the part of any appendage or structure that is nearest the body
and end of elytraelytron:

much longer than wide
, scapescape:
the first proximal segment of the antenna

the first proximal segment of the antenna

Differential diagnosis

Anelaphus is distinguished from closely related genera by the pubescentpubescent:
downy; clothed with soft, short, fine, loosely set hair
patches on the antennal tubercles, lack of antennal carinaecarina:
an elevated ridge or keel, not necessarily high or acute
, antennal spines on at least antennomereantennomere:
a subunit of the antenna, including the scape, pedicel, and flagellomeres
3, and 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
being rounded apicolaterally.
