Article Reference Diverse assemblages of Mid Devonian megaspores from Libya.
A restudy of Devonian palynological assemblages of samples from the A1-69 borehole, drilled in the Ghadamis Basin, western Libya, North Africa has led to the discovery of numerous well-preserved megaspores amongst abundant miospores, rare acritarchs and rare chitinozoans. Thirteen samples from base to top, 1496 ft (456 m) up to 965 ft (294 m), contain the richest Devonian megaspore assemblages from northwestern Gondwana. The section is dated by a rich diverse miospore assemblage indicating the presence of the upper part of the AD pre-Lem Biozone up to the lower part of the TCo Oppel Zone, ranging from a latest Eifelian or earliest Givetian age up to a latest Givetian or an earliest Frasnian age. Seventeen megaspore taxa have been identified. Among them, two new species (Biharisporites lugardonii and Lagenicula milleri) and four new varieties (Corystisporites acutispinosus var. acutispinosus and var. bullatus, Heliotriletes longispinosus var. longispinosus and var. radiatus) are described. One new possible megaspore species is also described: Verruciretusispora labiosa sp. nov. One core sample (1293 ft, 394 m) contains several specimens of very large megaspores (ca. 1 mm), the largest known from Devonian localities (except for one specimen observed in the Givetian from Belgium). Among the 17 megaspore taxa from Libya, 6 are present on the Euramerican Continent. This observation is in accordance with previous palynological conclusions that favour the absence of palaeogeographic barriers between the Euramerican and Gondwanan continents that are suggested to be grouped together in a “Pre-Pangea” land mass.

Article Reference Human-Induced Expanded Distribution of Anopheles plumbeus, Experimental Vector of West Nile Virus and a Potential Vector of Human Malaria in Belgium
For the majority of native species, human-created habitats provide a hostile environment that prevents their colonization. However, if the conditions encountered in this novel environment are part of the fundamental niche of a particular species, these low competitive environments may allow strong population expansion of even rare and stenotopic species. If these species are potentially harmful to humans, such anthropogenic habitat alterations may impose strong risks for human health. Here, we report on a recent and severe outbreak of the viciously biting and day-active mosquito Anopheles plumbeus Stephens, 1828, that is caused by a habitat shift toward human-created habitats. Although historic data indicate that the species was previously reported to be rare in Belgium and confined to natural forest habitats, more recent data indicate a strong population expansion all over Belgium and severe nuisance at a local scale. We show that these outbreaks can be explained by a recent larval habitat shift of this species from tree-holes in forests to large manure collecting pits of abandoned and uncleaned pig stables. Further surveys of the colonization and detection of other potential larval breeding places of this mosquito in this artificial environment are of particular importance for human health because the species is known as a experimental vector of West Nile virus and a potential vector of human malaria.

Article Reference A new species of Kriptobaatar (Multituberculata): the first Late Cretaceous mammal from Inner Mongolia (P.R. China)
Multituberculates are the best represented mammals of the Late Cretaceous in Asia and most of them are from Outer Mongolia. The djadochtatherioidean multituberculate Kr)ptobaut~im- andihuensis n. sp. is described on the basis of two skulls froin the Upper Cretaccous localiiy of Bayan Mandaliu (Inner Mongolia, People's Republic of China). The main characters that differentiate it from tlie type species K. dashzevegi Kielan-Jaworowska, 1970 are: the base of the zygomatic arch situated at the level of tlie anterior root of the P4 and the narrow anterior extent of the orbit, the "V" shape of the palatoinaxillary suture between the tlvo major palatine fonmina, the high and thick part of the dentary under the mandibular diastema. the long and low part of the dentary iinder the mandibular notch, the anteroposteriorly short coronoid process. the presence of 5 cusps on the middle row of Ml and on the labial row of ml, the long p4. the Iiigh ratio p4:ml length, and the robust il. The presence of this species in lnner Mongolia extends the palacogeographical distribution area of the djadochtatherioideans to the soutliern part of the Gobi Basin. Neveiiheless, morphological differences between K. tnandahitensis from lnner Mongolia and K. dushzevegi from Outer Mongolia suggest a palaeogeographical isolation within the Djadochtatherioidea group during the Campanian.

Article Reference Macrocranion germonprae n. sp., insectivore proche de la limite Paléocène-Eocène en Belgique
La nouvelle espèce Macrocranion germonpreae du Membre de Dormaal (Groupe de Landen, Belgique) est décrite sur la base de dents jugales isolées. Cet insectivore érinacéomorphe est comparé aux autres espèces du genre Macrocranion d'Europe et d'AmCrique du Nord. M. germonpreae possède les caractères morphologiques d'un Dormaaliinae primitif.
