AbstractThree new species of ascid mites are described and illustrated: Proctolaelaps subcorticalis, Lasioseius corticeus, and Gamasellodes rectiventris. All are subcortical associates of bark beetles in North America.

AbstractSix species of Proctolaelaps, found associated with insect pests of pine forests in the southeastern United States, are described and illustrated. These are: P. bickleyi (Bram), P. fiseri Samšinák, P. hystrix (Vitzthum), and three new species, P. dendroctoni, P. dioryctriae, and P. hystricoides. Newly recorded for North America are P. fiseri, P. hystrix, and P. ulmi Hirschmann; distributions for the last two species include British Columbia. Garmania striata Westerboer is synonymized under P. bickleyi; the problem of the lewisi species complex, which includes P. bickleyi, P. lewisi (Garman and McGregor), and P. utahensis (Chant), is noted.Although the food habits of these and related mites are mostly unstudied, tentative observations indicate that some species are commensals and others are predators of their insect associates. Investigation of such mites and their relationships with forest pests is urged.

The amphipod genus Orchestia is revised. It now includes 10 species of which three are new: O. forchuensis sp. nov. from north-eastern North America and Iceland., O. perezi sp. nov. from Chile and O. tabladoi sp. nov. from Argentina. Orchestia inaequalipes (K.H. Barnard 1951) is reinstated. The type species of the genus, O. gammarellus is redescribed based on material from Fountainstown, Ireland and a neotype is established to stabilize the species. The species was originally described from a garden in Leiden, far from the sea. Its true identity is unknown and no type material exists. Orchestia gammarellus (Pallas, 1776) is shown to be a sibling species group with members in both hemispheres of the temperate Atlantic as well along the Pacific coast of South America. A hypothesis for the establishment of the current distribution of Orchestia species is presented that extends back to the Cretaceous.

Three new species of Lumbriculidae from southeastern North America are attributed to Eclipidrilus Eisen. All are small worms (diameter 0.2–0.5 mm), having semi-prosoporous male ducts with the atria in X, and spermathecae in IX. Eclipidrilus breviatriatus n. sp. and E. microthecus n. sp. have crosshatched atrial musculature, similar to some E. (Eclipidrilus) species, but they differ from congeners in having small, compact spermathecal ampullae. Eclipidrilus macphersonae n. sp. has a single, median atrium and spermatheca. The new species have been collected only in Sandhills and Middle Atlantic Coastal Plain streams of North Carolina.

Twelve North American species of the section Cordatae of the genus Salix (willows) were studied to clarify their taxonomy. The sections Adenophyllae (Commutatae) and Wolfianae are included here in section Cordatae. Characteristics of the epidermal cells and pollen grains were of no taxonomic value. Chromosome counts were obtained for 6 of the 12 species. One other species had been counted earlier. There are three diploid species, two tetraploids, and a hexaploid. One other species (?) has both diploid and tetraploid populations. Flavonoid chemistry of the leaves was the most important and constant characteristic. Each species has a consistent combination of compounds different from those of all other species of the section. Cytology, chemistry, morphology, and distribution were well correlated. Keys to pistillate material, synonymy, descriptions, distribution maps, and representative specimens are included. Three new species are described and one varietal transfer is made.

AbstractThe taxonomy and biology of New World species of Chrysolampinae are reviewed with diagnoses given for the subfamily, genera, and species. A key to the species of Chrysolampus and a summary of geographic distribution and information on host and floral associations are presented. Three new species are described from North America (Chrysolampus improcerus, C. luridus and C. elegans); Chrysolampus lycti Crawford is transferred to Perilampus and synonymized with the European species P. micans Dalman. The genus Chrysomalla is recorded in the New World for the first time based on the new species Chrysomalla hesperis. An explanation of the historical biogeography of the genera is proposed that is consistent with Late Cretaceous and Tertiary geological, botanical, and climatic information. It is suggested that the extant species are descendents of elements of a widely distributed arid biota.
