We describe a mixed gynandromorph of Xylocopa (Neoxylocopa) nigrocincta from a single specimen from Argentina. The specimen presents bilateral asymmetry, with the right half of its head displaying male characters and the left half displaying female characters; the mesosoma presents male characters mostly in the right half of the prothorax, pronotal lobe and distal half of the fore tibia and in the pubescence of tarsus; the rest of the mesosoma and the metasoma display female features.

This is the first record for the parasitoid association between eulophids and conopids in the carpenter bee Xylocopa augusti Lepeletier. Biological features of Physocephala Schiner are mentioned. A diagnosis for Pediobius williamsoni (Girault) is given and morphological characters are illustrated.

Physocephala wulpi Camras was reared from Xylocopa artifex Smith, Xylocopa augusti Lepeletier, and Xylocapa splendidula Lepeletier. The puparium is described. An overview of conopid host records from the Neotropic Region, and records from Conopidae that develop in Xylocopa, is provided
