bent upward, dorsomesally with a pair of knobs, apically with a 

 single spine. 



Holotype, male: Mexico (Mexico), Las Cruces National Park, La 

 Marquesa, 3000 m elevation, July 5-9, 1965, Flint and Ortiz. 



Paratypes: Same data, 37 c? 1 and 3 9. 



Protoptila cristata, uew species 



Figure 7 



The species belongs to Mosely's group 2, and is perhaps closest 

 to P. liqua Mosely. It is distinguished by the lack of processes from 

 the eighth segment, the double teeth ventrally on the tenth tergite, 

 and other differences in all parts of the genitalia. 



Adult. Length of forewing 3 mm. Color in alcohol brown. Male 

 genitalia: Sixth sternum with a short apicomesal process. Eighth 

 sternum prolonged, tip bifid, bearing a tooth dorsally just basad of 

 cleft. Tenth tergite short, dorsally developed into a crestlike process, 

 ventrally produced into two teeth. Aedeagus with the typical 

 complex of basoventral processes, apex bearing a C-shaped spine 

 surmounting several smaller spines. 



Holotype, male: Mexico (Vera Cruz), Cuitlahuac, Aug. 10-12, 1964, 

 Spangler. 



Paratypes: Same data, 3 d\ 



Protoptila huasteca, new species 



Figure 8 



This species falls within Mosely's group 2 because there is no lateral 

 spine from the aedeagus. It differs from all other species in this 

 group by the shape of the eighth sternum and the aedeagus, especially 

 in its possession of two pairs of slender ventral rods. 



Adult. Length of forewing 3 mm. Color pale brown; forewing 

 with intermingled brown and golden hairs. Male genitalia: Eighth 

 tergum hoodlike with posterior margin heavily sclerotized; sternum 

 strongly sclerotized with a pointed process from lateral margin at 

 midlength, a ventrolateral tooth, and a deep V-shaped mesal excision. 

 Ninth sternum produced into a scooplike structure, united apically 

 with eighth sternum. Tenth tergite decurved laterally, apex devel- 

 oped into a sharp, mesally directed point. Aedeagus with a long 

 paired process lying within ninth sternum, tips directed mesally; 

 apex membranous with an internal spine; two pairs of slender processes 

 ventrally, basal process short, distal process very long with curving 

 apex. 



Holotype, male: Mexico (San Luis Potosi), 25 miles north of 

 Tamazunchale, Aug. 3-4, 1963, Duckworth and Davis.
