ETYMOLOGY. — The species name breviróstris is a Latin noun formed from brevis = short, and rostris = from the adjectivised noun rostrum = face for snout or proboscis.
REMARKS. —
The
two specimens
from
Mt Mou
have the sides of the pronotum densely squamose with large, imbricate, yellowish brown scales.
The
small specimen from

that lacks a precise locality has the sides of the pronotum loosely squamose with small, sparse white scales
