SUMMARY
Allograpta flavophylla belongs to a group, subgenus Rhinoprosopa, characterized by: face greatly produced anteriorly, with low indistinct tubercle or no tubercle; oral opening about 5.5 times as long as wide, with oral apex greatly extended beyond level of antennal base; antennal pits distinctly separated; plumula absent; subscutellar pile fringe absent; wing microtrichose, without apical dark macula; alula absent or narrow, less than 1/2 as wide as cell BM; metasternum bare; abdomen narrowly to strongly petiolate (Mengual et al. 2009).
