Envenomation by these snakes commonly causes hematotoxic effects, including platelet dysfunction and coagulation disturbances. Although antivenom remains the mainstay of treatment, species-specific antivenoms are not available for several regional pit viper species. This study evaluated the hematotoxic activities of selected Southeast Asian pit viper venoms and the cross-neutralizing capacity of commercially available antivenoms.  Methods : Venoms from five medically important pit viper species— Calloselasma rhodostoma ,  Trimeresurus albolabris ,  T. hageni ,  T. purpureomaculatus , ...

On the genus Ananteris Thorell, 1891 in French Guiana, with description of a new species (Scorpiones: Ananteridae)

Abstract

One new species belonging to the genus Ananteris Thorell is described from the foot of the Mount Grand Matoury, French Guiana. The description of this new species brings further evidence about the biogeographic patterns of distribution presented by most species of the genus Ananteris, which are highly endemic in many natural formations of South America and in particular in French Guiana. The new taxon described here raises the number of known species for the genus Ananteris in French Guiana to 13, and the total number of currently recognized species for the genus to 100. A geographical distribution map of the species occurring in French Guiana is presented and an identification key is proposed.
