Infrageneric affinities 
Chromocryptus forms a compact genus in which establishment of 
subgenera or species groups seems as yet unnecessary. Little has 
been discovered about the ancestral or derived nature of the states 
of features used to separate these species, so that phylogenetic anal- 
ysis within Chromocryptus would be premature. 
Nonetheless, some idea of relationships within the genus may be 
derived from the following hierarchically indented schema: 
I. Ovipositor stout, its tip not sagittate; fore tibia swollen; 
clypeus approximately symmetric, convex to bluntly pyra- 
midal C. alvaradoi. 
II. Ovipositor slender and delicate, its tip sagittate; fore tibia not 
inflated; clypeus asymmetrically and nasutely pyramidal. 
1. Mesopleuron with conspicuous, long, rather regular wrin- 
kles that radiate extensively from speculum; mesoscutum 
with some smooth areas between puncto-reticulation on 
both median and lateral lobes 
C. poecilma, C. teres. 
2. Mesopleuron without or with only short wrinkles radiating 
from speculum; mesoscutum usually without smooth 
areas among the coarse sculpture C. planosae, 
C. mesorufus, C. weemsi, C. vandykei, C. huebrichi, 
C. prosopis, C. golbachi, and C. tomsici. 
Plausibly, Chromocryptus alvaradoi diverged early from the 
Chromocryptus evolutional line. Specializations, possibly asso- 
ciated with parasitism of small hosts and with a newly acquired 
polyembryonic life style, then led to the origin of a cluster of smaller 
species with more delicate ovipositors. More recently, this latter 
category has subdivided into the weakly differentiated Poecilma and 
Planosae complexes. 
Collections Examined 
Listed below in alphabetic order are the collections which fur- 
nished material for this research and/or in which type specimens are 
to be deposited. I refer to institutional collections by the name of the 
city in which they are located and to individual collections by the 
surname of their owner.
