Hexapopha marajoara Feitosa & Ott & Bonaldo 2023, sp. nov.

Hexapopha marajoara sp. nov. Figs 82–84; Map 6 Type material: Holotype: male from Floresta Nacional de Caxiuan „, Melgaço, Pará, Brazil (01º44’15.5”S, 51º26’42.0”W), Apr. 01, 1996, E. Atrop. leg., deposited in MPEG 37966, PBI_OON 46364. Paratypes: same data as holotype 1♀ (MPEG 37967, PBI _ OON 46345); Jul. 01, 1996, B. Rufesc leg., 1♁ (MPEG 37970, PBI _ OON 46346); 1♁, 1♀ (MPEG 37968, PBI _ OON 46347); 1♀ (MPEG 37969, PBI _ OON 46353). Etymology. The specific name is an adjective that means the one who lives on the Marajó archipelago, in Pará. The name of the Marajó island came from the Tupi language, mibaraió, meaning the bulkhead of the sea. Diagnosis. Males ressemble those of H. ubicki s p. nov., H. quadraginta sp. nov. and H. ilhoa 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 and by the endite’s P1 transversally oriented, folded over itself, adjacent to mp and devoid of prolateral process (Figs 75C, 78C, 81C); they differ from those of H. ubicki s p. nov., by the endite’s P2 not laminar, with narrow apices (Fig. 84C) (laminar, with broad tip, in H. ubicki s p. nov.), from those of H. quadraginta sp. nov. by the conductor tip wide (Fig. 84H) (conductor tip acute in H. quadraginta sp. nov.) and from those of H. ilhoa sp. nov. by the conductor as long as the embolus (Fig. 84G, H) (longer than the embolus in Hexapopha ilhoa sp. nov.). Females are similar to those of H. corniculata sp. nov. and H. numerosa sp. nov. by the absence of postepigastric scape, the lip-shaped, wider than long postepigastric plate and by the copulatory opening positioned on postepigastric plate ventral surface (Figs 51F–H, 52K, 59G, 60J–L); they differ from those of H. corniculata sp. nov. by the U-shaped postepigastric plate (V-shaped in H. corniculata sp. nov.) and from those of H. numerosa sp. nov. by the strongly sclerotized, curved lateral apodemes (Figs 83G–H) (weakly sclerotized, straigt lateral apodemes in H. numerosa sp. nov.). Description. Male (PBI_OON 46364). Total length 1.60. CEPHALOTHORAX: Carapace orange-brown, without any pattern, pars cephalica with two posterior humps in lateral view, surface of elevated portion of pars cephalica smooth, sides granulate, fovea present (Figs 82B–C). Eyes ALE circular, PME circular, PLE 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. 82E). Sternum as long as wide, orange-brown, median concavity absent, with radial furrows between coxae I–II, II–III, III–IV, furrow with rows of small pits, radial furrow opposite coxae III absent, surface finely reticulate, without pits, microsculpture absent; prosoma pedicelar region with process (Figs 82D, 84A). Mouthparts: Chelicerae distal region abruptly narrowed (Fig. 82E). Labium anterior margin not indented at middle (Fig. 84C). Endites with a median projection (mp), a P1 and a P2; mp short, directed anteriorly; P1 lamellar, situated posteriorly to mp, directed anteriorly, tip bent prolaterally. P2 short, tip narrow, situated anteriorly to mp (Figs 82B–C). ABDOMEN: dorsum soft portions pale orange. Book lung covers small, very narrow. Dorsal scutum orange-brown, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum slightly protruding. Postepigastric scutum orange-brown, almost semicircular, covering nearly full length of abdominal length (Figs 82B,G). LEGS: yellow. GENITALIA: Epigastric region with sperm pore situated at level of anterior spiracles. Palp proximal segments yellow; embolus tip flattened, not bent upwards; conductor present, without projections, as long as embolus, tip flattened (Figs 82G–I, 84E–H). Female (PBI_OON 46345).As in male except as noted. Total length 1.61. CEPHALOTHORAX: Carapace pars cephalica strongly elevated in lateral view (Fig. 83B). Eyes ALE oval. Mouthparts: Chelicerae, endites and labium pale orange. Labium rectangular (Fig. 83D). GENITALIA: Ventral view: postepigastric plate short; postepigastric scape absent; copulatory orifice slit-shaped, the posterior end of the slit is slightly widened. Dorsal view: anterior genitalic process with small arms; genital duct coiled (Figs 83G–H, 84I–L). Other material examined. Brazil. Pará.
