Dorsal scutum strongly sclerotized, without color pattern, covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles, orange. Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum strongly sclerotized, long, semicircular, covering about 2/3 of abdominal length, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes, orange. Spinneret scutum present, incomplete ring. Dorsum setae present, dark, needle-like. Epigastric area setae uniform, dark, needle-like. Postepigastric area setae present, dark, needle-like.

LEGS: pale orange, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I near as long as carapace, tibia I unmodified, tibia IV specialized hairs on ventral apex absent, tibia IV ventral scopula absent, metatarsi I and II meso-apical comb absent, metatarsi III and IV weak ventral scopula absent. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): (leg I: femora: pv0-0-1-0,
Tibiae: v2-2-2-2-0,
Metatarsi: v2-2-0, leg II: tibiae: v2-2-2-2-0,
Metatarsi: v2-2-0. ). Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Ventral view: postepigastric scutum with indented anterior margin; posterior receptacle visible by transparence, dark.. Dorsal view: internal female genitalia: anterior and posterior elements arising from a transverse sclerotized bar, with lateral apodemes posteriorly directed. Anterior element T-shaped, connected by muscles presumably to the lateral ends of the transverse bar; posterior receptacle worm-shaped, thick, initially is oriented backwards, describing -at its middle- a complete curve forward, becoming gradually thinner..
