Magnified 383X, this scanning electron micrograph (SEM) revealed the morphologic details found at the tip of this adult figeater beetles, Cotinis mutabilis
, maxillary galea, which due to its shape, was given this Latin name for helmet. The galea is located just medial to another, more prominent maxillary appendage, the palpus. Note the concave configuration at the distal tip of the galea, and how there are numerous pointed protuberances inside this concavity, which are most probably sensorial in nature. See PHIL 9933 and 9934, for additional views of this structure at greater magnifications.
