Type material: Holotype: male from Fazenda Tanguro , Querência, Mato Grosso, Brazil (12º49’47.6”S, 52º27’28.0”W), May – Jun, 2006, D.F. Candiani & N.F. Lo Man Hung leg., deposited in MPEG 37882, PBI_OON 46087 . Paratypes: same data as holotype, 2♁ (MPEG 37883, PBI _ OON 46073 ) ; 1♁ (MPEG 37884, PBI _ OON 46104 ); 1♀ (MPEG 37885, PBI _ OON 46109 ); 1♀ (MPEG 37886, PBI _ OON 46111 ) .

Etymology. The specific name is a patronym honoring the arachnologist Christian Kropf (Natural History Museum, Bern), recognizing his great contribution to the Goblin Spiders PBI.

Diagnosis. Males resemble those of H. caboquinho sp. nov., H. grismadoi sp. nov. H. pithecia sp. nov., H. manauara sp. nov. and H. pantaneira sp. nov. by the conductor nearly the same size of the embolus, without proximal projection and with single tip, by the absence of endite’s P3 and endite’s P1 transversally oriented, folded over itself, devoid of prolateral process and separated from mp by more than its width ( Figs 89D , 91C , 92F , 97C , 100B ). They differ from those of H. pithecia sp. nov., H. manauara sp. nov. and H. pantaneira sp. nov. by the endite’s P1 strongly folded over itself ( Fig. 87C ) (sligtly folded over itself in those species); from those of H. caboquinho sp. nov. by the endite’s P1 with tip oriented anteriorly ( Fig. 87C ) (oriented medially in that species), and from those of H. grismadoi sp. nov. by the labium width less than two times its lenght ( Fig. 87C ) (more than two times its length in H. grismadoi sp. nov.). Females differ from those of the other species with a narrow postepigastric plate (distinctly wider than long) bearing a small scape and with narrow book long covers, smaller than the width of pedicel opening ( H. ubicki s p. nov., H. quadraginta sp. nov., H. santosi sp. nov. and H. izquerdoi sp. nov. ( Figs 33F–H , 56F–H , 74F–H , 77F–H ) by the semicircular posterior margin of postepigastric plate (triangular in H. ubicki s p. nov. and H. izquerdoi sp. nov.), not elevated (elevated in H. santosi sp. nov.), lateral arms of the T-shaped genitalic process thick and the wide duct, with only three folds ( Figs 77G–H , 78L ) (lateral arms of the T-shaped genitalic process thin; duct narrow, multifolded in H. quadraginta sp. nov.).

Description. Male (PBI_OON 46087). Total length 1.42. CEPHALOTHORAX: Carapace orange-brown, with Coxapopha -like pattern, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides scaly, fovea absent ( Figs 85B–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, PLE-PME separated by less than PME radius ( Fig. 85E ). Sternum as long as 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; with vestigial sclerotized triangle in male ( Figs 85D , 87B ). Mouthparts: Chelicerae distal region unmodified ( Fig. 85E ). Labium anterior margin anteriorly projecting at middle, wider than long ( Fig. 87C ). Endites with a median projection (mp), a P1 and a P2; mp lamellar, anterior margin serrated; P1 lamellar, bent upwards, situated posteriorly to mp. P2 situated laterally to mp ( Figs 85F , 87C–D ). ABDOMEN: dorsum soft portions pale orange. Book lung covers small, very narrow. Dorsal scutum orange-brown, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum not protruding. Postepigastric scutum orange-brown, almost semicircular, covering nearly full length of abdominal length ( Figs 85B–C ). 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, without projections, longer than embolus, broader at base ( Figs 85G–I , 87E–H ).

Female (PBI_OON 46109). As in male except as noted. Total length 1.42. CEPHALOTHORAX: Carapace without any pattern, pars cephalica slightly elevated in lateral view ( Fig. 86B ). Eyes posterior eye row recurved from above ( Fig. 86C ). Sternum longer than wide, surface smooth, microsculpture medially and in furrows. Mouthparts: Chelicerae, endites and labium pale orange. Labium rectangular, anterior margin not indented at middle ( Fig. 85D ). ABDOMEN: Postepigastric scutum long, almost rectangular ( Fig. 86F ). GENITALIA: Ventral view: postepigastric plate forming a vestigial postepigastric scape; copulatory orifice slit shaped, very narrow, situated along the entire postepigastric plate. Dorsal view: anterior genitalic process with small, recurved arms; genital duct forming three coils ( Figs 86G–H , 87I–L ).
