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 64393, PBI_OON 46398 . Paratypes: same data as holotype, 1♁, 1♀ ( IBSP 64217 , PBI _ OON 51531 ); 1♁ ( IBSP 64397 , PBI _ OON 51569 ); 1♁, 2♀ ( IBSP 64441 , PBI _ OON 51576 ); 2♁ ( IBSP 65215 , PBI _ OON 52422 ) .

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

Diagnosis. Males resemble those of H. brescoviti sp. nov. by the presence of retromarginal sclerotized projections on the paturon ( Figs 6F , 8D ), differing by the horn-shaped P2 on the endite ( Fig. 8C ) (laminar in H. brescoviti sp. nov., Fig. 10C ). Females resemble those of H. hone , H. baehrae sp. nov. and H. brasiliana (Bristowe) by the Ushaped postepigastric scape fused to a broad postepigastric plate ( Figs 62G–H ; 68G–H ; Platnick et al., 2014, figs 85–86) but can be distinguished by the wide genital duct that almost reach the posterior portion of postepigastric plate ( Figs 7G–H ) (genital duct narrow, situated on the anterior portion of the postepigastric plate in H. hone , H. baehrae sp. nov. and H. brasiliana ). Additionally, they are distinguished from those of all other species of the genus by the genital duct forming a loop and returning to postepigastric plate ( Fig. 8L ).

Description. Male (PBI_OON 46398). Total length 1.81. 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 granulate, fovea present ( Figs 6B–C ). Eyes ALE circular, PME oval, PLE oval; posterior eye row straight from both above and front; ALE separated by their radius to diameter, ALE-PLE touching, PME touching throughout most of their length, PLE-PME separated by less than PME radius ( Fig. 6E ). Sternum as long as wide, orange-brown, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, surface smooth, without pits, microsculpture absent; prosoma pedicelar region with small process ( Figs 6D , 8A ). Mouthparts. Chelicerae paturon lateral face with one sclerotized projection; distal region abruptly narrowed ( Figs 6E , 8D ). Labium anterior margin anteriorly projecting at middle, much wider than long ( Fig. 8B ). 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 hornlike, 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 ( Figs 8B–C ). ABDOMEN: dorsum soft portions orange-brown. Book lung covers large, elliptical. Dorsal scutum orange-brown, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum slightly protruding. Postepigastric scutum orange-brown, almost semicircular, covering nearly full length of abdominal length, fused to epigastric scutum ( Figs 6A–B, G ). LEGS: orange-brown. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments pale orange; embolus dark, not bent upwards; conductor absent ( Figs 6G–I , 8E–F ).

Female (PBI_OON 51531). As in male except as noted. Total length 1.62. CEPHALOTHORAX: Carapace without any pattern, pars cephalica slightly elevated in lateral view, sides striated ( Figs 7B–C ). Eyes PME circular; ALE-PLE separated by less than ALE radius, PME touching ( Fig. 7E ). Sternum longer than wide, without radial furrows between coxae I–II, II–III, III–IV ( Fig. 7D ). Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae paturon lateral face without projection. Labium rectangular ( Figs 7D–E ). ABDOMEN: Dorsal scutum covering more than 3/4 of abdomen, more than 1/2 to most of abdomen width. Epigastric scutum not protruding. Postepigastric scutum covering about 3/4 of abdominal length ( Figs 7A–B,F ). GENITALIA: Ventral view: postepigastric scape present; copulatory orifice circular, very small, situated on the posterior margin of the scape. Dorsal view: anterior genitalic process with recurved arms; genital duct wide, not coiled ( Figs 7G–H , 8J–L ).
