 Type material: Holotype: male from FazendaArataú, Novo Repartimento, Pará, Brazil (04º02’40”S, 50º23’05.55”W), Jun. 25–26, 2003, Equipe IPAN leg., 1♁, deposited in MPEG 10909, PBI_OON 45144. Paratypes: same data as holotype, 1♁ (MPEG 37769, PBI _ OON 45144); Jun. 19/ Aug. 11–13, 2003, 1♁ (MPEG 10911 PBI _ OON 45821); 1♁ (MPEG 10912, PBI _ OON 45898).   
 Etymology. The specific name is a patronym in honor of Alexandre Ereba, a five-year-old boy from the tribe Ogoni, living in Port Harcourt’s waterfront, southeeastern Nigeria, who was named Alexandre in honor of the third author.   
 Diagnosis. Males of this species are similar to those of H. fannesi sp. nov. and H. periclitata sp. nov., by the endite’s P1 longitudinally oriented, posteriorly directed, reaching the anterior margin of sternum (Figs 17F, 19F, 21F) but differ by the tip of endite’s P1 twisted lateraly (Fig. 20C) (folded ventrally in H. fannesi sp. nov., Fig. 18C; not twisted or folded in H. periclitata sp. nov., Fig. 23B). Additionally, they can be recognized by the presence of a sternal postero-median concavity (Fig. 20A) (absent in H. fannesi sp. nov. and H. periclitata sp. nov.) and by the large, squared process of the prosoma pedicelar region (Figs 19D, 20B, G) (absent or semicircular in all other species of the genus).   
 Description. Male (PBI_OON 45144). Total length 1.64. CEPHALOTHORAX: Carapace pale orange, with Coxapopha -like pattern, pars cephalica with two posterior humps in lateral view, surface of elevated portion of pars cephalica smooth, sides finely reticulate, fovea present (Figs 19B–C). Eyes ALE oval, PME circular, PLE oval; posterior eye row recurved from above, straight from front; ALE separated by more than their diameter, ALE-PLE separated by less than ALE radius, PME touching, PLE-PME separated by less than PME radius (Fig. 19E). Sternum wider than long, pale orange, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, surface smooth, without pits, microsculpture everywhere but front, median concavity present (Figs 19D, 20B). Mouthparts: Chelicerae distal region abruptly narrowed (Figs 20A,D). Labium anterior margin anteriorly projecting at middle (Fig. 20C). Endites with a median projection (mp), a P1 and a P2; mp very short, with wide base and narrow tip, directed anteriorly; P1 long, directed posteriorly, reaching the anterior third of the sternum. P2 very short, situated anteriorly to P1 (Fig. 20C). ABDOMEN: dorsum soft portions white. Book lung covers small, very narrow. Dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible dorsally. Epigastric scutum not protruding. Postepigastric scutum pale orange, long, almost rectangular, covering nearly full length of abdominal length (Figs 19B,G, 20E). 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, as longer as embolus, with abruptly narrowed tip (Figs 19G–I, 20F,H–K).
