A NEW BRAZILIAN MOTH OF THE GENUS GONIOTERMA 



WITH NOTES ON RELATED SPECIES 



(LEPIDOPTERA: STENOMIDAE) 



By W. Donald Duckworth 



This description is published to provide a name for a new species 

 of Microlepidoptera for which Dr. Laiiro P. Travassos F. of Sao Paulo, 

 Brazil, has ecological data to be published. 



During the course of the present study I found that the new species 

 is related very closely to several that have been associated improperly 

 with the genus Sienoma Zeller. These species have been studied, 

 features critical to their recognition have been discussed and figured, 

 and the species have been placed in their proper position in the genus 

 Gonioterma Walsingham. 



When fresh, the species examined are rather distinct in coloration, 

 but because they fade rapidly, specific recognition on the basis of 

 color alone is difficult. For this reason the genitalia are described and
