  One more new species of Chaerilobuthus Lourenço & beigel, 2011 (Scorpiones: Chaerilobuthidae) from Early Cretaceous Burmite Abstract . – The genus Chaerilobuthus is probably the most speciose group among those found in Burmite. In some recent publications most aspects concerning the family Chaerilobuthidae Lourenço & Beigel, 2011 and the genera composing it were precisely discussed; consequently, no further comments will be provided in this contribution. Only one more new species belonging to the genus Chaerilobuthus is described. Chaerilobuthus franzschmidti Lourenço sp . n ., represents the 16th species to be described for this genus confirming therefore the strong speciose characteristic of the group. The new species shows some marked morphological differences when compared to the previous known species, attesting the existence of a major variability within Chaerilobuthus . Lourenço W.

One more remarkable new genus and species of fossil scorpion from Burmese Cretaceous amber associated to the extant family Buthidae (Scorpiones: Buthoidea)

Abstract

The study of a new scorpion specimen from Cretaceous Burmite leads to the descriptions of a new genus and species which once again can be associated to the buthoid lineage and to the family Buthidae C. L. Koch, 1837. The new species shows quite distinct characters, particularly a telson with a rounded-shape, absence of a sub-aculear tooth and the presence of a pseudo annular ring, which is uncommon among buthids in general. Several of its features can associate the new genus to some extant genera such as Butheolus Simon, 1882 and Hottentotta Birula, 1908. The discovery of this new genus and species confirms, once again, the existence of buthid elements within the Burmite fauna.
