A REVIEW OF THE TAXONOMY AND MORPHOLOGY 
OF THE BEROTHIDAE, WITH THE DESCRIPTION OF 
A NEW SUBFAMILY FROM CHILE (NEUROPTERA) 
By Ellis G. MacLeod 1 and Phillip A. Adams 2 
Introduction 
Collections of Neuroptera which we have received from Chile 
contain a series of specimens of an unusual berothid representing an 
undescribed subfamily. Study of these specimens has convinced us 
that, in addition to throwing new light on the probable evolutionary 
relationships within the Berothidae, the new form makes somewhat 
easier an understanding of some of the structural peculiarities of 
the more-specialized species of this family. 
The description of the new subfamily has thus been combined 
with a reexamination of certain aspects of the morphology of bero- 
thids and a redefinition and generic synopsis of the subfamilies. These 
points will be considered in detail following the taxonomic descrip- 
tion of the new form. 
Cyrenoberotha, new genus 
Figures 9, 14-17 
Description. Head capsule and mouthparts, particularly palpi, 
elongate (figs. 1, 2, 3, 4) ; vertex moderately elevated, without raised 
tubercles; head not particularly inflated behind eyes; antenna monili- 
form, with short scape. Prothorax (fig. 1) somewhat more elongate 
and less robust than usual in this family. Prosternum small, quad- 
rangular. Legs slender, setose, without raptorial modifications. Ab- 
domen short, ninth tergite distinct from ectoproct in both sexes; 
callus cerci of ectoprocts present, with trichobothrial setae. 
Male (figs. 7, 8, 9) : 10th sternite not discernible beneath anus. 
Gonarcus arms disconnected medially, with 9th gonocoxites ( = 
“parameres” ) 3 articulated to ventral tips of arms, these latter

The reasons for the adoption of the terminology utilized here for the 
internal male genitalia have been briefly outlined by Adams (1967). A short 
discussion of the modified terminology which we have applied to the female 
terminalia of berothids is given on p. 247 of the present paper.
