Metatarsus.
Length to metatibia: somewhat shorter.
Metatarsomere 1.
Length to following tarsomeres: subequal or longer than 2–4. GENITALIA.
Aedeagus.
Symmetry: symmetric; Shape: subparallel.
Variability.
Body length:
9.6–10.5 mm
. Without discernible variability except for the size.
Sexual dimorphism
. The species is known only from males. The male has prosternal process with obvious medial carina and protibiae with a comb of long setae on inner margin. These characters in
Agrilus
are a sexual dimorphism.
