1. Apatania wallengreni McLachlan 



Lepneva, 1928:81-83, Plate II, Figures 1-4. 



Full-grown larva. Length 7—8 mm. Sclerites of head (Figure 182, A) 

 brown, covered with small spinules; area near occipital foramen broadly 

 light brown, smooth, without spinules. Eyes on large light area; antennae 

 closer to anterior margin than to eye. Frontoclypeus slightly dark near 

 anterior margin and posteriorly near sutures; tentorial pits dark brown; 

 spinules on frontoclypeus thin, sharp, dense in the anterior part laterally, 

 sparse elsewhere. Surface slightly dark laterally to posterior branch of 

 frontal sutures and before eye; spinules lateral to frontal sutures, dense, 

 needle-shaped; surface behind eye and ventrally slightly tuberculate, with 

 a reticulate pattern; middle of ventral surface slightly dark, lighter posterior 

 area with brownish punctation; lateral to gular suture spinules single, 

 thin, needle-shaped; tuberculate reticulate area with minute spinules which 

 may be blunt or sharp, arranged in rows, or singly on crests. Gula brownish, 

 oblong (Figure 182, B), almost twice as long as wide, with blunt posterior 

 end; spinules sparse, small, needle-shaped; pregula orange-brown, like 

 the anterior margin of the head. 



Most setae thick, pinkish brown; median and intermediate, anterior- 

 margin setae moderately long, latter seta slightly longer, lateral seta 

 light, thick basally, filiform apically; anterior-frontal seta also light but 

 shorter, middle seta small, thin, situated near tentorial pit, posterior seta 

 moderately long, brownish basally and thick, filiform apically; small 

 secondary setae light, thick, larger, short and moderately long, pinkish brown, 

 situated mainly in the anterior angle. 



Seta 7 situated anterior to antenna, moderately long; seta 9 long; seta 14 

 slightly longer, less thick; seta 15 situated posteriorly nearby, thinner, long 

 but slightly shorter than 14; other setae much smaller, brownish, or light; 

 seta 11 situated near posterior margin of eye close to margin of light area, 

 short; seta 10 situated anterior to eye, slightly smaller; seta 12 situated 

 laterally behind eye, thin, short; seta 13 situated nearby, small; seta 16 

 situated behind 15, light; seta 17 situated near suture anterior to the fork, 

 short, smaller than the posterior frontal seta; ventral seta 8 small, brown, 

 thick; seta 18 smaller, light. Secondary setae arranged longitudinally 

 from the antennae, laterally along the frontal sutures, short and small, 

 brownish and light. 



Dorsal sclerite of labrum brownish; posterior -margin stripe and base 

 of posterior-angle sclerites orange -brown; seta 1 small; setae 2 and 3 

 large, light, thick, slightly smaller than the brown setae 5 and 6; seta 3 

 situated at the margin, yellowish, or slightly posterior to 5; setae 3, 5, and 

 6 with long, filiform end. 



Pronotum (Figure 183) mainly light brownish, whitish near anterior 

 margin and laterally; anterior margin yellowish, lateral margin reddish 

 brown, blackish at the base near black posterior-angle spot; surface and 

 posterior-margin area with large, indistinct, pale brownish dots; spinules 

 minute, pointed, in rows, rarely singly, situated on surface or on small 

 ridges which in some places lack spinules or are indistinctly serrated; 

 in contrast to Baicalinini, anterior-margin spinules very small but larger 

 than surface spinules; posterior margin yellowish, separated by a light
