Sclerites of cardo light brown, with black median margin; lateral seta 

 very small, median seta relatively large. Submentum wider anteriorly; 

 lateral setae thin, moderately long. Stipes yellowish; lateral seta shorter 

 but thicker than setae of submentum. Palpifer narrower at median margin; 



365 distal seta situated on membrane, relatively large, brownish; median seta 

 light, spine-shaped, very small, situated on sclerite. Maxillary palps blunt, 

 short, 1st segment slightly larger than following segments, with a semi- 

 circular sclerite; other segments with circular sclerites. Galea short, 

 wide, its 2 basal setae larger than others. Mentum in form of uniformly 

 wide semicircle; ventral rods narrow, with a small seta. Palpiger relatively 

 large. Labial palps small, labial lobe short, wide, covered with hairs. 



Pronotum (Figure 619) brown or dark brown anteriorly, light brown 

 posteriorly, with indistinct, light, oblong dots; posterior margin wide, mainly 

 reddish brown, separated by a groove, which is black in middle; posterior 

 margin with 2 black spots; numerous black setae (84— 90> according to 

 Nielsen) near anterior margin and in anterior half, including anterior angles, 

 those at anterior margin % as long as width of head; small, thin spinules 

 at anterior margin and angle. 



Mesonotum (Figure 619) light brown anteriorly, with lighter dots at lateral 

 margin; posterior part yellowish, with dark dots; anterior part and anterior 

 angle with 56—57 setae, including primary setae, posterior part with 

 18—23 setae (after Nielsen). 



Tergites of metanotum (Figure 619) pale yellow; anterior median tergites 

 in form of small sclerotized dots, as in Lepidostoma, with a dark 

 primary seta; posterior median tergites larger, in contrast to Lepido- 

 stoma, each with 15—17 setae; lateral tergites oblong, narrow, concave on 

 median side, with 16—18 setae anteriorly. 



Propleuron mainly light reddish brown with slightly dark pleural groove; 

 episternum much larger than epimeron; trochantin large, broadly black at 

 base, anteriorly with a short, hornlike process with sclerotized dorsal and 

 lateral parts; a dark, relatively large seta ( /a of width of head) near 

 membranous apex; one setule situated subapically, 2nd setule absent. 

 Pleurites of meso- and metathorax yellowish brown; pleural groove dark 

 brown, black distally at articulation, setae black; mesepisternum with one 

 primary seta, mesepimeron with 11—15 setae, one of them primary; 



366 metepimeron with wide, long, anal process, separated from lateral part by a 

 narrow sclerotized area; episternum with 13—15 setae, epimeron with 9—12. 



Legs (Figure 618) reddish yellow; forelegs massive and short, as in 

 Lepidostoma; midlegs longer than other legs; ratio of length of legs 

 67:100:88. Form and chaetotaxy of leg segments as in L. hirtum; light, 

 hairlike chaetoids in distal part of trochanter and at ventral margin of 

 femur of forelegs, in form of a small tuft on mid-trochanter (in contrast 

 to L e p i d o s t o m a), in distal part of hind trochanter and at ventral margin 

 of hind femur. 



Abdomen almost uniformly wide (Figure 619); segment 1 slightly wider 

 than segments following it, segment 9 narrower. Abdominal segment 1 

 without dorsal process; lateral processes with a horseshoe- shaped ridge with 

 small, pointed spinules in anterior half. Dorsal medioanal seta of segment 1 

 slightly shorter than long thoracic setae; intermediate and lateral setae 

 small; anterior-angle seta large, situated dorsal to lateral process; lateral
