Summary 
The mesostenine genus Chromocryptus comprises trachysphyroid 
ichneumonids with pyramidal clypeus; strongly sculptured mesoscu- 
tum; axillus near hind margin of wing; 1st gastric tergite with a 
palpable basolateral expansion; 2nd gastric tergite with large, dense 
punctures; and with a short, straight, compressed ovipositor. There 
are 1 1 species: Chromocryptus planosae (Fitch) in the northeastern 
United States; C. weemsi (Porter) in Florida; C. mesorufus Cushman 
in Florida, Texas, and Mexico; C. vandykei Townes in Califor- 
nia; C. teres n. sp. in Peru’s Coastal Desert; C. alvaradoi n. sp., C. 
golbachi n. sp., C. prosopis n. sp., and C. tomsici n. sp. in northwest 
and north-central Argentina; C. huebrichi (Brethes) in south Brasil 
and adjacent Argentina; and C. poecilma (Porter) from Minas 
Gerais, Brasil. Biomes inhabited by different species of Chromo- 
cryptus include Temperate Deciduous Forest, Tropical Wet Forest, 
Subtropical Cloud Forest, lowland Subtropical Thorn Scrub, and 
high Andean Desert. Several Chromocryptus have been reared as 
apparently polyembryonic parasites from moth cocoons (mostly 
Lasiocampidae) attached to bark. 
Much of the material on which this revision is based was collected 
in northern Argentina during frequent periods of collaboration with 
the Fundacion Miguel Lillo and the Facultad de Ciencias Naturales 
of the Universidad Nacional de Tucuman. I am particularly grateful 
to Professor Rodolfo Golbach and to Dr. Abraham Willink of these 
institutions. 
Finally, I thank Mr. Thomas J. O’Neill of Fordham University 
for his consummate skill in preparing many of the illustrations for 
this article and for his assistance on several South American 
fieldtrips.
