Vertex about 0.2x head width in dorsal view; inner vertical seta and
reclinate orbital seta developed (both damaged in the type material); ocellar setae short but well differentiated from ocellar triangle setulae; fronto-orbital plate with about 12 frontal setae, two of them situated below lower margin of pedicel; fronto-orbital plate almost as wide as parafacial; first flagellomere length about 1.5x length of pedicel; pedicel about 2.8x length of scape; third aristomere about 1.7x length of first flagellomere; facial ridge with a row of stout supravibrissal setae on lower 0.4 of its length, setae 0.2-0.5x length of vibrissa; anteroventral margin of gena with a row of setae extending backward, setae 0.3-0.45x length of vibrissa.
Two pairs of orbital setae, the first proclinate and elevated on separate, raised glossy tubercles; second pair
reclinate, 1/4 as long as first terminally globular pair.
Inner vertical seta very strong,
reclinate and slightly divergent; no outer vertical seta.
Two
reclinate fronto-orbital bristles, anterior bristle ca 0.7 x length of posterior bristle; 1-3 setulae between fronto-orbital bristles, posterior fronto-orbital bristle ca 0.7 x length of inner vertical seta.
Fronto-orbital area with 2 pairs
reclinate fronto-orbital setae, with posterior seta equidistant between anterior seta and inner vertical seta, and with anterior seta slightly closer to lunule than to posterior seta; anterior edge of frons along lunule black, not reaching eye margin laterally.
--Fronto-orbitals comprising 1 proclinate and 1
reclinate seta.
Mesonotum with two narrow, weakly-defined, parallel, medial chestnut-brown pruinose vittae on dorsal surface, extending from anterior margin to region of anterior dorsocentral seta socket; anterior dorsocentral seta much shorter and finer than medial scutellar seta;
reclinate supra-alar seta, slightly shorter than posterior dorsocentral seta; thoracic pleurae silver-grey, yellow pruinose in their centres; postpronotum silver-grey pruinose, with 8-10 fine black-brown setulae; anepisternum silver-grey pruinose, with yellow pruinose patches medially, with 19-20 fine setulae, the 5 larger grouped together at posterodorsal margin; katepisternum with dorsal katepisternal seta ca 0.3 length of ventral katepisternal seta, with 18 short, fine setulae at base and along posterior margin.
half length of medial scutellar seta); presutural seta moderately strong, longer and stronger than posterior notopleural seta; postalar setae shorter and finer than acrostichal setae; postpronotum with 3 strong postpronotal setae, the more dorsal longer and
reclinate, the medial and ventral shorter and proclinate, with 12-14 finer setulae; anepisternum with more ventral anepisternal setae
reclinate, surface with 34 moderately long setulae, those between anepisternal setae longer; ventral katepisternal seta very long and strong, dorsal strong, over half length of ventral, with 22 short, fine setulae at base and along posterior margin.
Anterior fronto-orbital bristles inclinate (incurved), posterior fronto-orbital bristle
reclinate (Fig.
Chaetotaxy: 3 strong orb, 2 hind orb
reclinate, anterior inclinate, pvt distinct and crossed, 1 vti and 1 vte, postocular setulae distinct, generally short, more or less in one row, lower postgenal seta present or absent; mouthparts normal, palp rather broad, almost disc-shaped; antenna with third segment round and arista bare.
Chaetotaxy: 3 orb, anterior inclinate, middle and posterior orb
reclinate, all equidistant from each other; 1 vti and 1 vte a little longer than hindmost orb; pvt crossed, about as long as anterior orb, ocellars a little more than half length of vt; all setae brown.
