Fig. 1
), 2) entirely yellow body (
Figs 1–3
), 3) apical part of hind tibiae and tarsi entirely brown, 4) flagellum black and apically yellow (
Fig. 1
).

5 mm
. Antennae with 30 flagellomeres each. Scapus 0.65 times as broad as long (
Fig. 3
). Head narrowed behind the eyes, shining. Maximal length of temple 0.7 times transverse eye diameter; minimal length of temple 0.5 times transverse eye diameter. Face 0.9 times height of eye; moderately flat, with bulge (
Fig. 3
). Face sparsely covered with pale setae. Interantennal area flat. Clypeus separated from face by transverse groove; projecting anteriorly, with wide central lobe.
