HOSTS

Hymenoptera   : Apoidea Latreille, 1802: Sphecidae Latreille, 1802   : Podium   sp. (in laboratory); Hymenoptera   : Apoidea: Crabronidae Latreille, 1802   : Trypoxylon   sp. (in situ). Host association: wooden trap nests were placed in a forested area in Panama by RAC for two weeks (17-31.II.1998), after which one of the nests was found to be occupied and the entrance closed with resin. The occupied trap was taken to the lab at MIUP and both halves of the nest were separated revealing a Podium Fabricius, 1804   larva. The nest was once again closed so the larvae could pupate. Once the larvae reached the pupa stage, a female of T. diophthalma   was placed inside the nest using forceps and the entrance was once again closed leaving the mutillid locked inside the nest for 24 hours, after which the female was removed. Approximately 30 days later a male of T. diophtalma   emerged. Additionally, one female of T. diopthalma   emerged from a species of Trypoxylon Latreille, 1797   in trap-nests placed at Amazonian forest areas in Cotriguaçú, Mato Grosso state, Brazil from August to July of 2017 by Gustavo Júnior de Araújo as part of his PhD fieldwork.

REMARKS

This species is, to the best of our knowledge, the most widely distributed in the genus, being found from Paraguay and Mid-western Brazil to Panama. Its distribution, however, is remarkably “patchy” in between these extremes. It is not clear whether this is due to lack of sampling or its range being indeed disjunct, interrupted near the Amazon and resumed further South. The latter would be a novel distribution for Traumatomutilla   , since most species seem to be widespread and common across large areas – e.g. T. ocellaris ( Klug, 1821)   which is found from Argentina to the southern edges of the Amazonian Forest – or restricted to certain types of environments like T. bifurca ( Klug, 1821)   in the Caatinga and T. guarata Casal, 1969   in the Atlantic Forest.
