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 , ...

First record of a crab spider Xysticus crispabilis Song & Gao, 1996 (Araneae: Thomisidae) from Japan with the first description of a female

ABSTRACT

A crab spider species, Xysticus crispabilis Song & Gao, 1996 (Araneae: Thomisidae), originally described from Anhui, China based on a single male specimen, is newly recorded from Japan. This study represents the second specimen-based record of the species since its original description. Detailed redescriptions of genital morphology, coloration and markings of the male are provided based on fresh material. The previously unknown female is described for the first time. In addition, genital images of the holotype, DNA barcoding data, preliminary molecular phylogeny, and ecological notes are presented.
