 dorsum of thorax and abdomen never with a median ridge or 

 with small spines on the segments, 

 c. C'remaster absent or never long and well developed ; furrows 

 usually present on the dorsum between the ninth and tenth

 appearance ; labrum in its normal position, 

 d. Caudal end of body with all the setae straight and very 

 short; cremaster short and blunt; lateral margins of the 

 dorsum of tenth abdominal segment with prominent deep 

 furrows extending caudad to the proximal end of the 

 cremaster; a large portion of the labial palpi often ex-

dd. Caudal end of body never with all the setae straight, but 

 usually long and hooked ; lateral margins of the tenth ab- 

 dominal segment never with deep furrows unless they are

 e. Dorsal furrow, if present between the ninth and tenth

 and there is some doubt as to whether they should be included with
