Segmental ratios: 1:1.2:4.4:2.6 (scape, pedicel, postpedicel, style). Scape and pedicel of similar development, orange setose. Postpedicel slightly laterally compressed in cross-section, slightly swollen distally. Style of smaller diameter to distal end of postpedicel, equipped with long brown-orange setae projecting from all surfaces. Face, frons and vertex dull gold pruinose, mystax orange-yellow, ocellar macrosetae orange-brown. Occiput uniformly dull gold pruinose (see Fig. 2A), orange-yellow setose. Face to head width ratio in anterior view 1:3.8 (face narrower than one eye). Proboscis red-brown, straight, pale yellowish setose. Palpi minute, 2-segmented, pale yellow setose.

Thorax: Dark red-brown to black, extensively dull gold pruinose, orange and pale yellow-white setose. Mesonotum: Extensively pruinose with few small apruinose areas (small spot laterally anterior to transverse suture, V-shaped area postsuture). Two orange npl (other macrosetae weakly developed), general setae orange and pale yellow-white. Scutellum dark red-brown, largely apruinose except for two dull gold pruinose areas anteriorly, fine pale yellow setose (apical macrosetae poorly differentiated). Pleura fairly uniformly dull gold pruinose. Katatergal setae orange. Legs: Coxae red-brown, dull gold pruinose, yellow setose. Trochanters brown-orange, pale yellow-white setose. Femora orange with red-brown ring at ⅔ length, mixed orange and pale yellowish setose. Tibiae orange with red-brown ring at ⅔ length and distal region, mostly orange-yellow setose.
