  First record of Thaumasia Perty, 1833 nursery web spider (Araneae: Pisauridae) preying upon Polistes canadensis (Linnaeus, 1758) (Hymenoptera: Vespidae) in the Neotropical region Abstract Thaumasia Perty, 1833 are opportunistic spiders that inhabit the Neotropical region. This study reports a spider of the genus Thaumasia preying upon Polistes canadensis (Linnaeus, 1758) in semiarid region of Brazil. A spider of the genus Thaumasia was observed moving rapidly from the fountain's water surface to capture an individual of P. canadensis . After successfully capturing the wasp, Thaumasia sp. was observed partially perched on the wall of the fountain, with the prey still on the water surface and trapped by its chelicerae. The pedipalps and chelicerae of Thaumasia sp. manipulated the head of P. canadensis , which stopped moving shortly after being captured, probably because of the action of the spider's venom. The study records a wasp in the diet of Thaumasia based on the ca...

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.
