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 lat- 
ter 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. 
Adelopyga Kimsey, new genus. 
Type species: Adelopyga huberi Kimsey, new species. 
Etymology: Adelo - “obscure”, pyga - “tail”, taken from Holopyga, 
f., Grk. 
Diagnosis. Scapal basin smooth with large punctures laterally 
and slightly rugose medially; F-I shorter than II, and pedicel; man- 
dible with 1 subapical tooth; mesopleuron rounded, with distinct 
scrobe and oblique scrobal sulcus; female foretarsal claws edentate, 
mid and hindtarsal claws with single subparallel tooth; apical female 
fore and midtarsomeres curled, appearing prehensile; hindcoxa 
without dorsobasal carina; forewing Rs tiny, less than one-sixth
