Platycryptus magnus is a species of jumping spider in the family Salticidae.

[1][2] It is found in Central America, has a large hairy body and is mostly gray.

They are very similar to other platycryptus, but differ from other members of their genus by having a moderate retrolateral tibial apophysis, a small bump on their pedipalp.

Previously, Marpissa broadwayi was mischaracterized as a separate species but they are synonymous.
