Key to Adult Females — Continued 



13. Elongate and slender, 2.25-2.85 mm. long and 0.45 wide; with 



median dorsal 8-shaped pores; anal tube fairly large, rather 

 long; anal opening ventral — elongatum, new species, p. 81. 

 Not elongate and slender, approximately 0.95 mm. in diameter; 

 without dorsal 8-shaped pores; anal tnbe small, bulbous; 

 anal opening apical proboscidis, new species, p. 157. 



14. (7) With setae on anal ring or on margin of anal opening well 



defined, 7-28 fx long, at least as long as a posterior marginal 



8-shaped pore 15 



Setae absent from anal ring and margin of anal opening, or, if 

 present, then minute or small, not more than 5 ix long and 

 shorter than a posterior marginal 8-shaped pore 20 



15. Apical setae around 22 /x long ; anal ring setae either about 9 



or 16-24 ix long 16 



Apical setae 36-56 \x long; anal ring setae 16-28 fx long 18 



16. Multilocular pores absent ; anal ring setae 8-9 fi long 



urichi Cockerell, p. 215. 

 Multilocular pores present ; anal ring setae 16-24 /x long 17 



17. Dorsal 8-shaped pores usually numerous along median line; 



marginal trilccular pores in a complete row. usually termi- 

 nating near the posterior marginal 8-shaped pores 



palmae Cockerell, p. 146. 



Dorsal 8-shaped pores sparse : marginal trilocular pores starting 



slightly anterior to anterior spiraeular pore bands and 



ending about halfway between posterior spiraeular pore 



bands and the posterior marginal 8-shaped pores 



oraniae, new species, p. 143. 



18. (15) Anal ring setae about 16 /x long; apical setae 36-44 m long; 



interapical setae about 2.7 /x long; dorsal 8-shaped pores 



absent pinangae, new species, p. 156. 



Anal ring setae 20-28 /x long : apical setae 46-56 /x long ; inter- 

 apical setae about 10 ix long ; dorsal 8-shaped pores absent 

 or present 19 



19. With dorsal 8-shaped pores, with marginal trilocular pores, and 



with approximately 22 multilocular pores 



boli viae, new species, p. 52. 

 Without dorsal 8-shaped pores, with marginal quinquelocular 

 pores, and without multilocular pores 



petrophilae (Fuller), p. 153. 



20. (14) Marginal row of 8-shaped pores rather poorly defined: dorsum 



with numerous, scattered 8-shaped pores, the majority 

 measuring 18-20 /x long and 14 wide ; mounted insect 

 slightly longer than wide, approximately 15 mm. wide; 



tubular ducts 48 ix long brevispinum Brain, p. 56. 



Marginal row of 8-shaped pores well defined: dorsum with or 

 without numerous, scattered 8-shaped pores, but if any 

 pores approximate the above in siz?. then the mounted in- 

 sects are conspicuously longer than wide, and are ap- 

 proximately 0.5 mm. wide; tubular ducts not more than 

 40 ix long 21 



21. Marginal 8-shaped pores with a sclerotized projection on dorsal 



edge ; certain species on Fagaceae from Asia 22 



Marginal 8-shaped pores without such a sclerotized projection— 2S 



22. Dorsal 8-shai>ed pores distributed over much of surface, not 



arranged in groups; atrium of spiracle slightly enlarged 

 and containing 2-4 quinquelocular pores : 9 or 10 quinque- 

 locular pores in each spiraeular band: margin of anal 

 opening with 2 minute setae__ adjunction, new species, p. 39. 

 Dorsal 8-shaped pores not distributed over surface, arranged 

 in groups when present: atrium of spiracle neither en- 

 larged nor containing pores; usually with less than 9 or 

 more than 10 quinquelocular pores in each spiraeular band: 

 margin of anal opening normally without setae (rarely 

 with 1 minute seta) 23
