 Protoptila bicornuta, new species 



Figure 8,/ 



The structure of the apical half of the aedeagus is totally unlike 

 any other described species. Because there are no lateral spines on 

 the aedeagus, the species will fall in Mosely's group 2, but differs from 

 the other species in this group in the shape of the process of the 

 eighth sternum and in the structm-e of the aedeagus. 



Adult. — Length of forewdng 3 mm. Wings covered with browm 

 hair, and with an indication of an irrorate pattern of more golden hairs. 

 Sixth sternum with usual blunt apicomesal lobe. Male genitalia 

 (fig. 8,/): Almost entirely retracted within eighth segment; eighth 

 sternum produced into a long slender process, bifid for apical fourth; 

 ninth sternum produced into a shallow scoop, with an emarginate 

 apical margin; small ovoid cercus present near base of tenth tergite; 

 tenth tergum divided into lateral decurved lobes, apices divided into 

 internal and external points. Aedeagus complex: Base dorsally with 

 usual halberd-shaped mesal lobe; 2 short rods ventrally near base, 

 beyond these an obscure complex from which 2 hirsute lobes extend; 

 constricted to a very narrow neck below tenth tergum bej^ond which 

 3 structures arise, a pair of curving dorsal processes, a central tube 

 with membranous end bearing 2 short spines, and 2 strong ventral 

 hooks. 



Holotype cf: Hondm-as: Lancetilla, August, Stadelmann (MCZ 

 Type 30410).
