Ventral and appendicularfeatures in Callichimaera perplexa n. gen. n. sp., from the mid-Cretaceous of Colombia.(A to C) Holotype IGM p881215.(A) Ventral view. (B) Close-up of sternal plates, sutures, and linea media (lm); the white arrow shows a spine in the third leg coxae. (C) Close-up of sternal crown, mandibles, and maxillipeds 2 and 3, the latter bearing a row of spines or crista dentata (cd) in the ischium. (D and E) Paratype IGM p881196.(D) Ventral view.(E) Close-up of sternum and sutures.(F) Paratype IGM p881185,showing details of the spanner-like claw.(G to I) Paratype IGM p881214.(G) Close-up of the large oar-like legs 2 and 3.(H) Ventral view showing the sternites, claws, legs, and pleon.

Phylogenetic relationships among the main families, superfamilies, and sections of “true” crabs or Brachyura. Tree topology after figs. S5 and S6. Each color and letter (encircled) represents one of the nine major brachyuran evolutionary branches.Dromiacea (red) (A) and Homoloida (purple) (B) are first known from the Jurassic, while †Callichimaeroida section nov. (dark blue) (C), †Torynommoida (light blue) (D), †Etyoida (dark green) (E), Raninoida (light green) (F), †Dakoticancroida (yellow) (G), Cyclodorippoida (orange) (H), and Eubrachyura or “higher” brachyurans (brown) (I) are all first known from the Cretaceous.Thick solid lines represent the ages of the first and last occurrences of each family within the main lineages. Dotted lines and daggers indicate extinct taxa; solid lines indicate living taxa. Black triangles indicate that in Anomura,decarcinization has occurred twice (anomuran clades not illustrated).White triangles indicate the three Brachyura lineages where decarcinization has occurred.
