Antenna as in Figure 5; three articled, antennomere 1 transverse, 
about 2.5 times as wide as long, with 5 campaniform sensillae equi- 
distant around apex; article 2 about 2.9 times as long as 1, constricted 
apical portion about 0.24-0.25 times length of 2; article 3 about 0.5 
times length of 2; sensory appendage of antennomere 2 inflated, 
more or less parallel sided and obtusely and bluntly pointed, about 
1.8- 1.9 times length of constricted portion of antennomere 2; 
antennomere 2 with solenidia IIS 1-3 present, IIS 1 more or less 
digitiform, slightly tapering to obtusely rounded apex, about 
0. 5-0.6 times length of sensory appendage, IIS2 spinose, about 
0. 3-0.4 times length of IIS 1 , IIS3 very small, spinose; solenidia of 
antennomere 3 with IIIS1 setose, as long as IIIS2+3, IIIS2 and IIIS3 
fused, IIIS2 present as slight projection on side of IIIS3; IIIS4 
setose. Labrum as in Figure 6; not separated from head capsule by a 
suture; anterior margin protruded as broad, truncate, parallel sided 
lobe; with dome-like microsculpture medially and latero-medially; 
not divided by sutures into distinct sclerotized areas; all normal 
setae present, setiform, Ldl and Ld2 small, Ldl larger than Ld2, 
other labral setae larger. Epipharynx as in Figure 7; with patch of 
densely arranged, well developed rows of spines medially. Mandi- 
bles (Figure 3) curved apically, flattened and broad internally, with- 
out molar lobe basally; internal tooth in dorso-ventral plane, 
forming a distinctly bilobed apex to mandible with ventral tooth 
larger than dorsal tooth, edges of apical teeth serrate; 2 setae present 
externally in basal half, more proximal seta much larger than very 
small distal seta. Maxilla (Figure 9) with cardo broadly oval, 
incompletely divided medially by internal sclerotized ridge, with 
moderate seta on antero-lateral margin; stipes rounded at base, not 
distinctly separated from mala by suture; mala (Figure 9) with apex 
oblique, adorai surface with several setae and numerous blade-like 
cuticular spines, proximal seta blade-like, proximal spine thickened, 
longer than wide, blunt at apex; mala with 2 large setae near lateral 
margin, dorsal surface with scattered, minute cuticular spines; max- 
illary palpus (Figure 9) of three articles and palpifer consisting of 
cresentric sclerite at base of palpus, surface of palpifer with 1 seta 
and 1 campaniform sensilla, article 1 1.3 times as long as 2, article 3 
1.4 times as long as 2 and 3 together, article 3 with small digitiform 
sensory appendage on external surface. Labium (Figure 8) consist- 
ing of premental and fused mental-submental sclerites; ligula trans- 
verse, about 2.5 times as long as wide, broadly rounded apically;
