The two largest chrysidid genera in the neotropics are Trichrysis 
and Neochrysis, whose dominance roughly corresponds to Cerato- 
chrysis and Chrysis in the nearctic fauna. Detailed examination of 
Trichrysis in both hemispheres has revealed four distinct groups. Old 
World Trichrysis can be divided into two subgenera, based on 
whether the discoidal cell is complete ( Trichrysis s.s.) or incomplete 
(Chrysidea ). The New World Trichrysis can also be divided into two 
groups based on the same characteristic. However, New World 
Trichrysis are different from the Old World forms since they have a 
distinct and almost articulated telomere on the male genital capsule 
(fig. 24). This discrete telomere has not been found in Old World 
Trichrysis (fig. 22). 
We therefore propose the establishment of two new subgenera in 
the genus Trichrysis. An asterisk after a species name indicates that 
we have not seen the type. 
Trichrysis Lichtenstein 
Trichrysis (Caenochrysis) Kimsey and Bohart, new subgenus 
(derivation: Kaeno = new, Gr.) 
Subgenerotype: Chrysis tridens Lepeletier 
Included species: amazonica Mocsary, azteca Mocsary, brasiliana 
Guerin, carinata Say*, divergens Cresson, gibbosa Mocsary, 
mathani Ducke*, mucronata Brulle*, nigropolita Bischoff, par- 
vula Fabricius, taschenbergi Mocsary, triangulifera Mocsary, and 
tridens Lepeletier*. 
Discussion: Members of the subgenus can be recognized by the 
sometimes thin but completely sclerotized outer veins of the discoidal 
cell in the forewing (fig. 18), and the presence of a telomere on the 
paramere (fig. 24). 
Trichrysis (Lorochrysis) Kimsey and Bohart, new subgenus (deriv¬ 
ation: Loron = strap, Gr.) 
Subgenerotype: Chrysis doriae Gribodo ' 
Included species: areolata Mocsary, armata Mocsary, boscii Buys- 
son, crotonis Buysson, doriae Gribodo, puberula Spinola, quadri- 
rimosa Mocsary, saussurei Mocsary. 
Discussion: This subgenus is distinguished by a faint or incompletely 
sclerotized discoidal cell in the forewing, with at least the anterior 
vein faint or lacking (fig. 17) and the presence of a telomere on the 
paramere. In general the species are smaller than those of Caeno¬ 
chrysis.
