the leg segment distal to the apex of the tibia, bearing the pretarsus; consists of one to five tarsomeres (including pretarsus)
almost same as long as the following two segment combined; claws usually without distinct appendage (Hasegawa and Ohbayashi 2001Hasegawa and Ohbayashi 2001:

Differential diagnosis

Can be distinguished from subgenus Miccolamia by the simple tarsal claws. The inflated clavateclavate:
thickening gradually toward the tip
scape, very small size, and rounded elytral apicesapex:
end of any structure distad to the base
will distinguish from Pogonocherus.
