the part of any appendage or structure that is nearest the body
and end of elytraelytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose

the first proximal segment of the antenna
cicatrixcicatrix:
a scar; a scar-like structure
(scar) at apexapex:
end of any structure distad to the base

Prosternum: prosternal process dilated at apexapex:
end of any structure distad to the base
, procoxal cavities closed posteriorly.

. ElytraElytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose

Differential diagnosis

Lamia does not have any maculaemacula:
a spot or mark
on the elytraelytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose

Distribution

Neotropical (Brazil, L. annulicornis), Palearctic (L. textor)

Recorded host plants

broadleaf trees; Pinaceae recorded as well

Remarks

2 species. Lamia annulicornis is incerte sedis in Lamiinae so likely belongs elsewhere.
