NEW SPECIES OF CONIOPTERYGIDAE (NEUROPTERA) 
FROM NORTH AMERICA 1 
By Victor Johnson 2 
Introduction 
Six new species of Coniopterygidae are herein described from 
North America. The descriptions are based primarily on male 
genitalia, but other characters are given where they appeared to be 
diagnostic. Specimens in this study were collected by the author 
(Coniopteryx delta and Semidalis tricornis) or borrowed from the 
following collections: Arizona State University (ARIZ), Illinois 
Natural History Survey (INHS), Pennsylvania State University 
(PSU) and Utah State University (UTAH). All specimens were 
examined in glycerine with a dissection microscope and drawings 
were made freehand with a counting grid in one ocular.
