A New Species

A new species of Isoetes, Isoetes acadiensis, from North America is described. The particular combination of characters of microspore and megaspore ornamentation, spore sizes, and chromosome number separates this species well from all existing species. Its range is restricted to the northeastern seaboard of North America and it occurs most commonly in Nova Scotia.

A New Species

Cryptonella? cailliaudi Barrois, 1889, from the Lower Devonian of the Armorican Massif, is tentatively assigned to the athyridid brachiopod genus Planalvus Carter, thus far known only from the Lower Carboniferous of eastern North America. In addition, a new species, Planalvus rufus, is described from the Bois-Roux Formation (Pragian) of Brittany, France. These French species are small brachiopods with complex spiralial and jugal structures, which permit assignment to the order Athyridida.

A New Species

Millipedes of the genus Apheloria Chamberlin, 1921 occur in temperate broadleaf forests throughout eastern North America and west of the Mississippi River in the Ozark and Ouachita Mountains. Chemically defended with toxins made up of cyanide and benzaldehyde, the genus is part of a community of xystodesmid millipedes that compose several Müllerian mimicry rings in the Appalachian Mountains. We describe a model species of these mimicry rings, Apheloria polychroma n. sp., one of the most variable in coloration of all species of Diplopoda with more than six color morphs, each associated with a separate mimicry ring.

AbstractEupontania Zinovjev, 1985, originally described as a subgenus of Pontania, is treated as a distinct genus of the subtribe Euurina Vikberg, which consists of the genera Euura Newman, Eupontania Zinovjev (stat. n.), Pontania A. Costa and Phyllocolpa Benson. Separate keys are given to distinguish these genera and the species-groups of Pontania and Phyllocolpa, and for 11 species of the Pontania crassispinu-group. A new species, Pontania rotundidentata sp. n. is described from eastern North America. The lectotypes are designated for P. crassispina (Thomson) and P. joergenseni Enslin. Pontania devincta MacGillivray (syn. n.) is treated as a synonym of P. populi Marlatt.

A New Species

The ‘clover’ mite, Bryobia praetiosa Koch, has long been known to be a complex of closely related species or biological races differing greatly in host range, life-history, and habits. Morgan and Anderson (1957) reviewed the problem and described the form occurring on fruit trees in British Columbia as a new species, B. arborea, to be known as the brown mite, and these authors (Anderson and Morgan, 1958) also published a detailed study of the life-histories and habits of this species and of the true clover mite, B. praetiosa. Although the presence of Bryobia mites on fruit trees in Eastern North America, including Ontario, has long been recognized, they have seldom received more than casual mention and no extensive study of their biology in this area appears to have been undertaken. The species has little economic importance in Ontario (Putman and Herne, 1959).

A New Species

A new species of Apatemyidae,Sinclairella simplicidens, is based on four isolated teeth that were screenwashed from fissure fillings at the late Oligocene Buda locality, Alachua County, Florida. Compared to its only congenerSinclairella dakotensis, the new species is characterized by upper molars with more simplified crowns, with the near absence of labial shelves and stylar cusps except for a strong parastyle on M1, loss of paracrista and paraconule on M2 (paraconule retained but weak on M1), lack of anterior cingulum on M1–M3, straighter centrocristae, smaller hypocone on M1 and M2, larger hypocone on M3, distal edge of M2 continuous from hypocone to postmetacrista supporting a large posterior basin, and with different tooth proportions in which M2 is the smallest rather than the largest molar in the toothrow. The relatively rare and poorly-known family Apatemyidae has a long temporal range in North America from the late Paleocene (early Tiffanian) to early Oligocene (early Arikareean). The new species from Florida significantly extends this temporal range by roughly 5 Ma to the end of the Paleogene near the Oligocene-Miocene boundary (from early Arikareean, Ar1, to late Arikareean, Ar3), and greatly extends the geographic range of the family into eastern North America some 10° of latitude farther south and 20° of longitude farther east (about 2,200 km farther southeast) than previously known. This late occurrence probably represents a retreat of this subtropically adapted family into the Gulf Coastal Plain subtropical province at the end of the Paleogene and perhaps the end of the apatemyid lineage in North America.
