Comments.

The original description is of no use for placing this species in either Gryon or Hadronotus . Mineo (1990) illustrated a female antenna of this species as having five clavomeres but did not clarify if this was the holotype specimen. He mentioned that type material was examined but did not clarify if this was type material of H. fellah , H. nigricornis , or both. Hadronotus fellah clearly belongs in Hadronotus based on images of the holotype (USNMENT01059669). However, H. fellah was described from Egypt, and while it is possible that H. fellah and H. nigricornis are conspecific, we consider it prudent to reexamine this synonymy.
