Color: integument piceous, basic vestiture of brown and some lightcolored scales, yellow scales condensed in narrow subapical elytral fascia, small spots at interstria 6 (Fig. 114) and dorsolateral pronotal vitta, scales light yellow ventrally. Head: frontal fovea absent, rostrum slender, subcylindrical, curved (similar to Fig. 110), costate dorsomedially, basolateral margin slightly edged, length of rostrum ♂♂1.23–1.37 x (m=1.29, n=8), ♀♀1.26– 1.34 x (m=1.31, n=5) pronotal length, length of anteantennal portion ♂♂0.38–0.40 x (m=0.39, n=8), ♀♀0.41–0.43 x (m=0.42, n=5) total rostral length, dorsal margin of antennal scrobe reaching rostral base before eye; funicular segment 2 much longer than 1, club oblong ovate. Pronotum: length 0.89–0.99 x (m=0.95, n=13) maximum width, subconical, widest in basal third, anterior portion tubulate; disk densely and shallowly punctate. Elytra: length 1.74–1.85 x (m=1.79, n=13) width at humeri, width 1.35–1.50 x (m=1.41, n=13) maximum pronotal width, sides subparallel in basal half, then increasingly narrowed toward apex, apices rounded conjointly, preapical callus costate, striae fine, punctures moderate, interstriae flat, 9 costate. Legs: tibiae nearly straight and parallelsided, distally with cluster of cupreous hairs, tarsal claws arcuate and separate at base. Male: apex of aedeagus broadly rounded, middle sclerotized, anterolateral portion membranous (Fig. 115), body of aedeagus short, basal third angular in lateral view, apodemes approximately 2.8 x longer than body of aedeagus, flagellum thin, shorter than apodemes, transition to curved base gradual, basal appendage moderate, fused laterally with base of flagellum, projecting beyond base (Fig. 116). Plant association. P. glabrescens(Prena 2), P. aequale(Prena 1), P. tenuimucronatum(Prena 1), P. dotanum(Prena 1). Distribution. Costa Ricaand Panama, evergreen montane forests of Atlantic side between 800 and 1800 m(Fig. 257). Specific epithet. The name is a compound Latin participle derived from todillus (thin) and fasciatus (striped). Discussion. Embates todillofasciatusis an uncommon species of the premontane forests in the Cordilleras Central and Talamanca. It belongs to the complex of slender species near E. pictipennis, and can be recognized easily by its colorpattern (Fig. 114). The narrow transverse line of lightcolored scales derives from the postmacular element of a former elytral macula. The hypothesized ancestral colorpattern can be seen in the South American E. delicatulus(Hustache)( Fig. 27).
