Figs 95–97 ; Map 6

Type material: Holotype: male from Fazenda Experimental da UFAM Km 38, BR-174, Manaus, Amazonas, Brazil (02º38’55.8”S, 60º03’09.4”W), E.P. Franken & A.C.K. Silva leg., 1♁, deposited in INPA, PBI_OON 45473 . Paratypes: same data as holotype, 1♁ ( INPA, PBI _ OON 45469 ); 1♀ ( INPA, PBI _ OON 45472 ); 1♀ ( INPA, PBI _ OON 45475 ) .

Etymology. From Brazilian Portuguese, the specific name is an adjective referring to the inhabitants of Manaus, the municipality which harbors the type locality.

Diagnosis. Males resemble those of H. kropfi sp. nov., H. caboquinho sp. nov., H. grismadoi sp. nov. H. pithecia 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 , 89D , 91C , 92D , 100B ). They differ from those of H. kropfi sp. nov., H. caboquinho sp. nov. and H. grismadoi sp. nov. by the endite’s P1 slightly folded over itself ( Fig. 97C ) (strongly folded over itself in those species); from those of H. pithecia sp. nov. by the endite’s P1 club-shaped, with blunt tip ( Figs 92D,F ) (abruptly narrowed, with pointed tip in that species) and from those of H. pantaneira sp. nov. by the endite’s P2 not protruded, directed posteriorly ( Figs 97C, D ) (protruded, directed ventrally in H. pantaneira sp. nov.). Females resemble those of H. ilhoa sp. nov., m-scripta (Birabén) , H. pantaneira sp. nov. and H. pithecia sp. nov. by the presence of a V-shaped postepigastric scape fused to a broad (longer than wide or nearly as long as wide) postepigastric plate ( Figs 80G , 93G , 99G , 101G ). They differ from those of H. pithecia sp. nov. by the continuous lateral margins of the postepigastric plate (lateral margins excavated in H. pithecia sp. nov.); from those of H. ilhoa sp. nov., by the angular posterior margin of postepigastric plate (rounded in H. ilhoa sp. nov.); from those of m-scripta (Birabén) by the posterior margin of the postepigastric plate forming an angle smaller than 90º (nearly 120º in m-scripta ) and from those of H. pantaneira sp. nov. by the weakly sclerotized, straight apodemes ( Figs 96F–H ) (strongly sclerotized, curved in H. pantaneira sp. nov.).

Description. Male (PBI_OON 45473). Total length 1.40. CEPHALOTHORAX: Carapace pale orange, without any pattern, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides scaly, fovea present ( Figs 95B–C ). Eyes all oval; posterior eye row straight from above, procurved from front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching, PLE-PME separated by less than PME radius ( Fig. 95E ). Sternum wider than long, pale orange, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow with rows of small pits, surface smooth, without pits, microsculpture absent; prosoma pedicelar region with process ( Figs 95D , 97B ). Mouthparts: Chelicerae distal region unmodified ( Fig. 95E ). Labium anterior margin anteriorly projecting at middle, wider than long ( Fig. 97C ). Endites with a median projection (mp), a P1 and a P2; mp weakly sclerotized, not observed in SEM; P1 directed posteriorly, bent upwards, anterior and posterior margin serrated. P2 short, situated anteriorly to P1 ( Figs 95F , 97C–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 95B,G ). LEGS: yellow. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments yellow; embolus tip not bent upwards; conductor present, without projections, as long as embolus ( Figs 95G–I , 97F ).

Female (PBI_OON 45472). As in male except as noted. Total length 1.35. CEPHALOTHORAX: Sternum as long as wide, surface finely reticulate. Mouthparts: Chelicerae, endites and labium pale orange. Labium triangular, anterior margin indented at middle ( Figs 96D , 97H ). GENITALIA: Ventral view: postepigastric plate V-shaped; postepigastric scape present; copulatory orifice oval, situated behind elevated anterior margin of posterior ventral scutum in depression. Dorsal view: anterior genitalic process with relatively small, straight arms; the posterior uterine sclerite has a rather large oval opening in its anterior surface ( Figs 96G–H , 97K–L ).
