Comments.

The original description suggests that this species belongs in Gryon and so we leave it here for now, albeit without great confidence: "head wider than thorax, slightly arched back, twice as wide as long, smooth and shiny on the front which gives an unlimited frontal impression, finely chagrined on the rest."
