Types. Holotype male from Acampamento Mutum (02°36’44.7”S 56°11’39.2”W), Platô do Rio Juruti , Juruti , Pará, Brazil, 5–22.XI.2007, D.F. Candiani & N.F. Lo-Man-Hung leg. ( MPEG 30522 , PBI_OON 00044455) . Paratype female from same locality (02°33’18.0”S 56o13’22.4”W), 03–08.X.2010, B.V.B. Rodrigues, N.C. Bastos & N.S. Abrahim leg. ( MPEG 30523 , PBI_OON 40684) .

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Males are similar to those of A. cachimbo sp. nov. and A. almeirim sp. nov. by the endites with prolateral process with two retrolateral protrusions ( Figs 18 , 79 , 119 ), but can be recognized by the combined presence of a short embolus and large, oblong basal protrusion of endites prolateral process ( Figs 118 ,–119). Females resemble those of A. cachimbo sp. nov. by the large mesial portion of internal genital sclerite ( Figs 131– 132 ), but can be recognized by the genital area with a wide posterior transversal lip ( Fig. 129 ) and shorter arms of internal genital sclerite ( Fig. 132 ).

Description. Male (PBI_OON 40529, Figs 107–117 ): Total length 1.44. CEPHALOTHORAX: Carapace orange-brown, ovoid in dorsal view, anteriorly narrowed to 0.49 times its maximum width or less, with rounded posterolateral corners, surface of elevated portion of pars cephalica granulate; non-marginal pars cephalica setae present, scattered. Clypeus high, ALE separated from edge of carapace by their radius or more. Eyes ALE–PLE touching, PME touching throughout most of their length, PLE–PME touching. Sternum orange-brown, furrow wrinkled, surface rugose, without pits, anterior margin with a row of small depressions, lateral margin with infracoxal grooves and anterior and posterior openings, setae evenly scattered. Mouthparts: paturon distal region unmodified. Labium rectangular; with 6 or more setae on anterior margin. Endites anteromedian tip with one strong, tooth-like projection. ABDOMEN: dorsum soft portions white. Posterior spiracles not connected by groove. Pedicel tube medium. Dorsal scutum pale orange, covering more than 3/4 of abdomen, no soft tissue visible from above, middle surface finely reticulate, sides finely reticulate. Postepigastric scutum pale orange, long, semicircular, covering nearly full length of abdominal length, without posteriorly directed lateral apodemes. LEGS: pale orange; patella plus tibia I shorter than carapace, metatarsi I and II meso-apical comb absent. Tarsi I to IV superior claws tooth examined in detail; tarsus IV superior claws with zero teeth on median surface of retroclaw. GENITALIA: Epigastric region with sperm pore situated between anterior and posterior spiracles. Palp: bulb yellow, 1 to 1.5 times as long as cymbium, embolus light, prolateral excavation present, small, lamellar, twisted, narrow at tip, with a large rounded prolateral aperture.

Female (PBI_OON_044426, Figs 126–131 , 134): Total length 1.79. As in male, except as noted. ABDOMEN: dorsum soft portions covered with gray spots. Pedicel slightly ribbed, scutum not extending far dorsal of pedicel. Epigastric scutum weakly sclerotized, epigastric scutum not surrounding pedicel dorsally. Postepigastric scutum weakly sclerotized, fused to epigastric scutum, with short posteriorly directed lateral apodemes. GENITALIA: anterior receptaculum longer than large, short posterior directed apodemas; short transversal sclerite ( Fig. 132 ).
