Labium triangular, not fused to sternum, anterior margin deeply incised; with 6 or more setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, serrula present in single row, anteromedian tip unmodified, posteromedian part unmodified. Female palp claws absent; spines absent; tarsus unmodified. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions pale white, without color pattern. Book lung covers large, round, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, unmodified, scuto-pedicel region unmodified, scutum not extending far dorsal of pedicel, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent, cuticular outgrowths near pedicel absent. Dorsal scutum absent. Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, without lateral joints. Postepigastric scutum weakly sclerotized, yellow-brown, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum absent. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like. Dense patch of setae anterior to spinnerets absent. Colulus represented only by setae. LEGS: yellow-brown, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I longer than carapace, tibia I unmodified, tibia IV specialized hairs on ventral apex 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: tibiae: v2-2-2-2-0, metatarsi: v2-2-0, leg II: tibiae: v2-2-2-2-0, metatarsi: v2-2-0, leg III: tibiae: p1-0, v2subap, leg IV: tibiae: v1-1-2subap, metatarsi: p1, r1. ). Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Shape: anterior element narrow, slightly sinuous; there are not vsible structures at its connection site with the posterior receptacle, which is elongated, nearly pyriform. Copulatory opening not visible, posterior transverse plate present only, with lateral endings not forwardly directed, at levels of semicircular apodemes.
