First host record of Epipompilus (Hymenoptera: Pompilidae) from Brazil and discussion of prey carriage mechanism

ABSTRACT We register for first time the occurrence of Epipompilus tucumanus Evans, 1967 in Brazil, and record the spider Ariadna boliviana Simon, 1907 as its host. The observations were made in the National Park of Chapada dos Guimarães, Mato Grosso, Brazil. The prey carriage mechanism is described for first time for this genus, and we provide a video showing this behavior.

Description of the male of Darditilla araxa (Cresson, 1902) (Hymenoptera, Mutillidae) with geographical distribution, biological notes and key to males of Brazil.

The previously unknown male of Darditilla araxa is here described based on association with females in copula. We also present a map with its geographical distribution, additional biological notes and a key for known Brazilian males of Darditilla.

Five new associations of parasitoids in potter wasps (Vespidae, Eumeninae)

Five new associations of parasitoids in potter wasps (Vespidae, Eumeninae). New associations of host and parasitoids involving potter wasps: Toxophora leucon and Pleurochrysis sp. were found parasitizing Cyphomenes anisitsii, Chrysis sp. (gr. intricans) was found parasitizing Minixi suffusum, Plega beardi was found parasitizing Montezumia pelagica sepulchralis and Macrosiagon sp. was found parasitizing Pachodynerus nasidens.
