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 , ...

New data on spiders (Arachnida, Araneae) of the Arabian Peninsula and the Levant, with new species and records

Abstract

Based on several small collections, new taxonomic and faunistic data on spiders of the United Arab Emirates (UAE), Saudi Arabia, Kuwait, and Lebanon are presented. Six species are described as new to science: Dorceus saif Szűts & Zamani, sp. nov. (♂; Saudi Arabia), Loureedia melanconi Szűts & Zamani, sp. nov. (♂; Saudi Arabia) (both Eresidae), Leptopilos hajarensis Zamani & Marusik, sp. nov. (♀; UAE), Synaphosus dulcicola Zamani & Marusik, sp. nov. (♀; UAE) (both Gnaphosidae), Arctosa formosa Zamani & Marusik, sp. nov. (♂♀; UAE) (Lycosidae), and Prodidomus emiratus Zamani & Marusik, sp. nov. (♀; UAE) (Prodidomidae). In addition, the previously unknown male of Trichothyse golan (Levy, 1999) (Gnaphosidae) is illustrated and described. Finally, one new family record, 16 new generic records and 22 new species records are documented, and the previous record of Sahastata infuscata (Kulczyński, 1901) (Filistatidae) from Yemen is rejected.
