blunt denticles further basally; lower blade with 3 teeth, which are partly 

 serrated; 1 or 2 small denticles between the lateral tooth and the next tooth; 

 several denticles further basally; median brush situated near the base of 

 the depression, forming a tuft of light feathered chetoids. Large, distal 

 denticle of right mandible serrated at the margin; median depression of 

 right mandible marked only distally; upper blade with 2 teeth, lower blade 

 with 3 teeth; teeth partly serrated; basal tooth very small; a row of 8 or 

 9 microscopic light spinules at its base. Outer setae of mandibles situated 

 near the ventral margin, light, relatively long; basal seta almost straight, 

 second seta slightly curved. 



Sclerites of maxillolabium (Figure 659, B) whitish yellow or yellow, 

 darker in some places. Submentum broad, shorter than gula; anterior -angle 

 processes small, thin apically, dark brown; setae strong and dark. Cardo 

 with dark brown margin at the side of the gula; seta at base small, thin. 

 Stipes yellow, with a dark brown stripe; basal seta situated on a membrane 

 near the sclerite dark brown and strong; apical seta light, thin, situated 

 near the margin. Palpifer yellowish white, slightly darker on the outside 

 near the base of the palp; mediodistal seta strong, dark, slightly smaller 

 than seta of stipes; basomedian seta transparent, small and spinelike; galea 

 short. Mentum brown; ventral sclerites small; their setae small and light; 

 palps very small and adpressed to the ligula. 



Pronotum yellow; its posterior margin narrow, reddish brown; spot at 

 lateral margin large, blackish brown; ridge on posterolateral process 

 with a narrow, brownish stripe; a white, longitudinal stripe at the point of 

 fusion of the posterior-angle processes ventrally in the middle; this stripe 

 narrow anteriorly and broad posteriorly. Three large dots on the dorsal 

 :60 side along the suture, in about the middle; a curved row of dots and a large 

 dot anterior to them in the middle of each half; 4 dots present near the 

 anterior angle. Setae reddish brown or blackish. Anterior -angle seta 

 moderately long; a small, light seta near it. Anterior margin with 3 long 

 setae, median seta shorter, seta situated near the anterior -angle seta longer 

 than the others; a short, dark seta near the middle seta, 9—10 small thin 

 setae at the margin. A long, dark seta situated slightly anterior to the spot 

 near the lateral margin; a very small, thin seta anterior to it, close to the 

 anterior angle; a spot with 2 small, thin setae posteriorly. Surface of 

 sclerite with 2 large, dark setae which are as long as the anterior -margin 

 setae; 4 small setae near the base of the median seta; 2 setae near the 

 second seta; a short dark seta near the anterior -angle group of dots. 



Propleuron (Figure 662) yellow; pleural suture blackish brown; near 

 episternum with 3 large, indistinct dots near the suture; epimeron with a 

 thin, brown seta; seta of trochantin similar, situated near the boundary with 

 the episternum; both setules light, situated on a membrane. 



Mesothorax longer than metathorax; dorsum of segments with a delicate 

 white pattern of stripes and spots. Anterior-angle and medioanal setae of 

 dorsum dark, thin, relatively large; anterior-margin seta of mesonotum 

 shorter than angle seta, dark; seta of metanotum small and light brown; 

 secondary anterior -angle seta, intermediate and lateral surface setae small 

 and light. 



Pleural sclerites of both segments small, light yellow, much smaller than 

 propleuron, with a narrow, short, pleural suture; epimeron rounded 

 posteriorly; seta situated near the margin of the sclerite light; seta of 

 episternum similar.
