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, with a truncated, less sclerotized tip, but with a ventral medial slerotized ridge.. 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, elliptical, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove.

Dorsal scutum absent. Epigastric scutum weakly sclerotized, not surrounding pedicel, not protruding, small lateral sclerites absent. 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. Spinneret scutum without fringe of setae. Dense patch of setae anterior to spinnerets absent. Colulus absent.

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 white; embolus dark, prolateral excavation absent, upwardly directed, relatively short; 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 white, ovoid in dorsal view, not fused with bulb, not extending beyond distal tip of bulb, plumose setae absent, without stout setae, without distal patch of setae; bulb white, 1 to 1.5 times as long as cymbium, stout, tapering apically, with a ventral basal bulge, middle part tapering abruptly, distal part conductor short, darkened.

            Female (PBI_OON 14953). Total length 2.46. As in male except as noted. CEPHALOTHORAX: Carapace non-marginal pars cephalica setae seem to be lost; non-marginal pars thoracica setae absent, seem to be lost. Clypeus setae seem to be lost. Eyes on dark pigment. Endites anteromedian tip unmodified, without the modifications of the male. Female palp claws present; spines absent; tarsus unmodified. LEGS: femora missing. Tarsi I to IV superior claws tooth not examined in detail. Trichobothria not examined. GENITALIA: Ventral view: aterior receptacle with two elements: a ventral one, long, distally widened, as a site for muscle attachment; and a dorsal one with thick walls covered with glands, its base is transverserly wide, the median part is strongly narrowed and forwardly directed, which is continued with the additional membranose, elongated sac. Transverse ventral ridge with a median deep identation; posterior receptacle inconspicuous (probably broken during the microscopis preparation)..
