Figs 79–81; Map 5  
 Type material: Holotype: male from Reserva Biológica Marinha do Arvoredo, Florianópolis, Santa Catarina, Brazil, May 3–7, 1994, A.A. Lise et al., leg., deposited in MCN 6278, PBI_OON 46374. Paratypes: same data as holotype, 3♀ (MCN 6278, PBI _ OON 52496); May 15–16, 1994, 2♁, 1♀ (MCN 5029, PBI _ OON 46378).   
 Etymology. The species epithet, from Brazilian Portuguese, is a feminine noun in apposition, meaning the one that lives in an island, referring to the type locality, Ilha do Arvoredo, located 15 km from the coast of Santa Catarina, Brazil.   
 Diagnosis. Males ressemble those of H. ubicki s p. nov., H. quadraginta sp. nov. and H. marajoara 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 by the endite’s P1 transversally oriented, folded over itself, adjacent to mp and devoid of prolateral process (Figs 75C, 78C, 84C); they differ from those of H. ubicki s p. nov., by the endite’s P2 not laminar, with narrow apices (Fig. 81C) (laminar, with broad tip, in H. ubicki s p. nov.), from those of H. quadraginta sp. nov. by the conductor tip wide (Fig. 81H) (conductor tip acute in H. quadraginta sp. nov.) and from those of H. marajoara sp. nov. by the conductor longer than the embolus (Fig. 81H, I) (as long as the embolus in Hexapopha marajoara sp. nov.). Females resemble those of H. pithecia sp. nov., m-scripta (Birabén), H. pantaneira sp. nov. and H. manauara 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 93G, 96G, 99G, 101G). They differ by the rounded posterior margin of postepigastric plate (Figs 80F–H) (angular in those species).   
 Description. Male (PBI_OON 46374). Total length 1.50. CEPHALOTHORAX: Carapace dark red-brown, with Coxapopha -like pattern, pars cephalica strongly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides granulate, fovea absent (Figs 79B–C). Eyes ALE oval, PME circular, PLE oval; posterior eye row straight from above, procurved from 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. 79E). Sternum as long as wide, dark red-brown, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow with rows of small pits, surface finely reticulate, without pits, microsculpture absent; prosoma pedicelar region with small process (Fig. 79D, 81B). Mouthparts: Chelicerae distal region unmodified (Fig. 79E). Labium anterior margin anteriorly projecting at middle, much wider than long (Fig. 81C). Endites with a median projection (mp), a P1 and a P2; mp short, directed anteriorly; P1 lamellar, bent upwards, situated posteriorly to mp, anterior and posterior margins serrated. P2 short, tip narrow, bent downwards, situated anteriorly to mp (Figs 79F, 81C–D). ABDOMEN: dorsum soft portions orange-brown. Book lung covers small, very narrow. Dorsal scutum dark red-brown, without color pattern, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum, slightly protruding. Postepigastric scutum dark red-brown, almost semicircular, covering nearly full length of abdominal length, fused to epigastric scutum (Figs 79B,G). LEGS: orange-brown. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments pale orange; embolus tip flattened, not bent upwards; conductor present, without projections, longer than embolus, broader at base (Figs 79G–I, 81F–I).   
 Female (PBI_OON 46373). As in male except as noted. Total length 1.60. CEPHALOTHORAX: Carapace orange-brown, without any pattern (Fig. 80C). Eyes ALE separated by more than their diameter (Fig. 80E). Mouthparts: Chelicerae, endites and labium pale orange. Labium rectangular, anterior margin not indented at middle (Fig. 80D). ABDOMEN: dorsum soft portions pale orange. Postepigastric scutum orange-brown, covering about 3/4 of abdominal length (Figs 80A–B,F). GENITALIA: Ventral view: postepigastric plate short, V-shaped; postepigastric scape present; copulatory orifice slit shaped, very narrow, situated on the anterior margin of the postepigastric plate. Dorsal view: anterior genitalic process with slightly recurved arms; genital duct coiled (Figs 80G–H, 81J–L).
