Description. Habitus: as Fig. 152, total length 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 E. obliquus .

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.
