2.76 - 3.28 mm, piceous above, the elytra slightly brownish, the 
appendages obscurely paler. Elytral pubescence moderately sparse, 
appressed, that from base to posterior border of weak postbasal 
transverse impression cinereous, the rest brown. The pale pubescence 
is much more noticeable, but is no denser than the rest. Sides and 
base of pronotum also with some cinereous pubescence, that on disc

between them. A line connecting the backs of the eyes is 0.15 mm 
from the middle of the base. Disc slightly flattened, densely covered 
with sharply defined flat-bottomed punctures, even on frons, the 
punctures ca. 0.03 mm from center to center, the intervals narrow, 
less than half the diameter of the punctures, shiny; the punctures
