How do I mount an SD card?

My SD card will suddenly not automount. It works on another Mac.

Can someone provide a solution to mount with Terminal?

$ diskutil list

/dev/disk2
#:                       TYPE NAME                    SIZE       IDENTIFIER
0:     FDisk_partition_scheme                        *16.0 GB    disk2
1:             Windows_FAT_32 NO NAME                 16.0 GB    disk2s1
