Figs 37–39 ; Map 3

Type material: Holotype: male from Mata do Crasto , Santa Luzia do Itanhy, Sergipe, Brazil (11º23’S, 37º24’W), Sept. 09–13, 1999, A.D. Brescovit et al., leg., deposited in IBSP 69439, PBI_OON 52612 . Paratypes: same data as holotype, 1♁ ( IBSP 69432 , PBI _ OON 52613 ); 1♁ ( IBSP 69429 , PBI _ OON 52611 ); 1♀ ( IBSP 69438 , PBI _ OON 52548 ); 1♀ ( IBSP 69436 , PBI _ OON 52549 ) .

Etymology. The specific name is a patronym honoring the arachnologist Xinping Wang (AMNH) recognizing his great contribution to the Goblin Spiders PBI, by developing the project´s data base.

Diagnosis. Males resemble those of H. brescoviti sp. nov. and H. una sp. nov. by the absence of a conductor ( Figs 8G , 10H , 39G ) and by the presence of a leaf-shaped endite`s P4 ( Figs 8C , 10C , 39D ); they differ from both species by the absence of cheliceral sclerotized projections ( Fig. 39C ) (present in H. brescoviti sp. nov. and H. una sp. nov.). Females differ from those of the other species with a narrow postepigastric plate (distinctly wider than long) bearing a small scape ( H. quadraginta s p. nov., H. kropfi sp. nov., H. santosi sp. nov., H. izquierdoi sp. nov. and H. ubicki sp. nov.; Figs 33H , 57J , 75J , 78J , 87J ) by the large booklung covers, approximately the width of pedicel opening diameter ( Fig. 38G ).

Description. Male (PBI_OON 52612). Total length 1.29. CEPHALOTHORAX: Carapace pale orange, with Coxapopha -like pattern, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides finely reticulate, fovea present ( Figs 37B–C ). Eyes all oval; posterior eye row recurved from above, straight from front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching, PLE-PME touching ( Fig. 37E ). 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 absent ( Figs 37D , 39A ). Mouthparts: Chelicerae slightly divergent, distal region unmodified ( Fig. 37E ). Labium anterior margin not indented at middle, much wider than long ( Figs 39C ). Endites with a median projection (mp), a P1, a P2, a P3, a P4 and a P5; mp very short, directed anteriorly; P1 very short, situated very close to mp, anterior margin serrated. P2 very short, situated laterally to mp. P3 situated anteriorly to P2. P4 large, lamellar, situated laterally to P5, covering mp, P1 and P2. P5 lamellar, situated anteriorly to P3 ( Figs 37B–C ). ABDOMEN: dorsum soft portions pale orange. Book lung covers large, ovoid. Dorsal scutum pale orange, without color pattern, covering full length of abdomen, no soft tissue visible dorsally. Epigastric scutum not protruding. Postepigastric scutum pale orange, almost semicircular, covering nearly full length of abdominal length ( Figs 37B, 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 ( Figs 37G–I , 39E–H ).

Female (PBI_OON 52549). As in male except as noted. Total length 1.33. CEPHALOTHORAX: Carapace without any pattern ( Figs 38B, C, E ). Mouthparts: Labium rectangular ( Fig. 38D ). ABDOMEN: Dorsal scutum covering more than 3/4 of abdomen, more than 1/2 to most of abdomen width. Postepigastric scutum short, almost rectangular, covering about 1/2 of abdominal length ( Figs 38A–B, F ). GENITALIA: Ventral view: postepigastric plate forming a short postepigastric scape; copulatory orifice circular, situated at the posterior margin of the postepigastric plate. Dorsal view: anterior genitalic process with procurved arms; distal part of genital duct strongly coiled ( Figs 38F–H , 39I–L ).
