The chrysidid tribe Elampini comprises a diverse group of genera. There are a number of small (1–3 species) highly derived genera in this group. Nearly all of these occur in 2 regions, southwestern North America and the area comprising the Middle East, southern USSR and North Africa. The small North American genera are Hedychreides Bohart, Microchridium Bohart, Minymischa Kimsey, Pseudolopyga Bodenstein and Xerochrum Bohart. Those in the latter region include: Haba Semenov, Prochridium Linsenmaier and the new genus, Adelopyga, described below. One genus, Muesebeck- idium Krombein, occurs in both North and South America. The following abbreviations are used: F = flagellomere, MOD = midocellus diameter, PD = puncture diameter, Rs = forewing radial sector, and S = gastral sternum.
