AND DESCRIPTION OF NEW SPECIES 
(CHRYSIDIDAE, HYMENOPTERA)*

The subgenera of Neochrysis comprise 4 distinct groups of species 
in the Chrysidinae (Chrysididae), which were discussed by Kimsey 
and Bohart (1980). Subsequent reevaluation of these subgenera 
indicates that they have sufficiently discrete diagnostic characteris- 
tics to justify their elevation to genera. Ipsiura is the most divergent 
group and is being elevated by Bohart (1985). 
The relationships of these groups to other genera of Chrysidinae 
are obscure. Although they have been placed in the Euchroeini, 
based on the widely open marginal cell and long radial sector (Kim- 
sey 1983), no sister group within this tribe is yet apparent and 
further study is necessary. However, these 4 taxa are closely related 
to each other, based on the characteristics given in table I, particu- 
larly those of the apical external sterna, RS vein and hindfemoral 
pit. 
A number of abbreviations have been used, some of which are 
illustrated in fig. 1: T = gastral tergum, S = gastral sternum, F = 
flagellomere, MOD = midocellus diameter, LID = least interocular 
diameter. 
In each list of included species an asterisk indicates that the type 
has not been seen. 
Specimens have been borrowed from the following institutions:

Parana, Curitiba, Brazil; davis — Bohart Museum of Entomology, 
University of California at Davis; Manhattan — Department of 
Entomology, Kansas State University, Manhattan; new york —

tory, New York; tucuman — Instituto Miguel Lillo, Tucuman,
