Figs 53–54 ; Map 5

Type material: Holotype: male from Fazenda Rio Capim , Goianésia , Pará, Brazil (03º18’50”S 48º28’54”W), Aug. 30, 2002, Equipe IPAN leg., 1♁, deposited in MPEG 10849, PBI_OON 46279. Patatype: same data as holotype, 1♁ (MPEG 10863, PBI _ OON 45817 ).

Etymology. The specific epithet is a noun in apposition from Brazilian Portuguese, referring to a popular interjection of surprise used by the people of Pará.

Diagnosis. Males of this species resemble those of H. corniculata sp. nov., H. izquierdoi sp. nov. and H. gunma sp. nov. by the conductor without proximal projection, with single tip and by the presence of endite’s P3 ( Figs 49C,G , 52C,G , 57D,G ); they differ from those of H. gunma sp. nov. by the narrow booklung covers, smaller than the width of pedicel opening, and from those of H. corniculata sp. nov. and H. izquierdoi sp. nov. by the narrow, horn-shaped endite’s P1 ( Figs 54C,E ) (wide, folded plates in H. corniculata sp. nov. and H. izquierdoi sp. nov.).

Description. Male (PBI_OON 46279). Total length 1.30. CEPHALOTHORAX: Carapace pale orange, without any pattern, pars cephalica with two posterior humps in lateral view, surface of elevated portion of pars cephalica smooth, sides scaly, fovea present ( Figs 53B–C ). Eyes all oval; posterior eye row straight from above, procurved from front; ALE separated by their radius to diameter, ALE-PLE separated by less than ALE radius, PME touching, PLE-PME separated by less than PME radius ( Fig. 53E ). Sternum as long as wide, pale orange, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, surface smooth, without pits, microsculpture absent ( Figs 53D , 54B ). Mouthparts: Chelicerae distal region unmodified ( Fig. 53E ). Labium anterior margin anteriorly projecting at middle, wider than long ( Fig. 54C ). Endites with a median projection (mp), a P1, a P2 and a P3; mp very short; P1 hornlike, relatively short, directed ventrally, situated laterally to mp. P2 large, lamellar, situated anteriorly to P1, bent ventrally. P3 lamellar, situated anteriorly to P2 ( Figs 53F , 54C–E ). ABDOMEN: dorsum soft portions pale orange. Book lung covers small, very narrow. Dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum not protruding, small. Postepigastric scutum pale orange, almost semicircular, covering nearly full length of abdominal length ( Figs 53B,G , 54B ). LEGS: yellow. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments yellow; embolus tip flattened, not bent upwards; conductor present, without projections, longer than embolus ( Figs 53G–I , 54G–L ).

Female. Unknown.
