Range:

Donahue (1993) examined approximately 100 specimens from 
the following MEXICO states (arranged north to south) and months: 

Nuevo Leon (July), 
Tamaulipas (June, July); 
San Luis Potosi (March, May-August, October, November); 
Veracruz (June, August); 
Oaxaca (July, September, November); 
Chiapas (May); and 
Quintana Roo (June-December).

Donahue (1993) reported, for the first time, a record south of Mexico. He examined a single specimen from GUATEMALA, collected 14-18 July 1991, by Peter Hubbell.

Collecting Methods: Frequently is taken at lights in eastern Mexico.

Type Locality: Mexico: Veracruz: Cerro

First U.S. Records

TEXAS: Hidalgo Co., Santa Ana Refuge, 13 November 1971 (1 female); 
TEXAS: Hidalgo Co., Santa Ana Refuge, 23 September 1973 (1 male); 
        both specimens collected by A. & M. E. Blanchard and deposited in the USNM.

Remarks

"This recently described species is remarkably similar in appearance to over a score of wasp-like Neotropical species in several diverse genera. Species of Pseudosphex may be readily distinguished from similar-appearing genera by having a large, fully developed hind-wing discal cell with only three posterior veins (vein M2 absent)." (Donahue 1993)  

E. C. Knudson discovered one third of the records reported here. His initial inquiry about the identity of what was then an undescribed species of Pseudosphex launched Donahue's project to catalog and study the Neotropical Ctenuchinae. (Donahue 1993)
