Figs 48–49 ; Map 3

Type material: Holotype: male from Parque Ecológico do Gunma , Santa Bárbara , Pará, Brazil (01°12’01.3”S, 48°17’53.7”W), Jan. 2008 – Jan. 2009, J.M.B. Pereira-Filho et al., leg., deposited in MPEG 37857, PBI_OON 45707 . Paratypes: same data as holotype, 2♁ (MPEG 37858, PBI _ OON 45712 ); 1♁ (MPEG 37860, PBI _ OON 45703 ) .

Etymology. The specific name is a toponymic referring to the type locality.

Diagnosis. Males resemble those of H. corniculata sp. nov., H. egua sp. nov. and H. izquierdoi sp. nov. by the conductor without proximal projection, with single tip and by the presence of endite’s P3 ( Figs 49C,G , 52C,G , 54C,J , 57D,G ); they can be distinguished from these species by the round booklung covers, approximately the width of pedicel opening ( Fig. 48G ) (booklung covers narrow, smaller than the width of pedicel opening in H. corniculata sp. nov., H. egua sp. nov. and H. izquierdoi sp. nov., Figs 50G , 53G , 55G ).

Description. Male (PBI_OON 45707). Total length 1.49. CEPHALOTHORAX: Carapace pale orange, with Coxapopha -like pattern, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides striated, fovea present ( Figs 48B–C ). Eyes ALE oval, PME circular, PLE 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. 48E ). Sternum longer than wide, pale orange, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow with rows of small pits, surface smooth, without pits, microsculpture absent ( Figs 48D , 49B ). Mouthparts: Chelicerae distal region unmodified ( Fig. 48E ). Labium anterior margin not indented at middle, much wider than long ( Fig. 49E ). Endites with a median projection (mp), a P1, a P2 and a P3; mp short, lamellar, directed anteriorly; P1 directed ventrally, bent upwards, situated posteriorly to mp. P2 short, situated anteriorly to mp. P3 lamellar, situated laterally to mp ( Figs 48F , 49C–E ). ABDOMEN: dorsum soft portions yellow. Book lung covers small, ovoid. Dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum not protruding. Postepigastric scutum pale orange, almost semicircular, covering nearly full length of abdominal length ( Figs 48B,G , 49F ). 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, shorter than embolus ( Figs 48G–I, 48G–I ).
