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 , ...

Two new species of Harpactea Bristowe, 1939 from Turkey (Araneae: Dysderidae)

ABSTRACT

Two new species, Harpactea bozdaglarensis sp. n. and H. dilekensis sp. n. are described based on both sexes from the Aegean region of Turkey. Both species belong to the rubicunda species group defined for Harpactea due to the characteristics of the copulatory organs and some somatic parts, and H. bozdaglarensis sp. n. resembles H. alexandrae and H. clementi while H. dilekensis sp. n. resembles H. chaniaensis and H. walterdebucki known from the Aegean Islands. Morphometric and meristic characters of the new species and detailed photographs of the copulatory organs are given in the paper.
