Redescription. Habitus: Fig. 43, total length 3.9 mm (all meristic data were taken from female paratype of NMNH). Color: integument piceous, antenna and tarsi rufous; basic vestiture of cupreous scales, scales black in irregularly shaped elytral macula between interstriae 2–5 (Fig. 43), scales creamy white in thin dorsolateral pronotal vitta and in postmacular fascia between interstriae 3–4 and 8–9 (vestigial), ante­macular fascia faintly visible in outer elytral interstriae; venter with spot of creamy white scales in ante­coxal portion of prosternum, vestiture sparse elsewhere. Head: frontal fovea absent, rostrum moderately thick, moderately falciform, costate dorsomedially, basolateral margin produced, length of rostrum 1.11 x pronotal length, length of ante­antennal portion 0.37 x total rostral length, dorsal margin of antennal scrobe reaching rostral base before eye; length of funicular segments 1 and 2 subequal, club oblong ovate. Pronotum: length 0.89 x maximum width, sides parallel in basal half, then abruptly constricted and tubulate in front; disk densely punctate, intervals granulose. Elytra: length 1.67 x width at humeri, width 1.45 x maximum pronotal width, sides subparallel in basal half, apices rounded conjointly, preapical callus developed moderately, striae fine, punctures rather indistinct, interstriae flat, 9 subcostate. Legs: tibiae curved, ventral margin weakly bisinuate, distally with cluster of cupreous hairs, tarsal claws arcuate and separate at base. Male: not examined.

Plant association. Not known.

Material examined. GUATEMALA. Guatemala: Zapote (former suburb of Guatemala City now engulfed by municipality, Fig. 244) ( BMNH 5 , NMNH) .

Discussion. Embates exclamationis is known only from the type series collected by Champion. Those six specimens are very similar in size and vestiture, and nothing is known about the variability of the species. The outer elytral interstriae exhibit traces of ante­ and post­macular elements.
