8.6–10.4 mm
(m=9.4, n=6). Color: integument dark brown; basic vestiture of minute, cupreous scales; scales light yellow in ovate elytral fascia (Fig. 159); venter with slender whitish scales. Head: frontal fovea deep, rostrum moderate, subcylindrical, sides attenuated between apex and antennal insertion, costate dorsomedially, subcostate dorsolaterally in males, basolateral margin moderately edged, length of rostrum
♂♂
1.12–1.48 x (m=1.29, n=4),
♀♀
1.46–148 x (n=2) pronotal length, length of anteantennal portion
♂♂
0.33–0.43 x (m=0.39, n=4),
♀♀
0.37– 0.39 x (n=2) total rostral length, dorsal margin of antennal scrobe reaching rostral base well before eye; funicular segment 2 distinctly longer than 1, club oblong ovate. Pronotum: length 0.79–0.90 x (m=0.84, n=6) maximum width, widest in basal fourth, then roundly narrowed, anterior portion tubulate; disk finely punctate, intervals rugose. Elytra: length 1.79–1.94 x (m=1.85, n=6) width at humeri, width 1.17–1.32 x (m=1.25, n=6) maximum pronotal width, sides subparallel in basal half, apices rounded conjointly, preapical callus weakly developed, striae fine to obsolete, punctures distinct, interstriae flat, 9 convex. Legs: slender, tibia nearly straight, ventral margin with distal cluster of cupreous hairs, tarsal claws arcuate and separate at base. Male: aedeagus as

Plant association. Not known.
Distribution.
Honduras
and
Nicaragua
, evergreen montane forests (Fig. 240).
Specific epithet. The name is a compound Latin participle derived from flavus (yellow, blond) and plagiatus (spotted).
Discussion.
Embates flavoplagiatus
is related most closely to
A. fasciolatus
. The
two specimens
from
Honduras
exhibit a slightly shorter rostrum than the specimens of the corresponding sex from
Nicaragua
.
