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. Spinneret scutum with fringe of needle-like setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus represented only by setae. LEGS: yellow, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I shorter than carapace, tibia IV specialized hairs on ventral apex absent, tibia IV ventral scopula absent, metatarsi III and IV weak ventral scopula absent.
