Ambrosiodmus brunneipes (Eggers): Wood and Bright, 1992: 671. 

Diagnosis

3.2−3.4 mm long (mean = 3.38 mm; n = 5); 2.43−2.5 times as long as wide. This species can be distinguished by the elytralelytral:
pertaining to the elytra
declivitaldeclivital:
pertaining to the elytral declivity
interstriae with uniformly sized and spaced granulesgranule:
a small rounded protuberance, like grains of sand
from basebase:
point or edge closest to the body; opposite of apex
to declivitaldeclivital:
pertaining to the elytral declivity
midpoint; apicalapex:
point or edge furthest from the body; opposite of base
half of interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
with granulesgranule:
a small rounded protuberance, like grains of sand
irregularly spaced; declivitaldeclivital:
pertaining to the elytral declivity
interstriae slightly elevated and bearing thick, erecterect:
pertaining to setae that have their apices directed away from the body and appear straight
setae, setaeseta:
small hair-like or scale-like structure
located ventrad of granules; declivitaldeclivital:
pertaining to the elytral declivity
surface strongly shagreenedshagreened:
covered with a closely-set roughness, like shark skin
; and dark brown color.

This species is very similar to A. conspectus and can be distinguished by the larger size and 5−6 granulesgranule:
a small rounded protuberance, like grains of sand

point or edge furthest from the body; opposite of base
