Body size 307–365 × 199–232. Body surface foveolate. Rostral and lamellar setae of medium size, slightly barbed; interlamellar setae short, thin, smooth. Sensilli clavate; sensillar head with several barbs distally. Tutoria fused distally to prolamellar lines. Anterior notogastral margin regular convex. Notogastral setae of medium size, smooth. Postanal porose area present. Ventral setae short, smooth. Legs monodactylous.
Measurements. Body length: 307–365 (eight specimens); notogaster width: 199–232 (eight specimens).
Integument. Body color light brownish. Body surface foveolate (diameter of foveolae up to 4 on rostrum, up to 3 on notogaster and ventral side, up to 2 on medio-basal part of prodorsum). Foveolae located densely on prodorsum, but sparse on notogaster and ventral side. Also microgranules present on prodorsum.
Prodorsum. Rostrum rounded. Lamellae located dorso-laterally, longer than half of prodorsum, reaching insertion of lamellar setae. Prolamellar lines well developed. Rostral (32–41) and lamellar (49–57) setae setiform, slightly barbed. Interlamellar setae thin, smooth, shorter (28–32) and thinner than lamellar setae. A pair of elongate, narrow porose areas Ad present latero-posterior to interlamellar setae (visible only in dissected specimen). Exobothridial setae and their alveoli absent. Sensilli longest setae on prodorsum (61–73), with long stalk and clavate head; sensillar head with several barbs distally. Tutoria long, fused distally to prolamellar lines forming point tip (t), not reaching to insertions of rostral setae. Sublamellar lines short, thin, straight. Sublamellar porose areas small, rounded (4–8). Porose areas Am and Ah not observed.
Notogaster. Anterior notogastral margin regular convex. Dorsophragmata and pleurophragmata distinct. Pteromorphs sub-triangular. Notogastral setae represented by 10 pairs; they of medium size (p1–p3, 16–20; others, 24–32), thin, smooth. Four pairs of sacculi (Sa, S1, S2, S3) with small openings, but S2 and S3 visible only in dissected specimens. Lyrifissures and opisthonotal gland openings located typically for the genus (see Beck 1965). Postanal porose area oval (12 × 4).
Gnathosoma. Subcapitulum longer than wide (73–82 × 61–69). Subcapitular setae setiform, smooth; h (12) longer than m (6) and a (10). Two pairs of adoral setae (8) setiform, slightly barbed. Palps (41–45) with setation 0–2–1–3–9(+ω). Solenidion thickened, attached with eupathidium. Chelicerae (73–82) with two setiform, ciliate setae; cha (28–32) longer than chb (16–20). Trägårdh’s organ conical.
Epimeral and lateral podosomal regions. Apodemes 1, 2, 3 and sejugals well developed. Epimeral setal formula 3–1–3–3; setae short (4–6), setiform, smooth. Pedotecta I, II, discidia and circumpedal carinae developed typically for the genus (Beck 1965).
Anogenital region. Five pairs of genital (g1, 14, g2–g5, 6–8), one pair of aggenital (6–8), two pairs of anal (6–8) and three pairs of adanal (6–8) setiform, thin, smooth. Lyrifissures iad in paraanal position.
Legs. All tarsi with one strong, smooth claw. Formulae of leg setation and solenidia: I (1–5–3–4–20) [1–2–2], II (1–5–2–4–15) [1–1–2], III (2–3–1–3–15) [1–1–0], IV (1–2–2–3–12) [0–1–0]; homology of setae and solenidia indicated in Table 2.
Eight specimens (five females and three males): Ec-1.
Actually the name of this species was first made available by Beck (1963) as Rostrozetes glaber, but its description was published later (Beck 1965). Judging on his brief description and illustrations, we identified our species as identical with Trachyoribates (Rostrozetes) glaber, known from Ecuador and Peru (see Beck 1965).
