Identification
Glyphuroplata can be distinguished from other Chalepini by characters of the elytral and pronotal structure. The name refers to grooved (from Greek glypho- "carved" and -uro "tail"), suggesting sculpturing. Species-level identification requires examination of male genitalia and elytral punctation patterns: G. uniformis is notably uniform in coloration, while G. nigella and G. pluto exhibit darker markings. G. anisostenoides was described based on structural differences in the prosternal process and elytral intervals.

The occurs in the New World tropics and subtropics. Glyphuroplata pluto is known from Central America and northern South America. Glyphuroplata uniformis and G. nigella have been recorded from the southern United States through Mexico. Glyphuroplata anisostenoides was described from Central American material. Precise range limits for most remain poorly documented.
