Five new species of the genus Cotycicuiara Galileo and Martins are described and illustrated: C. oicepe sp. nov., from Trinidad and Tobago; and from Brazil C. multicava sp. nov., (Minas Gerais); C. pertusa sp. nov., (Rio de Janeiro, Santa Catarina); C. nivaria sp. nov., (Minas Gerais, Espírito Santo); C. chionea sp. nov., (Rio de Janeiro). A revised key to species is provided.
The huntsman spider genera Sparianthina Banks, 1929 and Anaptomecus Simon, 1903 are reviewed. The type species of Sparianthina, Sparianthina selenopoides Banks, 1929, is redescribed, illustrated, and recorded from Costa Rica for the first time; a lectotype and paralectotype are designated. Three species are transferred to the genus: Sparianthina pumilla (Keyserling, 1880) comb. n. from Heteropoda Latreille, 1804 (lectotype and paralectotype are designated), Sparianthina rufescens (Mello-Leitão, 1940) comb. n. from Anaptomecus and Sparianthina milleri (Caporiacco, 1955) comb. n. from Macrinus Simon, 1887. The ♂ of S. rufescens (Mello-Leitão, 1940) comb. n. and the ♀ of S. milleri comb. n. are described for the first time. Three new species are described: Sparianthina adisi sp. n., S. deltshevi sp. n., and S. saaristoi sp. n. The male and female of Anaptomecus longiventris Simon, 1903 are described for the first time and the species is recorded from Panama for the first time. Two new species are described: Anaptomecus temii sp. n. and A. levyi sp. n. Keywords: Taxonomy, re-description, transfer, review
Zwei Brombeerarten der Sektion Rubus ser. Glandulosi (Wimmer & Grabowski) Fokke werden neu beschrieben. Beide sind in Thüringen und Nordbayern verbreitet: Rubus exarmatus H. E. Weber & W. Jansen spec. nov. und Rubus perlongus H.E. Weber & W. Jansen spec. nov. Die Arten sind durch Fotos ihrer Holotypen abgebildet, ihre bekannte Verbreitung ist durch Rasterkarten dargestellt.
A new feature for the separation of Trochosa spinipalpis and T. terricola males (Araneae, Lycosidae)
(2006)
A new feature on the tip of the palp, which enables the separation of male Trochosa spinipalpis (F. O. P.-Cambridge, 1895) from T. terricola Thorell, 1856, is described. T. terricola exhibits a hairless strip on the tip of the palp, while T. spinipalpis lacks this feature and has long hairs on the whole palp.
Drassodes lapidosus und Drassodes cupreus (Araneae: Gnaphosidae) - eine unendliche Geschichte
(2006)
Drassodes lapidosus and Drassodes cupreus (Araneae: Gnaphosidae) – a never-ending discussion. According to PLATNICK (2006) the taxa Drassodes lapidosus (Walckenaer, 1802), the type species of the genus Drassodes (Westring, 1851), and Drassodes cupreus (Blackwall, 1834) are two valid species. However, GRIMM (1985) merged them into one taxon. Different taxonomists have separated these species by the positions of the teeth in the frontal margin of the chelicerae and by the proportions of the palpal segments in males. Females are separated by the proportions of different features in the epigyne. The altitude at which they occur is used for separation, too. The aim of this paper is to discuss whether these characteristics really allow the separation of these two taxa. In order to solve this taxonomical problem, 116 male and 108 female specimens from Central Europe were examined. The variation of the mentioned characters is shown. Spearman’s rho correlations and factor analyses are presented. The results show that there are transitions between the two taxa D. lapidosus and D. cupreus and, thus, they cannot be separated using the diagnostic features currently available.
Adult females of the five Central European wolf spiders Trochosa hispanica Simon, 1870, T. robusta (Simon, 1876), T. ruricola (De Geer, 1778), T. spinipalpis (F. O. P.-Cambridge, 1895), and T. terricola Thorell, 1856 were morphologically analysed. We defined sets of continuous and binary (presence/absence) variables. Continuous data of various epigynal and carapace dimensions were subjected to Principal Components Analysis (PCA). Using the PC loadings each individual was plotted along the PC axis in order to find gaps/overlaps between the species. The binary data sets were subjected to Hierarchical Cluster Analysis (HCA) in order to find characters that clearly separate the five Trochosa species. Using PCA only individuals of T. robusta and T. ruricola and of T. robusta and T. hispanica could be separated from each other. Using HCA all five species could clearly be separated by epigynal and vulval characteristics.
Thirteen species of skippers (six newly described; Lepidoptera: Hesperiidae: Hesperiinae: Hesperiini) from higher elevations of Mexico and Central America are reviewed. These are included in four genera (one newly described), some with proposed new combinations. Onespa Steinhauser, 1974, originally described as monotypic, is shown to include three species in addition to its type species, Onespa nubis Steinhauser, 1974. One of these, Atrytone gala Godman, 1900, that has been misplaced in several genera since its description, represents a new combination. The other two species, distributed in montane habitats in northwestern Mexico and in Costa Rica, are described as new. Buzyges Godman, 1900, distributed in Mexico and Central America and also formerly considered monotypic, is shown to embrace four species. Besides the type species, Buzyges idothea Godman, 1900, two species long placed in Poanes Scudder, 1872, Pamphila rolla Mabille, 1883, and Poanes benito Freeman, 1979, are included as new combinations. Another species, known only from Costa Rica, is described as new. These are united by several superficial characters, but especially by genital morphology of both sexes. Librita Evans, 1955, was described to include three species of which one, Librita raspa Evans, 1955, was subsequently removed. Augiades heras Godman, 1900 is here also removed from Librita and placed in a new genus with three previously undescribed species. This completes the disintegration of Librita, which is now monotypic. The four genera, although exhibiting similarities suggesting potential alliance, differ in their unique combinations of several superficial and genital traits from each other and other hesperiine skippers.
