            Female (PBI_OON 15035). Total length 1.83. CEPHALOTHORAX: Carapace pale orange, without any pattern, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, with rounded posterolateral corners, posterolateral edge without pits, posterior margin not bulging below posterior rim, posterolateral surface without spikes, surface of elevated portion of pars cephalica smooth, sides finely reticulate, thorax without depressions, fovea absent, without radiating rows of pits; lateral margin straight, smooth, without denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae light, needle-like, present, scattered; non-marginal pars thoracica setae absent; marginal setae absent. Clypeus margin unmodified, curved downwards in front view, vertical in lateral view, low, ALE separated from edge of carapace by less than their radius, median projection absent; setae absent. Chilum absent. Eyes six, well developed, ALE largest, ALE circular, PME oval, PLE oval; posterior eye row procurved from both above and front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching, PLE-PME touching. Sternum longer than wide, pale orange, uniform, not fused to carapace, median concavity absent, without radial furrows between coxae I-II, II-III, III-IV, radial furrow opposite coxae III absent, surface smooth, without pits, sickle-shaped structures absent, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins with narrow extensions between coxae, without posterior hump; setae sparse, light, needle-like, evenly scattered, originating from surface. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae straight, anterior face unmodified; without teeth on both promargin and retromargin; fangs directed posteriorly, shape normal, without prominent basal process, tip unmodified; setae light, needle-like, evenly scattered; paturon inner margin with pairs of enlarged setae, distal region unmodified, posterior surface unmodified, promargin unmodified, inner margin unmodified. Labium not fused to sternum, wide, with a procurved indentation; subdistal portion with unmodified setae, two subdistal normal setae.. Endites distally not excavated, anteromedian tip unmodified, posteromedian part unmodified. Female palp claws absent; spines absent; tarsus unmodified. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions white, without color pattern. Book lung covers large, elliptical, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, unmodified, scuto-pedicel region unmodified, scutum extending far dorsal of pedicel, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent, cuticular outgrowths near pedicel absent. Dorsal scutum weakly sclerotized, pale orange, without color pattern, covering about 1/2 of abdomen, more than 1/2 to most of abdomen width, not fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles. Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum weakly sclerotized, pale orange, short, almost rectangular, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified. Spinneret scutum absent. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus represented only by setae. LEGS: white, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I near as long as carapace, tibia I unmodified, tibia IV specialized hairs on ventral apex absent, tibia IV ventral scopula absent, metatarsi I and II meso-apical comb absent, metatarsi III and IV weak ventral scopula absent. 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: v2-2-2-2-0 metatarsus: v2-2-0, leg II: femur: pv0-0-1-1; rv0-0-1-1 tibia: v2-2-2-2-0 metatarsus: v2-2-0, leg III: tibia: d2-2, v1ap metatarsus: d2-2, v1ap. ). Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Shape: posterior margin of epigastric fold with a procurved chitinized ridge, strongly rebordered, with lateral internal reinforced sclerotizations. Field in front snowwhite Laterally to this ridge, this species lacks the bracket-shaped sclerotized lines of A. vestigator.. Ventral view: the internal genitalia consists in a short anterior element, proportionately thinner and longer than in A. katagarama, but smaller than of A. vestigator; it has also a thin lumen nut not the widened tip. In the only female examined there is only traces of posterior receptacle. Two short lateral apodemes posteriorly directed, slightly longer than in A. katagarama..
