Trachelas L. Koch, 1872 is a large and diverse genus of sac spiders, originally placed in the family Drassidae Koch. Simon (1897) transferred Trachelas to the family Clubionidae Wagner, 1887 in the Tracheleae group Karsch, 1880, under the subfamily Corinninae Karsch, 1880. Corinninae was elevated to family rank by Lehtinen (1967). Lehtinen (1967) did not refer to the Trachelineae group in that ...

This article examines the different roles played by field and non-field naturalists in constructing cultures of nature and in the dispute to construct scientific careers in the nineteenth century. Based on the concept of "threshold experience," it looks at little-explored aspects of Peter Wilhelm Lund's paleontological work (1801-1880) [corrected] in Brazil and its international impact.

The classical Center-Focus problem posed by H. Poincaré in 1880’s asks about the characterization of planar polynomial vector fields such that all their integral trajectories are closed curves whose interiors contain a fixed point, a center. In this paper we describe a new general approach to the Center Problem.

The genera Clivinopsis Bedel 1895 and Torretassoa Schatzmayr & Koch 1933 have been recorded in Iraq for the first time. New records of several species of Dyschirius Bonelli 1810 Dyschiriodes Jeannel 1941 (Dyschiriini W. Kolbe 1880) and Clivina Latreille 1802 (Clivinini Rafinesque 1815) are given. The identification key to the species of Dyschiriini from Iraq is provided.

The authors have constructed a brief timeline of major clinical research related to hereditary spastic paraplegia (HSP). This timeline summarizes the evolution of HSP research, from the first clinical descriptions by Adolf von Strümpell in 1880 to the present day, with the transformation of these diseases into a rapidly-growing and heterogeneous group of neurogenetic diseases.

A list of species of the water mitegenus Lebertia Neuman, 1880 known from Turkey is provided, based on bibliographical data and results from recent field work, mainly in the Southwestern part of the country.

A collection of Paguroidea recently obtained during deep-water expeditions along the coast of Brazil, forms the basis of this report. Of the 14 species reported from Brazil, 11 represent range extensions to the south, and one, Michelopagurus atlanticus (Bouvier, 1922), is a first record for the western Atlantic. The specimens were compared with types and western Atlantic materials deposited in ...

The spider genus Selenops Latreille, 1819 occurs in both the Old World and New World tropics and subtropics and contains nearly half of the species in the family Selenopidae Simon, 1897. In this paper the members of the genus Selenops found in North America, Central America, and on islands of the Caribbean are revised, excluding Cuban endemics. No taxonomic changes are currently made to the spe...
