NEOTROPICAL MICROLEPIDOPTERA — DUCKWORTH 107 



area of faint rose runs parallel to, and just below, costa; dorsum 

 narrowly reddish brown; indistinct fuscous spot on costa at middle, 

 from which indistinct, oblique fuscous line runs to anal angle; in- 

 distinct, outwardly curved, transverse fuscous line at apical four- 

 fifths; spot at end of cell a rather indistinct area of white surrounded 

 by fuscous scales; apical margin rich yellow; entire wing sprmkled 

 with fuscous scales; cilia rosy ochreous. Hindwing ochreous, anal 

 area shaded with gray; cilia rosy ochreous. 



Male genitalia (slide WDD 3061, type): Uncus bluntly pointed, 

 slightly recurved; gnathos long, finger-like; harpe short, broadest near 

 middle, bluntly pointed at apex; anellar lobes elongate triangular- 

 shaped, pointed at apex; aedeagus small, narrow, vesica armed with 

 two clusters of small cornuti at apex and single, large cornutus basally. 



Female genitalia (slide WDD 2799, paratype): Ductus bursae with 

 corrugated, pouchlike area just before ostium bursae; inception of 

 ductus seminalis near ostium. 



Type: Nova Teut6nia, Brazil, 3500 m. USNM 66687. 



Distribution: brazil: Nova Teutonia (Oct.). Surinam: Cottica 

 River, Moengo (May). 



Described from male holotype, Oct. 21, 1948 (Fritz Plaumann), 

 Nova Teutonia, Brazil, 3500 m.; one male paratype, 1.20 (Parish), 

 Tefe, Brazil; and one female paratype, Oct. 21, 1948 (Fritz Plaumann), 

 Nova Teutonia, BrazU, 3500 m. 



This species is distinguished readily by the two apical clusters of 

 small cornuti and a single, large basal cornutus in the aedeagus of the 

 male genitalia and by the ductus bursae of the female genitalia with 

 a corrugated, pouchlike area near the ostium bursae.

Alar expanse 19 mm. 



Antenna brownish. Head, palpus, and thorax deep ochreous shaded 

 with rose. Forewing yellow ochreous, fuscous triangular spot at 

 middle of costa; spot at end of cell small, fuscous; faint fuscous line 

 from costal spot to dorsum; outwardly curved, transverse fuscous 

 line from apical third of costa to near tornus; cilia whitish ochreous 

 shaded with rose. Hindwings whitish ochreous, apex and termen 

 faintly yellowish; cUia whitish ochreous. 



Male genitalia (slide WDD 2817) : Uncus pointed, sharply recurved; 

 gnathos short, broad; harpe short, broad, rounded at apex; anellar
