Abstract

MARTINEZ, Juan J.  and  TORRETTA, Juan P.. New records of Messatoporus (Hymenoptera: Ichneumonidae) from Argentina, with comments on its biology. Rev. Soc. Entomol. Argent. [online]. 2015, vol.74, n.3-4, pp.213-216. ISSN 0373-5680.

New records of the genus Messatoporus Cushman from Martín García Island, Argentina, are provided and the species Messatoporus transversostriatus (Spinola) is recorded for the first time from Argentina. This species was reared from nests of Isodontia costipennis (Spinola) (Sphecidae), Pachodynerus guadulpensis (Saussure) and Monobia angulosa Saussure (Vespidae). These records represent the first detailed biological observations for a neotropical species of the genus and are the first association of Messatoporus with sphecid nests.

Keywords : Cryptinae; Hostparasitoid association; Messatoporus transversostriatus; New records.
