REVISION OF PEORIINAE AND ANERASTIINAE 9 



bursae moderately short. Bursa well developed, rarely armed. Ductus 

 seminalis from or near posterior end of bursa. 



Key to Genera of Peoriinae Based Upon the Male Genitalia 



Within the Peoriinae intrageneric variation of alar, palpal, and 

 antennal features seriously limits their usefulness in separating genera. 

 In the absence of other distinguishing features, keys to genera must 

 rely on characters of the male genitalia. Whenever slide preparation is 

 impractical, reasonably certain determinations can often be made by 

 comparing external features of the specimens to descriptions and 

 photographs of adults. Genitalia slides should be prepared if correct 

 identification is critical. It is suggested that the indicated figures be 

 consulted when using the keys. 



1. Each spicate process (of uncus) basally branched into two long perpendicular 



tapering spines of nearly equal length; spicate processes connected by medial 



bandlike process (fig. 51) 2 



Spicate processes unbranched, or one branch at least twice length of other; 

 medial process absent or not bandlike 3 



2. Medial process of uncus bearing prominent posteromedial protuberance; juxta 



with pair of setaceous tubercles (fig. 118) Anacostia 



INIedial process of uncus unarmed, or with minute cusps only; juxta without 

 pair of setaceous tubercles (figs. 105-117) Peoria 



3. Spicate processes unbranched, blunt, elbowed in middle; gnathos tapering to 



single sharp apical spine (fig. 126) Atascosa 



Spicate processes various, not angled; gnathos with medial process not a single 

 sharp spine 4 



4. Each spicate process with rhomboidal lateral pad; juxta elliptical; aedeagus 



strongly tapered (fig. 131) Goya 



Rhomboidal pad absent; juxta rectangular or shield shaped; aedeagus not 

 strongly tapered 5 



5. Each spicate process a reciu-ved stout hook shorter than gnathos arm, tapering 



to sharp point; gnathos apically tricuspidate (fig. 130) Reynosa 



Spicate processes not as above, at least as long as gnathos arm; gnathos not 

 apically tricuspidate 6 



6. Apical process of gnathos digitate; spicate processes each with long lateral and 



much shorter caudal branches (figs. 119-125) Arivaca 



Gnathos without digitate apical process; spicate processes unbranched (figs. 

 127-129) Homosassa
