panamá. It is recorded for the first time from Costa Rica, as well as from Department of San Marcos, Guatemala, and the state of Querétaro, Mexico. Lectotype and paralectotypes are designated for this species. Distributional patterns and biology are reported.
