Occiput dorsomedially concave, largely blackish brown (only ventral marginal area ochreous) and sparsely grey microtomentose but shining. Frons largely dull and yellow, only frontal (including ocellar) triangle brown to dark brown and shining. Frontal (and ocellar) triangle with sparse grey microtomentum; its narrowed and acutely projecting anterior corner yellow and dull. Ocellar triangle coloured and microtomentose as surrounding frontal triangle. Orbit largely yellow and entirely silvery white microtomentose, behind posterior ors usually darker, ochreous to pale brown; a silvery white microtomentose stripe between posterior part of orbit and frontal triangle broad and anteriorly connected with similarly microtomentose orbit and also very narrow marginal line of frontal triangle. Rest of frons yellow, without microtomentum but dull. Frontal triangle relatively short and narrow, reaching anterior third (its brown part only half) of frons. Frontal lunule yellow, small and narrow. Face narrow, medially weakly sclerotized and concave, all yellowish white, whitish microtomentose and dull; border line separating it from parafacialia ochreous to yellow. Parafacialia and gena also yellowish white but densely silvery white microtomentose; ventral marginal stripe on gena ochreous-brown and posteriorly dilated. Postgena yellow, posteriorly ochreous as also is ventral band of occiput. Mouthparts dirty yellow, with paler (whitish yellow) palpus and darker (ochreous-brown) clypeus and prementum. Cephalic chaetotaxy: pvt distinct but fine, with apices crossed; vti and oc subequal, very long, longest of cephalic setae; oc proclinate, slightly divergent; vte and posterior ors subequal, distinctly shorter than vti; 2 ors, anterior long, only slightly shorter than posterior; 1–3 microsetula(e) in front of the anterior ors; 3–4 pairs of medial microsetulae in front of frontal triangle; 1 inclinate short seta behind vte; postocular setulae relatively long and sparse (about 6–8), in single row; postgena with several setulae and 2 (1 longer) pale posteroventral setae; 1 rather weak vi (about as long as but finer than anterior ors); subvibrissa distinct, up to three-fourths of vi length but finer, longer than peristomal setulae; 6–7 fine peristomal setulae. Palpus slender, dirty yellow, with 1 fine dark ventral preapical seta (as long as but thinner than subvibrissa) and a number (about 10) of paler ventral setulae. Eye large, suboval, with longest diameter very slightly oblique, 1.3–1.4 times as long as shortest. Gena relatively high (deep), its shortest height about 0.14–0.15 times as long as shortest eye diameter. Antenna with scape and pedicel yellow; 1st flagellomere pale to whitish yellow, with short white pilosity including cilia on anterior margin. Arista pale brown, with somewhat thickened basal segment, 2.1–2.2 times as long as antenna, with yet shorter cilia than those on apex of 1st flagellomere.
