Costaleg., deposited in MPEG 37806, PBI_ OON 45736).   Paratypes: same data as holotype, 1♁ (MPEG 37807, PBI_ OON 45749); 1♁, 2♀(MPEG 37808, PBI_ OON 45755). Barcarena ( 01º33’44”S, 48º33’51”W) MPEG team leg., 2♀(MPEG 37809, PBI_ OON 45806).   Etymology.The specific name is a patronym honoring the arachnologist Matias A. Izquierdo (Universidad Nacional de Córdoba, Argentina), recognizing his great contribution to the Goblin Spiders PBI.   Diagnosis.Males of this species resemble  H. corniculata  sp. nov.,  H. egua  sp. nov.and  H. gunma  sp. nov.by the conductor without proximal projection, with single tip and by the presence of endite’s P3 ( Figs 49C,G, 52C,G, 54C,L); they can be distinguished from those of  H. corniculata  sp. nov.by the lamellar endite’s P3 ( Fig. 57D); from those of  H. egua  sp. nov.the lamellar endite’s P1 ( Fig. 57D); from those of  H. gunma  sp. nov.by the narrow booklung covers, smaller than the width of pedicel opening ( Fig. 55G) (round, approximately the width of pedicel opening in  H. gunma  sp. nov., Fig. 48G). 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. quadragintas p. nov.,  H. kropfi  sp. nov.,  H. santosi  sp. nov., and  H. ubicki  sp. nov.; Figs 33F–H, 74F–H, 77F–H, 86F–H) by the posterior margin of postepigastric plate triangular (semicircular in  H. quadragintas p. nov.and  H. kropfi  sp. nov.), not elevated (elevated in  H. santosi  sp. nov.), highly sclerotized (weakly sclerotized in  H. ubicki  sp. nov.) ( Figs 56F–H).   Description. Male(PBI_OON 45736). Total length 1.47. CEPHALOTHORAX: Carapaceorange-brown, with  Coxapopha-like pattern, pars cephalicawith two posterior humps in lateral view, surface of elevated portion of pars cephalicasmooth, sides scaly, fovea present ( Figs 55B–C, 57A). EyesALE circular, PME circular, PLE oval; posterior eye row recurved from above, straight 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. 55E). Sternumas long as wide, orange-brown, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, surface smooth, without pits, microsculpture absent ( Figs 55D, 57B). Mouthparts: Chelicerae distal region abruptly narrowed ( Fig. 55E). Labium anterior margin anteriorly projecting at middle, wider than long ( Fig. 57C). Endites with a median projection (mp), a P1, a P2 and a P3; mp very short, directed anteriorly; P1 lamellar, directed ventrally, situated posteriorly to mp. P2 large, lamellar, situated anteriorly to P3, directed ventrally. P3 lamellar, situated anteriorly to P2, directed ventrally ( Figs 55F, 57C–E). 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, almost semicircular, covering nearly full length of abdominal length ( Figs 55B,G). LEGS: pale orange. GENITALIA: Epigastric region with sperm pore situated at level of anterior spiracles. Palp proximal segments pale orange; embolus tip flattened, not bent upwards; conductor present, longer than embolus, tip flattened ( Figs 55G–I, 57F–H).  Female(PBI_OON 45806). As in male except as noted. Total length 1.41. Carapacewithout any pattern, pars cephalicastrongly elevated in lateral view ( Fig. 56B). EyesPME oval. Sternumlonger than wide ( Fig. 56D). Mouthparts: Labium rectangular, anterior margin indented at middle ( Fig. 56D). GENITALIA: Ventral view: postepigastric plate forming a short postepigastric scape; copulatory orifice slit shaped, narrow, situated on the anterior elevated margin of the postepigastric plate. Dorsal view: anterior genitalic process with small, procurved arms ( Figs 56G–H, 57J–K).   Othermaterial examined.   Brazil. Pará.  Belém: Parque Estadual do Utinga( 01º25’21.8”S, 48º25’14.2”W),  Oct. 23–30, 2010, E.L.S.
