Redescription. Habitus: Fig. 100, total length 3.0– 4.8 mm(m=3.9, n=30). Color: integument piceous; basic vestiture of brown and some slender, ochreous scales; ochreous scales condensed in small macula at elytral interstria 5 (indistinct at 3), in apical portion of elytron and in dorsolateral pronotal vitta; venter with slender, lightcolored scales. Head: frontal fovea absent, rostrum moderately stout, subcylindrical, curved, subcostate dorso medially and dorsolaterally, basolateral margin edged, length of rostrum ♂♂1.10–1.23 x (m=1.17, n=11), ♀♀1.08–1.23 x (m=1.18, n=17) pronotal length, length of anteantennal portion ♂♂0.39–0.41 x (m=0.41, n=11), ♀♀0.39–0.46 x (m=0.42, n=17) total rostral length, dorsal margin of antennal scrobe reaching rostral base before eye; funicular segment 2 longer than 1, club oblong ovate. Pronotum: length 0.84–0.94 x (m=0.89, n=29) maximum width, sides rounded, greatest width close behind middle, anterior portion tubulate. Disk densely and shallowly punctate, intervals isolated. Elytra: length 1.56–1.75 x (m=1.67, n=27) width at humeri, width 1.23–1.43 x (m=1.32, n=29) maximum pronotal width, sides subparallel in basal half, then increasingly narrowed toward apex, apices rounded conjointly, preapical callus developed moderately, striae moderate, punctures indistinct, interstriae flat, 7 and 9 subcostate. Legs: tibiae variously curved, ventral margin slightly bisinuate, distally with cluster of cupreous hairs, tarsal claws arcuate and separate at base. Male: apex of aedeagus round, middle sclerotized, anterolateral portion membranous (as Fig. 98), body of aedeagus of moderate length, basal third angular in lateral view, apodemes 2.3 x longer than body of aedeagus, flagellum thin, half as long as apodemes, transition to curved base gradual, basal appendage moderate, fused subdistally to base of flagellum, projecting beyond base (Fig. 101). Plant association. Piper hispidum(Prena 2), P. urostachyum(Prena 8). Distribution. Hondurasto central Panama, secondary forests (Fig. 253). Material examined. HONDURAS.

Chiriquí: Bugaba( BMNH). Coclé: El Valle, 700–850 m( HPSC 2). Total 86 specimens. Discussion. Embates apicaliscan be confused with several species of equally small size. Embates tergosignatusand E. thoracicusare slightly stouter, have very narrow elytral striae and flat interstriae. Embates gracilisis more slender, and has a shorter rostrum. Embates todillofasciatusis larger and more elongate. The distinction of these species is straight forward when the vestiture is intact and can be used for identification.
