Amorbia erinae, new species, is described and illustrated from the states of Durango and Chihuahua, Mexico. Superficially, the new species is highly divergent from its congeners, with a forewing pattern that features longitudinal bands of pale orange and cream, typical of tortricids that either feed on pine or occur in pine-dominated montane habitats, e.g., Eupinivora ponderosae Brown (Euliini: Cochylina), Argyrotaenia coconinana Brown & Cramer (Archipini), and Sparganothis bistriata Kearfott (Sparganothini). However, the absence of ocelli and features of the male and female genitalia convincingly place the new species in Amorbia.

Dasineura abietiperda (Henschel), a European pest of Norway spruce, Picea abies (Pinaceae), is reported as new to northeastern North America where the tree is widely planted and valued as an ornamental. Adult gall midges emerge in early spring, mate and deposit eggs on twigs or new shoots. The larvae burrow into tissue causing swellings to form under bud scales and less frequently along shoots or near the terminal bud. Larvae overwinter in the galls. Field symptoms include bent twigs or shoots, swellings in nodes and needle drop. A new genus, Piceacecis Gagné is described to include D. abietiperda and its North American relative, Phytophaga tsugae (Felt), which occurs on native American white spruce, Picea glauca. Both cecidomyiids are redescribed with illustrations. The names of both are new combinations in Piceacecis, and Phytophaga piceae Felt is a new junior synonym of Piceacecis tsugae. In the past these synonyms have been combined also with Mayetiola.

Crambidia xanthocorpa, new species, is described and illustrated from the eastern United States. Morphological characters, especially those of the genitalia, and geographic distribution distinguish the new species from its most similar North American congeners.

A new species of Pison from Australia is described and illustrated. Comparisons with related species are given.

The two North American species of Hyperimerus Girault are reviewed. Hyperimerus corvus Girault is redescribed from a newly designated lectotype, and the male is described for the first time. H. pusillus (Walker) is also redescribed briefly and new locality records provided to document range extension. Notes on extra-limital specimens of Hyperimerus from Guatemala, Japan, South Korea, Thailand are also provided.

Ophiomyia kwansonis Sasakawa, the daylily leafminer (DLM), previously known only from Japan and Taiwan, and present but unidentified in the continental United States since at least 2008, is here documented from detections made in 2011. Known distribution, including U.S. and European records, is given, with a number of new state records documented by photographic images of the characteristic, unique larval feeding damage found in Hemerocallis spp. Some biological observations are also included.

Two new species of Brachyodina Lindner from the Caribbean are described, B. janestanleyae Woodley, new species, from the Dominican Republic and B. caymanensis Woodley, new species from Grand Cayman Island. A key to the species known from the Caribbean islands is provided.
