Parsimony analysis of morphological data reveals that several species of acarid mites previously assigned to the genera Rhizoglyphus Claparède, Rhizoglyphoides Volgin and Mycetosancassania Klimov, and some undescribed species, represent a monophyletic group within the genus Sancassania Oudemans. The genera Rhizoglyphoides and Mycetosancassania syn. nov. are considered as junior synonyms of the genus Sancassania. Four new combinations are proposed: Sancassania rotundata (Nesbitt, 1944), comb. nov. (from Rhizoglyphus); Sancassania germanica (Berlese, 1921), comb. nov. (from Rhizoglyphus); Sancassania nidicola (Volgin, 1978), comb. nov. (from Rhizoglyphoides); and Sancassania grifolapholiotae (Klimov, 2000), comb. nov. (from Mycetosancassania). Sancassania nidicola and S. germanica are redescribed from type specimens, S. rotundata is redescribed from material from the USA (Michigan). Three new species are described: S. nesbitti, sp. nov., S.���ojibwa, sp. nov. (North America) and S. mironovi, sp. nov. (Northern Asia). This lineage, nidicola(grifolapholiotae(nesbitti, sp. nov. (germanica + mironovi, sp. nov.) (ojibwa, sp. nov. + rotundata))), probably originated in the Palaearctic region from relatively derived Sancassania with short supracoxal setae. The ancestor was probably polyphagous, dispersing on a variety of hosts. We hypothesise that S. nidicola, the most primitive species of the clade, may retain the ancestral ecology. The other members of the clade have specialised to feed on mushrooms and adapted their phenology to exploit this short-lived resource.

Melanoleuca is one of the taxonomically most complicated genera of Agaricomycetes with several taxonomically lineages. The subgenus Urticocystis of the genus Melanoleuca contains species with either urticoid or absent cheilocystidia. In this paper, three new European species, Melanoleuca galbuserae, Melanoleuca fontenlae, and Melanoleuca acystidiata are described as new to science. Melanoleuca galbuserae, related to Melanoleuca stepposa and Melanoleuca tristis, was discovered in alpine grasslands in North Italy. The type specimens and recent collections of Melanoleuca angelesiana, Melanoleuca castaneofusca, Melanoleuca luteolosperma, Melanoleuca pseudopaedida, and Melanoleuca robertiana were sequenced and morphologically examined. Moreover, the related Melanoleuca microcephala and Melanoleuca paedida were included in morphological examination and DNA sequence analyses. All the species were delimited by macro- and micromorphological characters and the multigene phylogenetic analyses of a combined (ITS, rpb2, and tef1) dataset on the basis of the species tree estimation. In accordance with new molecular and morphological data, we suggest taxonomic reappraisal of M. pseudopaedida and M. robertiana, and M. fontenlae and M. acystidiata are proposed as new species. The differences between the type material of M. angelesiana from the USA and European M. angelesiana specimens are discussed.

The hitherto monotypic opilionid genus Fangensis Rambla, 1994 is re-evaluated from new material collected in northern, western and southern Thailand. The original description of F. leclerci Rambla (type material not traceable) was based on specimens belonging to at least three distinct species. Fangensis leclerci is thus redefined and the binomen restricted to specimens from a cave in northern Thailand only. Three new species are described, F. spelaeus, sp. nov. and F. cavernarus, sp. nov. from two caves in western Thailand and F. insulanus, sp. nov. from forests on two islands in southern Thailand. Taxonomic characters are discussed and relationships among Fangensis species and between Fangensis and other cyphophthalmids are evaluated using morphological data and ~4 Kb of molecular data from three loci, two nuclear ribosomal genes and a mitochondrial coding gene. Overall, data indicate monophyly of Stylocellidae and morphological and ribosomal data suggest monophyly of Fangensis, which is in turn divided into two clades, one composed of the three species from northern and western Thailand and the other represented by the species from southern Thailand. Observations on mating in F. leclerci are provided.

Two new species of diminutive, sympatric, lowland, leaf-litter skinks of the genus Tytthoscincus Linkem, Diesmos & Brown from the Sekayu region of Hulu Terengganu, Terengganu State in northeastern Peninsular Malaysia are described on the basis genetic and morphological data. One of the new species, T. monticolus sp. nov., was collected in a hilly riparian area along Sungai (=river) Bubu and is most closely related to an undescribed species from the Tembak Reservoir area. The other, T. keciktuek sp. nov. collected along Sungai Peres, is most closely related to T. perhentianensis Grismer, Wood, & Grismer from Pulau (=island) Perhentian Besar. Sympatry and syntopy of multiple, specialized, unrelated, leaf-litter species of Tytthoscincus was previously only known from upland areas and these new species represent the first example of lowland of sympatry. More importantly, however, these endemic species add to a growing body of research and discoveries that continue to underscore the unrealized biodiversity of the riparian systems of Hulu Terengganu and the Sekayu region and their need for protection and continued study.

