A male collected at the USDA Lab in Dade Co., Florida on Nov. 
6, 1981 by Dr. Landolt and now in the MCZ most closely resembles 
hubrichi, originally described from Argentina. The specimen is 
primarily reddish brown with limited yellow maculations as follows: 
the pronotum rimmed both anteriorly and posteriorly, the mesepis- 
ternum in part, a line in front of the parategula, and the scutellum 
laterally and metanotum entirely. The second metasomal tergum is 
not darker than the successive terga. However, this pattern is either 
developed or approached in specimens determined as other subspe- 
cies in the collections of the MCZ (most of the specimens listed in 
Giordani Soika, 1975, as being in the USNM are in fact in the MCZ, 
and there are numerous other similar errors), CU and USNM. Care- 
ful examination of series of these subspecies showed discrepancies 
with Giordani Soika’s (1975) key, as well as transitional forms and 
distributional overlap. I have seen specimens of nine of the ten 
subspecies of argillaceum in the collections of the MCZ, CU and 
USNM, and cannot consider them distinct. The following discussion 
documents the synonymy. 
The difficulties begin with the first couplet of Giordani Soika’s 
subspecies key, which gives as alternatives (my translation):
