Article Reference A new Cangoderces (Araneae, Telemidae) from DR Congo, the first telemid from Central Africa.
Spiders collected as part of a rapid biodiversity survey in lowland forest in Democratic Republic Congo contained a new species of Cangoderces Harington, 1951 (Telemidae). The male of the new Cangoderces wewef sp. n. is characterized by the male palp with a deep triangular dorsal indentation of the bulbus and the apophyses at the base of the embolus. The female is recognized by the shape of the sclerotized spermatheca in the endogyne. The presence of the species in DR Congo fills the huge distribution gap between the species known from South Africa, Kenya and western Africa.

Article Reference New or rare Madagascar tiger beetles - 26. A new species of the genus Pogonostoma Klug from northwestern Madagascar and a revised key to the Pogonostoma (P.) srnkai species-group (Coleoptera: Cicindelidae).
A new species of the genus Pogonostoma Klug, 1835, P. (Pogonostoma) mahimborondrense Moravec & Wiesner sp. nov. is described as new to science from the Mahimborondro protected area in Northern Highlands, northwestern Madagascar. By its unique complex of diagnostic characters, the new species is incomparable to any other species within the genus. It is placed here into the Pogonostoma (P.) srnkai species-group (in the concept presented in the monograph of the genus by Moravec 2007). A revised key to species of the species-group is presented in order to supplement the key in the monograph. Habitus and diagnostic characters of the new species are illustrated in colour photographs. Maps and photos of the occurrence of the new species in Mahimborondro are also presented.

Article Reference Scanning electron microscopy and morphological analysis reveal differences in the otolith morphology of three species of the family Lethrinidae (Teleostei: Perciformes) from Yemen
Otoliths, or ear-stones, are calcareous components in the static-acoustic organs of teleost fishes with a characteristic morphology. As such, they are widely used in fisheries because of the information stored in them concerning, for example, environment, age, and so forth. Otoliths of three lethrinid species Lethrinus borbonicus (Valenciennes, 1830), L. lentjan (Lacepède, 1802), and L. mahsena (Forsskål, 1775) were collected from fish caught along the Red Sea coast of Yemen. Images taken with a scanning electron microscope were used to determine their characteristics. Twenty-two characters were defined to describe the shapes of the otoliths. Eleven measurements of distance between selected features were used for a linear regression and multivariate analysis to characterize the species by their otoliths. The results illustrate ontogenetic changes for different age groups based on the recorded shapes. All three species show a linear relationship between the total length and the morphometric measurements. A linear discriminant analysis shows marked differences between the otoliths of the three species and emphasizes the importance of the measured variables. Otoliths of L. lentjan and L. borbinicus are more similar to each other and differ from those of L. mahsena. A comparison with previously published otoliths of the species studied from other areas confirms an intraspecific uniformity across larger geographic distances, making the characters useful for diagnostic purposes.

Article Reference Cross-taxon congruence of taxonomic and functional beta diversity facets across spatial and temporal scales
An intensively debated issue in ecology is whether the variations in the biodiversity patterns of different biological groups are congruent in space and time. In addition, ecologists have recognized the necessity of accounting for both taxonomic and functional facets when analysing spatial and temporal congruence patterns. This study aimed to determine how the cross-taxon congruence of taxonomic and functional beta diversity varies across space and time, using data from four floodplains at a continental scale. Our general hypothesis was that the congruence between aquatic biological groups, either taxonomic or functional, would decrease with the “between-group” functional distance. Also, we examined how congruence patterns varied across spatial and temporal scales by focusing on how the cross-taxon relationships differ among Brazilian floodplains and between dry/wet periods. Our study comprised information on eight biological groups from the four largest Brazilian river-floodplain systems, and cross-taxon congruence was assessed using Procrustes analysis. Our results show how detailed analyses can reveal different patterns of cross-taxon congruence, and partially support the hypothesis that the strength of cross-taxon congruence is negatively related to between-group functional distance.
