Figs 90–91 ; Map 5

Type material: Holotype: male from Campo de Provas Brigadeiro Velloso , Serra do Cachimbo, Novo Progresso, Pará, Brazil (09º22’02.9”S, 55º01’11.9”W), Sept. 07–17, 2003, A. B. Bonaldo et al., leg., deposited in MPEG 37879, PBI_OON 45883 . Paratypes: same data as holotype, 1♁ (MPEG 37876, PBI _ OON 45879 ); 1♁ (MPEG 37878, PBI _ OON 45881 ) .

Etymology. The specific name is a patronym honoring the arachnologist Cristian Grismado (Museu Argentino de Ciencias Naturales Bernardino Rivadavia), recognizing his great contribution to the Goblin Spiders PBI.

Diagnosis. Males resemble those of H. kropfi sp. nov., H. caboquinho sp. nov. H. pithecia sp. nov., H. manauara sp. nov. and H. pantaneira sp. nov. by the conductor approximately 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 97C , 89D , 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. 91C ) (sligtly folded over itself in those species); from those of H. caboquinho sp. nov. by the endite’s P1 with tip oriented anteriorly ( Fig. 91C ) (oriented medially in that species), and from those of H. kropfi sp. nov. by the labium width more than two times its length ( Fig. 91C ) (less than two times its lenght in H. kropfi sp. nov.).

Description. Male (PBI_OON 45883). Total length 1.33. CEPHALOTHORAX: Carapace pale orange, without any pattern, pars cephalica with two posterior humps in lateral view, surface of elevated portion of pars cephalica smooth, sides striated, fovea present ( Figs 90B–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. 90E ). Sternum longer than wide, pale orange, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow smooth, surface smooth, without pits, microsculpture only in furrows ( Figs 90D , 91B ). Mouthparts: Chelicerae distal region abruptly narrowed ( Fig. 90E ). Labium anterior margin anteriorly projecting at middle, much wider than long ( Fig. 91D ). Endites with a median projection (mp), a P1 and a P2; mp lamellar; P1 lamellar, situated posteriorly to mp, bent upwards, anterior and posterior margins serrated. P2 lamellar, tip narrow, situated anteriorly to mp ( Figs 90F , 91C– E ). ABDOMEN: dorsum soft portions yellow. 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, almost semicircular, covering nearly full length of abdominal length ( Figs 90B,G , 91F ). LEGS: yellow. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments yellow; embolus not bent upwards; conductor present, without projections, shorter than embolus, broader at base ( Figs 90G–I , 91G–K ).

Female. Unknown.
