            Female (PBI_OON 15080). Total length 2.30. As in male except as noted. CEPHALOTHORAX: Carapace broadly oval in dorsal view; non-marginal pars cephalica setae dark, needle-like; non-marginal pars thoracica setae dark, needle-like. Sternum the deep anterior incision of the sternum (where fits the posteriorly elongated labium) determine an elongated heart-shape.. Mouthparts: Chelicerae, endites and labium yellow. Chelicerae chelicerae and endites yellow, labium slightly orangish, not so sclerotized as in the male.; setae dark. Labium triangular, with a pointed backwards prolongation, deeply incident in the anterior margin of the sternum (although not so extremely as in the male). Endites distally not excavated, anteromedian tip unmodified. Female palp claws absent; spines absent; tarsus unmodified. ABDOMEN: dorsum soft portions light grey. Epigastric scutum without lateral joints. LEGS: femora femora III and IV thickened.. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): (leg I: femur: pv0-0-0-1-1 tibia: v2-2-2-2-2-0 metatarsus: v2-2-2-2, leg II: femur: pv0-0-0-1-1 tibia: v2-2-2-2-2-0 metatarsus: v2-2-2-2, leg III: femur: d1-1 tibia: d2-2, v1 metatarsus: d2-2; v2-3-2ap, leg IV: femur: d1-1-1 tibia: d2-1-2; v1 metatarsus: d2-2-1; v1-1-2ap. ). Tarsi I to IV superior claws tooth not examined in detail. Trichobothria not examined. GENITALIA: Shape: the genital opening connects to the uterus externus, from which two elements emerge: one anterior receptaculum and a posterior plate, with an anterior concavity. The long anterior receptacle have accesory glands and a set of muscles attached anteroventrally, presumably to the ventral cuticle, and one pair to the lateral projections of a sclerotised posterior plate. The anterior part of the posterior plate have a wide U-shaped margin.. Dorsal view: anterior receptaculum relatively short, gradually widened to anterior, with an elongated stalk and a mushroom-shaped distal "head". The accesory glands are in the distal part of the stalk. U-shaped sclerotised ridge at its base; there is no evident the locking mechanism between anterior and posterior receptacula, rather a membranous, longitudinal opening..
