2 Dorsum of head behind clypeus reticulate-punctate.

3 Ventrolateral margin of head when viewed from above extremely shallowly evenly concave in front of eye.

4 Upper scrobe margin with a row of anteriorly curved narrowly spatulate short hairs; more posteriorly the hairs finer and simple, longer and more strongly projecting.

5 Dorsum of head from posterior margin of clypeus to level of the posterior margins of the eyes densely clothed with very conspicuous appressed spatulate hairs.

6 Hairs on dorsum of head close to occipital margin suberect, short and simple.

7 Hairs on leading edge of scape very narrowly spatulate, not spoon-shaped.

8 Pronotal dorsum with ground pilosity that is simple and blunt apically.

9 Erect hairs on mesonotum simple.
