Key to known pupal cases of Laphriinae   Edit genera

1 Head with 5 basally fused posterior antennal processes; median facial spines bifurcate or trifurcate, face lacking median or anterior bristle between spines; abdominal segment 1 with broad dorsal, bifurcate or trifurcate spine; abdominal segment 3 with median space interrupting ventral transverse row of spines; abdominal segments 4–7 with no median space interrupting ventral row of spines, but median spines often shorter than surrounding spines............................... Lampria   Edit

- Head with 3–5 basally fused posterior antennal processes; median facial spines usually not bifurcate or trifurcate, face with or without median, anterior or posterior bristle between spines; abdominal segment 1 usually without dorsal median bifurcate or trifurcate spine, but, if present, spine not broad; segments 3–7 with or without median space interrupting ventral transverse row of bristlelike spines, but if median space present it may become smaller posteriorly and/or have shorter median bristlelike spines than surrounding spines........................................................................... 2

2 Abdominal segments 3–7 or 4–6 with median space interrupting ventral transverse row of bristlelike spines; head with 3–5 basally fused posterior antennal processes; facial area with or without bristle between or posterior to median spines; abdominal segment 1 with or without dorsal median bifurcate spine, other dorsal spines sometimes bifurcate................ Laphria   Edit

- Abdominal segments 4–7 without median space interrupting ventral transverse row of bristlelike spines; head with 3–4 basally fused posterior antennal processes, 4 th process small; facial area with bristle between or anterior to median spines; abdominal segment 1 without dorsal median bifurcate or trifurcate spines, although other spines sometimes bifurcate.....
