or no groove; propodeal teeth tapering and apically pointed (fig. 14); 
(fig. 7) leg joints, and apical rim of T-III often white or hyaline; 
paramere digitate and or lobate (fig. 19); cuspis broadly rounded, and 
digitus equal to or shorter than cuspis and apically rounded (fig. 19). 
Examination of the type species of Spintharosoma Zimmermann, 
Chrysis chrysonota Dahlbom, from the Ethiopian Region reveals 
that the American species previously placed in this genus are not 
congeneric.In S. chrysonota the tongue is long, the propodeal teeth 
clublike (fig. 15), paramere simple and rounded and cuspis slender 
and tapering (fig. 21), the male F-I is less than one third as long as F- 
II, and the mesopleuron divided into two parts by a deep transverse 
groove. American species also differ from Spintharina (generotype 
Chrysis vagans Radovskowsky). Spintharina has two large teeth on 
the mesopleuron, lobate propodeal teeth (fig. 16), and male genitalia 
with simple unlobate paramere and long slender digitus and cuspis 
(fig. 20). 
Gaullea Buysson 
The genus Gaullea is an obscure and poorly known genus. Gaullea 
was originally described from a single female, collected in Chaco, 
Santiago del Estero, Argentina. We have seen an additional 2 females 
and 3 males from Santiago del Estero, Argentina, plus the type. This 
genus is characterized by the very short RS stub, lack of a discoidal 
cell in the forewing and denticulate rim of T-III (figs. 6, 10). 
Linsenmaier (1959) placed Gaullea near Euchroeus. However, after 
close examination of the wing venation we have placed Gaullea near 
Argochrysis, because a crease in the wing indicates that the marginal 
cell would be closed if the RS stub were extended. The closed 
marginal cell is characteristic of Chrysis and its relatives. The 
expanded and bladelike metanotum and denticulate rim of T-III 
suggests that Gaullea is closely related to Argochrysis. The male 
genitalia of Gaullea is similar to that of Chrysis, with a simple though 
somewhat apically lobate paramere, broad foliaceous digitus and 
slender setose cuspis (fig. 23). 
Biology 
Host records for the neotropical Chrysididae are incomplete at 
best and nonexistant for Nesogyne, Cleptidea, Amisega, Pseudo- 
spinolia and Gaullea. The Amiseginae are typically phasmatid egg 
parasites. The remaining genera are wasp and bee parasites (table 1).
