seta darker and longer than anterior-margin setae; a second, shorter 

 anterior-angle seta lateral to this seta; 4 small light setae between them. 

 Anterior -margin setae forming two groups; the first group begins at a 

 distance from the median suture; it consists of 5 or 6 light, equally spaced 

 setae; the setae situated further medially longer than the lateral setae; 

 2 shorter widely separated setae between the median group and the anterior- 

 angle seta. The row of anterior -margin setae, which are directed slightly 

 upward and anteriorly, forms a fan-shaped collar above the head; this fan 

 resembles the group of anterior-margin setae of the pronotum of Cheuma- 

 topsyche lepida. Medioanal surface seta slightly shorter than anterior- 

 margin setae, situated near the median suture, on a light area in the anterior 

 quarter of the sclerite; a second long seta situated farther posteriorly; 

 a short dark seta with a light dot at the base near the anterior margin of the 

 lateral spot; the small surface seta posterior to the median seta situated 

 in about the middle of the sclerite.
