NO. 3585 MICROLEPIDOPTERA, XII — DUCKWORTH 13 



at base with two pointed apical lobes, anterior lobe much longer 

 than posterior; aedeagus with a strong laterally curved, dorsal process 

 at apical two-thirds, ventrally hooked process at apex, vesica -without 

 cornuti. 



Female genitalia: Unknown. 



Type: In the Zoologisches Museum der Humboldt-Universitiit zu 

 Berlin. 



Type-locality: Brazil. 



Distribution : Known only from the type-locality. 



This is one of the two species for which a distribution map was not 

 prepared. The species is known only from the type specimen, for 

 which the only locality given is Brazil. This obviously is insufficient 

 for mapping purposes and further information must be acquired before 

 a map is prepared. 



The strong, ventrally hooked apical process and laterally curved 

 dorsal process at apical two-thirds on the aedeagus in the male 

 genitalia readily separates L. myopina from other species in the genus. 



Letfiata dispersa, new species 



Plate 2 (fig. 2); Figures 13, 14; Map 6 



Alar expanse 23 mm. 



Antenna, head, labial palpus stramineous. Legs stramineous 

 lightly shaded with brown. Thorax and tegula yellow. Forewing 

 yellow with costa rosy; dorsum narrowly edged brown; faint spot in 

 fold bro\Mi; spot at end of cell consisting of ring of brown enclosing 

 whitish spot; oblique brown line extending from costa at near midpoint 

 through spot at end of cell to tornus; terminal line brown; cilia brown 

 basally, whitish beyond. Hindwing gray; cilia whitish. 



Male genitalia (slide WDD 3308, type) : Uncus short, recurved ; 

 gnathos short, broad; harpe short, broad, articulating with upper 

 edge of anellar lobe ; anellar lobes symmetrical, broad at base narromng 

 sharply at midpoint, apical half falciform; aedeagus broad, with acute 

 apical projection bearing one laterally directed spine, vesica armed 

 with numerous spiculate cornuti. 



Female genitalia: Unknown. 



Type: In the collection of the U.S. National Museum, no. 690S6. 



Type-locality: Chapada, Matto Grosso, Brazil. 



Distribution : Known only from the type-locality. 



Described from the male holotype: "Chapada, near Cuyabd, 

 Matto Grosso, Brazil (H. H. Smith)." 



This species is very closely related to L. angusta; however, the form 

 of the anellar lobes and the large, laterally directed spine on the 

 apical process of the aedeagus in the male genitalia serve to distinguish 

 L. dispersa.
