Ostertagia trifurcata was found in a steer in Canada and now recorded for the first time as infecting cattle in North America. Adult female worms showed marked variation in the vulvar region and were shorter than previously recorded for the species in sheep. There was no history of the host either grazing or being housed in areas or adjoining areas previously used by sheep.

SummaryThe Devonian brachiopod Tropidoleptus is recognized for the first time in South Africa. It is present in the lower part of the Witteberg Group at four widely separated localities. Data regarding the stratigraphical range of the genus elsewhere, combined with information on recently described fossil plants and vertebrates from underlying strata of the upper Bokkeveld Group, suggest that a Frasnian or even Givetian age is reasonable for the lower part of the Witteberg Group. The recognition of Tropidoleptus in a shallow water, near-shore, molluscan association, at the top of the South African marine Devonian sequence, is similar to its occurrence in Bolivia, and suggests a common Malvinokaffric Realm history of shallowing, prior to later Devonian or early Carboniferous non-marine sedimentation. It is noteworthy that Tropidoleptus is now known to occur in ecologically suitable environments around the Atlantic, but is absent from these same environments in Asia and Australia. Tropidoleptus is an excellent example of dispersal in geological time — first appearing in northern Europe and Nova Scotia, then elsewhere in eastern North America and North Africa, followed by South America and South Africa, while continuing in North America.

The European, or Essex skipper, Thymelicus (= Adopaea) lineola (Ochs.), was accidentally introduced into North America at London, Ontario, sometime before 1910 (Saunders, 1916). The history of its subsequent spread through southern Ontario and adjoining parts of Michigan and Ohio was reviewed by Pengelly (1961), who received the first report of extensive damage to hay and pasture crops by this insect in Ontario from the Markdale area of Grey County in 1956. A survey in 1958 (Pengelly, 1961) showed that the skipper “appeared to be present throughout the southern part of the province except for the Bruce peninsula and possibly the Windsor area. The northeasterly boundary appeared to he along a line from Midland, south around the west side of Lake Simcoe, east to Lindsay and south to Whitby.” The present author collected T. lineola larvae from the Belleville area for the first time in 1959.

AbstractThe Microgastrinae wasp Diolcogaster claritibia (Papp, 1959) (Hymenoptera: Braconidae), a parasitoid of the diamondback moth, Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae), is recorded from the Nearctic region (Alberta, Manitoba, and Ontario, Canada) for the first time. In spite of some minor morphological and molecular (DNA barcoding) differences, the available data indicate that the European and New World specimens should be considered one species, but more specimens and loci need to be sampled to conclusively determine the phylogeographic history of the species. Diolcogaster claritibia seems to be widely distributed within the Holarctic, and the molecular data suggest that it was recently introduced to North America from Europe.

A parasitic nematode, Howardula aptini (Sharga 1932) Wachek, 1955, is reported for the first time in North America, and is a parasite of two serious blueberry thrips. Parasitized thrips probably do not produce eggs as the ovarial tissue is greatly reduced by the nematode and dissections failed to reveal eggs in infected individuals. Parasitism varied and was 71% in one sample. Introduction of the nematode into unparasitized populations is feasible. Previously unknown details of the morphology and life history of the nematode are described and illustrated.

The chapter is a comment on Lynn Hunt’s reconsideration, in the same volume, of a crucial moment in the history of human rights when in North America and in France for the first time a ‘self-evidence’ of certain rights of ‘all men’ was claimed in constitutional discourse and documents, and a fundamental shift occurred in the explanation of human rights from a religious framework towards a secular one. The first part of the comment is devoted to the drafting history of the 1776 Declaration of Independence of the United States and to the meaning of the claim to ‘self-evidence’ in the Declaration. In a second part, the author returns to Lynn Hunt’s analysis of the limitations of the actual enjoyment of rights in eighteenth-century North America and France. The third part of the comment deals with the importance, or rather unimportance, of the notion of the self-evidence of human rights in the present age. It is argued that the idea of self-evidence proclaimed in 1776 failed to find general recognition, so that we must search for a new credible foundation of universal human rights.

AbstractThe first investigations of the mite fauna of Sable Island, Nova Scotia, Canada, are reported. Fourteen species have been found. Uropoda orbicularis (Müller) (Uropodidae) and Scarabaspis inexpectatus (Oudemans) (Eviphididae) are newly recorded for North America, Macrocheles nemerdarius Krantz and Whitaker (Macrochelidae) is newly recorded for Canada, and Trichoribates striatus Hammer (Ceratozetidae) is recorded for the first time south of the subarctic zone. Colonization, dispersal, and the zoogeographic origins of the fauna are discussed in the context of the biological, geological, and human history of the island.

Callinectes sapidus is reported here for the first time to state of Paraíba, northeastern Brazil. In Brazil, this species was only known from state of Rio Grande do Sul to the state of Pernambuco, leaving a significant gap in its expected distribution along the coasts of other states in northern and northeastern Brazil, since it has been collected from Venezuela to North America. Two adult female specimens were collected using local fishing gear in the estuary of the Mamanguape River. This new record increases the known distribution of this species.

The chromosomes of Ovis nivicola, described for the first time, exhibit 2n = 52, the lowest diploid number to be reported for wild sheep and goats. The new chromosomal data, together with a review of the fossil history of the genus, lead us to conclude that the bighorned wild sheep (subgenus Pachyceros) evolved their distinctive characteristics while isolated in the ice-free Beringian refugium, and then migrated southward into western North America when the glacial barriers melted, as first suggested by Cowan (1940).

In the history of botany, Adam Zalužanský (d. 1613), a Bohemian physician, apothecary, botanist and professor at the University of Prague, is a little-known personality. Linnaeus's first biographers, for example, only knew Zalužanský from hearsay and suspected he was a native of Poland. This ignorance still pervades botanical history. Zalužanský is mentioned only peripherally or not at all. As late as the nineteenth century, a researcher would be unaware that Zalužanský’s main work Methodi herbariae libri tres actually existed in two editions from two different publishers (1592, Prague; 1604, Frankfurt). This paper introduces the life and work of Zalužanský. Special attention is paid to the chapter “De sexu plantarum” of Zalužanský’s Methodus, in which, more than one hundred years before the well-known De sexu plantarum epistola of R. J. Camerarius, the sexuality of plants is suggested. Additionally, for the first time, an English translation of Zalužanský’s chapter on plant sexuality is provided.
