The genus Klausius Moriuti is recorded for the first time in China. Two new species are described, K. angustus sp. nov. and K. latus sp. nov. Images of the adults and the genitalia are provided. The generic characters are emended based on the Chinese specimens. Keys to the known species are given based on both adults and genitalia.

Black fly larvae and pupae were collected from eighteen New Jersey (NJ) counties spanning all five physiographic provinces, and all five watershed management regions. Collections were made year round from small, medium, and large sized streams, and yielded a total of 40 black fly species in five genera. These collections include three new occurrence records for NJ, Simulium vittatum, S. notiale, and S. definitum; and complete NJ collection data for S. anchistinum. New county occurrence records for Prosimulium canutum, P. clandestinum, S. impar, S. parnassum and S. vandalicum are also reported. Collections included four NJ Simulium species limited to the Coastal Plain, and three species restricted to the upper Delaware River in NJ. The most pestiferous group of NJ black flies, the S. jenningsi group, was represented by seven species found in all five physiographic provinces of the state. A region along the eastern glacial terminus which includes northern NJ supports a regional simuliid species diversity that is among the highest in North America.

This paper deals with the identity, geographical distribution and host associations of Dicerataspis species. The authors propose the new synonymy Dicerataspis grenadensis Ashmead, 1896 (= D. flavipes Kieffer, 1909) and redescribe and illustrate D. grenadensis.

Sexual size dimorphism (SSD) is detected in Belostoma elegans for the first time in a multivariate framework. Females are usually bigger than males in Heteroptera species; size is frequently associated with reproductive success. Following this general trend we found that maximum width of the head and interocular distance are biased towards females. Components of body size involved in paternal care and mating behavior did not follow that general rule. Therefore, SSD is not detected in total length without head and maximum width, presumably a consequence of the male egg-laying area which offers a proportional major surface for the clutch. SSD biased to males is found in middle and hind leg segments, used during mating and brooding behavior.

Lepidiella larryi sp. nov., is described and illustrated based on male and female characteristics. Specimens of this new species were captured in Magdalena Province, Colombia, and constitute the first species of this genus recorded in Colombia.

We present the first records of Plumariidae from Paraguay. Specimens of Plumarius hirticornis (André), Plumarius tumidulus Papp and Plumaroides andalgalensis Brothers represent the first records of these two genera and three species for that country. The recently described female of Plumaroides tiphlus is not a plumariid but a bethylid belonging to the cosmopolitan genus Pseudisobrachium Kieffer. The holotype of the only named species based on a female in the family, Plumarius coquimbo Perez D'Angello, has been lost.

The influence of three climatic variables (temperature, air humidity and rainfall) on the incidence of populations of Hg. janthinomys in two geographical regions of Brazil, in the states of Goiás and Tocantins, was studied from February 1996 to December 1997. Rainfall significantly influenced the incidence of the populations of Hg. janthinomys between the months studied (p>0.01). Rainfall was the positive factor determining the biological cycle of the species.

A new Phaenolobus species from Turkey is described and figured. This species is close to Phaenolobus areolator Constantineanu and Constantineanu (1968), and it is distinguished by its smaller body, head roundly narrowed behind, smaller number of flagellomeres, absence of ramulus on discocubital vein, longer subgenital plate and ovipositor sheath, black labrum and coloration of the body. A key for Western Palaearctic Phaenolobus species is given. A check list for Turkish Acaenitinae is added.

Seven species of Trichoptera are recorded from South Carolina for the first time. These species were previously known from North Carolina but have now been found in northern Pickens County, South Carolina, which shares a border with North Carolina. These new records bring the total number of South Carolina Trichoptera species from 253 to 260. Distributions and synonyms for each new record are given.

Three species belonging to the sinensis group of the genus Scythris are treated based on specimens collected in China. Scythris bicruris sp. nov. is described as new, and Scythris dahurica Sinev is newly recorded for this country. Both male and female images of the new species, the illustration of the genital structures and the male sternum VIII of the three species are provided. A key to separate the known species of the sinensis group is included.

The ground-dwelling spider genus Sesieutes Simon, 1897, belonging to the family Liocranidae, is reported from China for the first time, and detailed diagnoses are reviewed. A new species of the genus Sesieutes from Yunnan Province, China, and Chiang Mai Province, Thailand, is diagnosed, described and illustrated under the name of Sesieutes zhui sp. nov.

Biomonitoring of Ohio streams by the Ohio Environmental Protection Agency has found new state records for the Ephemeroptera (mayflies): Baetis brunneicolor McDunnough, Iswaeon anoka (Daggy), Paracloeodes fleeki McCafferty and Lenat, Plauditus cestus (Provonsha and McCafferty), and Rhithrogena manifesta Eaton; the Plecoptera (stoneflies): Pteronarcys cf. biloba Newman; the Trichoptera (caddisflies): Brachycentrus numerosus (Say) and Psiloireta rufa (Hagen); and the Coleoptera (beetles): Gyretes sinuatus LeConte, Dicranopselaphus variegatus Horn, and Microcylloepus pusillus (Le Conte). Additional records are given for the mayfly Paracloeodes minutus (Daggy).

Based on emergence data, Eriotremex formosanus (Matsumura), an exotic horntail established in the southeastern United States, was found to be 1) significantly more abundant in Quercus nigra L. than in Liquidambar styraciflua L. and absent from Pinus taeda L., 2) significantly more abundant in snags than logs, 3) similarly abundant in upland pine-dominated forests and bottomland hardwood-dominated forests, and 4) present at all heights along the bole but not in branches. Captures of E. formosanus in flight intercept traps positioned next to snags, logs and living trees of each tree species support these findings.
