Gonionota cristata Walsingham, 1912, in Godman and Salvin, Biologia Centrali- 

 Americana, vol. 42 (Lepidoptera-Heterocera, vol. 4), p. 129. 



The male genitalia of cristata have not been figured previously; 

 they are shown here for comparative reasons. 



Slide examined: cf, JFGC no. 3394. No female available. 



Male genitalia: Harpe rather abruptly narrowed in distal half; 

 cucullus truncate; clasper a very small curved ridge about middle of 

 harpe. Anellus subquadrate, deeply excavated on posterior edge. 

 Aedeagus very stout, bent slightly before middle; vesica armed with 

 two groups of strong cornuti, the four or five of the proximal and 

 smaller group short, dentiform, those of the distal group longer and 

 more numerous. Vmculum rather narrow, rounded. Gnathos a 

 narrowly oval spined knob. Uncus with long, slender, proximal stalk 

 and widely divergent, moderately slender distal arms.
