Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, tuberculate setal bases present at sides and front. Postepigastric scutum strongly sclerotized, pale orange, long, semicircular, covering nearly full length of abdominal length, fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. 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.

GENITALIA: Epigastric region with sperm pore large, circular, situated at level of anterior spiracles, rebordered; furrow without omega-shaped insertions, without setae. Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments yellow; embolus dark, prolateral excavation absent, projecting far ventral of bulb surface; trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella basally, slightly expanded; patella shorter than femur, not enlarged, without prolateral row of ridges, setae unmodified; tibia trichobothria not examined; cymbium yellow, ovoid in dorsal view, completely fused with bulb, no seam visible, extending beyond distal tip of bulb, plumose setae absent, without stout setae, with distal patch of setae; bulb yellow, 1 to 1.5 times as long as cymbium, stout, tapering apically, produced basally, with distinct knob just proximal and retrolateral to embolus origin;.
