Analysis of potential host spider(s) of Pepsis elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini)

Abstract

Five families of spiders (Araneae: Araneomorphae, Mygalomorphae) are reviewed and analyzed as potential hosts of Pepsis elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini). Lycosidae and Atypidae were the least likely host families, afer analysis, with Euctenizidae, Antrodiaetidae, and Halono¬proctidae as more likely host families. Species of Ummidia Torell (Halonoproctidae) and Eucteniza relata (O. P.-Cambridge) (Euctenizidae) were the most likely host genera and species of P. elegans based on myga¬lomorph relationship, equivalent size, and morphological, geographical, ecological, and biological attributes. Smaller sized genera and species of Euctenizidae and Antrodiaetus Ausserer (Antrodiaetidae) were less likely host possibilities.
