Taxonomic history

Xyleborus conspectus Schedl, 1964b: 247.

Ambrosiodmus conspectus (Schedl): Wood and Bright, 1992: 672.

Diagnosis

2.9−3.1 mm long (mean = 3.01 mm; n = 5); 2.48−2.73 times as long as wide. This species can be distinguished by declivitydeclivity:
downward slope of either the pronotum or elytra
with uniformly sized and spaced granulesgranule:
a small rounded protuberance, like grains of sand
on declivitaldeclivital:
pertaining to the elytral declivity
interstriae from basebase:
point or edge closest to the body; opposite of apex
to declivitydeclivity:
downward slope of either the pronotum or elytra
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. brunneipes and can be distinguished by the smaller size and the 3−4 granulesgranule:
a small rounded protuberance, like grains of sand
on the apicalapex:
point or edge furthest from the body; opposite of base
half of declivitaldeclivital:
pertaining to the elytral declivity
interstriae 1.
