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 , ...

Rhysida longipes (Scolopendromorpha: Scolopendridae), an unusual prey of Physocyclus globosus (Araneae: Pholcidae)

Abstract

A very young centipede Rhysida longipes (Newport, 1845), approximately 12 mm in total length, is recorded as prey of the synanthropic common spider Physocyclus globosus (Tackzanowski, 1874). The episode was observed into an urban residence in San Antonio de los Baños, Artemisa Province, Cuba. In Cuba this is the first time that a spider is recorded preying upon a centipede.
