Description. Habitus: as Fig. 170, total length
6.3–8.2 mm
(m=7.3, n=51). Color: integument rufouscastaneous; basic vestiture of small to mediumsized cupreous scales, scales yellow in broad dorsolateral pronotal and fuzzy elytral vittae between humerus and preapical callus (Fig. 174); venter with yellow scales on prosternum and along flank. Head: frontal fovea minute or obsolete, rostrum moderate, subcylindrical (as Fig. 171), sides attenuated between apex and antennal insertion, costate dorsomedially, basolateral margin moderately edged, length of rostrum

1.15–1.38 x (m=1.23, n=26),
♀♀
1.20– 1.41 x (m=1.29, n=25) pronotal length, length of anteantennal portion
♂♂
0.33–0.39 x
(m=0.36, n=26),
♀♀
0.40–0.46 x (m=0.42, n=25) total rostral length, dorsal margin of antennal scrobe reaching rostral base before eye; funicular segment 2 longer than 1, club oblong ovate. Pronotum: length 0.82–0.95 x (m=0.89, n=51) maximum width, sides subparallel to slightly rounded in basal half, then roundly narrowed, anterior portion tubulate; disk densely and very shallowly punctate, intervals very narrow, subcostate dorsomedially or not. Elytra: length 1.75–1.98 x (m=1.87, n=48) width at humeri, width 1.26–1.42 x (m=1.32, n=51) maximum pronotal width, sides subparallel in basal half, apices rounded separately, preapical callus developed moderately, striae fine, punctures indistinct, interstriae flat, 9 subcostate. Legs: moderately stout, tibia slightly curved, ventral margin with distal cluster of cupreous hairs, tarsal claws flat and approximate at base. Male: aedeagus as
E. consimilis

Distribution.
Costa Rica
and
Panama
, Atlantic side of Cordilleras (Fig. 248).
Specific epithet. The name is a Latin adjective meaning “reddish”.
Discussion.
Embates rutilus
belongs to a group of species with singularly rounded elytral apices, represented in Middle America by
E. justini
,
E. rhombifer
and
E. consimilis
. The elytral vitta is illdefined in the specimens from the lowlands, but welllimited in the specimens from La Fortuna, at higher elevations.
