            Female (PBI_OON 15034). Total length 2.20. As in male except as noted. CEPHALOTHORAX: Carapace yellowish white; non-marginal pars cephalica setae present in one row. Eyes ALE largest; PME touching. Sternum yellowish white. Mouthparts: Chelicerae, endites and labium yellowish white. Labium wide, with a procurved indentation; two subdistal normal setae.. Female palp claws absent; spines absent; tarsus unmodified. ABDOMEN: Posterior spiracles connected by groove. Dorsal scutum covering less than 1/2 of abdomen, between 1/4 and 1/2 abdomen width, yellowish-white. Epigastric scutum without lateral joints. Postepigastric scutum only around epigastric furrow, not fused to epigastric scutum, yellowish-white. LEGS: Leg spination (only surfaces bearing spines listed, all spines longer than segment width): (leg I: femur: pv0-0-1-1-1; rv0-0-1-1 tibia: v2-2-2-2-2-0 metatarsus: v2-2-0, leg II: femur: pv0-0-1-1-1; rv0-0-1-1 tibia: v2-2-2-2-2-0 metatarsus: v2-2-0, leg III: patella: d2 tibia: d2-2-1, v1ap, leg IV: patella: d2 tibia: d2-2-2, v1-2ap metatarsus: d2-2, v1ap. ). Tarsi I to IV superior claws tooth not examined in detail. Trichobothria not examined. GENITALIA: Ventral view: posterior margin of epigastric fold with a procurved chitinized ridge. Field in front snowwhite Laterally to this ridge, this species lacks the bracket-shaped sclerotized lines of A. vestigator.. Dorsal view: the internal genitalia consists in a short anterior element, with a thin lumen and a slightly widened tip. In the only female examined there is no traces of posterior receptacle. Two short lateral apodemes that looks anteriorly directed in the preparation, although this is probable an artifact of the montage..
