NO. 3535 MICROLEPIDOPTERA, IX — OBRAZTSOV 589 



Male genitalia. — Uncus with a narrow stalk ending with a 

 rotundate, flatly calathiform-dilated apex with an acute point directed 

 ventrad and accompanied by a little, haired papilla. Valva sub- 

 rectangular with external margin rotundate; sacculus slightly dilated 

 at base, and narrowly prolonged along ventral margin (of a folded) 

 valva. Aedeagus rather slender with a slightly curved apical process; 

 cornutus with two basal branches and a small, conical cap on apex; 

 cuneus indiscernible. 



Female genitalia. — Sinus vaginalis with a trapezoidal lamella 

 antevaginahs. Antrum short, tubular with two shghtly arcuate 

 colliculi remote one from another. Cervical portion of corpus bursae 

 with fine, longitudinal striation and a stronger sclerotized, oblique 

 striation probably representing a modified cestum; corpus bursae long 

 and narrow; signum ovate. 



Types.— Holo type, USNM 67566, male (genitaHa on shde 2-Obr., 

 Jan. 22, 1961), Loja vicinity, Loja, Ecuador, 1S87 (Dognin Collection), 

 allotype, USNM, female (genitalia on shde 4429, JFGC), El Monje 

 near Loja, Loja, Ecuador, 1893 (Dognin Collection). 



Remarks. — Very similar to shafferi, new species, but differs from 

 it in the shapes of the terminal marldngs and the subterminal spot 

 of the forewing. Also the apical spot and the terminal spots of the 

 hindwing are of different shapes and in dognini much larger. The 

 female genitalia of both species differ in the shapes of the lamella 

 antevaginahs, colhculi, striation of the cervix bursae, and the signum. 



Besides the types of dognini, there is in the U.S. National Museum 

 a female specimen from Loja vicinity, Ecuador (pi. 1, fig. 7), somewhat 

 resembling this species, and differing from it in the details of the wing 

 marldngs. The costal streaks of the forewing of this specimen are 

 distinctly less oblique than in dognini, the penultimate and the last 

 of them are simple, and two separate spots are located internobasad 

 of these streaks and the streak preceding the penultimate one. Also 

 the apical spot of the hindwing is replaced by a group of three separate 

 spots. It is quite possible that this specimen might be a variety of 

 dognini, but this cannot be proven presently because the abdomen of 

 the moth is missing.
