Type material: Holotype: male from Parque Nacional de Sete Cidades , Piracuruca, Piauí, Brazil (04º06’09.6”S, 41º41’24.4”W), Jun. 24, 2007, L.S. Carvalho, M.P. Albuquerque & F.M. Oliveira‑Neto leg., 1♁, deposited in MPEG 37790, PBI_OON 45543 . Paratypes: same data as holotype 1♁ (MPEG 37802, PBI _ OON 45896 ); (04º07’25.9”S, 41º42’28.59”W), Jun. 27, 2007 , 1♁ (MPEG 37789, PBI _ OON 45542 ) .

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

Diagnosis. Males differ from those of other species with conductor length half the embolus length or shorter ( H. santosi sp. nov., H. rheimsae sp. nov., H. ruizi sp. nov. and H. itabaiana sp. nov., Figs 34J , 36J , 41J , 43I ) as follows: from H. santosi sp. nov. and H. rheimsae sp. nov., by the absence of a median concavity on the sternum ( Fig. 45B ); from H. ruizi sp. nov. by the endite`s P1 transversal, not lamellar ( Figs 45D–F ) (anteriorly directed, lamellar in H. ruizi sp. nov.); from H. itabaiana sp. nov. by the posterior end of carapace nearly straight in lateral view and by the abdominal scuta weakly sclerotized ( Figs 44B , 45A ) (posterior end of carapace angulated in lateral view, abdominal scuta strongly sclerotized in H. itabaiana sp. nov.).

Description. Male (PBI_OON 45543). Total length 1.64. 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 44B–C ). Eyes ALE circular, PME oval, 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. 44E ). Sternum longer than wide, yellow, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, surface smooth, without pits, microsculpture absent ( Figs 44D , 45B ). Mouthparts: Chelicerae distal region abruptly narrowed ( Fig. 44E ). Labium anterior margin anteriorly projecting at middle, wider than long ( Fig. 45C ). Endites with a median projection (mp), a P1 and a P2; mp short, hornlike, directed anteriorly; P1 very short, situated posteriorly to mp. P2 lamellar, situated anteriorly to mp and P1, anterior margin partly serrated ( Figs 44F , 45C–F ). ABDOMEN: dorsum soft portions yellow. Book lung covers small, very narrow. Dorsal scutum weakly sclerotized, yellow, covering 1/2 to 3/4 of abdomen, more than 1/2 to most of abdomen width. Epigastric scutum weakly sclerotized, not protruding. Postepigastric scutum weakly sclerotized, yellow, long, almost rectangular, covering about 3/4 of abdominal length ( Figs 44A–B,G ). LEGS: yellow. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments yellow; embolus tip flattened, not bent upwards; conductor present, without projections, half the length of the embolus, with tip needle-shaped ( Figs 44G–I , 45G–L ).

Female. Unknown.
