  Image Credit: Creative Commons (some rights reserved) CC BY-NC Photo 111998430, (c) Nicholas Hess Differential Hematotoxic Activity of Southeast Asian Pit Viper Venoms: The Cross-Neutralizing Effect of Available Antivenoms Abstract Background/Objectives : Pit vipers (subfamily Crotalinae) are responsible for a large proportion of snakebite envenoming cases in Southeast Asia. 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 the genus Scorpiops Peters, 1861 from Xizang, China (Scorpiones: Scorpiopidae)

ABSTRACT


A new species, Scorpiops rufus sp.n., from Xizang (China), is described and illustrated. The new species is mainly characterized by reddish-brown color, moderate size, carapace with small and dense granules, 17 (5 eb, 2 esb, 2 em, 4 est, 4 et) external and 6–8 (usually 7) ventral trichobothria in the pedipalp patella, chela with a length/width ratio about 2.5 in males and 2.6 in females, pedipalp chela fingers are scalloped in both sexes, pectinal teeth count 6 or 7 in males and 5 or 6 in females, pectinal fulcra absent. This brings the total number of species of Scorpiops Peters, 1861 recorded in China to 34.
