1 . Ganonema extensum Martynov 



Levanidova, 1951: 533-537, Figures 14-21. 



Full-grown larva. Length 24.0— 24.5 mm. Head dark chestnut brown, 

 with light periocular spots; pattern on head with light oblong dots (Figure 

 662, a). Frontoclypeus differing from that of Ani s o c ent r op u s in its 

 shorter anterior and long posterior part, with 3 oblong light dots forming a 

 fan and a lateral, smaller dot on posterior part. Lateral anterior -margin 

 seta as inAnisocentropus, transparent, short, curved inward; 

 intermediate and median anterior-margin setae long, straight, black, the 

 latter smaller and thinner; anterior frontal seta short, dark; intermediate 

 frontal seta moderately long, situated near tentorial pit; posterior frontal 

 seta slightly smaller.- Dorsal stripes along sutures replaced by 

 characteristic, oblong dots forming a row lateral to frontal sutures, and 2 

 rows lateral to coronal suture: rows of light dots on site of lateral 

 stripes; similar large light dots on ventral side lateral to gular suture. 

 Gula triangular, slightly larger than in A. pallidus (Figure 6 62, b). 



Large dorsal setae brownish black, small setae lighter and much thinner. 

 Seta 9 long, seta 11 small, both situated on dark background near margin of 

 periocular spot; seta 7 moderately long, thinner than 9; seta 10 situated 

 before and lateral to eye, small, brown; seta 14 situated behind eye, the 

 largest on the head; seta 12 thinner and shorter; seta 13 short, thin; setae 

 15 and 16 long, situated close together one behind the other; seta 17 thin, 

 moderately long, as long as posterior frontal seta. On ventral side, in 

 contrast to A. pallidus, seta 8 small, yellowish; seta 1 8 larger, dark, 

 short. 



Labrum as inAnisocentropus, with light membranous margin and 

 dense, short, yellowish white hairs laterally; dorsal sclerite reddish brown, 

 with a transverse row of short, strong, blackish brown setae anteriorly, 12 

 setae on each side (Figure 663, A). 



Mandibles short, massive, black, with deep median indentation; distal 

 tooth blunt; both mandibles with a large trapezoidal process on dorsal 

 blade near distal tooth (Figure 663, B); ventral blade with 2 teeth on left 

 mandible, one tooth on right mandible; median indentation with a brush 

 consisting of 3 tufts of shining, brownish yellow hairs on both mandibles; 

 those of left mandible more dense; lateral setae situated basal, short, dark. 



Pregula brown. Sclerites of cardo transverse, reddish brown, blackish 

 laterally, on median side and at lateral margin, with 2 short setae laterally 

 near anterior margin. Other sclerites of maxillolabium brownish. 

 Submentum (Figure 662, B) with small oblong median sclerites; seta large, 

 brown, distal. Stipes large; both setae strong, dark brown, of about equal 

 length. Palpifer large, almost as long palp; distal seta small, brown; 

 median basal seta small; both setae situated on membrane; palp small, 

 conical, with short segments of about equal length. Mentum brown, dark 

 brown basally, large. Ventral sclerites in form of light dots; seta small, 

 white. Palpiger large, horseshoe -shaped, smoke brown, palp with a similar 

 sclerite; labial lobe conical. 



Prothorax (Figure 664, A) not oblong, in contrast to Anisocentropus; 

 pronotum wide, each half about as long as wide. Anterior margin and 

 anterior angles with narrow brown margin; posterior margin, posterior - 

 angle processes, and a short posterior part of lateral margin black; surface
