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 , ...

A new species of Phlogiellus Pocock, 1897 from China (Araneae: Theraphosidae)

Abstract

A new species of theraphosid spider, Phlogiellus hakka Yao, Gong, Yu & Liu, sp. nov., is described from Fujian Province, southern China, based on both male and female specimens. This represents the first record of the genus Phlogiellus Pocock, 1897 from Fujian Province. Detailed morphological descriptions, supported by digital images (including SEM), and information on its natural habitat are provided. The discovery of P. hakka sp. nov. fills a significant distributional gap along the southeastern coast of China and is discussed in relation to the known biogeography of the genus in the region.
