Chitnarru ortiziana, new species 



Figures 13-16 



The relationship of this species to C. duckworthi, new species, is 

 shown most clearly by the structure of the aedeagus and the elongate 

 mesal lobe of the tenth tergum. It is distinguished by the narrowed 

 and flared tips of the lateral lobes of the tenth tergum and the broader 

 base of the clasper. 



Adult. Length of forewing 4-5 mm. Color fuscous, bases of legs 

 somewhat paler. Male genitalia: Ninth segment rounded anteriorly, 

 mesoventral process about as long as broad. Tenth tergum with a 

 pair of elongate semimembranous mesal processes; lateral lobe broad 

 at base, sharply constricted subapically, tip developed into a dorso- 

 lateral point. Clasper developed apically into a mesodorsally di- 

 rected lobe, broad and scooplike ventrally. Aedeagus slightly angu- 

 late, with an apico ventral spine; internally with a scabrous sac with a 

 darkened globose base, two spines of equal length, and a ring and rod.

Chimarra antigiia, new species 



Figures 17, 18 



Closely related to C. setosa Ross, this species differs from it in pos- 

 sessing a dorsoapical process on the tenth tergite and a broader dorso- 

 mesal shelf on the clasper. 



Adult. Length of forewing 4-5 mm. Color totally fuscous. Male 

 genitalia: Ninth segment with a narrow posteroventral keel. Tenth 

 tergite broad, with dorsoapical angle developed into a strong hook 

 that bears the sensillae. Clasper rounded in lateral view, dorsal mar- 

 gin developed into a broad, shelflike mesal process, and a slight ridge 

 subapically also on mesal face. Aedeagus simple, with two spines, 

 one of which is about two-thirds length of other.
