Endites distally not excavated, serrula present in single row, posteromedian part unmodified, same as sternum in sclerotization, with a lateral furrow that bisects the maxilla in two sections: a dorsal one, flattened, bearing the serrula, and a ventral one, thickened, almost cylindrical, with a truncate, less sclerotized apex. 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.

Postepigastric scutum weakly sclerotized, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum absent. Dorsum setae present, dark, needle-like. Epigastric area setae uniform, dark, needle-like. Postepigastric area setae present, dark, needle-like.

Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Epigastric region with sperm pore not visible; 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, widened, expanded tip; trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella basally; patella shorter than femur, not enlarged, setae unmodified; tibia trichobothria not examined; cymbium yellow, ovoid in dorsal view, fused with bulb but with clearly defined seam between, not extending beyond distal tip of bulb, plumose setae absent, without stout setae, without distal patch of setae; bulb white, more than 2 times as long as cymbium, stout, tapering apically, distal part abruptely narrowed, nearly straight until the embolus. Conductos very short, acute and inconspicuous.

            Female (PBI_OON 42). Total length 2.40. As in male except as noted. CEPHALOTHORAX: Carapace non-marginal pars cephalica setae most of them lost; non-marginal pars thoracica setae most of them lost. Eyes on dark pigment; ALE-PLE separated by less than ALE radius. Endites anteromedian tip unmodified, without the modifications of the male. Female palp claws absent; spines absent; tarsus unmodified. LEGS: yellow; femora femora IV slightly thickened. Tarsi I to IV superior claws tooth not examined in detail. Trichobothria not examined. GENITALIA: Ventral view: anterior receptacle divided in two parts: a ventral, T-shaped solid structure for muscle attachments, an a dorsal one, with thickened walls and covered with gland tissue, and with a dorsal, globose, membranous sac arising from the middle. A transverse bar, basally to the anterior receptacle, meet to the lateral ends of a posterior, similar, but procurved bar that support the apparently small posterior receptacle, that seems to be slightly sclerotized..
