Type material. Holotype: male from Estaç „o Ecológica do Una, Una, Bahia, Brazil (14º48’S, 39º02’W / 15º17’48”S, 39º04’28”W), Oct, 1999– Sept. 2000, M.F. Dias leg., deposited in IBSP 62547, PBI_OON 52428 . Paratypes: same data as holotype, 1♁ ( IBSP 64290 , PBI _ OON 46388 ); 2003, M.F. Dias, 1♁ ( IBSP 62552 , PBI _ OON 46410 ) .

Etymology. The specific name is a patronym honoring the arachnologist Antonio D. Brescovit (IBSP) in recognition of his great contribution to the Goblin Spiders PBI.

Diagnosis. Males resemble those of H. una sp. nov. by the presence of retromarginal sclerotized projections on the paturon ( Fig. 10E ), differing by the laminar endite’s P2 ( Fig. 10C ) (horn-shaped in H. una sp. nov., Fig. 8C ).

Description. Male (PBI_OON 52428). Total length 1.70. CEPHALOTHORAX: Carapace orange brown, with Coxapopha -like pattern, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides scaly, fovea present ( Figs 9B–C ). Eyes ALE circular, PME circular, PLE oval; posterior eye row straight from both above and 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. 9E ). Sternum as long as wide, orange-brown, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow smooth, surface smooth, without pits, microsculpture absent ( Figs 9D , 10A ). Mouthparts: Chelicerae paturon lateral face with one sclerotized projection; distal region unmodified ( Figs 9E–F , 10D ). Labium triangular, anterior margin not indented at middle ( Fig. 10B ). Endites with a median projection (mp), a P1, a P2, a P3, a P4 and a P5; mp short, directed anteriorly; P1 lamellar, bent upwards, situated laterally to mp, anterior margin serrated. P2 lamellar, situated anteriorly to mp. P3 short, situated anteriorly to P2. P4 lamellar, situated anteriorly to P2, laterally to P3. P5 short, situated anteriorly to P3 ( Fig. 10C ). ABDOMEN: dorsum soft portions pale orange, without color pattern. Book lung covers small, very narrow. Dorsal scutum orange-brown, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum not protruding. Postepigastric scutum orange-brown, long, semicircular, covering nearly full length of abdominal length. Dorsal area anterior with hair tufts ( Figs 9A–B,G ). LEGS: orange-brown. GENITALIA: Epigastric region with sperm pore situated posteriorly in relation to posterior spiracles. Palp proximal segments pale orange; embolus dark, not bent upwards; conductor absent ( Figs 9G–I , 10F–I ).

Female. Unknown.
