Kryptochroma is a genus of South American bark-dwelling crab spiders erected by M. Machado, R. Viecelli, and C. Guzati in 2021 after a phylogenetic analysis showed that Stephanopis contained two distinctly different clades. ^[2] The genus was created for the "pentacantha" clade, as well as for several newly described species. ^{[2] [1]}

Species

As of April 2022 ^[update] it contains nine species: ^[1]

• K. gigas Machado & Viecelli, 2021 – Brazil
• K. hilaris Machado & Teixeira, 2021 – Brazil
• K. macrostyla (Mello-Leitão, 1929) – Brazil
• K. parahybana (Mello-Leitão, 1929) – French Guiana, Brazil
• K. pentacantha (Mello-Leitão, 1929) (type) – Brazil
• K. quadrata Machado & Viecelli, 2021 – Brazil
• K. quinquetuberculata (Taczanowski, 1872) – Colombia, French Guiana, Brazil
• K. renipalpis (Mello-Leitão, 1929) – Brazil
• K. septata Machado & Teixeira, 2021 – Brazil
