Description. Habitus: Fig. 170, total length 6.8–9.4 mm (m=8.4, n=24). Color: integument rufous­castaneous; basic vestiture of minute, translucent scales, scales yellow in dorsolateral pronotal vitta, compound basal elytral vitta and subapical fascia (Fig. 170a, b); venter with yellow scales on prosternum and along flank. Head: frontal fovea minute, rostrum moderate, subcylindrical (Fig. 171), sides attenuated between apex and antennal insertion, costate dorsomedially, basolateral margin moderately edged, length of rostrum ♂♂ 1.11–1.29 x (m=1.20, n=13), ♀♀ 1.22–1.38 x (m=1.28, n=11) pronotal length, length of ante­antennal portion ♂♂ 0.33–0.44 x (m=0.37, n=12), ♀♀ 0.39–0.44 x (m=0.41, n=12) total rostral length, dorsal margin of antennal scrobe reaching rostral base before eye; funicular segment 2 longer than 1, club oblong ovate. Pronotum: length 0.87–0.92 x (m=0.89, n=24) maximum width, sides subparallel to rounded in basal third, then roundly narrowed, anterior portion tubulate; disk densely and very shallowly punctate, intervals very narrow, subcostate dorsomedially or not. Elytra: length 1.79–1.96 x (m=1.87, n=24) width at humeri, width 1.28–1.35 x (m=1.31, n=24) maximum pronotal width, sides sub­ parallel or very slightly converging in basal half, apices rounded separately, preapical callus developed moderately, striae fine, punctures indistinct, interstriae flat, 9 subcostate distally. Legs: moderately stout, tibia slightly curved, ventral margin with distal cluster of cupreous hairs, tarsal claws flat and approximate at base. Male: sides of apex converging gradually, anterolateral portion membranous, apex sclerotized (Fig. 172), body of aedeagus elongate, basal third angular in lateral view, apodemes 1.9 x longer than body of aedeagus, flagellum thin, longer than apodemes, transition to base gradual, basal appendage elongate, fused subdistally with base of flagellum, projecting beyond base (Fig. 173).

Plant association. Piper cordulatum (Stockwell 1)

Distribution. Central Panama (Fig. 248).

Specific epithet. The name is a Latin adjective meaning “quite similar”.

Discussion. Embates consimilis is a close relative of E. rhombifer , with some similarities to E. latevittatus . The species can be recognized by separately rounded elytral apices, subconnate claws and the color­pattern. In small specimens, the subapical fascia may blend with the dorsolateral elytral vitta, so the color­pattern approaches that of E. latevittatus .
