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 , ...

Notes on Berinda Roewer, 1928 (Araneae: Gnaphosidae), with description of two new species from Turkey

Abstract

Two new species of the gnaphosid spider genus Berinda Roewer 1928 are described from Turkey: B. anlasi sp. nov. (♂; Gerger District, Adıyaman Province) and B. orgeli sp. nov. (♂♀; Hassa District, Hatay Province). Additionally, the first description of the female and a redescription of the male of B. cooki Logunov, 2012 are provided, along with the first record of B. infumata (O. Pickard-Cambridge, 1872) from Turkey. Images of the habitus and copulatory organs of these species are also included.
