Description of the male of Xystromutilla bucki Suárez, 1960 (Hymenoptera, Mutillidae), including new information on the biology of the genus

Abstract

The male of Xystromutilla bucki Suárez, 1960 is described and associated with the female based on couples reared from trap-nests occupied by Auplopus subaurarius Dreisbach, 1963 (Hymenoptera: Pompilidae). Information on the diapause of X. bucki and Pseudomethoca nr. chontalensis (Cameron, 1895) (Hymenoptera: Mutillidae) is presented. Seasonal and annual variation in the abundance of X. turrialba Casal, 1969 are also given.

Trap-nesting biology of an ectoparasitoid spider wasp, Auplopus subaurarius (Hymenoptera: Pompilidae): the importance of wooded environments for niche generalist species

“…One of these species is Auplopus subaurarius Dreisbach, 1963, a solitary wasp, which builds their nests in preexisting cavities, where the females construct a varied number of brood cells, which have a barrel shape and are made of clay (Buschini et al, 2007;Nether et al, 2019;Buggenhagen, 2016). Auplopus subaurarius has been found nesting in the Araucaria Forest, one of the phytophysiognomies of the Atlantic Forest biome (Buschini et al, 2007;Buschini and Woiski, 2008;Iantas et al, 2017;Cambra et al, 2017Cambra et al, , 2021. These forests can be found in the southern region of Brazil and are characterized by the presence of the conifer Araucaria angustifolia (Bertol.)…”
