 Hemiteles pallidus Ashmead, 1890 (1889). U. S. Natl. Mus., Proc. 12: 406. S. N. syn. The 

 holotype of pallidus has not been found, and it is my belief that its holotype is actually 

 the same specimen as the holotype of rotundiceps. Although Ashmead's description of 

 the propodeum does not agree perfectly with the holotype of rotundiceps, Ashmead is 

 not renouned for his accuracy. There are at least two cases where it is known with 

 certainty that Ashmead redescribed unique specimens from the Belfrage Collection 

 which had already been described by Cresson.
