  Examining ecological niche for six species of whip spider in Colombia  Abstract The conditioning variables for the establishment of Amblypygi populations and their ecological interactions are currently poorly studied. Delving deeper into this can help to conserve this group of short-range distribution species, which are useful as a model in biogeographic research. In this study, we evaluated the distribution and overlapping patterns of ecological niche in six species of amblypygids ( Phrynus araya , P. panche , P. pulchripes , Heterophrynus batesii , H. boterorum , H. cervinus ) in the Andean and Amazonian ecosystems of Colombia, revealing a clear biogeographic segregation driven by environmental gradients: Phrynus species were associated with inter-Andean valleys with high thermal and water seasonality.  While the Heterophrynus occupied more stable and humid conditions of foothills and middle elevations. Overlap analyses showed significant divergence (e.g., D=0.105 b...

An exceptional new genus of fossil scorpion from Burmese Cretaceous amber belonging to the family Palaeoburmesebuthidae Lourenço, 2015

Abstract. – An exceptional new genus and species of fossil scorpion, Paranotaburmesebuthus schmidti Lourenço gen. n., sp. n., is described from the Cretaceous amber of Myanmar (Burma). This is the fourth genus of fossil scorpion from Burmite described in the family Palaeoburmesebuthidae Lourenço, 2015. The new genus is characterized by a combination of several morphological features and in particular by the presence of lateral extensions in tergites I to VI recalling paranota. The description of the new genus and species suggests new evidence on the phylogenetic position of certain Burmite amber scorpions and confirms, once again, the considerable degree of diversity in the Burmese amber-producing forests.
