Genus PARANCISTROCERUS Bequaert 



Ancistrocems subg. Parancistrocerus Bequaert, 1925. Amer. Ent. Soc, Trans. 51: 64. 

 Type-species: Odynerus {Ancistrocerus) fulvipes Saussure. Orig. desig. 



Most species make their nests in abandoned borings of other insects in twigs, stems or wood, 

 in artificial borings in wood, in abandoned mud-dauber nests and insect galls, and in abandoned 

 borings of ground-nesting wasps or bees in the ground. One species constructs multicellular mud 

 nests attached to branches or twigs. The species have been reported as preying only upon larvae 

 of Lepidoptera. 



All species have a complex symbiotic relationship with saproglyphid mites, each wasp having a 

 host-specific mite. Each species of wasp has developed an acarinarium, a chamber at the base of 

 the second abdominal tergum which is covered by the apex of the first tergum. The hypopial 

 stage of the mite congregates in large numbers in the acarinarium.
