Three new genera and three new species of fossil ‘osmylid-like’ Neuroptera or ‘cf. Osmylidae’ are described: Saucrosmylus sambneurus n. gen. and n. sp., Laccosmylus calophlebius n. gen. and n. sp. and Rudiosmylus ningchengensis n. gen. and n. sp., all of them from the Jiulongshan Formation, Middle Jurassic, situated at Ningcheng county, Inner Mongolia, China. The only family to which our fossil lacewings may provisionally be assigned is the Osmylidae. The new fossil genera and species do not reasonably fit in any of the previously known subfamilies within Osmylidae and a new subfamily, Saucrosmylinae, is proposed. Its remarkable features are the large body size, the R1 area with many cross-veins producing 2 or more rows of cells, the curved Rs bent anteriorly distally, nygmata present and the CuA bounding a large triangular area.

A new genus of Mesoveliidae, Seychellovelia, with a single included species, S. hygrobia n. sp., is described from the islands of Silhouette and Mahe in the granitic Seychelles. This new taxon is compared to other mesoveliid genera, and its key morphological characters illustrated. Information is also provided on the habitat preferences of S. hygrobia, and an updated distributional map of mesoveliid genera on a world basis is provided, accompanied by a discussion of zoogeographical implications.

Savius terrabanus, new species (Costa Rica), Scamurius goianus, new species (Brazil) and Scamurius pucalpanensis, new species (Peru) are described and placed in the coreid tribe Discogastrini. Details of antennae, pronotum, male genital capsule and parameres are illustrated. New localities are given for Savius diversicornis.

The Veliinae of Vietnam are reviewed, and the new species Velia tonkina described from the Huong Lien Son mountains in the far north of the country. Three additional species of Veliinae, Chenevelia stridulans, Angilia bispinosa, and Angilia orientalis, are recorded from Vietnam for the first time. Distribution maps are provided for all these species, dorsal habitus illustrations are provided for Velia tonkina and Chenevelia stridulans, and illustrations of male genitalic structures are provided for Velia tonkina.

A new species, Cholula bracteicola, associated with Ficus cotinifolia is described from Veracruz, Mexico. All immature stages are described and illustrated and its biology is presented. This arboreal species of Cholula lives around the basal bracts of the fruit and feeds on the seeds by using its long labium to penetrate the wall of the fruit.

Our studies of the Ephemeroptera family Ephemerellidae have revealed new synonyms and a new combination for species that have been placed in the genus Crinitella Allen and Edmunds. The type species, Crinitella coheri (Allen and Edmunds), is variable in color, and the shape of the left mandible is the same as that of C. permkami Wang and Sites, indicating that C. coheri (Allen and Edmunds) 1963 = C. permkami Wang and Sites, 1999, new synonymy. Drunella nasiri (Ali), new combination, was included in Crinitella previously. All other species previously included in Crinitella are synonyms of species in different genera, as follows: Cincticostella levanidovae (Tshernova) 1952 = Crinitella swatensis (Ali) 1971, new synonymy, and Torleya nepalica (Allen and Edmunds) 1963 = Crinitella wahensis (Ali) 1971, new synonymy.

Crepidodera bella Parry (Coleoptera: Chrysomelidae: Alticini), previously known only from Florida, South Carolina, Alabama, and Louisiana, is discovered in central Maryland. This species is sympatric with C. browni Parry on Salix nigra growing along swamps in the McKee-Besher Wildlife Management Area (39°04′30″N, 77°23′00″W). Morphological features of the integument and genitalia are described and compared to C. browni.

An isolated population of Moneilema appressum LeConte was discovered above Long Park in the Chiricahua Mountains of southeastern Arizona (31°52′44″N, 109°17′12″W) during July 2001. Specimens of this flightless lamiine cerambycid were observed hiding and walking in the junctures of Echinocereus coccineus Engelmann (Cactaceae) at 2,760 m (9,055 feet). These data represent new host plant and elevation records for this species.
