Antenna reddish brown basally, brown beyond. Head reddish 

 brown, hghter between eyes; second segment of labial palpus whitish 

 on inner side, brown on outer side, apical segment whitish. Legs 

 whitish, shaded with brown. Thorax rosy ochreous dorsally, with 

 central, posterior ridge of raised reddish brown scales. Forewings 

 rosy ochreous with costa narrowly brick red; fuscous, nearly straight 

 line extending from middle of costa to basal angle of dorsum; at 

 apical fourth a transverse, outwardly curved fuscous line extending 

 from costa to dorsum ; at end of cell a circle of fuscous scales enclosing 

 brown area slightly lighter than rest of wing; entire wing sprinkled 

 with occasional fuscous scales; cilia rosy brown. Hindwing whitish 

 ochreous with cilia slightly shaded with rose at apex. 



Male genitalia (slide WDD 2095, type) : Uncus bluntly pointed 

 apically, slightly recurved; gnathos slightly flattened dorsoventrally ; 

 harpe bluntly pointed at apex; anellar lobes symmetrical, broad 

 basally, tapering to slightly recurved, acute apex, and with medial 

 edges serrate beyond apical third; aedeagus broad basally, narrower 

 apically, vesica armed with several large, heavily sclerotized cornuti. 



Female genitalia (slide WDD 3056) : Ductus bursae with patch of 

 small spines near inception of ductus seminalis; inception of ductus 

 seminalis near corpus bursae. 



Type: In the United States National Museum. 



Type locality: Paraiso, Canal Zone, Panama (S. hovinella); Taboga 

 Island, Panama, 200-1000 ft. {S. curiata). 



Distribution : Panama : Paraiso, Canal Zone (June) ; Corozal, Canal 

 Zone (June, July); Taboga Island, 200-1000 ft. (Sept.). 



Mejrrick described S. curiata from a series of females and Busck 

 described S. hovinella from a series of males; however, examination 

 of the types reveals both species identical in color and maculation 

 and unquestionably the same species. The failure of past workers 

 to accompany descriptions of new species with illustrations has 

 resulted undoubtably in many synonyms of this type in the family 

 Stenomidae. 



The serrate anellar lobes in the male genitalia and the patch of 

 small spines near the inception of the ductus seminalis in the female 

 genitalia serve to distinguish L. hovinella from the other species of 

 Leihata.
