In North America, Paleogene Verrucidae are rarely encountered. Only a single named species has been previously discussed by Zullo & Baum (1979), who provisionally assigned a Palaeocene form from North Carolina to Verruca rocana Steinmann, 1921. Eocene deposits in Washington State (USA) have now yielded two new species from intertidal to shallow water environments: Verruca gailgoedertae sp. nov. from the middle Eocene Crescent/McIntosh transition zone, and Verruca sorrellae sp. nov. from the upper Eocene to lowest Oligocene Gries Ranch and basal Lincoln Creek formations. Both species are characterized by punctate shell plates, and are placed in the lineage of Verruca stroemia (O.F. Müller, 1776). In Alabama, marls from the upper Yazoo Formation (Pachuta and Shubuta Members) have yielded Verruca alabamensis sp. nov., an uncommon deeper water form associated with abundant brachiopods and phosphate deposition. This last species shows no development of punctae and is not related to the lineage that leads directly to Verruca stroemia.

The milliped genus Amplaria Chamberlin 1941 was synonymized with Striaria Bollman 1888 by Hoffman (1980). Examination of a much wider range of materials of nominal Striaria species both from eastern North America and the Pacific coastal states shows that some species occurring from California to Washington (state) represent a distinct phyletic line, for which Amplaria Chamberlin 1941 is the oldest available generic name. Speostriaria Causey 1960 is a synonym of Amplaria. Amplaria muiri n. sp. and A. adamsi n. sp. are two new, recently discovered species from caves in Sequoia and Kings Canyon National Parks, California. Illustrations are provided of a specimen that may represent the type species, Amplaria eutypa (Chamberlin) 1953.

Nine species of fossil isopods have been studied from Cretaceous to Pleistocene rocks of North America. This represents all known species from the Mesozoic and Cenozoic fossil record on this continent. Four species of Palaega were studied. Palaega goedertorum Wieder and Feldmann, 1989, from upper Eocene to lower Miocene rocks of Washington state, has served recently as the basis for restructuring the genus. Emendations are made to species descriptions of Palaega guadalupensis and P. williamsonensis from the Cretaceous rocks of Texas. The fourth species of Palaega, P. lamnae, also from the Cretaceous rocks of Texas, although of doubtful affinities with this genus, was not removed due to lack of sufficient information to reassign it. Two new species are described, Cirolana enigma, from Lower Cretaceous rocks of South Dakota, and Archaeoniscus texanus, from the Cretaceous of Texas. This is the first report of Cirolana from the fossil record. Two sphaeromatid isopods were included: one, Sphaeroma burkartii from Tertiary rocks of Mexico, was not located for study; the other, Eocopea oculata, is from Miocene rocks of southern California. Two specimens of the valviferan genus Saduria, from Pleistocene deposits in Canada, were also studied.

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.

Introductory materials for a revision of the milliped family Trichopetalidae are presented, and the species of three of the five genera are described (Nannopetalum n. gen., Trigenotyla Causey, 1951, Causeyella, n. gen.). Nannopetalum is related to Trichopetalum, and includes three new species from the Appalachian piedmont: N. pattersonorum (Virginia), N. vespertilio (North Carolina), and N. fontis (Alabama). Trigenotyla Causey includes four species: T. parca Causey (Arkansas), T. vaga Causey (Oklahoma), T. blacki n. sp. (Oklahoma), and T. seminole n. sp. (Oklahoma). Causeyella n. gen. is based on Scoterpes dendropus Loomis (Missouri and Arkansas), and also contains two new species: C. causeyae n. sp. (Arkansas) and C. youngsteatorum n. sp. (Arkansas). Causeyella and Trigenotyla are closely related.

Two new species are here described as segregates from Heteranthera multiflora. Heteranthera missouriensis sp. nov. has 5–13 flowers on an elongate floral axis, lavender to purplish flowers, a smaller perianth with the tube 3–5 mm long and lobes 3–4.5 mm long; it is common in the southern Great Plains of North America. Heteranthera pauciflora sp. nov. has 3–6 flowers on a shortened floral axis, commonly enclosed by the subtending spathe, white to light lavender flowers with the tube 8–10 mm long; it is known from the Atlantic coast from New Jersey to North Carolina. A taxonomic key to all species of the genus in North America, and a modified description of Heteranthera multiflora, are provided.

Three new species of rhagidiid mites, Rhagidia breviseta, n.sp., R. parvilobata n.sp., and R. distisolenidiata n.sp., from the Nearctic region are described. Their interspecific relationships are discussed and two new species-groups, gigas and quadrisolenidiata, are defined.

The genus Botanophila Lioy has several species distributed in North America, but none had been recorded from Mexico. Here we describe three new species of Botanophila from the highlands of the Mexican Transition Zone. We include images of habitus, drawings of the terminalia and a key to facilitate the identification of species. Remarkably, the male of the new species has dichoptic eyes, an unusual characteristic in Anthomyiidae.

AbstractThree new species of Oxyporus are described from North America, O. ashei from North Carolina; O. kiteleyi from Québec, Massachusetts, and Georgia; and O. neomexicanus from New Mexico. All species are illustrated and a key is presented for the determination of all the species of the genus from America, north of Mexico.
