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 and noteworthy host records for some North American and Colombian spider wasps (Hymenoptera: Pompilidae)

Abstract

New and noteworthy parasitoid/host records for 47 North American and Colombian species and subspecies of spider wasps (Hymenoptera: Pompilidae) are listed in taxonomic order following the Catalog of Hymenoptera in America North of Mexico (Krombein 1979). Te records represent an extension of previous host studies by Kurczewski and various co-authors. New genus and/or species host records are given for the genera and subgenera Calopompilus Ashmead, Pepsis Fabricius, Hemipepsis Dahlbom, Priocnessus Banks, Entypus Dahlbom, Cryptocheilus Panzer, Priocnemissus Haupt, Caliadurgus Pate, Dipogon Fox, Phanagenia Banks, Auplopus Spinola, Ageniella Banks, Aporus Spinola, Episyron Schiødte, Poecilopompilus Ashmead, Tachypompilus Ashmead, Arachnophroctonus Howard, Pompilinus Ashmead, Arachnospila Kincaid, and Allochares Banks. New host spider families are introduced for Pepsis equestris Erichson (Pycnothelidae), Pepsis mexicana Lucas (Ctenidae), Pepsis cyanescens Lepeletier (Ctenidae), Pepsis lepida Mocsary (Teraphosidae), Priocnessus prominens (Banks) (Teraphosidae), Entypus unifasciatus cressoni (Banks) (Teraphosidae), Priocnemis (Priocnemissus) nigripes (Cresson) (Antrodiaetidae), Dipogon (Deuteragenia) calipterus (Say) (Salticidae), Dipogon (Deuteragenia) sayi Banks (Trachelidae), Auplopus mellipes mellipes (Say) (Dysderidae), Ageniella (Ageniella) accepta (Cresson) species group (Corinnidae), Ageniella (Ageniella) evansi Townes (Zoropsidae), Ageniella (Leucophrus) reynoldsi (Banks) (Salticidae), Ageniella (Priophanes) sp. (Gnaphosidae), Aporus (Aporus) niger (Cresson) (Antrodiaetidae), Episyron conterminus Smith (Nephilidae), Tachypompilus ferrugineus (Say) (Salticidae). Linyphiidae and Philodromidae are new host families for Caliadurgus fasciatellus (Spinola) in North America. Entychides Simon (Euctenizidae) is a new host genus for species in the family Pompilidae. Latrodectus mactans (Fabricius) (Teridiidae) is reported herein for an extremely rare, unidentified host species of Pompilidae.
