Selenarctia flavidorsata sp. n. 



(PL 20, figs 122, 123; PL 21, figs 124-126) 



[Automolis pseudelissa Dognin sensu auct. Misidentification.] 



(J. Apical segment of palp black; second segment black, with few pale yellow scales on front 

 surface; basal segment black dorsally, deep orange ventrally. Head deep orange; front with 

 black medial marking in few specimens (not type) ; vertex with small, black, medial spot at 

 posterior margin in few specimens (not type). Scape of antenna deep orange, remainder 

 black. Patagia, tegulae and rest of dorsal surface of thorax pale yellow (2 A3). Ventral 

 surface of thorax mostly dark brown (nearly black) except for deep orange near head and 

 pale yellow near wing bases. Forecoxa deep orange, rest of leg dark brown. Midleg dark 

 brown except for orange lateral patch on trochanter and pale yellow line along lateral (outer) 

 surface of femur. Hindleg dark brown. Forewing pale yellow (2A3) ; hindwing slightly 

 paler, its outer margin concave. Dorsal surface of abdominal segments 1 and 2 dark brown, 

 nearly black (with weak, dark blue iridescence) ; segment 3 dark brown with narrow band of 

 orange laterally; 4 as 3 but orange lateral area broader; 5-8 orange; 3-8 with lateral dark 

 brown patch on each side; 6-8 with dark brown, medial patches (5 similarly marked in some 

 specimens - not type) ; ventral surface orange, with some pale yellow hair-scales posteriorly on 8. 



$. As male but outer margin of hind wing convex, straight or weakly concave, and last 

 (7th) segment of abdomen dark brown and weakly iridescent dark blue dorsally except for 

 orange posterior fringe. 



Forewing length: holotype $ 24-5 mm; <J 22-5-25-5 mm; 0- 27-0-29-5 mm. 



^ genitalia. Valve curved inwards towards medial line; length of apical part of uncus 

 less than twice breadth ; spinose apical process of uncus arcuate, not extending beyond lateral 

 edge of aedeagus. 



9 genitalia. Signa small ; lamella postvaginalis weakly emarginate medially. 



This species is externally most like pseudelissa from which it differs in the absence 

 of a dark brown, medial marking on the dorsal surface of the thorax, the presence 

 of only one row of lateral abdominal spots, and by the slightly paler yellow colora- 

 tion. The $ genitalia most closely resemble those of elissoides, but the valves 

 are distinctly arcuate (viewed ventrally), the uncus broader apically, and the 

 apical process of the aedeagus shorter. 



Known from Brazil and northern Peru.
