Aetosauria is a clade of heavily armored, quadrupedal omnivorous to herbivorous archosaurs known from the Late Triassic across what was the supercontinent of Pangea. Their abundance in many deposits relative to the paucity of other Triassic herbivores indicates that they were key components of Late Triassic ecosystems. However, their evolutionary relationships remain contentious due, in large p...

A detailed comparison of all characters described for Centrolene ritae Lutz shows that it is a senior synonym of Cochranella oyampiensis Lescure and Centrolenella ametarsia Flores. The holotype of C. ametarsia is designated as neotype of C. ritae.

A new species of Megischus Brullé from China, Megischus aplicatussp. n.,is described and illustrated. A key to the Chinese species of Megischus is added. The holotype is deposited in the Parasitic Hymenoptera Collection of Zhejiang University, Hangzhou.

Oideterus inaequalis sp. nov. is described from Ecuador and compared with the holotype of O. lobicollis. The latter is excluded from the fauna of Ecuador. A key to known females of Oideterus is provided.

Examination of the type series (holotype and single paratype) of Eutheia siamensis Franz (Thailand) revealed that it was composed of two different species, belonging not only in different genera, but also tribes. The holotype is a representative of Cephennomicrus Reitter (Cephenniini), while the paratype is a species of Paraneseuthia Franz (Eutheiini). Consequently, E. siamensis is redescribed ...

The holotype of Libellulosoma minuta, until now regarded as the unique specimen of this monotypic genus and considered lost for half a century, was found again in the dragonfly collection of the Muséum National d'Histoire Naturelle in Paris. A second specimen, also from Madagascar (probably East Madagascar) was found in the collection René Martin together with the holotype. A redescription, inc...

Pseudophilautus stellatus (Kelaart 1853) has been rediscovered from the Peak Wilderness, Central Hills of Sri Lanka. The species, till now known only from its lost holotype, was the first shrub frog described from Sri Lanka, and had not been reported since then. It was thought to have become extinct for nearly 157 years, being the amphibian species "lost" for the longest amount of time. Here we...

BACKGROUND Centrosaurine ceratopsids are well known from the middle Campanian Upper Two Medicine Formation of Montana. Four taxa have been named: Brachyceratops montanensis, Rubeosaurus ovatus, Einiosaurus procurvicornis, and Achelousaurus horneri. Rubeosaurus has been historically the most enigmatic of these taxa; only two specimens, the holotype caudal parietal bar and a referred incomplete s...
