Postepigastric scutum strongly sclerotized, orange-brown, long, semicircular, covering nearly full length of abdominal length, fused to epigastric scutum, anterior margin unmodified, with short posteriorly directed lateral apodemes, groove connecting posterior spiracles continued almost to lateral margins. Spinneret scutum present, incomplete ring. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like. Spinneret scutum with fringe of long setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus present. LEGS: yellow-brown, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I shorter than 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.
