its malar space length (0.80-0.85 as long as basal width of mandible, 
versus 0.53-0.66 as long in c. prosopis, 0.70 in C. huebriehi, and 0.80 
in C. tomsici), as well as the presence of some short but strong 
wrinkles radiating from the specular periphery (such wrinkles are 
absent in C. huebriehi and C. prosopis and variably defined in C. 
tomsici). 
Field Notes. Los Tigres, in Santiago del Estero Province of the 
Argentine Dry Chaco Biome, suffers an unusually drastic subtropi- 
cal semihumid climatic regimen, with long, rainless winters and only 
sporadically pluvial summers that register thermic maxima of 
45-50° C. The ichneumonid fauna of such localities often is large 
but rarely becomes accessible for capture by hand net. Thus it is not 
surprising that the types series of C. golbachi was collected at Los 
Tigres in the course of a Malaise Trap survey. 
Specific Name. For Professor Rodolfo Golbach of the Funda- 
cion Miguel Lillo at the Universidad Nacional de Tucuman, who 
collected the type series and who has done more than any other 
researcher to document the Argentine entomofauna. 
Acknowledgments 
This research was done under my current National Science Foun- 
dation Grant (BSR-83 13444) and in part supported by previous 
grants from the same agency (DEB-75-22426, GB-6925). Grants for 
field studies in Latin America awarded in 1973, 74, 75, 79, and ’81 
by the Committee for Research and Exploration of the National 
Geographic Society helped substantially in amassing specimens and 
ecological data for Chromocryptus. Additional support was pro- 
vided by Faculty Fellowships from Fordham University awarded 
during the Spring Semester of 1980 and the Fall Term of 1984. 
As a Research Associate of the Florida State Department of 
Agriculture and Consumer Services, I have received generous sup- 
port from the Division of Plant Industry at Gainesville, among 
whose personnel special thanks befit Dr. Howard V. Weems, Jr., 
Dr. Lionel A. Stange, and Mr. Harold A. Denmark. 
My collecting in the Lower Rio Grande Valley of Texas has been 
facilitated by annual permits issued under authority of the Texas 
Parks and Wildlife Department.
