Barberia Dyar 



Barberia Dyar, 1905, p. 39. — Barnes and McDunnough, 1917, p. 149 — Hamp- 

 son, 1918, p. 131. — McDunnough, 1939, p. 36. [Type: Barberia affinitella 

 Dyar, 1905. Monobasic] 



Diagnosis. — The distinctive uncus, basally triangular and with a 

 narrow terminal portion, distinguishes the genus from all other New 

 World phycitines with similar wing venation. 



Description. — Frons oblique; labial palpi upturned, slender; 

 maxillary palpi well developed, reaching frons; tongue exposed between 

 palpi; antennae filiform, compressed; ocelli small, appearing as dark- 

 ened spots. 



Forewings with 9 veins; II2 from near upper outer angle of cell; 

 R3H-4 fused, separate from R2 at base; Mi from angle; M2+3 fused, 

 from lower outer angle; Cui from just before angle; Cuj from before 

 angle. Hindwing with 7 veins; Sc and Rs long stalked; Mi from upper 

 outer angle of cell; M2+3 fused, short stalked with Cui, from lower 

 outer angle; Cu2 from before the angle. 



Male genitalia with uncus triangular on basal two-thirds, distal 

 third narrow, distal half heavily setose dorsally and laterally. Gnathos 

 arms terminating in anterior ventral hook; medial process a flattened 

 posteriorly directed hook, cur^^ed dorsally at tip. Transtilla incomplete, 

 a pair of flat plates about 3^ times as long as wide. Juxta U-shaped, 

 arms sharp pointed. Vinculum truncate. Valvae with apex obliquely 

 rounded. Aedeagus straight, vesica unarmed. 



Female genitalia with ovipositor tip broadly rounded. Apophyses 

 straight, broadened basaUy; posterior parallel, anterior slightly longer, 

 diverging. Ductus bursa narrow, leaving bursa about one-fifth from 

 posterior end. Ductus seminalis from posterior end of bursa. Bursa 

 well developed; signum a long narrow sclerotized infolding about one- 

 fourth from anterior end of bursa. 



Discussion. — The male genitalia are quite similar to Heinrich's 

 illustration of Anderida, but males of Barberia differ in the truncate 

 vinculum and lack of hair tufts on the eighth abdominal segment. 

 The two genera are less similar with respect to female genitalia and 

 wing venation.
