Kryptochroma gigas gen. et sp. nov. can be distinguished by the elevated and short opisthosoma and by the heart-shaped epigynal plate with a short and stout projection over a wide median septum, which divides the median field in two longitudinal gutters reaching the copulatory openings (Figs 3C–F, 21A). Etymology The epithet is a Latin feminine noun that means giant, referring to the bigger size of this species compared to other species of the genus.
