Similar Taxa
- Phyllophaga cribrosaAlso flightless with oval, convex, black body, but distinguished by distinct longitudinal elytral furrows and cribrose (sievelike) surface texture; P. hirtiventris lacks these furrows
- Phyllophaga epigaeaClosely related flightless restricted to Texas; lacks distinct elytral furrows found in P. cribrosa, making separation from P. hirtiventris difficult without genital examination
- Phyllophaga zavalanaAnother Texasrestricted flightless relative; morphologically similar to P. epigaea and potentially confusable with P. hirtiventris without detailed examination
