Male genitalia. — Uncus present, simple, greatly elongate in 

 some genera, although reduced and indistinct in most American 

 species. Tegumen moderately to well developed. Gnathos usually pres- 

 ent, typically widely separated into a pair of digitate arms frequently 

 bearing a dense patch of stout setae near apex. Socii absent. Sub- 

 scaphium usually absent, present in Atoposea. Transtilla usually 

 present and weak, often with a pair of small, digitate processes arising 

 near juncture of valvae, transtilla well developed in some genera, 

 with median portion thickened and strongly arched. Vinculum often 

 weak, forming a narrow^ V-shaped ring articulating with bases of 

 valvae; sometimes more developed and massive (as in Bondia), with 

 apex extended into a short but prominent saccus. Valvae of various 

 form, often elongate and relatively broad to apex, sometimes more 

 reduced and stocky; a clavate or clawlike ampulla present in several 

 genera, completely absent in others. Juxta usually present, either 

 peltate or furcate. Aedeagus usually slender and rodlike, sometimes 

 throughout its length, but often with apical half expanded and 

 armed with dense rows or clusters of stout cornuti; ejaculatory duct 

 usually connected to aedeagus near middle at base of expanded 

 apical portion. Spermatophore elongate, apical end either inflated 

 or similar to rest of shaft in diameter; escape aperature for sperm 

 either at apical end or midway along shaft; length of spermatophore 

 often exceeding that of entire bursa copulatrix. 



Female genitalia — Ovipositor moderately long, telescoping; anal 

 papillae unmodified, soft and hairy; posterior apophyses elongate, 

 usually about 1.5-2.5 X the length of anterior pair; anterior apophyses 

 arising from area lateral to sterigma. Lamella antevaginalis usually 

 prominent, broad; posterior margin variously sculptured. Lamella 

 postvaginalis usually indistinct, unmodified. Caudal fourth or third 

 of ductus bursae strongly dilated to form a large, thick walled cavity 

 (antrum); walls frequently heavily papillose or reticulate; remainder 

 of ductus either completely membranous or with broad, thickened 

 bands extending full length to corpus. Corpus bursae either abruptly 

 swollen and distinctly set off from ductus or tubular and indistinct; 

 signa either absent or present as a pair of strongly furcate structures; 

 arms of signa usually slightly curved and serrated along inner edge, 

 smooth on outer edge. 



Key to the American Genera of Carposinidae 



la. Hindwings with veins. 3 and 4 connate or nearly so; if stalked then fused 

 portion never exceeding one-sixth the total length of 3. Male with gnathos 

 divided into a pair of elongate, usually setose arms (figs. 59-63). Female 

 typically with a pair of furcate signa (absent in Carposina dominicae and 

 Carposina species no. 1.
