, 12): Four-segmented, slender, about half as long as length of head capsule. Inserted on anterolateral corners of head capsule. First antennomere about twice as long as wide, wider than remaining antennomeres. Antennomere 2 the longest, about 5Χ long as maximum width, more slender basally, gradually widening distally; with one small apical conical sensillum, accompanied by several small peg-shaped sensilla and pores. Antennomere 3 slender, slightly longer than antennomere 1 and slightly shorter than 4, lacking sensilla. Antennomere 4 very slender, rounded apically, with 6 short setiform sensilla distally.

, 13): Free, not connected with labium; formed by cardo, stipes, palpifer, a 4-segmented palpus, galea and lacinia. Cardo large, undivided, bearing one long, central seta ventrally. Stipes subriangular, smaller than cardo, outer margin with five long setae; two additional setae ventrally, one near central area, the other subbasally on inner margin. Lacinia attached to dorsal inner margin of stipes, large, hook-shaped, basally with six rather large setae on inner margin, two very stout setae at midlength on inner margin, four or five more short and stout setae on distal half of inner margin. Palpifer attached to ventral distal margin of stipes, large, subrectangular, longer than wide, bearing three slender setae on ventral side. Galea one-segmented, cone-shaped, with one slender seta on inner margin at midlength and several small apical sensoria. Palpus four-segmented, palpomere 1 the shortest, wider than long, bare; palpomere 2 the longest, with one long apical seta on outer margin; palpomere 3 shorter, with two setae, one short on inner margin, the other long, apical, on ventral side; palpomere 4 as long as palpomere 3, narrower, cone-shaped, bare.

Submentum large, subrectangular, wider at midlength, twice as long as wide, ventrally with a pair of lateral stout and long setae on basal third, two smaller and slender setae closer to midline at distal third. Mentum subquadrate, slightly narrower than prementum, incompletely sclerotized, distal half membranous; three lateral slender setae at midlength on each outer margin. Prementum wider than long, with well-developed membranous ligula, bearing several pairs of long and slender setae on dorsal, lateral and ventral sides. Palpus three-segmented, basal palpomere the shortest, slightly wider than long, with two apical setae on outer margin, one long and stout, the other very short; second palpomere the longest, twice as long as wide, curved inwards, bearing two long setae, one on basal third, the other subapical; third palpomere cone-shaped, bearing several apical sensoria.
