Figs 42–43; Map 3  
 Type material: Holotype: male from Estaç „o Ecológica da Serra Itabaiana, Itabaiana, Sergipe, Brazil (10º40’S, 37º25’W) Oct. 14–20, 1999, A.D. Brescovit et al., leg., 1♁, deposited in IBSP 68166, PBI_OON 52525. Paratypes: same data as holotype, 1♁ (IBSP 68163, PBI _ OON 52568); 1♁ (IBSP 68162, PBI _ OON 52584).   
 Etymology. The specific name is a toponymic referring to the type locality.   
 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. ruizi sp. nov. and H. ramirezi sp. nov., Figs 34J, 36J, 41J, 45J) as follows: from H. santosi sp. nov. and H. rheimsae sp. nov., by the absence of a median concavity on the sternum (Fig. 43B); from H. ruizi sp. nov. by the endite`s P1 transversal, not lamellar (Fig. 43D) (anteriorly directed, lamellar in H. ruizi sp. nov.); from H. ramirezi sp. nov. by the posterior end of carapace angulated in lateral view and by the abdominal scuta strongly sclerotized (Figs 42B, 43A) (posterior end of carapace nearly straight in lateral view, abdominal scuta weakly sclerotized in H. ramirezi sp. nov.).   
 Description. Male (PBI_OON 52525). Total length 1.67. CEPHALOTHORAX: Carapace pale orange, with Coxapopha -like pattern, pars cephalica domed in lateral view, surface of elevated portion of pars cephalica smooth, sides finely reticulate, fovea present (Figs 42B–C). Eyes ALE circular, 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 throughout most of their length, PLE-PME separated by less than PME radius (Fig. 42E). Sternum longer than wide, pale orange, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, surface smooth, without pits, microsculpture absent (Figs 42D, 43B). Mouthparts: Chelicerae distal region unmodified (Fig. 42E). Labium anterior margin not indented at middle, much wider than long (Fig. 42D). Endites with a median projection (mp), a P1 and a P2; mp short, directed anteriorly; P1 very short, situated laterally to mp. P2 lamellar, situated anteriorly to mp (Figs 43C–E). ABDOMEN: dorsum soft portions pale orange. Book lung covers large, 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 42B,G, 43F). LEGS: pale orange. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments pale orange; embolus tip flattened, conductor present, without projections, shorter than embolus (Figs 42G–I, 43H–I).

 Other material examined. None.
