Type material: Holotype: male from Rondon , Paraná, Brazil (23°24’58.4”S, 52°47’03.0”W), Jul. 1952, F. Plaumann leg., 1♁, deposited in FMNH, PBI_OON 10115 . Paratype: Nova Teutônia , Santa Catarina , Brazil, (27°09’44.2”S, 52°24’42.7”W), Jul. 1955, F. Plaumann 1♁ ( IRSN, PBI _ OON 16409 ) .

Etymology. The specific name is a Latin adjective meaning devoid, alluding to the fact that the sites from where the types came from are currently almost depleted of their original vegetational cover.

Diagnosis. Males resemble those of H. ubicki sp. nov., H. quadraginta s p. nov., H. ilhoa sp. nov. and H. marajoara sp. nov. by the conductor approximately the same size of the embolus, without proximal projection, by the absence of endite’s P3 and endite’s P1 transversally oriented, folded over itself, adjacent to mp and devoid of prolateral process ( Figs 75C , 78C , 81C , 84C ); they are readily recognized by the conductor with bifid tip ( Fig. 47J ) (with single tip in H. ubicki sp. nov., H. quadraginta s p. nov., H. ilhoa sp. nov. and H. marajoara sp. nov.).

Description. Male (PBI_OON 10115). Total length 1.70. CEPHALOTHORAX: Carapace orange-brown, with Coxapopha -like pattern, pars cephalica with two posterior humps in lateral view, surface of elevated portion of pars cephalica smooth, sides granulate, fovea present ( Figs 46B–C ). Eyes ALE oval, PME circular, PLE oval; posterior eye row straight from both above and 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. 46E ). Sternum longer than wide, pale orange, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow smooth, surface finely reticulate, without pits, microsculpture everywhere but front ( Figs 46D , 47C ). Mouthparts: Chelicerae distal region unmodified. Labium anterior margin anteriorly projecting at middle, much wider than long. Endites with a median projection (mp), a P1 and a P2; mp short, lamellar, serrated; P1 lamellar, subsquared, bent upwards, adjacent to mp, anterior and posterior margins serrated. P2 short, tip narrow, situated anteriorly to mp ( Figs 46F , 47C–G ). ABDOMEN: dorsum soft portions pale orange. Book lung covers small, very narrow. Dorsal scutum pale orange, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum not protruding. Postepigastric scutum pale orange, long, almost rectangular, covering nearly full length of abdominal length ( Figs 46B,G ). LEGS: pale orange. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments pale orange; embolus tip flattened, not bent upwards; conductor present, with bifid tip, longer than embolus, tip wider than the base ( Figs 46G–I , 47H–L ).

Female. Unknown.
