Etymology. The specific name is a noun in apposition meaning forty in Latin. The name alludes to the number of days of a traditional quarantine and to the fact that this species was described during the COVID-19 pandemic.

Diagnosis. Males ressemble those of H. ubicki s p. nov., H. ilhoa sp. nov. and H. marajoara sp. nov. by the conductor nearly 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 , 81C , 84C ); they differ from those of H. ubicki s p. nov., by the endite’s P2 not laminar, with narrow apices ( Fig. 78C ) (laminar, with broad tip, in H. ubicki s p. nov.), and from those of H. ilhoa sp. nov. and H. marajoara sp. nov.) by the conductor tip narrow, acute ( Fig. 78G ) (conductor tip wide in H. ilhoa sp. nov. and H. marajoara sp. nov. Figs 81H , 84G ). Females differ from those of the other species with a narrow postepigastric plate (distinctly wider than long) bearing a small scape and with narrow book long covers, smaller than the width of pedicel opening ( H. ubicki s p. nov., H. kropfi sp. nov., H. santosi sp. nov. and H. izquerdoi sp. nov.; Figs 33F–H , 56F–H , 74F–H , 86F–H ) by the semicircular posterior margin of postepigastric plate (triangular in H. ubicki s p. nov. and H. izquerdoi sp. nov.), not elevated (elevated in H. santosi sp. nov.), lateral arms of the T-shaped genitalic process thin and by the narrow, multifolded duct ( Figs 77G–H , 78L ) (lateral arms of the T-shaped genitalic process thick; duct wide, with only three folds in Hexapopha kropfi sp. nov.).

Description. Male (PBI_OON 46384). Total length 1.46. CEPHALOTHORAX: Carapace dark red-brown, with Coxapopha -like pattern, pars cephalica with two posterior humps in lateral view, surface of elevated portion of pars cephalica smooth, sides granulate, fovea present ( Figs 76B–C ).

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 smooth, without pits, microsculpture absent, prosoma pedicelar region with process ( Figs 76D , 78B ).

P2 short, lamellar, tip narrow, situated anteriorly to mp and P1 ( Figs 76F , 78C–D ). ABDOMEN: dorsum soft portions orange-brown. Book lung covers small, very narrow. Dorsal scutum dark red-brown, covering full length of abdomen, no soft tissue visible from above. Epigastric scutum not protruding. Postepigastric scutum dark red-brown, almost semicircular, covering nearly full length of abdominal length, fused to epigastric scutum ( Figs 76B,G ). LEGS: orange-brown. GENITALIA: Epigastric region with sperm pore situated at level of posterior spiracles. Palp proximal segments orange-brown; embolus tip flattened, not bent upwards; conductor present, without projections, shorter than embolus, with gradually narrowed tip ( Figs 76G–I , 78E–H ).

Female (PBI_OON 46319). As in male except as noted. Total length 1.50. CEPHALOTHORAX: Carapace without any pattern, pars cephalica strongly elevated in lateral view ( Fig. 77B ). Clypeus low, ALE separated from margin of carapace by less than their radius ( Fig. 77E ). Mouthparts: Chelicerae, endites and labium orange-brown ( Fig. 77D ). GENITALIA: Ventral view: postepigastric plate very short forming a very short postepigastric scape; copulatory orifice slit shaped, very narrow, situated along the entire postepigastric plate. Dorsal view: anterior genitalic process with straight arms; two lateral apodemes present; genital duct long, coiled ( Fig. 76D ).
