Definition:

The facial area of the cranium lying between the postfrontal sutures dorsally and the epistomal suture ventrally; largely obscured by the convergent antennal sockets; comprised of a narrow ventral prefrons between the convergent antennal sockets and a broader dorsal postfrons bearing the antennal pulsating organ.

Explanation:

The “frons” is delimited in various ways by different authors and in different insects and stages and thus is not morphologically equivalent except in limited cases.

Synonyms:

front, frontal area, postfrons (in part), vertex (in part)