The opening of relationships between United States and Cuba could be a drive for a huge increase in the affluence of tourism to Cuba and especially to the coast areas. Cuba has been for many years an important tourist destination for people from many countries, but almost forbidden for US citizens. The proximity of the USA, its amount of population as well as their great acquisition power will increase in a very substantial way the demand for accommodation and other uses in the proximity of the coasts. There will be a need to implement a package of measures that reduce the impact of such sudden increase in the coastal line. On the other hand that augment in tourism could be an opportunity to improve the standard of life of Cubans. The consideration of different possibilities of such development, the analysis of the damages that each one could cause as well as the measures that could avoid, ameliorate or compensate such effects are the goals that are going to be presented in this paper.

In this paper, the changes in the US automobile industry which have occurred over the 1979–86 economic downturn and recovery are examined within the framework of Markusen's profit-cycle theory. When viewing the automobile indusltry as a whole, some of the findings support the profit-cycle theory and others do not. The theory is supported, however, within the context of two distinct automobile industries in the USA—one ‘Fordist’ and the other a Japanese ‘post-Fordist’ system. The Fordist system is entering the negative profit-cycle phase and the post-Fordist system is in the mature phase. The two systems have very different spatial configurations and are likely to have very different economic futures.

Paepalanthus decorus was described by Delia Abbiatti from a single collection of individuals made by Carlos Luis Spegazzini in Uruguaiana, Rio Grande do Sul state, Brazil, deposited at the La Plata Museum. The species is known only from the type specimens, which were unusual for being collected far to the south of the distribution of the other species included in P. sect. Diphyomene. In recent nomenclatural treatments for P. sect. Diphyomene, P. decorus was disregarded, remaining known only from its original publication. Here, we critically evaluate the protologue, type specimens, and the vegetative and floral morphology of this species. As a result, we propose its synonymization under P. flaccidus. A detailed comparison of these species is provided, along with comments on typification, with a lectotype designated for P. flaccidus.

A lively introduction to morphology, this textbook is intended for undergraduates with relatively little background in linguistics. It shows students how to find and analyze morphological data and presents them with basic concepts and terminology concerning the mental lexicon, inflection, derivation, morphological typology, productivity, and the interfaces between morphology and syntax on the one hand and phonology on the other. By the end of the text students are ready to understand morphological theory and how to support or refute theoretical proposals. Providing data from a wide variety of languages, the text includes hands-on activities designed to encourage students to gather and analyse their own data. The third edition has been thoroughly updated with new examples and exercises. Chapter 2 now includes an updated detailed introduction to using linguistic corpora, and there is a new final chapter covering several current theoretical frameworks.

Lizards of the family Diploglossidae occur in moist, tropical forests of Middle America, South America, and Caribbean islands. Our analyses based on new molecular and morphological data indicate that the widely distributed genera Celestus Gray, 1839 and Diploglossus Wiegmann, 1834 are paraphyletic. We restrict the former to Caribbean islands and the latter to South America and Caribbean islands. We assign species in Middle America, formerly placed in Celestus and Diploglossus, to Advenus gen. nov., Mesoamericus gen. nov., and Siderolamprus Cope, 1861. We assign species on Caribbean islands, formerly placed in Celestus, to Caribicus gen. nov., Comptus gen. nov., Celestus, Panolopus Cope, 1862, Sauresia Gray, 1852, and Wetmorena Cochran, 1927. Our phylogenetic tree supports three major clades in the family: Celestinae subfam. nov. (Advenus gen. nov., Caribicus gen. nov., Comptus gen. nov., Celestus, Panolopus, Sauresia, and Wetmorena), Diploglossinae (Diploglossus and Ophiodes Wagler, 1828), and Siderolamprinae subfam. nov. (Mesoamericus gen. nov. and Siderolamprus). Our timetree indicates that the diploglossid lineage originated in the early Cenozoic and established three major centers of diversification in the Americas: Middle America (siderolamprines and one celestine), South America (diploglossines), and Caribbean islands (celestines and diploglossines). The majority of threatened species are on Caribbean islands, with the major threats being deforestation and predation by the introduced mongoose. Molecular and morphological data indicate that there are many undescribed species in this family of lizards.
