Mosasauroids are conventionally conceived of as gigantic, obligatorily aquatic marine lizards (1000s of specimens from marine deposited rocks) with a cosmopolitan distribution in the Late Cretaceous (90-65 million years ago [mya]) oceans and seas of the world. Here we report on the fossilized remains of numerous individuals (small juveniles to large adults) of a new taxon, Pannoniasaurus inexpectatus gen. et sp. nov. from the Csehbánya Formation, Hungary (Santonian, Upper Cretaceous, 85.3-83.5 mya) that represent the first known mosasauroid that lived in freshwater environments. Previous to this find, only one specimen of a marine mosasauroid, cf. Plioplatecarpus sp., is known from non-marine rocks in Western Canada. Pannoniasaurus inexpectatus gen. et sp. nov. uniquely possesses a plesiomorphic pelvic anatomy, a non-mosasauroid but pontosaur-like tail osteology, possibly limbs like a terrestrial lizard, and a flattened, crocodile-like skull. Cladistic analysis reconstructs P. inexpectatus in a new clade of mosasauroids: (Pannoniasaurus (Tethysaurus (Yaguarasaurus, Russellosaurus))). P. inexpectatus is part of a mixed terrestrial and freshwater faunal assemblage that includes fishes, amphibians turtles, terrestrial lizards, crocodiles, pterosaurs, dinosaurs and birds. © 2012 Makádi et al.

Previously unrevised types of several species of the genus Thinodromus Kraatz, 1857, Trogophloeus montiumdraconis Scheerpeltz, 1974, Trogophloeus rhodesianus Scheerpeltz, 1974 and Trogophloeus sudanensis Scheerpeltz, 1974, are examined, redescribed and illustrated, all primarily from the southern half of continental Africa. Lectotypes are designated for Trogophloeus tibialis Fauvel, 1907 and Trogophloeus capensis Bernhauer, 1934, the latter is found to be conspecific with Trogophloeus montiumdraconis Scheerpeltz, 1974, syn. nov. The previously unknown female of Thinodromus dasys Gildenkov, 2000 and the male of T. facilis Gildenkov, 2000 are documented, T. kedougouensis Makranczy, 2009, syn. nov., is conditionally placed in synonymy with T. nigerius Gildenkov, 2000. Two species are described as new: T. gildenkovi sp. nov. from Botswana (North- East) and T. meridionalis sp. nov. from South Africa (KwaZulu-Natal prov.). The external morphologies of all these species are illustrated by SEM images, some by colour habitus photographs, and all terminalia and genitalia by line drawings. Source

A significant proportion of taxa was described from a single specimen; however, miscellaneous influences are known to alter a phenotype, raising the question of the validity of taxa that have been reported only once in the history. The purpose of the present study was to highlight one of the possible sources of the high number of once-only taxa; the parasitogenic phenotype. I report observations made using noninvasive X-ray microtomography, which provides direct evidence of the presence of mermithid nematodes in the gaster of certain type specimens, demonstrating that two of the three once-only Myrmica taxa were described on the basis of mermithogenic phenotypes. Microtomographic images show that M. symbiotica (MENOZZI, 1925) was described on a mermithogenic phenotype; so, I propose junior synonymy with M. scabrinodis NYLANDER, 1846. The formerly reported mermithid infestation of M. myrmecophila WASMANN, 1910 holotype, and synonymy with M. sulcinodis NYLANDER, 1846 is confirmed. Though the holotype of Myrmica schenckioides BOER & NOORDIJK, 2005 proved to be uninfected, the malformed features of the type specimen raise the possibility that it is a teratological case. Source


Porcelloderes impenetrabilis gen. & sp. n. (Hemiptera: Heteroptera: Reduviidae: Physoderinae) is described, based on males, females, and larvae from different localities in northeastern Tanzania. The new discovery extends the range of the subfamily (previously known from the Oriental Region and the Pacific, from Madagascar and neighbouring islands, and from Central and South America) to mainland Africa. In contrast to all previously described physoderine species, the new species is apterous, which is probably a result of neoteny; the neotenous aptery and its morphological consequences are discussed. The diagnosis of Physoderinae is extended in order to make it applicable to apterous taxa. In all examined specimens including larvae, the body surface is covered by a firm incrustation of soil, deposited between the long setigerous tubercles. This is the first record in the subfamily Physoderinae of camouflaging by application of material on the body, and the first report of such behaviour in the adult stage in Reduviidae. Source


Within the tribe Pipistrellini, the genus Glischropus is very close to the genus Pipistrellus both in its external morphology and chromosomal features but can be unequivocally distinguished from the latter by the presence of thumb pads and the position of the second incisor. One of the two known species, G. tylopus was thought to have a wide distribution range from Myanmar to the Philippines, while the other, G. javanus is only known from Java. Recently collected Cambodian specimens of Glischropus are distinguished from their congeners by longer forearm and cranial features (the shape of the skull and the upper incisors and certain craniodental measurements) and are consequentially, described here as a new species. Based on thorough examination of the available museum material, it can be concluded that all specimens of G. tylopus previously collected in the Indochinese zoogeographic subregion are in fact representatives of this new species, while G. tylopus in a strict sense is restricted in the mainland to south of the Isthmus of Kra.
