RECLASSIFICATION OF SPECIES FORMERLY IN AUTOMOLIS 



New genera 



VIVIENNEA gen. n. [Gender: feminine] 



[Automolis Hiibner sensu auct. Partim.] 



[Rhipha Walker sensu Travassos & Travassos, 1954 : 217. Partim.] 



Type-species: Automolis moma Schaus, 1905 : 218. 



cj. Palp extending to about middle of clypeo-frons ; apical segment of palp minute. Head 

 without processes. Antenna uniserate, each segment with numerous setae on ventral surface. 

 Patagia yellow, or mainly yellow. Tegulae yellow anteriorly. Midleg with pair of terminal 

 spurs; hindleg with terminal pair and subterminal pair of spurs. Forewing brown with yellow 

 or orange-yellow markings, or yellow with brown markings (salma and superba) ; venation as 

 in text-figure. Tymbal organ with between 50 and 60 microtymbals. Hindwing either 

 entirely yellow (some specimens of salma) or yellow proximally, and brown distally; folded 

 anal area contains scent-scales and hair-pencil on ventral side. Abdomen orange or yellow, 

 and dark brown; dorsal surface of at least terminal segment moderately strongly iridescent 

 dark brown and green or blue. 



o* genitalia. Eighth abdominal tergite with short apodemes; eighth sternite with vestigial 

 apodemes. Saccus small. Valves simple, apex acuminate, rounded or spatulate; heavily 

 sclerotized in moma, momyra, tegyra, gyrata, superba and salma; less heavily sclerotized in 

 flavicincta, dolens, ardesiaca and griseonitens. Uncus tapered posteriorly and spinose dorsally 

 in moma-group ; truncate apically in flavicincta-group with dorsal carina and two lateral carinae. 

 Aedeagus with spinose process at apex ; lobes of vesica variously scobinate. 



9- Similar to o* but hindwing relatively greater in area, its outer margin more strongly 

 convex, and anal area without recognizable scent-organ ; antennae filiform with pair of long 

 setae on ventral surface of proximal segments. 



$ genitalia. The posterior margin of 7th sternite straight or weakly concave, lamella post- 

 vaginalis emarginate medially. Ductus bursae short and broad ; sclerotized posteriorly. Corpus 

 bursae with two small circular signa; appendix bursae arising from right side of corpus bursae, 

 either posteriorly (species other than salma and superba) or anteriorly (salma and superba). 

 Ductus seminalis opening with appendix bursae near connection of latter with corpus bursae. 

 Anterior apophyses short; posterior apophyses longer than latter. Paired scent tubules short 

 in »woma-group, broader and much longer in flavicincta-group [these open onto the dorsal 

 surface of the abdomen at the base of each papilla anales]. 



Vivienna is probably most closely related to Ordishia, which it resembles in 

 several external and genitalic characters. It can be distinguished from Ordishia 

 by the following features: patagia yellow or mainly yellow; absence of longitudinal 

 bands on tegulae and of pale, mid-dorsal line on thorax; presence of proximal 

 (antemedial) yellow transverse band on forewing (or base of wing entirely yellow) ; 

 presence of folded anal scent area in male; dorsal surface of terminal (posterior) 

 segment of abdomen moderately strongly iridescent brown and blue or green; 

 uncus either tapered posteriorly or dilated with lateral carinae; aedeagus with
