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 , ...

First Record of the Orb-Web Spider Species Argiope sector (Forsskål, 1776) (Araneae: Araneidae) from India

Abstract

The species Argiope sector (Forsskål, 1776) is reported for the first time from India. A brief morphological description and photographic illustrations of the female habitus and copulatory organs are provided, along with a map of its current distribution.
