Type-species: Eriopheidole symbiotica Kusnezov. Orig. desig. 



A large genus of harvesting ants for which most sjjecies are found in the arid Southwest. Most 

 species have a dimorphic worker caste with majors or soldiers and minors which are not con- 

 nected by intermediate forms. Only a few species are polymorphic with intermediate sized wor- 

 kers. The soldier is characteristic in having an enormous head, way out of proptortion to the rest 

 of the body, and may function as a seed husker. 



Most species harvest seeds for food and chaff piles are sometimes found around the entrances 

 to the nests. Nests may have craterlike excavations when in exposed soil, or nests may be under 

 stones or other objects and sometimes in rotten wood. Though the main diet normally consists of 

 seeds, most species also feed on other animal food. Most colonies are small with 300 or fewer in- 

 dividuals. 



This is a huge cosmopolitan genus for which few satisfactory subdivisions have been made. A 

 few species had been segregated into subgenera or closely related genera, but the bulk of the 

 species always remained in the subgenus Pheidole. Emery (1921) attempted a group arrange- 

 ment for this large subgenus, but this has met with little acceptance in recent years. It is now 

 the trend to thrust all species into a single imit until satisfactory divisions can be made. The ar- 

 rangement of this genus essentially follows the generic synonomy by Brown (1973) and the 

 treatment of the genus by Gregg (1958). >•
