( UNMSM); host plant: Eschweilera coriacea . Note: This specimen was reared from a tree at 1000 m along the Plataforma trail; the bait branch was cut during the rainy season (EC-4, I.2004) and suspended in the canopy. Paratypes: Same locality as holotype: 7 males and 8 females, 12° 33’ S, 70° 06’ W / IV.2004– 26.I.2005, host plant data same as holotype; 3 males and 6 females, 12° 34’ S, 70° 06’ W / IV.2004– 26.I.2005, host plant Bertholletia excelsa . [Note: These specimens were reared from tagged tree 0 2 at 128 m along the Aerodromo trail, the bait branches were cut during the rainy season (BE-4, I.2004). One female was reared from a bait branch at ground stratum; others were from canopy stratum]; 1 female, 12° 32’ S, 70° 05’ W / 24.I.–10.VIII.2004, host plant B. excelsa [Note: This specimen was reared from a tree at 350 m along the Trompeteros trail, the bait branch was cut during the dry season and suspended in the canopy (BE-2; VIII.2003)].

Description. Male ( Figs 5 , 8 , 10 , 18–19 ): integument light to medium reddish brown; body pubescence short and appressed, tan with ivory and medium brown markings. Head with frons, gena, and vertex ivory, pubescence densest bordering side of eye and posterior to the superior lobe, brown macula on antennal socket, scape ivory-tan with medium brown macula at dorsal apex, all other antennomeres ivory-tan at base, grading to medium brown at apex. Pronotum ivory-tan, with brown fascia near apex and subtler semicircular brown fascia terminating in conspicuous lateral spots, subtended by inverted v-shaped brown macula (sometimes reduced to two maculae with tan at apex). Scutellum piceous. Elytra mostly tan with numerous scattered brown maculae, ivory maculae shadowed in brown forming a rough “x” across suture, and oblique ivory fasciae near apices. Prosternum with ivory appressed pubescence, meso- and metasternum with moderately dense, erect ivory pubescence, metasternum with lateral brown maculae. Abdomen with integument light reddish-brown, segment 1 with medial erect ivory pubescence and lateral appressed ivory pubescence with subtle brown macula, segments 2–5 with appressed ivory pubescence, segments 2–4 almost glabrous medially, with subtle brown lateral macula. Legs with integument light reddish-brown, coxae with dense, erect ivory pubescence, femora and tibiae with patchy appressed ivory and tan pubescence, dorsum of meso- and metatarsi predominantly ivory.

Head slightly convex, antennae attaining elytral apex at approximately end of antennomere 5, antennomeres 10 and 11 similar in length. Pronotum transverse, sides with obtuse post-medial tubercles terminating in small spines, coarse punctures in basal impression. Scutellum triangular, truncate at apex, raised above base of elytra. Elytra approximately twice as long as humeral width, with erect setae, slight central basal gibbosity, coarse punctures extending from base to the apical one-quarter of elytra, apex obliquely truncate with sutural angle rounded. Prosternal process extremely narrow, less than one-sixth width of procoxa, apex expanded posteriorly, anterior margin of mesosternum sinuate, mesosternal process about width of mesocoxa. Abdomen with apical sternite semicircular and apical tergite emarginate (truncate). Pro- and mesofemora strongly clavate, mesofemora with coarse tooth near apex of internal side, pro- and mesotibiae with margins of ventral face carinate, mesotibial carinae more conspicuous with stiff bristles, first tarsomere of hind leg longer than next two tarsomeres together. Genitalia: Median lobe 2.2 mm long, basal apophyses about one-third of entire median lobe in length, apex of dorsal lobe sagitate, apex of ventral lobe lightly, medially sclerotized. Tegmen 2.3 mm long, extended base (fused part) about four times as long as paramere, ring elbowed, unfused portion of parameres 0.1 mm long, touching medially, widest near base, apices with several long setae, the longest about as long as paramere.

Female ( Figs 13 , 20 ): Similar to male except venter lacks erect ivory pubescence, mostly covered by sparse appressed ivory pubescence, except for brown lateral maculae on metasternum and abdominal segments 1–4, apex of ovipositor grading to brown with dark terminal setae. Antennae attaining elytral apex at approximately middle of antennomere 6, apical sternite and tergite elongated to form ovipositor extending well beyond elytral apex, pro- and mesofemora less strongly expanded, and mesofemora without coarse tooth. Genitalia: spermatheca 0.7 mm long, symmetrically indented forming duct at obtuse angle.

Dimensions, in mm.

Comments. This species is distinguished from Baryssiniella tavakiliani by the following characters: the integument predominantly light reddish-brown, the light color of the appressed pubescence, which ranges from ivory to medium brown, the brown macula in the form of an inverted “v” on the medial pronotum (sometimes reduced to two maculae), the ivory maculae, shadowed in brown, forming a rough “x” on the elytra, and males with a coarse tooth near the apex of the enlarged mesofemora.

Host plants. Eschweilera coriacea and Bertholletia excelsa , reared preferentially from bait branches cut during the rainy season and suspended at canopy stratum.

GenBank accession numbers. GU827559 (1 female, #A10-1, IV.2004 – I.2005), GU827560 (1 male, #A10-3, IV.2004 – I.2005).

Etymology. From Latin hieroglyphicus, sacred carving, the specific epithet refers to the elegant and complex pubescence pattern.
