; funicle length:
0.85 mm
. Scape length/funicle length ratio: 1.05. Antenna segments ratios as follows: 10: 7: 5: 6: 5: 5: 4: 28 (club); fusiform club with first segment flat, more long than five last funicle segments, at least twice wider than funicle. Head smooth on disc, short, conical. Supraorbital area covered by dense yellowish pubescence. Vertex width / mesorostrum width: ratio 1.72. Vestigial eyes visible, partially covered by yellowish pubescence. Pronotum (length:
