The female has an epigyne very similar to that in Thiratoscirtus gambari , but without a tongue-shaped posterior part (compare Fig. 67E with Fig. 65D ). Etymology This name is Latin, meaning ‘forest’, and refers to the habitat of this species. Fig. 65. Thiratoscirtus gambari Wesołowska & Russell-Smith, 2011 ,♀ (MNHN). A . Habitus, dorsal view. B .
