Type material: Holotype: male from Base de Operaçıes Geólogo Pedro de Moura , Porto Urucu , Coari, Amazonas, Brazil (04º53’45”S, 65º19’11”W), Oct. 2006, S.C. Dias et al., deposited in MPEG 37783, PBI_OON 45972 . Paratypes: same data as holotype, 1♁ (MPEG 37786, PBI _ OON 46360 ); Fazenda Experimental , Km 38, BR 174, Manaus, Amazonas, Brazil (02°39’21.23”S, 60°04’31.25”W), Jun. 26, 2009, B. Machado leg., 1♁ (MPEG 37784, PBI _ OON 45397 ) .

Etymology. The specific name, from Brazilian Portuguese, is a reference to the X-caboquinho, a typical sandwich from the state of Amazonas, made with buttered bread, curd cheese, tucum„ palm fruit and fried bananas.

Diagnosis. Males resemble those of H. kropfi sp. nov., H. grismadoi 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 87C , 91C , 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. 89D ) (sligtly folded over itself in those species); and from those of H. kropfi sp. nov. and H. grismadoi sp. nov. by the endite’s P1 with tip oriented medially ( Fig. 89D ) (oriented anteriorly in those species).

Description. Male (PBI_OON 45972). Total length 1.40. CEPHALOTHORAX: Carapace orange-brown, without any pattern, pars cephalica with two posterior humps in lateral view, surface of elevated portion of pars cephalica scaly, sides scaly, fovea present ( Figs 88B–C ). Eyes ALE circular, PME circular, PLE oval; posterior eye row recurved from above, straight from front; ALE separated by more than their diameter, ALE-PLE separated by less than ALE radius, PME separated by less than their radius, PLE-PME separated by less than PME radius ( Fig. 88E ). Sternum as long as wide, orange-brown, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow wrinkled, radial furrow opposite coxae III absent, surface smooth, without pits, microsculpture only in furrows ( Figs 88D , 89B ). Mouthparts: Chelicerae distal region unmodified ( Fig. 88E ). Labium anterior margin indented at middle, wider than long ( Fig. 89D ). Endites with a median projection (mp), a P1 and a P2; mp lamellar, anterior margin serrated; P1 directed posteriorly, bent prolaterally. P2 situated anteriorly to mp ( Figs 88F , 89C–D ). ABDOMEN: dorsum soft portions yellow. Book lung covers small, very narrow. Dorsal scutum orange-brown, covering full length of abdomen, no soft tissue visible from above. Epigastric not protruding. Postepigastric orange-brown, long, semicircular, covering nearly full length of abdominal length ( Figs 88B,G 89E ). LEGS: yellow. GENITALIA: Epigastric region with sperm situated at level of posterior spiracles. Palp proximal segments yellow; embolus tip flattened, not bent upwards; conductor present, without projections, as long as embolus, with gradually narrowed tip ( Figs 88G–I , 89F–I ).

Female. Unknown.
