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., 1♁, deposited in IBSP 65150, PBI_OON 52429 . Paratypes: same data as holotype, 1♁ ( IBSP 65231 , PBI _ OON 46405 ); 2♁ ( IBSP 62561 , PBI _ OON 51529 ); 1♁ ( IBSP 65141 , PBI _ OON 51565 ); 2003, M.F.

Etymology. The specific name is a patronym honoring the arachnologist Gustavo Rodrigo Sanches Ruiz (Universidade Federal do Pará) recognizing his great contribution to the Goblin Spiders PBI.

Diagnosis. Males differ from those of other species with conductor length half the embolus length or shorter ( H. santosi sp. nov., H. rheimsae sp. nov., H. itabaiana sp. nov. and H. ramirezi sp. nov., Figs 34J , 36J , 43I , 45J ) as follows: from H. santosi sp. nov. and H. rheimsae sp. nov., by the absence of a median concavity on the sternum ( Fig. 41B ); from H. itabaiana sp. nov. and H. ramirezi sp. nov. by the lamellar, anteriorly directed endite`s P1 ( Fig. 41D ) (transversal, not lamellar in H. itabaiana sp. nov. and H. ramirezi sp. nov.).

Description. Male (PBI_OON 52429). Total length 1.30. CEPHALOTHORAX: Carapace orange-brown, with Coxapopha-like pattern, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides finely scaly, fovea present ( Figs 40B–C ). Eyes ALE oval, 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 throughout most of their length, PLE-PME separated by less than PME radius ( Fig. 40E ). Sternum longer than wide, pale orange, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow smooth, surface smooth, without pits, microsculpture absent ( Figs 40D , 41B ). Mouthparts: Chelicerae distal region unmodified ( Fig. 40E ). Labium anterior margin not indented at middle, much wider than long ( Fig. 41D ). Endites with a median projection (mp), a P1, a P2 and a P3; mp very short, directed anteriorly; P1 lamellar, directed anteriorly, situated laterally to mp. P2 short, situated anteriorly to mp. P3 lamellar, directed anteriorly, situated posteriorly to P1 ( Figs 41C–E ). ABDOMEN: dorsum soft portions pale orange. Book lung covers large, ovoid. 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 ( Figs 40B,G , 41F ). LEGS: pale orange. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments pale orange; embolus dark, tip flattened, not bent upwards; conductor present, without projections, half the length of the embolus, broader at base ( Figs 40G–I , 41H–L ).

Female. Unknown.
