Type material: Holotype: male from Maçaranduba , Nova Ipixuna, Pará, Brazil (04º55’12”S, 49º10’02”W), MPEG team leg., 1♁, deposited in MPEG 37770, PBI_OON 45692 .

Etymology. The specific name is a patronym honoring the arachnologist Wouter Fannes (Royal Museum for Central Africa) recognizing his great contribution to the Goblin Spiders PBI.

Diagnosis. Males differ from those of other species with long endite’s P1 (reaching at least the anterior margin of the sternum) ( H. harveyi sp. nov., H. erebai sp. nov., H. periclitata sp. nov., H. delta sp. nov., H. tallitae sp. nov. and H. platnicki sp. nov.) as follows: from H. harveyi sp. nov. by the relatively shorter endite’s P1 (not surpassing the anterior margin of sternum, Fig. 18C ; reaching the middle of sternum in H. harveyi sp. nov., Fig. 16A ); from H. delta sp. nov., H. tallitae sp. nov. and H. platnicki sp. nov. by the longitudinal oriented endite’s P1 ( Fig. 18C ) (divergent in H. delta sp. nov., Fig. 25C ; convergent in H. tallitae sp. nov. and H. platnicki sp. nov., Figs. 28C , 31B ); from H. periclitata sp. nov. and H. erebai sp. nov., by the tip of endite’s P1 folded ventrally ( Fig. 18C ) (not folded in H. periclitata sp. nov., Fig. 23B ; twisted lateraly in H. erebai sp. nov., Fig. 20C ).

Description. Male (PBI_OON 45692). Total length 1.54. CEPHALOTHORAX: Carapace pale orange, with Coxapopha -like pattern, pars cephalica with two posterior humps in lateral view, surface of elevated portion of pars cephalica smooth, sides finely reticulate, fovea present ( Figs 17B–C ). Eyes ALE oval, PME squared, 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. 17E ). Sternum wider than long, pale orange, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, surface finely reticulate, without pits, microsculpture everywhere but front ( Figs 17D , 18B ). Mouthparts: Chelicerae distal region abruptly narrowed ( Fig. 17E ). Labium anterior margin anteriorly projecting at middle, wider than long ( Figs 18C–D ). Endites with a median projection (mp), a P1 and a P2; mp very short, with wide base and narrow tip, directed anteriorly; P1 long, directed posteriorly, with tip bent upwards, anterior margin serrated. P2 lamellar, situated anteriorly to P1, face retrolateral serrated ( Figs 18C–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. LEGS: white. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments white; embolus tip flattened, bent upwards; conductor present, without projections, longer than embolus ( Figs 17G–I , 18F–I ).

Female. Unknown.

Other material examined. None.

Distribution. Known from Novo Repartimento and Nova Ipixuna, state of Pará, Brazil ( Map 2 ).
