Full-grown larva. Length 1 1 .0—12.5 mm. Head (Figure 702, A) oblong, 

 ratio of length to width 1.4. Main color of head light yellow; pattern distinct, 

 dark brown, consisting of stripes and spots. Frontoclypeus long, narrow, 

 frontal sutures slightly concave near tentorial pit; coronal suture short; 

 gula narrow, triangular (Figure 702, B), pointed posteriorly. Pattern distinct, 

 bright. Anterior part of frontoclypeus with 3 pairs of large dots, those of 

 middle pairs more widely separated; a large, dark spot near tentorial pits; 

 posterior part with a transverse row of large dark dots; a narrow dark 

 stripe along frontal sutures. Dorsal stripes with large, dark dots; small 

 dots along coronal suture; lateral stripes replaced by longitudinal rows of 

 dots; ventral side with large lateral groups of large dots posteriorly. 



Labrum (Figure 703, A) wide, short, with a brown speck in median 

 depression; setae 1 and 2 represented by large, light spines and pressed to 

 anterior margin; seta 4 in form of a short, straight, light spine; setae 3, 5, 

 and 6 situated laterally in anterior part. 



Mandibles (Figure 703, B, C) with blunt, distal tooth; left mandible with 

 one tooth on ventral and 2 teeth on dorsal blade; right mandible with a small 

 blunt tooth on ventral blade, dorsal blade without teeth; 2 lateral setae of 

 different length (Figure 703, B,C). 



Submentum (Figure 703, D) represented by a slightly dark, tub erculate area; 

 setae large, light, situated laterally at anterior margin. Bothsetae of stipes 

 thin, of about equal length. Palpifer wide, large; distal seta reaching middle 

 of palp; median basal seta small; maxillary palp short, wide basally, 

 middle segment longer than other 2, terminal segment thin, with light
